New stopcock and pipes

Kai_63

For reasons I won't bore you with, my neighbour's builder replaced my old metal stopcock and pipes with new plastic fittings without asking me. I'm now trying to make sure the work is OK or whether to get it done again.

He hasn't fitted to the wall - what is the best approach for this as I now have a water hammer issue as well!

He fitted the Plasson 3407 stopcock which seems to be WRAS approved. And used FloPlast MDPE pipe coil for the pipe work.

Any advice welcome as to the best approach on all of this as right now I have the time to get it right!

Sorry I'm not at home at the moment so only have this one. Will share more later.

I don't see any problem with plastic pipes and stopcock.

Water hammer possibly happens because you now have higher flow than you used to have. You can try reducing it by partly closing the stopcock or the isolating valve of the device that coses it.

Oh interesting. I thought the fact that it's not secured (I can literally move the pipe and stopcock was affecting it). Will try reducing it a little once they've fitted it to the wall.

Yes, an unsupported pipe can, and often will, cause hammer. 
Which outlets in your home cause it to 'ammer? And is it a single 'bang', or a continued shudder?
Now't wrong with these plastic fittings, in fact I'd choose them over brass, as these tend to seize over time.
Do you know if your mains pressure is pretty high?
Anyhoo, yes, I'd look at clipping the pipe, immediately above the s/c, and roughly every metre. Looks like you'll need to make up timber or ply spaces to fit between the clip and the back wall.

Even better - ask the builder to do it.
