Don't suck exhaust. Period. And check that gas level in motor. Also make sure your hose is free of all kinks and not getting stuck around underwater limbs and rocks.

I know there has to be some underwater tips, isn't the first atmosphere the most dangerous?

And don't stare straight into the nozzle with your face mask when it's running full blast just to see what's going on. LOL  |

All jokes aside, pressure is your worst enemy underwater. You have to make sure your air pressure is set for the depth that you want to go down.

I will try to put something together on this soon. Yes, the first "underwater atmosphere" is the most dangerous. The first 10 feet underwater is the most dangerous. Until then, NEVER HOLD YOUR BREATH while dredging.

I think some hookah systems are set for 40 psi while others are set for 100+ psi right?

From Keene: If a diver is working at depths of 33 feet or less, he will need only 30 to 40 pounds per square inch for optimum operation of his regulator.
Most Hookah compressors have a built in "pressure relief valve" which prevents excessive pressure from building up in the compressor head when the diver is only making a small "demand" on the compressor. This valve is usually preset at the factory at approximately 50 p.s.i., which will give the average diver at shallow depths enough air to operate his regulator while leaving enough pressure left over to allow for increased exertion.

Another from Keene:
If a diver is breathing at a normal rate (light exertion), the pressure relief valve will occasionally "pop off" and shoot out a burst of air. This is normal, as it prevents excess buildup of pressure in the compressor head. If a diver is breathing heavily and is under physical exertion, he will be demanding all of the volume and pressure that the compressor can deliver. In this case, the pressure relief valve will rarely, if ever discharge excess pressure or "pop off."

If I get out of the water, and stop breathing, and slow my motor down the pump never pops off and ceases the engine. That's why I need a new valve.

First off all of the air leaks need to be fixed in your system, there is no way your compressor is making enough air to activate the pop off valve with those leaks. |

LOL I know what ya mean. I need to find a local place that sells that pop off valve.

Bill in statesville can get those. I have to order one to. If you talk real nice he may sell you one off his in house dredge stock and order one to go back on his dredge. Just a thought
