compressor leaking back through

i have a thomas compressor and its leaking air back through really bad it will build like 80psi then its just starts leaking it all back out whats wrong? can i fix it?

you need a check valve

sounds like u have worn ur ring down that happened to my friends

If a check valve won't fix it, the compressor needs rebuilt or replaced.

All 4 of my Thomas compressors started doing the same, Just use a check valve. The SMC ones are great, let me know if you don't find one somewhere else.

smc has good check valves there like 20 bucks from suicide doors or street beat customs has push in check valves that look like unions. but i would get a new compressor anyways only because its only going to get worse.

ok thanks guys i was just needing it to hold up for a month or two ima get a AZ when i get the cash.

what compressor is it? i had a 315 and the head cracked. the reed valve could be bad to.

we have both parker and smc check valves. the smc is a diaphram check valve and after time might need to be rebuilt. a parker is all brass, wont crack and is a ball check. never hardly ever goes bad. i have them in 1/8" as well if that is how small your compressor is.

yeah its a thomas 315 how do you use check valves?
