Done and dusted. It was a lot easier than I expected.

Thanks for all the help and offers of help, especially to dontknowitall - I wouldnt have even tackled it without your help and advice. I owe you a pint, cheers mate.

I'm glad you got it sorted, just make sure there's no slow drip from the fibe washer and the float is secured.

Personally I only ever change the whole ballvalve if its totally scaled up etc. I just split it and replace all the internal parts including split pin, will be good for another twenty years. Ballvalves are getting more and more expensive and its silly to keep of scrapping a decent valve just because the washer and seat are worn. Too many things are just chucked out these days when they can be easily repaired.

I do the same with toilet siphons, why carry 3 or 4 bulky siphons when you can carry a selection of diaphrams and a rubble sack and some rubber seals. I do have spare ones if really need them though.

Cheers for the advice. I've popped up once or twice to check and will continue to do so for a few days, but all seems good so far. I was thinking of sticking a bit of plumbers mait around the connections, just as an extra layer of seal - is that advisable?

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.

 

[robbieh]

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?

 

[dontknowitall]

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?

 

[robbieh]

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