Water main entry point

[WWilts]

Experienced groundworks subbie proposes water main entry point. (pics of ground floor, first floor, and both approx superimposed)

 

Barrier pipe required if going under permeable driveway.

 

Where would you put the entry point?

 

My instinct was nearer the existing standpipe.

Entrance lobby WC?  Pipes have to come down anyway....

Don't know your situation so...

 

You may need a water softener. You can check with your local water supplier what hardness your water supply is.

 

If you need a water softener you may need to consider where it will go and how the plumbing would work including the non softened water to any outside tap.

 

Good luck

Does underslab water main still need to be 750mm deep?

[dpmiller]

where will the outside tap be?

Under the kitchen sink, more room to add stopcock, change from  underground pipe to copper/plastic. Easy to get a main bond to it, there is a requirement for water at the sink anyway so makes sense, of course if you had plant room it would be there, even an attached garage I would consider it in there, just to keep access to the stopcock easy.

Thanks. Trench fill poured today, under the kitchen sink it is for the water mains entry. 

Hopefully will be able to run pipes (probably plastic) up and along the steel beam to supply the rest of the house. Including plumbing manifolds on (probably) upstairs landing recess, and boiler / cylinder in upstairs master en suite. That's bottom right in the first floor plan.

Don't relish many holes in the ordinary timber joists
