Thread: Auto fill

I'm no expert, but I understood a water supply pipe can be laid shallower than 70cm deep, but it has to be insulated, if it is.

How I got around this, I bought some heavy duty pond hose (not the cheap spirally stuff that goes brittle) that was long enough to go between my shed and my house where, i T'd off the mains supply and then threaded the blue mdpe pipe through it. Then buried it in pea shingle alongside the waste pipe from the pond and then covered the shingle with soil etc...

I've had no issues with it freezing in winter when temps went sub-zero over the last two years.

almost no regs at all about laying pipes After they have exited the house via a double check valve hose union bib tap...
what would you class a hose pipe laid across the garden all winter...?

tempory site mains are left laying above ground in the mud most times....

i'd run it in mdpe insulate it and bury it as deep as you can easily manage.
mine is 20mm mdpe, 20mm thick insulation where it's clipped to the wall, and buried about 10" deep everywhere else.

How failsafe are the joints? I am in the process of getting the garden ready for a patio but have a join which would be under the patio which I believe is a No-no so was thinking of using a little access cover or something to be able to get to it should I have an issue ever. It will be about 8-10" underground by the time the patio is done but not sure I want to bury it and lay patio on top

Its what they are designed to do, get buried...
Just make sure you do a good joint.

You can get pushfit mdpe connectors but they can be a right bugger to get off if you connect it wrong...

Always used philmac fittings, just what i'm used to...

You could always electro fusion weld it...

Oh really? I used the JG pushfit pipes and have checked they are not leaking. I thought they was the weakness should there be a frost etc hence why access what required. If that is not the case I will just bury them! I have it sat right below the 4" waste pipe too so it might actually work to help insulate.

when you say JG push fit, you mean JG mdpe speedfit....

i did the same, put the mdpe under the 110mm drain pipe.
warm water from the drum going down the 110mm drain will help keep the mdpe from freezing in really harsh freezing weather...

Hiya

Thanks for taking time to share the images.

I guess Im a bit spooked as my daughters house has subsidence caused by a leaking drain - I will do as you have and run it above ground until it can cross the open garden. At least if there's ever a leak near the house we will see it :-)

Do you keep the autofill on all year?

cheers

stick a meter on it (£20) and you will know if there is ever a bad leak...
water is always on as i need to top up what the drum takes out...

That's the ones! I feel like if it was going to fail it would already have done so. That's one less headache by burying them then!

as long as you used the inserts, and pushed it fully home, it won't leak.

I did indeed, happy days!
