Shop Hydrostatic testing

[DavidR8]

Wondering if anyone has had a compressor tank hydrostatic tested.
I have an older Speedaire 20 gallon compressor that I bought used several years back. I've used it to spray with my HVLP gun but not much else.
Thinking of getting it tested for peace of mind so it doesn't grenade in my shop.

Several guys have done this on youtube to 2X the reated pressure. Thye used a pressure gauge and a grease gun, with everything filed with water, of course.

Found a pressure test pump. I think I'll give it a go.

Why not just a cheap grease gun? Usually outputs between 2000 and 5000 psi. Cobble a zerk into the appropriate fitting.

No reason other than this will be useful for pressure testing a steam boiler that I’d like to build.

Or you could play with the new lathe.

I should do this too. I have had my compressor for quit a long time. Bought it new a way back and used it off and on ever since. I have never noticed any rust in the water when drained. It actually doesn't make much water, just a bit of oil in the air when I drain it. It used to drip oil from the bottom of the tank and it took me a while to figure out where it was coming from. Meanwhile it had me concerned thinking there may be tiny hole somewhere in the tank. I finally found it, the sight gauge in the compressor crankcase was slightly loose and the oil was seeping out and down to the bottom of the tank.

Pressure washer works as well
