Monument 1515U Water Flow Weir Gauge MON1515

The Monument 1515U Water Flow Weir Gauge is a compact device designed to measure water flow rates in plumbing systems. It helps determine whether sufficient flow is available in a building before installing appliances such as washing machines, boilers, or showers, and it can assist in diagnosing whether a combi boiler or water heater may require descaling. Constructed from durable plastic with a stainless steel mesh strainer to reduce turbulence, the gauge features a dual scale for easy reading in both litres per minute and gallons per minute. Installation is inline with the water supply line, enabling accurate flow readings and simple verification of acceptable flow before equipment connection.
