Hi
My next door neighbour recently replaced his mains water pipe. United Utilities let him dig his own trench and lay blue MDPE 25mm polypipe. As long as their spec was adhered to, i.e trench depth….. etc etc….
I want to do the same and replace the old pipe in the front garden. I read somewhere that you need a stopcock and drain valve as a first stage as the pipe comes into the house. I would like to extend a water supply to my shed/garage building in the back garden which is about 40m away from where the main enters the house. I could run it from the mains input to the back of the house, underneath the floor then in a trench starting in the back garden.
I’ve drawn the following diagram, but not being a plumber, I’m not sure if this is the best way of doing it. Ideally I would like to keep the pressure as high as possible for the garden supply. The house only has 15mm leading to system.
1. What’s the best way to do this ?
2. Do I need a NRV as indicated on diagram ?
3. Does UT need to be told about doing the back garden feed ?
4. Would UT need to ok the back garden feed, trenches etc as per the front garden ?
5. The back might be installed separately after the new front house mains, is this ok ?
Any help with this much appreciated, thanks in advance
