HIGH-VOLUME WATER CIRCULATION
Built for the Flow Rates That Keep Attractions Running

A wave pool, lazy river, or competition pool doesn't just circulate water, it circulates hundreds of thousands of gallons continuously, every hour the facility is open. The valves, fittings, and piping at the heart of those systems need to handle high flow rates, aggressive sanitizing chemistry, and constant operational cycling without fatigue or failure.

Valves That Corrode, Seize, and Fail Under Continuous Chemical Exposure

The pain: Commercial aquatic systems run sanitizing chemicals, chlorine, sodium hypochlorite, CO2, muriatic acid, through their circulation infrastructure every hour of every operating day. Metal valves corrode in this environment, eventually seizing, leaking, and failing at the worst possible times, mid-season, mid-weekend, mid-capacity.
The Alsco Advantage: Hayward and Asahi thermoplastic ball and butterfly valves are chemically inert to the full range of pool sanitizers and pH adjustment chemicals. With no metal in the flow path, there's nothing to corrode, no operator mechanism to seize, and no corrosion byproducts entering the water guests are swimming in. They deliver years of maintenance-free service where metal alternatives require constant attention.
Relevant Products: Ball Valves • Butterfly Valves

High-Flow Demand Exposing Undersized or Restrictive Components

The pain: Attraction pools, wave systems, and lazy rivers require massive, sustained flow rates. Valves and fittings that introduce flow restriction create pressure imbalances, reduce attraction performance, and force circulation pumps to work harder, increasing energy costs and mechanical wear across the system.
The Alsco Advantage: Full-port thermoplastic ball and butterfly valves from Hayward and Asahi are engineered for large-diameter, high-volume flow with minimal pressure drop. Combined with properly sized PVC and CPVC piping and fittings, these components let your circulation system deliver what it was designed to, without throttling performance at the valve.

Valve or Piping Failures Forcing Unplanned Attraction Shutdowns

The pain: A failed isolation valve or a leaking fitting on a major attraction doesn't just create a maintenance problem, it pulls a revenue-generating attraction offline during operating hours. In peak season, every hour of unplanned downtime is a measurable financial loss and a guest experience failure.
The Alsco Advantage: True-union thermoplastic valve designs allow in-line component replacement without cutting pipe or taking the surrounding system offline. With same-day shipping on in-stock replacement parts, a failed component identified in the morning can be replaced and back in service the same day, not next week.
Relevant Products: Ball Valves • Flexible Couplings • Pipe Fittings

WATER TREATMENT & CHEMICAL DOSING
Precise Chemistry Keeps Guests Safe and Regulators Satisfied

Public health departments don't grade on a curve. Commercial aquatic facilities operate under strict chemical balance requirements, free chlorine levels, pH ranges, combined chlorine limits and the metering equipment that delivers those chemicals must be accurate, reliable, and verifiable. Getting it wrong means health code violations, facility closures, and guest safety events.

Inaccurate Chemical Dosing Creating Compliance Risk

The pain: Overdosing sanitizers wastes expensive chemicals, irritates guests, and can trigger health department complaints. Underdosing creates pathogen risk and compliance violations. Manual chemical addition is inconsistent by nature and in a facility circulating hundreds of thousands of gallons, the margin for error is narrow.
The Alsco Advantage: The Lutz MAGDOS Solenoid Diaphragm Dosing Pump delivers precise, electronically controlled chemical feed at repeatable rates across the full operating range of commercial aquatic facilities, replacing the variability of manual chemical addition with a documented, calibrated dosing system. Chemical-resistant wetted parts handle sodium hypochlorite, pH adjustment chemistry, and the full range of pool treatment chemicals without the degradation that affects incorrectly specified pump materials in continuous aquatic chemical service.
Relevant Products: Diaphragm Dosing Pumps • Chemical Tubing

No Flow Verification Tied to Chemical Feed Systems

The pain: A chemical metering pump that's running but not actually delivering to the circulation line, due to a vapor lock, a blocked injection point, or a failed check valve, can go undetected for an entire operating session. The result: under-treated water with guests in it, and no documented verification for health inspectors.
The Alsco Advantage: Blue-White's F-300 and DIGI-METER F-1000 flow meters provide verified, real-time flow confirmation on chemical feed lines and main circulation loops, giving operators documented proof that treatment chemicals are reaching the water and that flow rates meet health department requirements. The F-1000 specifically supports regulatory compliance documentation in commercial pool applications.
Relevant Products: Flow Meters • Flow Sensors • Instrumentation

