The owner of my unit contacted rocket plumbing due to a leak in the kitchen of my unit being that the owner lives in ny, he chose rocket plumbing based on the great ratings he did the right thing! The cost of repairing your boiler is more than replacing it. Great customer service! very trustworthy people!! The boiler replacement scheme has been very successful to date with over , old and inefficient boilers being replaced. Is drain out bathroom septic safe? It isn't.
