We stock the materials that professionals in the pressure washing and soft washing industries need, polypropylene and PVC ball valves, cam and groove couplings, chemical-resistant tubing, CPVC fittings, metering pumps, and flow control accessories, all rated for the bleach and chemical cleaning solutions that destroy standard components, available from a single source with same-day fulfillment and no minimum order.


AN IMPORTANT NOTE ON MATERIALS
Why Material Selection Matters in Soft Washing and Pressure Washing

Sodium hypochlorite, the bleach solution at the heart of every soft wash system, is one of the most corrosive and oxidizing chemicals in routine professional use. It attacks standard brass and bronze fittings rapidly, degrades inappropriate elastomers in pump seals and valve seats within weeks, and corrodes standard metal cam and groove couplings through direct contact and airborne off-gassing alone. Building a soft wash rig or chemical delivery system with the wrong materials doesn't just shorten component life, it creates leaks, failures, and downtime on the job.

Polypropylene, PVC, and CPVC are the correct material families for bleach-contact components. The Alsco catalog is built around these materials, and our team understands why they matter in your specific application.


SOFT WASHING CHEMICAL DELIVERY SYSTEMS
Bleach-Compatible Components That Go the Distance

A professional soft wash rig lives and dies by the reliability of its chemical delivery system. From the bulk storage tank through the metering block, the pump, and out to the nozzle, every component that contacts sodium hypochlorite solution needs to be built from materials that bleach can't attack. One incorrect material in the flow path, a brass fitting, a standard rubber seal, a vinyl tube that hardens and cracks, is a failure point that takes the rig down in the field.

Bleach Corroding Metal Valves, Fittings, and Cam and Groove Couplings on Soft Wash Rigs

The pain: Standard brass ball valves, aluminum cam and groove couplings, and metal fittings in a soft wash system don't last a season under regular sodium hypochlorite exposure. Bleach oxidizes brass rapidly, corrodes aluminum at the surface and internally, and produces corrosion byproducts that contaminate the chemical mix. Replacing corroded metal hardware on an active rig is a recurring cost that comes out of job margin.
The Alsco Advantage: Polypropylene ball valves and cam and groove couplings, PVC fittings, and CPVC components are fully compatible with sodium hypochlorite at the concentrations used in professional soft washing, no corrosion, no contamination, and no season-to-season replacement cycle driven by bleach attack. Polypropylene cam and groove couplings specifically are the correct material for bleach-contact connections on soft wash rigs, providing the secure, quick-connect chemical transfer that the job requires, in a material that bleach can't destroy.

Chemical Tubing Hardening, Cracking, and Leaking Under Bleach Exposure

The pain: Standard clear vinyl tubing installed on soft wash rigs hardens and becomes brittle under sustained sodium hypochlorite exposure, particularly in the outdoor, UV-exposed environments where soft wash equipment operates. Hardened tubing cracks at fitting connections, creates leak points that expose operators to bleach solution, and requires replacement on a timeline measured in weeks rather than seasons.
The Alsco Advantage: Chemical-resistant tubing in polypropylene and specifically formulated PVC configurations maintains flexibility and integrity under bleach and surfactant chemistry exposure, resisting the hardening and cracking that standard vinyl tubing develops in sodium hypochlorite service. Pairing chemical-resistant tubing with polypropylene fittings and cam and groove couplings creates a complete bleach-compatible delivery path from tank to nozzle that holds up through a full working season and beyond.

Metering Block Valves Failing to Hold Position or Seal Under Repeated Cycling

The pain: A soft wash metering block depends on its valves holding precise positions to maintain the chemical mix ratio the job requires, and sealing completely when closed to prevent unwanted chemical bleed-through between mix points. Valves with degraded seats, sticky operators from bleach residue buildup, or bodies attacked by chemical exposure lose position repeatability and tight shutoff, creating mix ratio drift that affects cleaning results and chemical efficiency.
The Alsco Advantage: PVC and polypropylene ball valves with EPDM or FKM seats rated for sodium hypochlorite service provide the tight, repeatable shutoff that metering block positions require, with quarter-turn operation that holds position consistently under the flow pressures of a soft wash delivery system. Their smooth thermoplastic bodies resist the bleach residue adhesion that causes metal and inappropriate plastic valves to become sticky and difficult to operate after weeks in service.

