View Full Version : Early shutoff

Hello Tom
I have a shoebox with 20 hrs. on it. I fill my scuba to 3500 p.s.i. from 2900 and I shut it down manually. It is a 4500 p.s.i. model. The last 2x it shut off at 3000 p.s.i. so I set the spring to shut off at a higher p.s.i, made no difference. What do you think is wrong, maybe a leak? Where is the most likely place it will start to leak?

Sounds like you have a very small leak. Most likely places are the fittings and the piston end of the cylinders. Use soapy water spray to find the leak. DO NOT use anything with ammonia in it.
