Hot Water pipes "ringing"

[efiste2]

When we start to run the hot water tap in our kitchen the hot water pipes start to "ring" and reverberate through the system , in a similar way the toilet water feed pipe sounded when the float valve needed replacing/fixing......the only thing I can think off in my limited knowledge is that its the float valve in the header tank above the HW cylinder......Have oany of you knowledgable chaps got any suggestions

Poss a fault jumper tap insert on the tap.
Is it only the kitchen tap that does it ?
Can you hold or push down on the tap when the noise starts and does it stop the noise ?

yes its only the kitchen tap, so I guess that rules out the float valve in the header tank (should have spotted that ) The kitchen tap is a basic cheapo mixer tap which really needs repacing as it leaks when turned.....I have replaced the o rings on it.....

You can check the float valve by isolating it or hold it closed while you try the tap again, if it still does it with the float valve not filling then the answer is your tap insert.

I have the same problem. I recently came back from a 2 week vacation and noticed the water pressure in the kitchen sink was pretty low. I had unscrewed the faucet head and cleaned out the gasket/filter earlier and it helped. This time it didn't seem to help. Also as the water heats up there begins to be a ringing sound. If I switch over to cold, the ringing goes away.

What is the float valve?

What is the float valve?

Something like this in the cold water storage cistern or a toilet cistern

Allows the automatic filling of the cistern.
