Clean up the area you’re going to be working in.
Turn water off, remove cap and clean thread. This is an improvised Franz nut which is a 3/4” hex socket with slits grinded into it.
**We will be using flat cover plates for this going forward as it lines the copper up with an adjustable tee bracket without needing to offset the copper.
Dummy fit cover plate, mark where the thread is to be cut, remove cover plate.
Grind off to mark.
Use clear silicone to stick the cover plate to the wall. Rotate cover plate as the silicone touches to prevent it from squeezing out. If any does come out, wipe clean with a rag and methylated spirits.
Thread tape with 5-8 wraps of grey teflon.
Wind on the boundary valve fitting.
Use the red fibre washer to seal between the fitting and the boundary valve.
Install boundary valve.
Ensure it is level.
Mark a level line down the wall for your tee bracket.
Install the 50mm adjustable tee bracket using green plugs and button screws.
Replace the copper olive for a nylon olive.
Bend your 3/4” copper so that it is slightly above the footing. We are aiming for 300mm cover to finished ground height (approx 75mm below the render line here)
Line up the copper and the poly in the ground and cut to suit.
Install approx 500mm of 3/4” chemlag over the copper.
Use a 25mm clip head which fits snug around the chemlag.
Tighten nuts.
Use tap grease on the o-ring for the poly fitting.
Loosen but don’t take off the brown side fitting and slide over the copper.
Hand tighten
Mark poly to centre of fitting.
Clean poly of any dirt and if there is little marks use emory paper to sand it back to a smooth surface.
Connect poly to fitting. Tighten both sides using multigrips.
Turn isolation valve off and turn water on at meter to test connections before backfilling.
Find some sand (there’s usually some on site or a neighbouring site) Be resourceful
Install sand around pipe 75mm under and around.
Backfill.
