<div id="yui_3_16_0_ym19_1_1555415066623_3494">Hi Alec, this might be a duplicate email. The pneumatic valves are in E3000, so your memory is intact ;-) I needed to experiment first with the solenoid valves first. Turns out I only need two valves. I like the pneumatic valves except for the plumbing, regulating and valving. I like how simple the solenoid valves are and making an oil filled enclosure would be pretty easy. I think I will delete two of the valves for safety for now and think about it some more.</div><div id="yui_3_16_0_ym19_1_1555415066623_3497">Hank</div><div id="yui_3_16_0_ym19_1_1555415066623_3498"><br clear="none"></div>

I said no, but that got me thinking, and I may not have realized that I was getting a air lock. Normally I dive Gamma heavy with no issues but at Lake Tahoe I was diving very close to neutral. The problem I was having at Lake Tahoe, was the sub leaning uncomfortable while submerging. I blame that on the weight of the sub and since the sub was light it could not push the water out of the vent lines casing a blockage. I like diving closer to neutral now so I installed 4 solenoid vent valves as an experiment. It has solved the problem completely. In fact I only need two valves to make it sink perfectly now. With all four valves open plus the two original valves open, the sub dives in 1 min and 30 seconds. Slow compared to Alec's sub but good for Gamma.</div><div><br clear="none"></div><div>My next challenge is to install a bigger port in E3000. First I am planning a proper poured concrete test pool in my new shop. Then I will dive E3000 a couple million times in the pool.
