I have a Vokera Linea range 24/28 I lost pressure and would not hold pressure
Called in a plumber who installed a external expansion vessel and said that was the problem
still unable to maitain pressure
The plumber did not isolate the old vessel is this necessary? have some water coming out of the overflow not that much
Can anybody help
If he has replaced the expansion vessel then the chances are if you are still losing water through the blow off to outside that the washer in the blow off valve has failed as well.This is a common problem brought on when an expansion vessel fails.
