H2Flow Controls FlowVis Retrofit for Jandy 2 in. by 2-1/2 in. Check Valve Body

The H2Flow Controls FV-J-R is a FlowVis retrofit for Jandy 2 in. by 2-1/2 in. check valve bodies. It converts the check valve you already have on the pad into a FlowVis flow meter with a GPM scale, so you can read actual flow without cutting a new fitting into the plumbing.

Fit

This model fits the Jandy 2 in. by 2-1/2 in. check valve body. H2Flow makes a separate retrofit for 1.5 in. Jandy bodies, so match the model to your valve size. The valve body itself is not included.

Why measure flow

A GPM reading shows whether a variable speed pump is turning fast enough for the heater and chlorinator, and whether a loaded filter is restricting the system. It replaces guesswork with a number.
