I have a '72 Chieftain that I've already put $3600 into. It still has the old steel fresh water tank and an air compressor instead of a pump. I'll be replacing it all next year. In the meantime, I thought the motor blew up in the compressor. Upon further inspection, it appears as though the pressure switch is the culprit. The motor works fine when I connect an outside 12 volt source to it.
Here's my question. Do they still make pressure switches for these old things? Where can I get one? And...do I dare bypass the switch and keep a close eye on the tank pressure? Thanks!

Mark;
I have the same set up on my 72 Chieftain. The pressure switch on mine does not work properly. It never completely stops. It will cycle forever. I usually fill the tanks and pressurize them then I turn the compressor off. When the pressure that the water comes out of the faucet starts to drop, I just recharge it.

You could try to install a pressure switch for a home well system . you can get one from any home center or hardware store for about 15 bucks . you will have to install a T in-line if there isn't a plug available in the tanks . it will work for 12volt even though it's designed for 110V. I have the same tanks on my 76 chief , it has been converted to a on demand pump , Still utilizing the steel tanks . I just got a replacement ShurFlo on demand 12V Pump from farm and fleet for $59.00 . Sea Hag

Yea, the switch is a culprit many times, I saw like ten compressors on the shelf at RV DR George and most if not all were tagged with notes saying the pumps would not stop running etc.
