Hi all, New to the Plumbing forum, this is my first post.
Potterton Perfoma 28 Boiler, 7 years old from new, in the last 6 months the boilers pressure has been at or below 0.5Bar, the hot water tap would go from scorching hot to tepid to luke warm in a space of a minute when run on full.
Tried topping up the boilers central heating system through the filling loop which was already attached? so i followed the procedure by switching the boiler off, and with the system at cold i opened the cold filling loop valve to 1Bar, bled the radiators, (the highest Rad had lots n lots of air trapped), then filled back upto 1Bar. Ran okay for a day, although i cant recall what the hot water tap was like at this stage.
inspected the boiler with the front cover off and found that the differential valve body was leaking where its connected to the 3-way diverter valve body.
Now, this isn't my boiler, but the company who is contracted to maintain and service this boiler for a family member has told a member of my family that they need a new boiler, just after they 'serviced' it. but all they did was scrape the limescale build up on the heat exchanger plate. A while after this another boiler engineer of a big firm (i wont name names), came round to my familys household to perform another 'service' but shortly after leaving they left my family without running hot water & central heating.
After i inspected the boiler to see why the pressure keeps dropping i narrowed it down to this. See attached Pictures
I notice that the green sludge build up is a form of bacteria, could be giardia? at worse case? so i can understand that this is a health risk.
I am quite temped to fix this issue myself, i have repaired quite a majority of things so I'm confident with spanners and that. but i have researched that i can buy a complete diverter valve diaphragm kit including all the rubber 'O' rings and green nylon washers for £30 (Baxi branded)
any tips much appreciated, thank you for reading
