Fitting WRAS stopcock and pipes

[Kai1977]

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 right now I have the time to do it right!

Need a little more information please. The Plasson is likely fine, but worth checking any IRN (Installation Requirement Notice). Is the MDPE below ground?

 

[Kai1977]

Thanks. I can't tell how far down the MDPE runs. Anything I should be aware of? Will check the IRN too.

Sorry not at home but here's the one photo I have at the moment.

Where does that blue mdpe run? If you do have it below ground it should be moled or in a trench between 750mm and 1350mm.

I don't know but I would assume out to the external mains pipe (it's a converted Victorian house so these internal stopcocks were in the shared hallway). I will ask them about the trench.

Depending on where you are - it may be a requirement for the installer to run the mains and then get the water company out to either check the trench or check the accesses, if moled. Some also require that it is themselves that make the final connection to the mains.

Depending on how far you wish to take it, a call to the supplier to confirm what their requirement would be, in the case of a new mains going in, might be in order.

Normally the pipe should be within an insullated duct.
