Plumbing a WM into a detached garage (with a slight twist?)

[Matmu1969]

Hi all

I've been contemplating putting a WM in my detached garage. the gaeage sits at a 45 degree angle from the house and is only 2 metres from the WMs current location under the stairs.

I have read the other posts on here re what pipe to use, how deep the pipe should be buried, and waste disposal etc. the dirty waste water drain is only about half a metre from the garage and was contemplating running the waste pipe down into an aco and then into that main drain.

My only obstacle is this, the garage, while very close to the water supply, is sitting on a concrete slab, about half a metre above the ground. Is this an impassable obstacle in terms of hard winter freezing etc?

The garage has an electricity supply though an RCD consumer unit!

Any advice?

na hire a diamond core and cut through it

bring all the pipes in/out in one spot

I'd pipe the waste straight to the drain. A build up of soap scum etc in the aco could start to hum....

Thanks, only prob with that is that i have to get to the drain from the detached garage, across a pathway/ginnel between house and garage! I am hoping that rain from the guttering which I will also feed into the aco, will keep it humfree (Humphrey?)

Might get away with it then, as long as its a combined drain. Dont discharge the W/M into a rainwater drain!

Cheers, its a waste water drain and the rain water will only be coming off the one half of the garage apex roof so I should be ok with it.

Interstingly, when I bring the pipework out of the ground and through the concrete slab, how would I do this and still protect from freezing conditions?

Cheers kevplumb, other posts suggest that lagging will only protect when piping is not open to the element. there is probably going to be a small section that will be outside! will this cause me problems?

btw, where in TN are you, my brother emigrated to TN, Greenbrier a few years back?

you can get exterior grade lagging or put a box round the pipes

cheers kevplumb, if i build a plywood box around it and fill with insulating foam, will this do the trick?
