Moving stop cock

[danzx2]

Hi guys,

I'm looking to move the stop cock closer to wall rather than 2 foot from it.

Also extending 2 pipes hot/cold that go to the kitchen extension.

Please see the photos below:

Other than turning off main cock in the street, draining down, breaking up floor should this be possible? Its a plastic main pipe.

How deep does the main pipe normally go down vertically and what depth should I break the floor to?

Thanks

Dan

Does anyone know? What would a rough cost be? I would dig out around the pipe so it would just be extending the 2 copper pipes from the kitchen and extending the main pipe to the wall.

Thanks

I'm only somewhat familiar with the different types of black mains pipes used over decades, which is fairly typical of generalists and more so of gas men. Hard to tell from the pic. It often means getting an expensive universal connector to go to copper or MDPE to change things.
Sometimes that has to be in a difficult position.

Some were "alkathene" - try a search on that.

It would be done by someone seeing it and guesstimating how long it would take, and maybe allowing a hassle factor. There's always something else to consider!

Thanks for the reply. I think it is alkathene as it is more flexible than MDPE from what I know.

I'll have a search

Probably 1/2"class D alkathene - that`s a 3/4 compression fitting on the stopcock - you can still get 3/4 olives for the ( bigger) 22mm compression fittings

Morning,
Just an aside from the main topic but noticed the floor tiles - it would be worthwhile getting them checked for asbestos as its quite common in those tiles.
Just before you start breaking the floor up.


cheers

One other point to mention is that the stopcock also needs to be 750mm from an outside wall or be suitably lagged to provide frost protection. The pipe should be 762mm deep (2'6").

At least in an ideal world but gives you a bit of a guide as to what your aiming for.

Agreed, they should be double bagged and treated as containing asbestos, although they are low grade risk where the necessary PPE.

Thanks for that guys. I was going pop the tiles up and SDS the floor. I'll be ultra careful with them.

Have brother in law coming over in about an hour to price up the work.

The new location of the pipe would be next to an internal wall anyway in the middle of the house.

Thanks again

All done now.

I used a 3/4" olive that fitted the alkathene pipe perfectly. It also had a copper insert that I reused. Standard 22mm compression reducer to the pipe.

Thanks for the advice!
