I have a church with living quarters they used to be two seperate properties. Two dno tn-s supplied into either end of each building.! There is one boiler to do the lot, one water supply one gas supply. The boiler is supplied via one dno but main bonded via the other dno supply.! Any thoughts if there should be main bonding from both dno to where water rnters both properties? Any gaps ive left out ill try fill in!
