    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 the room 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.

    25mm blue MDPE is fine unless you have ground contamination issues

    Thanks so much for this.
    Can I ask one more silly question.

    What is hydrodare? A number of people have recommended to me to use it as a conduit for a Cat6 cable to the garden room. And I wondered if that would suit for water as well? I could buy a large roll for cheap as kill two birds with one stone.

    Final silly question.


    I’ll be taking the tee from this tap. I’ll be removing the steps cos I’m putting in a patio; and was thinking of coming into the house below ground level and come up on the inside of that wall to the meet the water pipe that feeds the outside pipe.

    Are there any damp issues that I need to be aware of?

    Thank you.

    If you are relying on winning the lotto it is so unlikely is is not worth doing anything. Even if you did by some fluke win you would almost certainly upgrade to a new house anyway.

    Thanks. It's just a turn of phrase that we use in Ireland.

    Any view on the questions? All advice gratefully received.
