Valves & Auto-Fills

At Webb's we offer a wide variety of valves - including ball-valves, check valves, auto fill valves and more. Check valves prevent water backflow when the pump is not operating. Fill valves automatically add water to features and ponds when needed.

These check valve assemblies are used inside Pro-Series skimmers to bring the flow of water from the pump up to the outlet hole in the back wall of the skimmer. In an ideal world all pumps would have their outlet at the same height but that is not the case so various height assemblies are needed. Each assembly includes a check valve which keeps the plumbing line full of water even when the pump is off. Please see chart below for the correct pump/skimmer check valve. 

CVA20TH is for TH series pumps in PSA5000, PSA7000, PS1V or PS1FB skimmers and JAFM, JAFL or PV60E vaults

FlowVis is a revolutionary, patented solution for accurate and reliable flow and velocity rate measurement in fresh water applications such as swimming pools, spas, fountains, water features, ponds, irrigation systems, ground water applications, well water and solar systems. As flow increases, the flapper moves forward toward its fully open position. The flapper’s angular position is directly related to the flow rate through the valve body/tee/pipe. A calibrated scale on the valve’s lid provides a highly accurate reading of the flow rate and velocity.

  • Ease of installation with zero to minimal straight pipe
  • Installation flexibility that allows orientation in any position, e.g., horizontal, vertical or even upside-down
  • Long life without sticking floats or paddle wheels
  • For use with external motor driven pumps only
