## Description

FVJ-RFVJ-R

Review: Works well - but overpriced - Expensive for a piece of plastic, but it does what it says, measures water flow. Perfect fit and replacement for my Jandy valve cover. Simple to install.
Review: Drop in for Jandy check valve - My Jandy check valve had checked out over a year ago and instead of replacing the check valve, I decided on this. It seems fairly accurate and let's me better calculate my necessary pump run time.
