Buying Guide

What should I consider when choosing a high flow relief valve?

  • Filter compatibility: Ensure the valve supports your specific filter models (CCP, FNS, Quad DE, Predator, Warrior, EasyClean, etc.).
  • Gauge type and placement: Decide between top-mount gauges or inline gauges, and whether you need a complete gauge kit included.
  • Material and durability: Brass variants offer durability in outdoor environments; plastic bodies may be lighter but equally capable for many setups.
  • Installation simplicity: Look for screw-in designs and kit-inclusive assemblies to minimize tools and time.
  • Pressure stability: A unit with a precise, easy-to-read gauge helps maintain optimal cleaning cycles and reduces backpressure risks.
  • Availability of accessories: O-rings, clips, teflon tape, and gauge plugs included in the kit save extra parts shopping.

Which features indicate a reliable high flow relief valve?

  • Clear, legible gauge with a defined pressure range.
  • Stable build to resist leaks and cracks under high water pressure.
  • Broad compatibility with common filter brands and model numbers.
  • Comprehensive installation hardware included.
  • Top-mount or inline configurations that fit your system layout.

How do I install a high flow relief valve?

  1. Turn off the pool pump and depressurize the system.
  2. Remove the old relief valve from the filter housing.
  3. Apply teflon tape to threaded ends and seat the new valve gasket or O-ring in place.
  4. Screw the valve into position firmly without over-tightening.
  5. Open the valve slowly and monitor for air release and any leaks.

What are common installation mistakes to avoid?

  • Using incompatible gauge types for your filter brand.
  • Over-tightening fittings, which can crack housings or strip threads.
  • Installing in the wrong orientation or without a proper O-ring seal.
