How to put a drain valve on air compressor? Hi Bill, I’ve got a compressor that doesn’t have a drain, can you please give me some advice how i could add a drain valve on my compressor? Thanks
Regards,

RF, it is odd to have a compressor tank without a drain, as every time a compressor runs, it’s pumping water into the tank too. Be good if you would upload a photo of the tank for all to see.
Assuming it is a bona fide air tank that you have, then the process would be, with the tank empty of air completely of course…
- acquire the tank drain
Basic air compressor tank drain
- drill a 1/4-3/8″ hole into the tank at the lowest spot on the tank
- figure out what the male thread size is on the drain
- weld a nut of the appropriate size to the exterior of the tank, over the hole (the weld must be pressure resistant up to the tank burst pressure – not a job for an amateur
- thread the drain into the nut thread using an appropriate sealant
Or, get a compressor tank that is already so equipped and relocated your pump to the new tank.
Good luck. Let us know how it turns out, will you?
