Brass Victac Geyser Nrv Non Return Valve 1/2" Inch Bsp 0.8 Mpa Pressure Safety Water Heater Safety Relief Valve Pack Of 1

V good product

This is not an NRV, actually it is good for nothing. Water is coming out in opposite direction of the direction marking. I the only reason for not returning this because of effort to remove it from gyser.

Good

Received as shown except the red lever was black in received product.Pros:1) Comes with two quality rubber washers2) Worked fine and stopped my gas geyser unnecessarily getting activated momentarily due to reverse water flow when other taps were used on the same water circuitCons:1) The pressure safety valve outlet was leaking after installation and at a particular position of the lever it stopped leaking. If lever is not operated manually, then there should not be any water leak2) The rubber washers that came with unit could not stop water leak at threads on female thread side and had to finally also use teflon tape to stop leak. This happens as the washer sits on threads and does not seal inside walls because of this. I think the washers were provided by vendor and not by design. The washer is expected to be seated in dedicated postion inside the female thread side and since it is not present, the water leaks from walls of threads and washer is not able to do it's job well

Working properly

Nice quality
