Incoming Water Supply

[richo106]

Hi All

 

I am planning my renovation project that it is hopefully starting in the next couple of months

 

Currently my incoming water supply comes up through my kitchen floor (concrete slab) in 15mm copper to the stop tap

 

The stop tap in the road is the blue pipe so there must be a joint where is changes to copper, is there anywhere normally this is done?

 

The location of the incoming mains needs to be moved anyway, would people recommend to bring it in to the house in the blue plastic pipe?

 

One more question where is normally the best place to bring the mains in, in the kitchen near the sink or into the plant room where the boiler/ASHP will be located? or does not really matter?

 

Many Thanks

When we demolished and rebuilt we put in new blue 32mm MDPE from our side of the main stop to the plant room in our case. From there it transitions to copper and after an isolator goes into a pressure reducing valve and then into the general plumbing circuit.

 

Where you bring it into the house is a discussion for you and your plumber but if you have a plant room then that would make make sense. Space under sink will be limited also.

Where exactly is the stop tap? In road or footpath / verge? Of it's safe to do so, flip the lit open and if it's not bunged up with dirt, you might be able to see the outgoing pipe type. But either way, you'd only replace your pipe as far as the edge of the boundary and connect there.

It could be anywhere. For us, the water company's side of the stop tap was MDPE and ours was all led.

Yes, one contagious run from the stop tap, avoid joins underground where possible.

Entirely up to you and very much dependent on your site plan vs how much effort you want to put in. Ours was a pretty long "Shepard's crook" run from the front stop tap, down the side of the house, around the back and until our current utility room. We could have halved the run and brought it up under kitchen sink instead. When we remodel this is likely what we will do. I'd avoid taking up valuable kitchen space where ever possible.

It’s in the footpath at the end of the my driveway. It’s definitely 32mm blue PVC pipe heading towards my property. But them must change to copper, i just need to find where that ia. Hopefully once I break the floor out I will have a better idea

TBH, 50m of blue 32mm MPDE is not expensive (under £100 inc VAT) so that should get you from boundary to inside your plant room in one run, even if it needs to take a long way round.

 

Do you have outside taps? Are they fed off the house supply or from the mains run to the house.

 

Not a big deal to T off the 32mm to a smaller bore for these as long as you fit a non return valve at the tap itself.
