noisy pipes

[hendo127]

hi all as some of you may know ive just had a vaillent 824 fitted working fine thing is when ever i open any tap hot cold, kitchen and bathroom there is a knocking in the pipes. Even happens when toilet is flushed. It seems more pronounced when the hot tap is operated.

your help is much appriciated

Sounds like water slam,

Change the wash mac taps too integral none returns and check pipes where clipped down when new boiler was fitted

thing is it was the boiler was a 1 for 1 swap and it happens when i run the cold taps and thats a direct feed from the mains. any ideas

what do you mean wash mac taps?

 

[clf-gas]

Issolation valves to the washing machine.

 

[hendo127]

you think it could be that nothing has changed though its more of a creaking noise when the taps are turned on

 

[clf-gas]

Knocking or "creaking" is pipe movement

 

[hendo127]

what do you think it could be like i say nothing has changed apart from the boiler and the cold tap goes no where near the boiler?

 

[clf-gas]

Is the mains stop tap open more than it was before new install

 

[hendo127]

na i always have it fully open !!!

Then clutching at staws, ther is a dead leg on the water pipes somewhere that wasnt apparant with the old boiler.

I agree with craig on this. When the cold tap etc is turned on get someone to look at the display on the boiler. Does the tap symbol flash on for a couple of seconds.

If it does then a dead leg has been proved. If not keep looking.

my plumber suggested it may be the water inlet to the toilet can this be the case?

May need a PRV and or shock arrester.