CO2 and pH Systems Incompatible with Standard Plumbing Materials

The pain: CO2-based pH adjustment systems, increasingly preferred over muriatic acid for guest safety and handling simplicity, require piping and fitting materials specifically compatible with carbonic acid. Using the wrong materials results in accelerated degradation of seals, fittings, and injection points, creating maintenance headaches and potential leaks.
The Alsco Advantage: We stock the CPVC fittings, chemical-resistant tubing, and compatible injection point components appropriate for CO2 feed systems, as well as traditional acid-based pH adjustment lines. Our team can help you match the right materials to your specific treatment chemistry before a mismatch becomes a service call.
Relevant Products: CPVC Schedule 80 Fittings • Chemical-Resistant Tubing • Diaphragm Pumps

FILTRATION SYSTEMS
Clean Water at Commercial Scale Requires Commercial-Grade Filtration

A high-bather-load commercial pool or water park attraction generates a filtration demand that residential or light commercial equipment simply can't meet. The filtration systems that protect guest health and maintain water clarity at commercial scale need to be sized for the load, built for continuous operation, and straightforward to backwash and maintain without pulling trained staff off the floor.

Undersized or Inadequate Filtration Compromising Water Clarity and Health Standards

The pain: High bather loads in wave pools, competition pools, and lazy rivers introduce bather waste, sunscreen, and organic contaminants at a rate that overwhelms undersized filtration. Cloudy water is a health code violation waiting to happen and a guest experience failure that spreads on social media faster than any marketing campaign.
The Alsco Advantage: Hayward's HCF Series commercial sand filters are purpose-built for the sustained demands of water parks, aquatic life support, and high-bather-load facilities. Multi-diffuser distribution heads, oversized laterals, and robust PVC internals deliver superior filtration efficiency and extended filter cycles, keeping water clear under peak load conditions without constant backwashing.
Relevant Products: Filters & Accessories • Sight Glasses • Multiport Valves

Debris and Particulate Damaging Pumps and Clogging Attraction Nozzles

The pain: Outdoor water attractions introduce leaves, sand, and environmental debris into circulation systems continuously. Without adequate straining upstream of pumps and feature nozzles, particulate causes pump seal wear, clogs attraction jets, and reduces water feature performance, requiring frequent, disruptive maintenance.
The Alsco Advantage: Hayward simplex and duplex basket strainers installed upstream of pumps and feature nozzles intercept debris before it reaches sensitive equipment. Available in PVC, CPVC, and glass-filled polypropylene for chemical compatibility across treatment regimens, they protect your mechanical systems and keep attraction performance consistent throughout the operating day.
Relevant Products: Line Strainers • Sight Glasses • Clear PVC Pipe • Clear PVC Pipe Fittings

WATER FEATURES, FOUNTAINS & THEMED ATTRACTIONS
Where Guest Experience Meets Engineering Precision

Decorative fountains, interactive splash features, themed water effects, and pressurized water jets are as much guest experience as they are plumbing systems. The components that power them need to perform reliably on cue, handle the pressure demands of high-effect nozzles, and do it all in outdoor environments subject to UV, temperature swings, and aggressive sanitizing chemistry.

Feature Nozzles and Jets Losing Pressure Due to Failing Flow Control

The pain: A splash pad or themed fountain that operates at inconsistent pressure, some jets firing strong, others trickling, doesn't just look bad. It signals to guests that the facility is poorly maintained, and it signals to operators that something in the flow control system is failing. Corroded or undersized valves upstream of feature zones are a common culprit.
The Alsco Advantage: Thermoplastic ball valves with full-port bores and bubble-tight shutoff allow precise zone isolation and flow adjustment for individual feature circuits so each nozzle bank performs exactly as designed, and individual zones can be isolated for service without taking down the entire attraction.
Relevant Products: Ball Valves • Actuated Valves • Multiport Valves

