Possible "water hammering" in flat......

[Gilbo]

Hi All - I have a problem with rattling pipes when water is turned on in my flat.

• I'm top floor of a 3 storey development (c10 years old)
• Issue has only been prevalent in the last 8-10 weeks but has gotten gradually worse.
• The pipes rattle when water is turned on but appears to be concentrated in my main bathroom.
• Water is forced through my hot tap (mixer variety) in the main bathroom also (even in a closed position)
• By turning the hot tap on in the main bathroom, relieves the noise and vibration
• Noise is generated by washing machine being in use, flushing of toilet or by turning the taps on in the en suite and kitchen.
• The noise always centres in the main bathroom, regardless of where the originating water flow is generated.
• I've had the inner tap component replaced & new piping fitted to toilet, but noise still persists.

Any advice to eradicate greatly appreciated.

Are the pipes where the noise is occurring visible/accessible?

Where is your stopcock

Pipes are not visible unfortunately - they're behind the bathroom wall.

Where is your stopcock

Under the sink in the kitchen - I've reduced the water pressure to almost a trickle and it's still occurring.

Also, I should mention that in the majority of occasions, even just touching the hot tap, resolves the issue. Could the problem be with the mixer tap itself?

Could be the tap. Could also be another outlet. Toilet fillers are quite common at transferring noise down pipework

How have you reduced the pressure, closing down the stop tap doesnt reduce pressure, it restricts flow.

Got a thermostatic mixer shower?

This, and your report that the noise can be triggered in several ways, makes me suspect that some pipe(s) wasn't clipped securely and are gradually working loose.

How sure are you about the location of the pipes? Have you had a look under the bath?

Yep that's what I was thinking, just read the other posts, its a shame the pipes aren't accessible in the bathroom as would be a quick easy one to confirm other wise.

Is there a bath panel that can be removed to get to the pipes?

Are there no service valves near individual outlets so you can isolate one at a time and find the source of the noise by a process of elimination?
