It combines a clear, easy-to-read GPM (gallons-per-minute) scale with a built-in check valve, letting you measure real system flow while also preventing reverse flow in the return line.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eIntegrated flow meter and check valve in one compact body.\u003c\/li\u003e\n\u003cli\u003eDesigned for 2\" PVC Schedule 40 pipe installations.\u003c\/li\u003e\n\u003cli\u003eDirect GPM scale for quick, accurate flow verification.\u003c\/li\u003e\n\u003cli\u003eClear housing allows visual confirmation of flapper\/check operation and water movement.\u003c\/li\u003e\n\u003cli\u003eHelps optimize pump speed settings, heater\/salt-system flow requirements, and overall efficiency.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel \/ Part Number:\u003c\/strong\u003e FV-2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipe Size:\u003c\/strong\u003e 2\" Schedule 40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow Scale:\u003c\/strong\u003e GPM (gallons per minute)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eValve Type:\u003c\/strong\u003e Inline check valve with flow measurement\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Pool\/spa return plumbing, equipment pad flow verification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eInstallation \u0026amp; Compatibility Notes\u003c\/h2\u003e\n\u003cp\u003eInstall the FV-2 in-line on a straight section of 2\" return plumbing after the filter (and typically after the heater) where consistent flow measurement is desired. Follow the flow-direction arrow on the body to ensure correct check-valve operation. Use proper PVC primer and cement, and allow full cure time before pressurizing. Once running, read the GPM indicator with the pump operating at the intended speed.\u003c\/p\u003e\n\u003ch2\u003eMaintenance Tips\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003ePeriodically inspect the clear body for debris buildup that could affect the check flapper or the flow reading.\u003c\/li\u003e\n\u003cli\u003eIf flow readings drift, verify there are no upstream restrictions (dirty filter, closed valves, clogged baskets).\u003c\/li\u003e\n\u003cli\u003eDuring seasonal service, confirm the check valve opens smoothly and closes fully when the pump stops.\u003c\/li\u003e\n\u003cli\u003eWinterize by draining the line as you would any inline fitting to prevent freeze damage.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWhy Choose the FV-2?\u003c\/h2\u003e\n\u003cp\u003eThe FV-2 is a practical upgrade for anyone who wants true system flow data without adding extra fittings.
