The water pressure switch on my Potterton 80E is kaput - I know this because the
boiler fires and works fine when I've disconnected the switch,
but the low pressure light is on when I reconnect.
I've heard that one can leave the switch disconnected 'as a temporary fix'. My
question is: how long is 'temporary' in this context, and what are
the possible negative consequences of leaving it off?
I'll be installing a new one ASAP, but right now I'm cold, the dishes are dirty
and my wife is upset!
Any help greatly appreciated.
If it is only for a couple of days, or a week or so, then you won't really
effect anything. Just keep an eye on it and make sure the system is not
bubbling and making weird and wonderful noises. But the device is there for
safety reasons, so it is not recommended to leave it off line for prolonged
periods of running the system. The ideal situation is to order the part and
make sure it is going to arrive before you do the workaround of removing the
This switch is a low pressure switch.
The pressure releif valve is what stops the boiler exploding.
However if you toast your boilerif there is no water in it - as you have
disconnected the switch - then that will be your loss.
