Hello All
I've read many many posts over the years on here, and always get great help, but now I've had to join to get a (hopefully) more specific answer.
My Optima 701 has an over pressure problem - as like all the other posts, it starts at 1bar cold, then rises to 3bar, ejects the excess pressure and so on goes the cycle.
I've done as recommended on the other posts, by emptying the system pressure and pressurizing the EXV to 0.7 bar, 1.2 bar and 1.5 bar but nothing is stopping the system from over pressurizing.
The only way I've been getting marginal relief is by leaving an air head in the bathroom rad.
Am I correct in thinking that the EXV would show as failed by ejecting water from the Schrader valve? because it isn't.
Any ideas?
I'm thinking of sticking an 8 litre external vessel in, hoping that this would cure it.
All answers gratefully received.
