'What cost you £400 m4rky?
Clearly you have no idea what is involved or why you have a malfunction. Good luck
Originally we had a leak from the diverter valve area. A part was replaced and it still leaked but not as bad as before. The system was then chemically cleaned and now the central heating only works a little bit. So I feel like I have forked out a lot of money to be in a worse state.
You are correct I don't know what is involved or why my heating is not working. I have lost trust with my plumber as he doesn't seem to be explaining well what it is I am paying for.
So I am trying to find out if what he saying about the boiler is possible/correct. I thought he had already replaced the diverter valve cartridge four weeks ago and now he is saying it needs replacing again but also needs a motor.
I don't see why I should pay again to replace a part that is four weeks old.
Also when he replaced the valve cartridge he said that he could not guarantee the fix unless the system had a chemical flush. So we had this done.
I have spoken again with the plumber and he is now saying that he did not replace the valve cartridge he just repaired it.
Also that it needs a new diverter valve (not just a cartridge) and motor (at a further cost of £230), therefore it is a different fault so not covered by the original fix.
He says you cannot replace just the cartridge on my boiler, it needs a whole new diverter valve.
Now from help on this forum I now what he means about not being able to replace the cartridge on a diverter valve with a bypass.
However, I do not believe my diverter valve is one with a bypass.
It doesn't seem to have the bypass pipe around the back of the valve.
So back to my original problem.
