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.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFit\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThis model fits the Jandy 2 in. by 2-1\/2 in. check valve body.
