Minus 10 here last night. Even though I've got a greenhouse heater with frost stat in the shed the pipework to my RO was frozen. The relay box doesn't seem to be working - it should throw the relays to start the pump and open the water inlet solenoid but there's no 'click' - bit ominous
The water pipe from my outside tap to my shed is garden hose with 3" foam rubber insulation and a wooden trunking but that's frozen solid too.
I won't be able to assess the damage till I've got the water supply to the shed running again - I'll have to dismantle the trunking, take off the insulation and douse the pipe with hot water to free it up.
I bypassed the auto control box and tested the pump and inlet solenoid - they're both working - just hope I haven't b******d the membrane, the pipes to and from were frozen.
I thought I'd taken all necessary precautions but some things you can't predict.
Our Christmas trip is off, too - weather is bl***y awful and I can't go leaving the RO not working.
