Ducting pipe for water supply pipe.

[mickstep]

Hi, I am renovating a house, and when I had a water meter fitted I took the opportunity to replace the lead supply pipe.

It's only a short 2 meter run from the meter to the kitchen and I managed to source some 25mm MDPE pipe by asking a builder for any offcuts they had lying around at a building site round the corner from my house.

However according to this a PDF I can't post a link to from Anglian water I will need an extremely short amount of 100mm ducting pipe, less than 500mm to protect the pipe as it passes through the wall of the house.

Has anyone got any idea how I can acquire this ducting pipe without having to buy 50m of the stuff? The nearby building site didn't have any offcuts of this lying around. Is anyone willing to post me some for a few bob on paypal?

Also, the pdf mentions the pipe should be buried at >750mm this to me since completely pointless since where the pipe enters the water meter is no more than 400mm, if the pipe will freeze it's going to freeze at that point whether or not I bury my pipe at 750mm.

Thanks

It's not up to you to decide what's pointless or not. If it freezes on the supplies side then that's their fault, if its on yours and you haven't followed the guidance then its yours with all the associated costs.

Just use a piece of 110mm soil pipe.

Consult the WRAS guide if you don't know what you're doing....

The thing is because of the extremely short run between where the water meter is and where the pipe enters the house, about metre, I don't think it's even possible due to the rigidity of the pipe to get it down that low, I have it deeper than the lead that came out.

Thanks for the advice.

In which case I would get it I writing from your WS that its ok to leave it like this but I bet you don't don't get a response in the short term.

Ask for a sit visit and get the chaps detail when he says its ok.

I'm in no hurry to backfill so I can wait for them. I suppose if needs be I can get it lower with a couple of elbows FWIW.

Thanks for your help.

That would my route.

you can always lagg the pipework thats not 750 down for added peace of mind.

as for the sleeve, your best bet is of a builder/building site.

http://www.wras.co.uk/pdf_files/Info note Schedule 2 paragraph 7 explained.pdf
(4) Any water fitting laid
below ground level shall
have a depth of cover
sufficient to prevent water
freezing in the fitting.
G7.7
Wherever practicable and except for pipes laid under a building, the vertical distance
between the top of every water pipe installed below ground and the finished ground
level should be:
a. not less than 750mm; and
b. not more than 1,350mm
G7.8
Where compliance with the minimum cover of 750mm is impracticable, and with the
written approval of the Water Undertaker, the water fittings should be installed as deep
as is practicable below the finished ground level and be adequately protected against
damage from freezing and from any other cause.

highlighted the relevant bits,
to my mind this translates to pipe less than 750mm being insulated inside a duct and with a slab above for added protection, but I wasn't able to find where this was from.

Go to civils merchant and get 75mm slow bend and 3m length of duct. Burdens, key line , Travis Perkins. Cut duct in half connect each half to either end of bend. Measure what u need and cut off. Wham. Cost u about. £15