Chemical Transfer from Bulk Bleach Containers Creating Spill and Exposure Risk

The pain: Transferring sodium hypochlorite from 55-gallon drums or bulk totes to rig tanks manually, lifting, tilting, pouring, creates spill risk on the job site, operator skin and clothing exposure to concentrated bleach solution, and the kind of incident that damages customer property and professional reputation simultaneously. Concentrated sodium hypochlorite on a driveway, deck, or landscape is not a minor housekeeping matter.
The Alsco Advantage: Polypropylene drum pumps with chemical-resistant tubing allow controlled sodium hypochlorite transfer from bulk containers without manual lifting or pouring, keeping bleach transfer contained, repeatable, and off the surfaces and personnel it's not supposed to contact. Polypropylene cam and groove couplings at the drum outlet and tank inlet provide secure, spill-controlled connections that eliminate the free-pour risk of manual transfer on a job site or in the shop.

PRESSURE WASHING RIG PLUMBING & FLOW CONTROL
The Plumbing Your Rig Depends On, From Tank to Trigger

Whether you're plumbing a new soft wash trailer, rebuilding a rig that's seen better days, or sourcing replacement components for an active fleet, the valves, fittings, tubing, and flow control components that go into a professional washing rig need to be rated for the chemistry in the tank and available without a week's lead time when the next job is scheduled.

Sourcing Bleach-Compatible Rig Components from Multiple Suppliers Wastes Time

The pain: A soft wash rig rebuild or new build requires valves, fittings, cam and groove couplings, tubing, check valves, strainers, and pressure gauges, all in materials compatible with sodium hypochlorite and surfactant chemistry. Sourcing those components from three or four different suppliers means multiple orders, staggered arrivals, and the risk that one back-ordered item holds up the completed build while a booked job sits on the calendar.
The Alsco Advantage: Alsco stocks the full range of bleach-compatible rig plumbing components in one catalog, PVC and polypropylene ball valves, PP cam and groove couplings, chemical-resistant tubing, check valves, line strainers, pressure gauges, and fittings in PVC, CPVC, and polypropylene configurations. One order. One delivery. No minimum. Same-day shipping means a rig component order placed today arrives tomorrow, not next week.

Strainers Absent or Wrong Material Allowing Debris to Damage Pumps and Nozzles

The pain: A soft wash pump running without an inlet strainer, or with a strainer in a material that bleach has degraded, ingests particulate that wears pump components and clogs nozzle tips on the job. A clogged nozzle or damaged pump on a roof wash or house wash job doesn't just create a service call. It creates downtime on a job that was already scheduled.
The Alsco Advantage: Thermoplastic line strainers in PVC and polypropylene installed on chemical inlet lines intercept particulate before it reaches pumps and nozzles, protecting equipment from the abrasive and organic debris that finds its way into bulk chemical storage tanks. In materials fully compatible with sodium hypochlorite and cleaning chemistry, they don't become the next corrosion failure that needs replacing after the pump they were supposed to protect.

No Flow Verification on Chemical Delivery Systems Creating Mix Ratio Uncertainty

The pain: A soft wash operator who doesn't know the actual flow rate coming through their chemical delivery system, because metering is done by valve position feel and experience rather than measured flow, introduces variability into every mix. Inconsistent sodium hypochlorite concentration means inconsistent cleaning results on jobs where the customer is paying for a specific outcome, and wasted chemistry on mixes that run stronger than necessary.
The Alsco Advantage: Blue-White variable-area flow meters installed on chemical delivery lines provide visible, real-time flow confirmation, allowing operators to verify and set chemical flow rates precisely rather than relying on valve position estimation. For operators building professional, repeatable systems that deliver consistent results across a fleet of rigs, inline flow measurement is the component that replaces guesswork with verified, documented mix ratios.

CAR WASH FACILITY SYSTEMS
The Facility Infrastructure Behind Every Wash Bay

Commercial car wash facilities, automatic conveyor washes, in-bay automatics, and self-serve bays, operate on continuous chemical delivery systems, recirculating water infrastructure, and plumbing that handles detergents, degreasers, wax and rinse aid concentrates, and the high-volume water recirculation that modern water-efficient car washes depend on. The piping and flow control components in those systems need to hold up through the continuous cycling, chemical exposure, and high water volumes of a busy commercial facility.

Car Wash Chemical Delivery Lines Corroding Under Continuous Detergent and Acid Chemistry Exposure

The pain: Car wash chemical delivery systems cycle detergents, acidic tire and wheel cleaners, alkaline degreasers, and wax and rinse aid concentrates through the same piping and valve infrastructure continuously. Metal fittings and valves in chemical delivery lines corrode under this chemical cycling, creating leaks in the equipment room that foul the facility, damage electrical components, and require service calls during operating hours.
The Alsco Advantage: PVC and CPVC thermoplastic ball valves, fittings, and piping in car wash chemical delivery lines handle the full range of car wash cleaning chemistry, alkaline detergents, acidic wheel and tire cleaners, and wax and rinse aid concentrates, without the corrosion that attacks metal components in continuous chemical cycling service. True-union designs allow in-line valve replacement without cutting pipe, keeping equipment room maintenance quick and non-disruptive to wash bay operations.

Relevant Products: Actuated Ball ValvesActuated Butterfly ValvesActuated Diaphragm ValvesFast Packs Actuated Valve PackagesSolenoid Valves

Car Wash Water Recirculation System Piping Corroding and Developing Leaks

The pain: High-volume water recirculation systems in modern water-efficient car washes cycle large volumes of wash water, containing suspended solids, detergent residuals, and elevated TDS, through filtration and reclaim infrastructure continuously. Metal piping in the reclaim system corrodes from the chemistry of recycled wash water, creating leaks below grade or in congested equipment rooms that are expensive to access and repair.
The Alsco Advantage: PVC Schedule 40 and 80 pipe and Spears fittings in the water recirculation and reclaim plumbing provide corrosion-immune infrastructure that handles recycled wash water chemistry without the internal corrosion that degrades metal pipe. Smooth thermoplastic interiors resist the biofilm and scale adhesion that increases maintenance frequency in reclaim systems, and properly solvent-welded joints with Weld-On cement and primer create permanent, leak-free connections that hold through years of continuous high-volume cycling.

Chemical Concentrate Transfer from Drums and Totes in the Equipment Room

The pain: Car wash chemical concentrates, detergent, tire cleaner, wax concentrate, and rinse aid, arrive in drums and totes that require transfer to day tanks and mixing vessels in equipment rooms where spills on the floor create both a slip hazard and a housekeeping problem. Manual tipping and pouring of concentrated chemical containers is the kind of routine task that creates unnecessary spill and exposure risk in an enclosed facility space.
The Alsco Advantage: Polypropylene drum pumps with chemical-resistant tubing and cam and groove couplings allow controlled chemical concentrate transfer from bulk containers to day tanks without manual lifting or pouring. The complete transfer path in chemical-compatible materials keeps chemical handling contained, efficient, and off the equipment room floor, reducing both the housekeeping burden and the spill risk that manual chemical handling creates in high-traffic facility areas.

JOINING MATERIALS & RIG ACCESSORIES
The Materials That Hold Every Connection Together

A soft wash rig or car wash facility plumbing system is only as reliable as its weakest joint. Solvent cement, primer, thread sealers, and gasket materials used in chemical-service applications need to be correct for the pipe material, the fitting schedule, and the chemistry in the line, because a failed joint in a bleach delivery system or a car wash chemical feed line is a leak nobody can afford.

Incorrect Solvent Cement or Primer Causing Joint Failures in Chemical Service Lines

The pain: Using a fast-set, light-bodied cement on a Schedule 80 fitting, skipping primer on a CPVC joint, or applying a cement not rated for the chemical service creates joints that pass visual inspection but fail under pressure or chemical exposure. A failed joint on a soft wash rig's chemical delivery system in the field, or in a car wash equipment room, is a bleach release in a place nobody wants it.
The Alsco Advantage: Weld-On solvent cements and P-70 primer in the formulations matched to PVC and CPVC pipe size, schedule, and chemical service ensure that every joint is made correctly, with the body weight, set time, and chemical resistance appropriate for the application. Our team can identify the correct Weld-On product for your specific pipe size and material before the first joint is made, eliminating the guesswork that produces field failures on chemical system plumbing.

Pressure Gauges Failing in Chemical Service Applications

The pain: Standard Bourdon-tube gauges with brass internals corrode and fail in sodium hypochlorite, acidic cleaning solution, and detergent service, reading inaccurately or stopping reading entirely. A pressure gauge that doesn't work removes a critical diagnostic tool from a chemical delivery system and from a car wash equipment room where pump performance and line pressure are both operational variables that matter.
The Alsco Advantage: Glycerin-filled pressure gauges with stainless steel and corrosion-resistant wetted parts maintain accurate, reliable pressure indication in the chemical service conditions that destroy standard gauges. Available in pressure ranges matched to soft wash delivery systems and car wash facility plumbing, they provide the diagnostic visibility that working gauges deliver, in the chemical environments where standard gauges fail.

