My appologies that I am bringing up the lead pipe replacement subject again. I have read previous threads on this and other sites and none come close to solving my problem.
Sorry if the background drags on a bit.
I have purchased an end terrace 'villa' in South Wales, built about 1910 - 15. It is built into the side of the hill, with the front door about 3m above road level and the ground at the rear at first floor level. An alley runs along the side of the property (about 800mm wide), this has the gable end of the house to the right and a 500mm to 2500mm retaining wall to the left.
The terrace is four properties long with shared sewerage. This runs under the rear of the terrace and turns 90 degrees into my side alley at a depth of about 1000 - 1250mm depth. This sewer would have been 'adopted' in 2011 by Welsh Water. The inspection chamber at the 90 degree turn is in need of maintenance as the brickwork is bulging, Welsh Water have been notified.
For the first 1500mm of the alley the left hand side carries the incoming gas pipe (depth unknown).
The alley also contains the incoming lead water pipe. This appears, from test holes, to run just below the concrete path (100 - 150mm depth).
The route up from the front wall to the front of the house presents few problems as there is room for the new pipe to run next to the old.
We have consulted with Welsh Water who have said that they are happy for us to dig the trench, lay the pipe etc.
As mentioned above the side alley is a bit busy for it's 800mm width, (footings for retaining wall, sewer, water pipe, gas pipe, gable end footing)!
Welsh Water want the new pipe 750mm down, 600mm below existing lead pipe.
Can I move the stopcock to inside the front door and take a copper pipe upto the ceiling and through to the kitchen that way?
At the moment I have both an internal and external stopcock at house level (3750mm above Welsh Water stopcock). Do I need to keep an external stopcock? and is any additional 'non return' valve required?
The answer to these questions, or suggesting other ways we can avoid digging the alley would be gratefully recieved, Thank you

- They just need to inspect the trench depth (750mm) and pipe before backfilling.
- They will connect the pipe free of charge to their supply.
