Mains water feed relocation

[NBW]

Hi everyone

We are having some work done and moving the kitchen from the front to the side of the property.  The builder has suggested to channel out the floor and run the water feed  along the study floor and in the ceiling, down to the new location.  I have concerns about this.  We have UFH downstairs so the cold water will be heated.  The UFH will be laid on top so will be extremely expensive if we have a leak

 

I have suggested we wait until the scaffolding comes down and we run the cold water feed outside in 25mm to the utility where we can tee off to where the feeds are required

 

Any other thoughts? Is this the best method to relocate the water?

 

Thanks

Maybe you can mark on the floor plan which areas have u/floor heating and whether they are suspended floor or solid slab. 

Also what sort of water/heating system - gravity fed or mains pressure etc and where the cylinder and boiler are going etc. Are you siting a water softener anywhere ?

It is obviously common to run pipes from the cylinder/boiler to the upstairs outlets through the ceiling void, but mains pressure systems commonly have a balanced cold feed from a pressure reducing valve sited near the cylinder.

What does the upstairs layout look like ?

Where are the u/floor heating manifold(s) ?

 

Moving the supply pipe like you suggest seems like it would be better.

 

If you are having a solid slab floor with u/floor heating pipes embedded, definitely make sure you have some conduit put in to allow insulated pipes to be run through the conduit to your kitchen outlets e.g. to the kitchen island.

Where would you want a stop tap for the house - in the utility ? Where would you want an outside tap ?

Do you want a tap outside a garden shed while you are about it ?