Manual Valve Operation Making Feature Sequencing Slow and Labor-Intensive

The pain: Water attractions and fountain features that rely on manual valve operation for sequencing, show timing, or zone switching require staff to be in the mechanical room during attraction operation, an inefficient use of labor that also limits how dynamically the feature can be programmed or adjusted.
The Alsco Advantage: Hayward and Asahi electric and pneumatic actuated valves integrate with automation controllers to enable precise, repeatable feature sequencing, timed zone switching, and remote isolation without staff in the mechanical room. From simple on/off control to proportional flow modulation for dynamic effects, actuated thermoplastic valves bring modern control capability to water feature systems of any complexity.
Relevant Products: Actuated Ball Valves • Actuated Butterfly Valves • Actuated Diaphragm Valves • Solenoid Valves

Outdoor Piping and Components Degrading from UV and Temperature Cycling

The pain: Outdoor water features and splash pad infrastructure are exposed to direct sunlight, seasonal temperature swings, and freeze-thaw cycles that degrade materials not specifically rated for outdoor service. Premature fitting failures, cracked pipe, and failing valve bodies on outdoor features create both safety risks and unplanned maintenance costs.
The Alsco Advantage: Schedule 40 and 80 PVC and CPVC pipe and fittings from Spears are formulated for long service life in outdoor water contact applications. For above-grade runs with direct UV exposure, our team can help identify the right insulation, shielding, or material upgrade, such as CPVC or glass-reinforced polypropylene to match your installation environment.

Commercial Aquatic Facility FAQs

Q: Why are thermoplastic valves preferred over metal valves in commercial pool and water park systems?
A: Commercial pool and water park systems circulate aggressive sanitizing chemicals, chlorine, sodium hypochlorite, muriatic acid, CO2, continuously through their piping infrastructure. Metal valves corrode in this environment, eventually seizing and failing, and corrosion byproducts can introduce unwanted metals into pool water. Thermoplastic valves from Hayward and Asahi are chemically inert to the full range of pool treatment chemicals, require no corrosion maintenance, and outlast metal alternatives by years in aquatic service.

Q: What is the difference between a simplex and duplex basket strainer for commercial pool applications?
A: A simplex basket strainer has a single basket and requires flow to be shut off to clean or replace the basket which means briefly taking that circuit offline. A duplex basket strainer has two baskets in parallel, allowing one basket to be cleaned while the other remains in service, so filtration never has to stop. For high-bather-load or continuous-operation attractions, duplex strainers are the preferred choice upstream of critical pumps and attraction systems.

Q: How does a Blue-White chemical metering pump support health department compliance?
A: Blue-White peristaltic and diaphragm metering pumps deliver precise, repeatable chemical feed at documented rates, replacing the variability of manual chemical addition with a verifiable, calibrated system. When paired with a Blue-White DIGI-METER flow meter on the chemical feed line, operators can document actual chemical delivery rates for health inspector review, supporting the continuous chemical balance records many jurisdictions require of commercial aquatic facilities.

Q: What size sand filters are available for water park or large commercial pool applications?
A: Hayward's HCF Series commercial sand filters are available in molded styles from 30" to 36" and bobbin-wound styles from 42" to 63", covering the full range of commercial aquatic demands from large community pools to major water park attractions. For sizing guidance based on your facility's bather load and flow rate requirements, our sales team can assist with product selection.

Q: Can actuated valves be used for water feature and fountain sequencing control?
A: Yes. Hayward and Asahi electric and pneumatic actuated ball and butterfly valves integrate with standard automation and programmable logic controllers to enable timed zone sequencing, show programming, and remote isolation for water features and fountain attractions. Our team can help specify the appropriate actuator type, electric on/off, proportional, or pneumatic, based on your control system and cycle requirements.

Q: Do you stock products for CO2-based pH adjustment systems in commercial pools?
A: Yes. CO2 pH adjustment systems require piping and injection components rated for carbonic acid service. We stock compatible CPVC fittings, chemical-resistant tubing, and injection point accessories appropriate for CO2 feed lines, as well as Blue-White metering pumps suitable for CO2 applications. Contact our team to confirm material compatibility for your specific system design before ordering.

Q: Do you offer same-day shipping on replacement parts for commercial aquatic systems?
A: Yes. All in-stock orders placed by 2PM EST, Monday through Friday, ship the same business day from our Atlanta-area warehouse. We maintain stock on Hayward and Asahi thermoplastic valves, Blue-White flow meters, Lutz dosing pumps, and PVC and CPVC fittings, so when an attraction goes down, you're not waiting a week for a replacement part.
