Replaced some Mickey-mouse plastic pipe (by others) on my water utility service connection with a piece of galvanized iron pipe and a flexible "copper water heater connector" hose in place of a proper union because space was tight with odd angels, tree roots and other utility features.
Question - the soil is not corrosive in this area - any problem with this being underground?
HDepot had this standard copper flexible water heater connector and a second ss braided kind with no doubt a paper-thin plastic liner - just as the hookup hoses for a washing machine that is sold at a premium and IMHO is no better than standard hoses.
