I've just fitted a 50 gallon cold water tank in preparation for a fitting a shower pump.
When the tank is filling at full flow there's quite a bit of noise being transmitted back down the cold water pipe and into the bathroom below. The noise goes as soon as the float rises and starts to reduce the flow. The noise wasn't there when the old tank was in use.
The cold water pipework hasn't changed much, the only difference being the new float valve and a 90 degree isolation valve elbow fitted to the ball valve.
The noise is definitely coming from either the float valve or the 90 degree isolating elbow (which is fully open) but can anyone give me a pointer on which is likely to be the culprit.
I can replace the isolating elbow with a standard elbow fairly easily, but wondered if anyone had experience this before and as to whether its likely to be the elbow or the float valve itself?
The float valve came with the 50 gallon water tank kit that i bought from screw fix, as did the isolating elbow , so no idea of brand i'm afraid but i've linked to the kit below:
