Sorry to bump this thread. Everything seemed to be okay, however yesterday I was running the hot kitchen tap when there was an almighty vibration that continued for a short while after switching the tap off. I narrowed it down to the hot water pipe by the cylinder, and it seems to vibrate under the floorboards too. It is so loud at first I thought it was a helicopter over the house. Now it happens everytime I run the hot tap. If I run the cold tap it will stop until I switch off the cold tap, and if I run the hot and cold tap at the same time, and switch the hot tap off first, then it will not happen.

I've done a bit of googling and I'm guessing its water hammer?? I tried switching off the mains, running the hot kitchen tap empty, then slowly opened the main supply again (not all the way though) while the hot tap was still open, and waited for the splutter to subside. But its still happening.

Any ideas? Could it have been my changing the ball valve that has caused it? If so why now, a few weeks later?

If its at all relevent, dynorod were in the street a few days ago as there were some blocked drains, and I'm pretty sure they, or someone, was also messing with the brick water supply building thingy (I'm sure you know exactly what I mean), as I saw a few men in there. (Its in my estate by a central grassy bit, fenced off).

Thanks in advance fellas.

(Sorry if I should have posted a new thread, I posted here in case it was relevant to the ball valve issue)

When you changed the ballcock last time was it on the hot water supply tank or the smaller central heating tank? Sounds like the washer in the H/W tank is oscillating due to wear or a bit of crap in the seat.

It was in the hot water supply tank mate. I replaced the whole ball valve with a brand new one. I gave the supply pipe a clean and tightened all the nuts correctly. Whats the best way to rectify it? Is the vibration originating near the ball valve then, and resonating all over the house?

You can eliminate this by pressing down on the ball valve (so it starts filling the tank). If the water makes the hammer noise you know that's the fault (and faulty part). If not then it's something else. Why not give it a quick try?

I cant get in the attic just now, I'll try asap and let you know. cheers.
