Co2 paintball tank not lasting long enough? 20oz bottle

[new to the scene]

K just set up a co2 paintball on a 37 gal. I used a watts valve with Teflon tape but I can't seem to keep pressure on. The co2 comes out around 2-3 bps. If I used any less pressure the water pushes it back up the tube and no bubbles. The co2 is only lasting a week if that. My question is if this is just how much a 20oz bottle will last

This question I am looking forward to hear answered since I plan on doing the same with a 20oz paintball bottle for my 20gal.

Hopefully someone knows!

Is it leaking somewhere? Put the whole deal into a bucket of water with it 'turned on'. Plug the end of the CO2 line with your thumb and look for bubbles.

It should last longer than that.

Rather than submerging the whole rig, you can mix up some soapy water and paint it onto all the connections using a paint brush or pastry brush. It will bubble anywhere there are leaks.

I did find a leak tightened [it] and put some sealant around it well see if it lasts
