Lead replacement

[firekill]

We have a long run of 55m of half inch lead pipe on our water supply. The pressure and flow are not great so we are thinking of replacing the whole lot with plastic.
Quoted £1250 using the mole method so there is no trenches dug out .

Price seems ok but we are going to block pave the area afterwards and need to know if it causes the ground to sink at all as I can,t see how the hole can be backfilled.It must leave a slight void .

We are in notts so any reccommendations will be appreciated

Having had this done at my previous address i don't think you have anything to worry about. the settlement is not worth mentioning.
