Asked to replace some old single rads for doubles. open vented indirect cylinder system without any motorised valves. 5 rads were 2 pipe, but other two looked 1 pipe and were connected to the hot water coil circuit.
Anyways removed the 1 pipe system , capping a pipe in the airing cupboard and then next to the boiler. I thought this all through before hand, trying to logically work out the system in my head. Everything was old pipe which made my pipe slice useless and to be honest i was starting to doubt my ability. Had i understood it correctly, have i capped the right pipes or would i get water through the ceiling?
Today was switch on day, and due to customers guilt came home before everything got fully hot. 1 hour later phone rings and customer tells me that heating wont come on. Asked him to check the pipes and everything cold apart from immeadiate boiler area. Airlock? did i cut the right pipes? What have i done?
Came away from the call feeling sick and frantically trying to re question what i`d done and my thinking.
Then it hit me! Rang the customer and asked him to turn up the room stat..... which was on zero. Result! Customer loving the warmth and their plumber!
I realise many of you do this stuff standing on your head, but its the first time ive really been faced with mixed 1 and 2 pipe systems, first time ive actually changed a system rather than like for like stuff.
So im basking in pride right now , makes a nice change to fitting taps!
