Garden Room Water Supply

karlitob

Hi

Question: What size/type pipe do I need to supply water to a garden room.

Background: I'm about the dig up and lay a new patio/drive. While I'm at it, I'm laying cable, waste and water in a trench for a garden room that I might put in in a few years when I win the lotto. Its a pipe dream at the moment (pun intended). The garden room is 45m away from the house. I'm not sure if I'll even have a toilet in there - only a general plan of what it would look like. And if there is one - it'll be used once in a blue moon.

I'll be taking a tee somehow or other from the exterior tap which I presume is a 1/2" pipe.

I've read that there is MDPE and HDPE pipe. I've also read about hydrodare.

Would appreciate any guidance as to what type pipe and what size pipe over 45m? Thanks very much.

Hydrodare is brand of polyethylene pipe.not sure if it's HDPE or mdpe. For that run I'd suggest a 20mm bore.

If you're thinking of a toilet you'll need a proper waste, either 100mm gravity to the existing sewer or a Saniflo pumped system - which I think is 40mm. Not sure if they can pump the distance you need

Thanks so much. I had wondered if it was a brand name alright.

Can I ask - would you choose HDPE or MDPE, or does it make a difference?

Good call on the waste pipe - I have sufficient fall. Thanks for heads up.
