Hello there, I wonder if any one could help me?
I want to replace the pressure relief valve as over time it keeps releasing the pressure and I periodically need to re pressurise.
It looks like there are two 3mm grub screws top and bottom that hold it in place?
These are solid and I've tried getting the blowtorch on them but no luck yet. I don't want to strip the hex head bit.
The other small prob is the low pressure switch. I thought this was just an on/off switch or does the PCB look for ohms? When the pressure is low, measuring across the 2 terminals there is a circuit as you'd expect and when the system is filled the circuit is broken.
However when I plug in the 2 yellow wires the LED is back on??
I'm guessing a need a new switch but I'm scratching my head about this, because it seems to be working as it should.
Any illumination appreciated
