Leak at pressure switch

[iceman510]

My Sanborn 60 gallon compressor bleeds pressure down when sitting (drops to about 55-60 psi). I sprayed soapy water on the lower part of the pressure switch where the hiss was coming from. It appeared to bubble at the joint between the manifold an the electrical portion of the switch.

Is there a diaphragm there or something that might tear or leak? Do I need to replace the pressure switch? I will try and get a picture to post.

Thanks.

There is a diaphragm that can leak. Replacement is up to you. If it's bad enough or annoying to you then replace

If it looks like it's internal meaning that diaphram then you will need to replace it. Do look around the internet for replacement before plunking down bigger parts for something with the dreaded PN. Everything I have gotten for my Campbell Hausfield I got from Ebay or Amazon as direct fit replacements. Why not CH is quasi junk so you are getting junk anyways right so get it as cheap as you can I always say. Pretty much half price. If you can't find it there then look at Jacks Small Engine or E replacent parts .com . They will cost more but will have them.
It's been a while and I'm reaching here but the one I got for my Junk was a well water tank switch that worked perfectly. You have to dig around and see what matches thats all. Much of this stuff is interchangeable.
