    1st stage leak

    Hey guys, I have a older model SeaQuest 1st stage reg that has a slight leak. I put it on a tank, and checked the spg. It went down maybe one PSI after a few hours. Do you guys know if it is made to have a slight stream of bubbles when under water???

    if it were made to have a stream of bubbles underwater there would be a spot on the first stage with a rubberish cover over a spot which kinda looks like a hose would go.


    that being said 1 psi over a few hours can be a small bit from a 2nd stage.....temp change in the bottle....etc.... but doesn't sound like much of a leak.......put it under water and see if it bubbles......if it does, get it serviced.....i think aqua lung can look after them now?

    It sounds like the regulator hasn't been serviced in awhile and air is moving past a small 'dry' area on an o-ring.

    It's time for a service.

    Take a soda bottle, fill it up with a soap/water mixture, put a SMALL hole in the top, and stream the soapy water on all the seals to find the leak. Just watch for bubbles!

    I'm also confused, you put the 1st stage and SPG straight onto the tank without a 2nd stage? Good luck trying to get it off!
