it is probably the non return valve which vent off through the pressure switch sorry its late if someone has already said it but im a compressor engineer but havnt read the replies lol
It'll be all right ,just gota remember to turn it off ... boom! Can they have to much pressure and pop ?
Bought a new pressure switch, seller accepted an offer of £7 posted. Fitting it tomorrow hope it works ok. http://www.ebay.co.uk/itm/270963783715?_trksid=p2059210.m2749.l2649&ssPageName=STRK:MEBIDX:IT
Let me know how you get on removing the old one, mine appears to have been fitted with killer loctite.
Took the new switch apart and the seal was completely different so swapped the whole unit over. Wasn't too hard to take apart used PTFE tape when I put it back together. Compressor is back working again
mine is the same compressor and the seal in the non return valve has split, can you get new seals or is it a new valve ? @TomEv86
same as the one in the photo's, but that's a sealey one, probably a cheap Chinese one with there badge ?
