Having read other topics on this subject we are fairly sure that our PRV needs replacing. However will we also need to replace the expansion vessel or could it just be the PRV?
If we need to replace the expansion vessel, do we need to buy a Glow Worm one or not? Also, can you add the new one to the heating return, and if so will the system work with the faulty one still in place?
I would appreciate any help I can get on this one.
Thanks!
