Roz Posted May 19, 2019 Share Posted May 19, 2019 Hi everyone Our groundworkers for our utilities are almost done and the water pipe is just outside where our kitchen will be. We're planning on having a building site supply so need to get this pipe ready for a water connection by having it feed into an outdoor tap find to the wall I presume, and we can later go into the property. Does anyone have any pointers of what I need to do to make this blue pipe into a ready tap?? I don't know where to start. Link to comment Share on other sites More sharing options...
PeterW Posted May 19, 2019 Share Posted May 19, 2019 Tee into a 20/25mm MDPE stub MDPE to 15mm copper gate valve 15mm pipe Double check valve 15mm pipe wall plate elbow tap Allows you to isolate the tap in winter and also the DCV meets water regs 2 Link to comment Share on other sites More sharing options...

I came across this diagram about temporary building site supplies. This is from Anglian water and we are South West Water, but might this apply? Our blue pipe is just sticking up out of the ground and doesnt have any sort of insulation... 1 Link to comment Share on other sites More sharing options...
Temp Posted May 19, 2019 Share Posted May 19, 2019 You can get MDPE check valves and brass taps with an MDPE backplate for mounting on a temporary post. Get one to match the size of MDPE pipe you have. Link to comment Share on other sites More sharing options...

Anglian Water were OK with my builder's standpipe being commissioned without insulation below ground ground, the surveyor was more concerned about the absence of an above ground insulated box to protect things up to the tap. I never bothered and it survived the winter in Lincolnshire with just regular pipe insulation above ground. Various seasoned builders and also @JSHarrishere said MDPE pipe is not prone to freezing, worry more about the metal fittings. p.s. I won't be cutting corners with the insulation of the permanent mains feed into the house. Link to comment Share on other sites More sharing options...

Mine was a complicated case: Builder stand pipe fitted on post 2 meters inside the boundary fence. Removed standpipe and routed 22m of MDPE through house foundation tench to static caravan. Spliced into the static caravan feed to create another temp branch for laundry in garden shed and also an outside water tap on the shed wall for building activities. Spliced again into the static caravan branch to route another temp branch off to feed the garage before the house is built. When the house is weather tight and needs water for plumbing testing, while we still live in the static caravan, I will be able to pressurise the house from the garage.

redtop Posted September 15, 2019 Share Posted September 15, 2019 just sorting the bits for our temp supply, did it all in MDPE but havnt ordered a stop cock as i figured it was only feeding a tap so why would i need a stop cock. or am i missing something :-) oh our feed is 32mm so i have gone for mdpe 32mm double check valve, mdpe 32mm to 25mm reducer, mdpe 25mm to 3/4" wall plate / tap (with check valve built in) Link to comment Share on other sites More sharing options...
Ferdinand Posted September 16, 2019 Share Posted September 16, 2019 (edited) Be sure you are aware of just how bendy the blue pipe is .... not a lot. And what that will say for radii of bends etc. F Edited September 16, 2019 by Ferdinand Link to comment Share on other sites More sharing options...

Stopcock just before that with a section of 110mm waste pipe as an access sleeve is also a good idea as otherwise you need to keep turning off water at mains to service the tap.
