I have an Optima 701 boiler, which needs to have the pressure vessel recharged.
I've studied the diagrams in the manufacturer's manual, and climbed all over the boiler, but I just cannot find out where the valve is!
Can some kind soul point me in the right direction, please?
I'm no plumber, (an IT Engineer actually!), but I installed my central heating system myself in a previous property, about 15-18 years ago, courtesy of Texas Homecare, so I thought this should be a doddle!
