rocket giotto evoluzione v2 noisy and weak flow plumbed in
I have a rocket giotto evoluzione v2, had it about 5 years and it's always been plumbed in.
We moved house about a year ago, and I changed the inline water filter. It was a bombora src 121 but I got the equivalent 3M replacement.
Not sure what's going on but about a week after I changed the filter the machine got very noisy and the pressure gauge flutters when pumping. The flow from the group head also seems weak. If I switch to tank supply it runs fine, nice and quiet with good flow. If I switch back to line supply, it will run nice and quiet for a few minutes but slowly returns back to noisy pumping with weak flow and fluttering pressure.
Any ideas on what's going on here?
How old is your current filter?
It might need replacing due to sediment containment which has come through your water supply.
