Had this happen plenty of times before with my old trusty 450c, but it appears that it also happens with my new 444c dual pack
Whenever the temps drop below freezing, the check valve on the leader hose would freeze up, causing the compressor to run on and not fill the tank :mad:
In most cases, I can either tap the valve or pour some warm water over it to break free :o
I’d like to replace it with an SMC check valve, but not sure which one I should go with
