    Mains Water Pipe Noise - ONLY At Night

    Hi Carl, No there is no slow drip/trickle from any of the taps. Last night we drained the system as well, and nothing is improving the situation. Could it be air in the system?

    Mains Water Pipe Noise - ONLY At Night

    Hi John, In latest news...a make-shift arrestor has been fitted in the loft next to the water tank. Last night the noise was again occuring, louder than the last few nights (because I turned the pressure up on the PRV). I let some air out of the arrestor but this only reduced the sound and...

    Mains Water Pipe Noise - ONLY At Night

    Hi, I need help with a problem that's been causing me sleepless nights for weeks! It's driving me mad. Around 1am each morning, the mains water supply pipe to the house starts vibrating causing lots of noise (sounds like the noise is coming from far away, then reaches a peak and stops for...
