hi all, thinking ahead to if i successfully change over the old valves to the new ones. is there a way i can slowly release the water when checking for leaks? for example when i did some work on my shower. i would turn off at the main. when testing, i only add one turn to allow some water to come through. if it leaks, it will be at low pressure and enough for me to just switch off. at mine i don't have a tank in the loft. in this case i do.

thanks

If the pump is on the ground floor open any radiator vent that is just above it, start filling the system, stop filling as soon as water comes from the vent and inspect the pump/valves for leaks. If the pump is located higher up then you have to fill to a higher level.
