Product details

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.

Questions and answers

What people ask about this product, answered by our pool techs.

What does a FlowVis retrofit do?
It converts an existing Jandy check valve body into a FlowVis flow meter, so you get a GPM reading on the pad without cutting in a new fitting.
Which Jandy valve body does this fit?
The Jandy 2 in. by 2-1/2 in. check valve body. H2Flow makes a separate retrofit model for 1.5 in. Jandy bodies.
Does it include the valve body?
No. This is the retrofit for a valve body you already have installed. If you need the complete assembly, order the Jandy 2 in. / 2-1/2 in. check valve as well.
Why would I want a flow reading?
Flow in GPM tells you whether a variable speed pump is running fast enough for the heater or chlorinator, and whether a dirty filter is choking the system. It is the number the rest of the pad depends on.
