Water in tank?

Guy’s, how often should one empty out any water collected in one’s tank? I just stripped down my old 3litre tank and there woz about a table spoon of rusty water In it, after 3years of use.

i empty mine once every two weeks

i never empty mine but my tank is aluminum

Whenever I remember. The more The compressor is on, the more I tend to empty it. at least once a month

Cheers dudes!!!

Next question, do you do it with some air in the tank, to help blow it out or with the tank void of air?

Use the air that’s already in the tank.
You do have a drain cock installed - yes?

Cool, yeah I got a Drain cock on the bottom of my tank. Cheers Lance

What to do if your tank does not have a Drain cock ???

?? i’d like an answer to that too. why do they even make tanks w/o drains in them.

i have a 5 gal 4 port tank. it has no drain at the bottom. so i guess once a month or so i have to unmount it and tilt it up and drain the water? if so my tank will be for sale soon.

would it be posible to drill a 1/8th" hole in the bottom of the tank and tap/seal it? seems unlikely cause i doubt the metal if very thick. but i dont want to weld on it cause my tank is chrome…

i have access to a full machine shop. but my main wory is the chrome blueing or chipping. i guess if all else fails i can just powdercoat it.
