Above-Ground Pool Valves


Above-Ground Pool Valves, many people don't even think of these, until theirs is broken or leaking. Then what type and brand do you need? We at 1800Pools can help you decide. As we have been in the swimming pool industry for 40 years, we have the knowledge and expertise to guide you.

Can I replace my slide valve with a multi-port valve and should I? These are the questions that we can answer.

Other valves in your swimming pool filtering system are pool diverter valves and pool check valves . Many of you have these and may not know what they are. These are also important parts to your swimming pool and may need to be serviced or replaced.

Let us help you to make the right decision if these items need to be serviced.

Our Hi-Flow backwash valve is designed for maximum performance and working pressures. It features the same quality and reliability you've come to know and expect from Pentair. It's pre-plumbed for easy installation in side-mounted sand or D.E. (diatomaceous earth) filter applications.

Above-Ground Pool Multi-port Valves


Key features include:
Solid, injection-molded PVC housing permits leak-free solvent welds to PVC piping.

Large, reinforced one-piece handle for years of trouble-free operation.

High efficiency center intake diverter is made of heavy-duty, glass-filled Noryl® thermoplastic for strength and heat resistance.



Full-feature valve offersmaximum control


The Hi-Flow valve features full six-position, positive lock operation plus a special winterizing position providing access to a full range of filtration system capabilities.The Hi-Flow valve provides precise control of pool filter functions. And as with all Pentair valves, the Hi-Flow valve is designed to perform flawlessly for years to come.

Other features include:
Full two-inch inlet and outlet ports for unrestricted water flow during all cycles.

Clearly and permanently marked ports for ease of plumbing with either sand or D.E. (diatomaceous earth) filters.

Engineered to accommodate up to 125 gpm flow rates with proper system plumbing and compatible pump/filter combinations.

Valve controls filter's function


Sand filters are controlled with eitherof two types of valves:

Slide-valve Has just twopositions, and is always sidemounted(photo at left).

Multi-valve Has multiplepositions, and can be top orside-mounted (photo below).

With their many settings, multi-valves can raise questions among technicians as to their proper function. Following are the seven positions ofHayward's popular Vari-Flow multi-valve, and theeffect each of those seven positions has on the sand inside the filter.

FILTER mode The valve directs water to the top of the filter, where the water compresses and flattens down the sand as it makes its waythrough to the bottom laterals.

BACKWASH mode The valve directs water tocome out the bottom laterals, reversing the flowof water through the tank. This causes the sandto separate and lift about 7 above its normallevel, thereby releasing the trapped debris intothe water and allowing it to exit the filterthrough the waste line.

RINSE mode Water is directed to (enters) thetop of the tank (just like filter mode) but exitsthrough the waste line (instead of the laterals).This re-seats the sand after backwashing, andminimizes particulate blow back once normalfiltration is resumed.

RECIRCULATE mode Water is directed through the valve only, not the filter. This is a position to use during some pool cleanups and chemical treatments where you don't want the watercontaminating the sand an example would bewhen using a drop and floc product in thepool.

WASTE mode This position bypasses thefilter and sends all water out the waste line agreat setting for vacuuming pools after an algaetreatment, for new sand addition, and for newfilter start-ups.

Lube-free 2- and 3-Way Valves and Check Valves


Our lube-free valves have excellent flow characteristics and are manufactured to strict quality standards. And as the name says, they never require lubrication. Constructed of durable CPVC or PVC, they provide a lifetime of superior performance at a great price. All Pentair valves are easily installed and simple to use. And when paired with Pentair valve actuators, they're the perfect solution for fullyautomated operation.

Standard 2-way and 3-way Valves
Ideal for diverting, shut-off, or mixing applications. The Teflon composite diverter seal requires no lubrication. Field-adjustable stops ensure precise positioning while simplifying use, and the extra-wide diverter offers superiorsealing when used with valve actuators.
Dual O-rings, separated by a hard spacer, provide optimum shaft sealing for dependability.
Body available in high-temperature CPVC* or low-temperature PVC.
Available in two popular sizes: 1?" x 2" and 2" x 2?".
Maximum body pressure 150 psi, maximum sealing pressure 35 psi.
Lifetime seal warranty.



Check Valves
Our beefier, dual-swivel-point flapper is self-centering for superior sealing, and requires only 15 inches of water column. The low-tension spring provides maximum flow.Service is simple, since parts can be replaced without cuttingthe valve out of the plumbing.

Clear polycarbonate cover allows easy inspection.
Cover is easily removed for cleaning.
Cover can be flipped 180 degrees tochange flow direction.
High-temperature CPVC body.
Use with 2" pipe or 2?" fittings.

Pentair valves offer dependable, lubrication-free performance for less. Engineered for long life, they outperform other manufacturers' higher priced valves. Ask your sales representative for pricing.
*Use CPVC valves where air temperatures can reach 105?F.
