The H2FLOW CONTROLS fv-6 is a combination flow meter and check valve designed for plumbing systems where both flow measurement and backflow prevention are required in a single inline unit. The fv-6 integrates a visual flow indicator with a check valve function, allowing technicians to confirm flow rate and direction at a glance while preventing reverse flow. It includes a 6-inch tee fitting for direct integration into standard plumbing lines. This unit is installed by licensed plumbers and pool service professionals in applications that demand reliable flow monitoring without adding multiple components to the system.
The fv-6 is suited for residential and light commercial plumbing installations, including pool and spa circulation systems where flow confirmation is critical to equipment protection. The integrated tee design simplifies installation by reducing the number of fittings required at the service point. Its inline configuration makes it appropriate for pump discharge lines and filter system plumbing where consistent flow verification is part of standard maintenance practice.
Designed as an OEM-style inline replacement for plumbing flow meter and check valve assemblies in residential and light commercial plumbing systems. Specific compatible models or superseded part numbers were not provided in available product data.
Installation should be performed by a licensed plumber or qualified pool service technician in accordance with applicable plumbing codes such as the IPC. Shut off the water supply and depressurize the line before removing any existing fittings or valves. Ensure flow direction arrows on the body are aligned with system flow direction before securing connections. Do not overtighten threaded or slip fittings, as this may damage the valve body or visual indicator assembly.
