Evening all,
So I live in an apartment with a grundfos stn 2.0 b supplying everything in the apartment. Recently I had noticed the pump not cleanly shutting off (on off on off etc...) when the toilet cistern was almost finished filling. Took the easiest avenue first and investigated the ballcocks, new diaphragms etc ..
But no joy, so I looked to the shower pump and sure enough the pressure vessels were empty and don't seem to be holding pressure anymore.
So I go looking for spare vessels and for the life of me can't see any anywhere. Am I missing something or are grundfos just terrible to find spares for?
Anyone have any suggestions or ideas?
And am I on the right line with assuming this is the issue?
Thanks guys.
