Plumbing question

randomi15

Hi Guys,

I am changing my main led pipe to mdpe.

I have lifted all floorboards up and at the moment have some questions as follow.

What do you use to join led to mpde? Would it be a coupler or universal joint?
I guess led is 22mm and my mpde is 25 so need a 25 to 22 coupler?

Can you please let me know of anything I should be aware of?

I am only changing the pipe from its enterence to the house . when the pipe enters the house would it be inside a trench or ran in with concreate around it?

I am trying to work out how easy it will be to push the mpde out to connect it just before the pipe entering the house.

Would you use mpde or copper stopcock

Many thanks

I would pay someone to replace the whole thing. The people I used to do mine dug a hole by the house and a hole by the meter and they used a 'mole' to dig a small tunnel which they inserted the new pipe. They ran this through the old hole in the wall and then connected it to the rest of the pipework.

I'm the same. If I were doing it, I'd do it all, back to the meter.

I agree with the two above, however if you aren't going to do that then you need a lead to copper coupler, I doubt the lead is 22mm it will normally be 1/2" but lead size isn't measured in physical size it's measured in weight normally 6 or 7 lb
