Just turned my kitchen tap on and now my pipes are making a lot of noise. Sounds like a distant drilling, anyone know what it could be or how I fix it?
Thanks |  | | |  |

Possibly water hammer. Turn the tap on again, then off slowly. |  |

We get a loud noise in our pipes on occasions when the downstairs toilet is flushed.
Flushing it again sometimes solves it, but it sometimes comes back.
The things I have tried include turning off the mains stop cock, but turning it on not quite as much. This has worked in the past but sometimes it comes back.
I put it down to an airlock, but I am not sure if that is what it is. This suggests the answer to an airlock but I have never tried that.

Sounds like this could just be a worn diaphragm washer, quite an easy fix | | | |

Same issue - in block of flats where I live we have had issues for last few days - crap pressure and water stopping for a few hours before coming back again. | | | |

Thanks all. Turned off the water at the external stop cock and drained the system through the taps, flushed the toilets empty. Turned it back on filled the system back up and appears (for now at least) to have stopped the mind numbing vibrating noise. Perhaps was air in the system?
The biggest win in doing this is I’ve seen some evidence of water leakage from the internal stop cock. Have been losing pressure on a weekly basis and having to top it up on the boiler for months now and never known the source of the problem, suspect it might be that now.
Thanks again, the ever helpful twtd community. | | | |

Yes, I did wonder that, having had issues with the cistern flush system recently, which I recently replaced, although I didn't get round to taking off the cistern to replace the diaphragm.
As it is, replacing the system and reducing the cold water flow into the cistern has made the problem go away for now.
If it comes back, I'll replace the diaphragm with the one that came with the cistern flush system that I bought. [Post edited 20 Jul 2023 7:58]

Aaaaand it’s back. Darn. Sounds like it’s coming from where the dishwasher is plumbed in but I can’t access the pipe work very easily. Must be a hardware issue, a valve or something. One for the professionals I think. | | | |

That is the plumbing advice I would expect from an IT professional. |  |

Actually water hammer may my problem, and one solution the following suggests, which I have tried with success, is to cut down the water pressure into the house, and the cistern.

Incidentally, one solution it suggests is to turn off at the mains and open every tap to drain the system. Does this involve completely emptying the water from the cold water tank in my roof because that is where the cold water in my bathroom taps comes from? [Post edited 20 Jul 2023 8:34]

You won't cure water hammer by draining and refilling, that's nonsense.
It's usually down to a change in the system somewhere. So increased pressure from the water board, a break down in a component or something as silly as the neighbours running a hose on a shared main.
Something else to bear in mind is new water meters have non return valves in, so water can't expand back down the pipe. So if you've recently had a new meter fitted, it may account for it.
You can try turning the main down a turn or two at the road, this sometimes helps. It sometimes goes away on its own as the pressure in the main changes. Or have a shock arrestor fitted, a small expansion vessel to soak up the vibrations. |  | | |

That's very helpful. I hadn't thought about turning the main down at the road. | | | |
