Hi.I have recently had to have the condensate trap replaced due to the old one leaking.About an hour after being replaced the pressure started to drop rapidly.I kept topping up the pressure to 1.5 bar or slighty above but whithin an hour the neon light indicating a fault started flashing.The enginner that fitted the trap seems to think there might be a leak in the system.There is no leak from upstairs so the only place it can be coming from is under the floor boards in the front room.This is would only be accesible if i pulled up the wood floor which i dont want to do!NO DIY work has been done in the house so no nails or anything has been hammerd into the pipes.Any help would be very helpful.
