At present there is one stopcock for 4 houses which are supplied with lead. Whilst doing the drainage for my extension, I want to replace the section under the new slab and into the house with MDPE pipe. Outside and underground, I want to install a stopcock (depth around
750mm) with lead on one side and MDPE on the other. I may have to leadloc to MDPE so that the stopcock is MDPE both sides I guess. Where would I get a solid metal underground stopcock in a shaft for this purpose ? Also, how is the MPDE installed underground - insulated, in pea shingle etc ? Can it rise unprotected through a new floor slab into the house ? Cheers, Simon.- posted
