Noise when i use Hot Water

Yus89

Hi,
Looking for some advice regarding some issues i have encountered with my cold water tank. Recently it was overflowing so i had the whole valve replaced, problem solved or so i thought. Gladly the overflow stopped but now whenever i switch the hot water on upstairs or downstairs it makes a noise, kind of like water rushing up pipes noise so after reading up on some forums i checked in the loft to see if the noise stopped if i lifted the ball valve up to stop any more water coming in to the tank whilst hot water is being used and it does stop making the noise. I am a total novice so wouldnt know what is happening. When i switched the stopc0ck back on after the float valve had been changed i did switch it on rather fast and maybe more turns than what i had done to close it.

Any advice would be much appreciated.

Thank you in advance for your help.

If I recall correctly, those fill valves tend to be rated for either high or low pressure. I wonder if the new valve has a low pressure insert, rather than a high pressure insert.


I'm sure someone with more experience will correct.

Hi, thanks for your reply, it was a type 1 valve (the bendy arm) that was fitted.
The noise seems to come when filling the cold water tank and will stop soon as valve closes.

You've got an old fashioned valve. Those were noisy. Live with it IIWY.
