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.
Relevant Products: Ball Valves • Multiport Ball Valves • Specialty Valves
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.
Relevant Products: Ball Valves • PP Cam & Groove Couplings • Chemical Tubing • Check Valves • Line Strainers • Pressure Gauges • PVC Schedule 40 Fittings • PVC Schedule 80 Fittings • CPVC Schedule 80 Fittings
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.
Relevant Products: Line Strainers
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: Ball Valves • PVC Schedule 40 Fittings • CPVC Schedule 80 Fittings • Check 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 materials are compatible with sodium hypochlorite (bleach) in a soft wash system?
A: For components that contact sodium hypochlorite solution in a soft wash system, polypropylene is the preferred material for valves, cam and groove couplings, and fittings, it is highly resistant to bleach across the concentration range used in professional soft washing and resists the surface oxidation that attacks other materials. PVC is also broadly compatible at standard soft wash concentrations and is appropriate for many fittings and valves in bleach delivery systems. CPVC extends the service range for applications with higher temperatures or chemical concentrations. The materials to avoid in bleach contact service are brass, aluminum, and standard metals, which corrode rapidly under sodium hypochlorite exposure, and standard vinyl tubing, which hardens and cracks under sustained bleach exposure. Our team can verify material compatibility for any specific component and concentration before you order.
Q: What type of cam and groove coupling should I use on my soft wash rig for bleach connections?
A: Polypropylene cam and groove couplings are the correct specification for sodium hypochlorite connections on soft wash rigs. Polypropylene is fully chemically compatible with bleach at professional soft washing concentrations, resists the surface oxidation that attacks aluminum couplings, and provides the quick-connect chemical transfer that soft wash operations require. Standard aluminum cam and groove couplings, common in agricultural and industrial applications, corrode under direct sodium hypochlorite contact and should not be used in bleach service. EPDM gaskets are compatible with sodium hypochlorite for the cam and groove seal; FKM (Viton) gaskets are appropriate for applications with other chemical exposures. We stock polypropylene cam and groove in the sizes most commonly used in soft wash rig plumbing.
Q: Is there a minimum order to purchase from Alsco for pressure washing and soft washing components?
A: No. There is no minimum order quantity or dollar minimum. A single ball valve, a single cam and groove coupling, or a single section of chemical tubing ships the same day on the same terms as a larger production order. For pressure washing and soft washing contractors who need specific components to complete a rig repair or build, same-day shipping without a minimum order means you get what you need before the next job, not after it.
Q: What is the difference between chemical-resistant tubing and standard vinyl tubing for soft wash applications?
A: Standard clear vinyl tubing (PVC vinyl) hardens, becomes brittle, and cracks under sustained sodium hypochlorite exposure, particularly in the outdoor, UV-exposed conditions of soft wash equipment in active use. Chemical-resistant tubing formulated for bleach service maintains flexibility and integrity under the same conditions, resisting the hardening and cracking that makes standard vinyl tubing a seasonal replacement item on soft wash rigs. For the connections between chemical tanks, metering blocks, and pump inlets on a soft wash system, chemical-resistant tubing is the correct specification, the incremental cost difference is far smaller than the field failure cost of replacing cracked standard tubing mid-season.
Q: What Weld-On solvent cement should I use for PVC and CPVC plumbing in a chemical service application?
A: For PVC fittings and pipe in Schedule 40 soft wash and car wash plumbing, Weld-On 711 or 717 medium-bodied cements are appropriate for most connection sizes, used with P-70 purple primer. For Schedule 80 PVC and CPVC in larger sizes or chemical service applications requiring higher joint strength, heavier-bodied formulations with appropriate set times for the fitting size and ambient temperature are specified. The correct cement for any specific application depends on pipe material, fitting size and schedule, ambient temperature during installation, and chemical service requirements, our team can identify the right Weld-On product for your specific application before you start making joints.
Q: Do you stock drum pumps for transferring sodium hypochlorite and other cleaning chemicals?
A: Yes. We stock polypropylene drum pumps specifically compatible with sodium hypochlorite, alkaline detergent concentrates, acidic cleaners, and the range of chemical concentrates used in professional pressure washing and soft washing operations. Polypropylene wetted parts handle the chemical exposure that destroys standard pump materials in bleach and acid service. Paired with chemical-resistant tubing and polypropylene cam and groove couplings, they provide a complete, contained chemical transfer system from bulk storage containers to day tanks and rig tanks, without manual lifting, pouring, or the spill risk that goes with both.
Q: Do you offer same-day shipping on pressure washing and soft washing components?
A: Yes. All in-stock orders placed by 2PM EST Monday through Friday ship the same business day from our Atlanta-area warehouse via UPS and FedEx. We stock polypropylene and PVC ball valves, PP cam and groove couplings, chemical-resistant tubing, line strainers, pressure gauges, drum pumps, PVC and CPVC fittings, and Weld-On cements and primer, the components washing industry professionals most commonly need quickly. When a rig is down or a build is waiting on one component, same-day shipping means work resumes tomorrow.