Pressure Washing & Soft Washing FAQs

Q: What is the advantage of thermoplastic valves and piping over metal in industrial utility and process applications?
A: In industrial applications where the fluid being handled is corrosive, treated water, acidic process streams, caustic cleaning chemistry, cooling tower biocides, thermoplastic valves and piping offer three practical advantages over metal. First, they are chemically inert to the corrosive conditions that cause metal valves to corrode, seize, and fail, eliminating the replacement cycle that metal components generate in corrosive service. Second, they introduce no metallic corrosion products into the fluid stream, which matters in process water and cooling systems where particulate causes downstream equipment wear. Third, their service life in corrosive industrial applications dramatically exceeds that of metal alternatives, reducing total maintenance cost and system lifecycle cost even when the initial material cost is higher.

Q: When should I specify PVC versus CPVC for an industrial piping application?
A: The primary deciding factor is operating temperature. PVC is appropriate for industrial utility and process applications up to approximately 140°F at rated pressure. CPVC extends the usable temperature range to approximately 200°F and offers broader chemical resistance, making it the correct specification for hot water utility systems, industrial processes with elevated operating temperatures, and any service where conditions approach or exceed PVC's temperature rating. For chemical service, CPVC also offers improved resistance to certain caustics and oxidizing compounds that can attack standard PVC. Our team can help verify the correct material for your specific service conditions before you specify components.

Q: Do you carry strut channel and pipe clamps for industrial piping support applications?
A: Yes. We stock both steel and fiberglass reinforced plastic strut channel, along with a full range of pipe clamps, cushion clamps, two-hole clamps, clevis hangers, and beam clamps, for industrial piping support applications. For chemical handling areas, wet environments, and anywhere metal support hardware is subject to corrosion, fiberglass strut channel and fiberglass pipe clamps provide a corrosion-immune support system that matches the service life of the thermoplastic piping it supports. For general industrial and dry environments, steel strut in the appropriate finish covers most pipe support requirements. Thermoplastic pipe requires closer support spacing than metal pipe, and our team can advise on correct support intervals for PVC and CPVC systems to prevent the thermal stress joint failures that under-supported thermoplastic pipe produces over time.

Q: What actuated valve types are available for industrial process automation applications?
A: Alsco stocks both thermoplastic actuated valve packages for corrosive fluid service and metal-body actuated packages for general industrial process control. Asahi Smart Pack actuated valve packages in PVC and CPVC are factory-assembled with electric or pneumatic actuators for corrosive fluid service. Bonomi actuated packages on stainless steel and carbon steel valve bodies cover the full range of general industrial process control requirements, from simple on/off electric actuation to spring-return fail-safe pneumatic configurations for safety shutdown applications. Explosion-proof actuator options are available for classified hazardous locations. Both product lines ship factory-assembled and ready to commission.

Q: How do GF Signet flow sensors install in existing industrial piping systems?
A: GF Signet paddlewheel flow sensors install through a drilled and tapped fitting, a tee or saddle, in the existing pipe, requiring no pipe cutting and no system shutdown for installation in most configurations. GF Signet also offers ultrasonic clamp-on flow meters for non-invasive flow measurement on existing piping where process isolation is not practical. Both sensor types output 4-20mA or pulse signals for integration with plant PLCs, SCADA systems, and data historians, and both are available in plastic sensor body configurations compatible with PVC and CPVC industrial piping systems.

Q: What chemical metering pump is appropriate for industrial pH adjustment and chemical dosing?
A: For pH adjustment chemistry, acids and caustics, Blue-White peristaltic metering pumps are the preferred specification because no internal valves or seals contact the chemical, making them inherently resistant to the corrosive chemistry they're dosing. For scale and corrosion inhibitor programs and biocide dosing, Blue-White diaphragm metering pumps are appropriate for most industrial cooling water and process water treatment applications. Both types deliver precise, repeatable dosing rates that manual addition cannot match, and both are available in flow ranges matched to the full spectrum of industrial chemical treatment applications.

Q: Do you stock products for industrial plant MRO programs, not just project purchases?
A: Yes, MRO support is a core part of what we do for industrial customers. We maintain deep inventory on thermoplastic valves, PVC and CPVC fittings, tubing, instrumentation, pipe support systems, strut channel, pipe clamps, and joining materials that industrial maintenance teams need for both planned and unplanned repairs, in the specific brands and configurations that plants already have installed. No minimum order, same-day shipping on in-stock orders placed by 2PM EST, and a team that understands why material specification matters in the repair you're making.
