.................... in a expansion vessel (CIMM 18 ltr EXE CE).
........... My father in law said that the system refills itself after a while so I thought it must be an automatic top up sealed system, ....
Where was this auto top up valve located?
SO
I'm going to remove the auto fill line from the attic as the father in law really cant access it where it is.
He has a large boiler room onto the house and the main water runs through there with loads of free pipe space.
I'm going to fit a filling loop and add a pressure gauge locally as well.
I'll fit the filling point to the return line to the boiler and I'll stick a pressure gauge and pressure relief valve on thier own tee'd line on the flow out of the boiler.
This system had a back boiler on it so the circ pump is on the return line should i swap it onto the flow out of the boiler?
Should i move the expansion vessel out into the boiler room and place it on the return line as well?
I going to add a magnaclean filter on the new return line set up that I will install in the boiler room.
I'll have to run discharge lines c/w tundishes from the relief valves in the boiler room to round of the job.
The hot water has an air vent added but I'm going to raise that of the ceiling on a wooden block maybe just so it can be found again in the loose blown insulation.
