All looking good this morning with no leaks inside!
Got to put the outside tap on and screw it to the wall later today. I'll put a good slug of mastic behind the flange plate to seal the pipe entry and use brass or st/st screws.
Need to then I think reinstate some sort of meter "pit" around where this stop cock is just inside the fence. The side you can't see is still iron, about 10' or so that runs under the fence to the meter at the roadside. Think that bits on borrowed time but if it does go it's down to the water board. I just went to make it easy for them!
One thought was to carefully cut down a blue plastic barrel with lid, sink that level and then fill with loose EPS packing type beads. If it did need to be accessed later I could just unscrew the lid and scoop out the EPS?
(Then backfill the trench half depth, put in the CCTV duct etc).
P.S. A big thanks to all for taking the patience whilst I relearnt my plumbing skills (if I ever had any). Hopefully the marks on Nick's forehead where he's been banging it against the wall will fade.....
