I have installed my liquidator this past weekend. I did quite a bit of research here and searched the many threads loaded with advice.
I figured I would not add chlorine until I was comfortable with the set up and made sure all the bugs were out.
I had intended on a pump drain, heater drain set up...but ended up drilling and using saddle valves (another story).
Set up went well...no major issues.
I noticed, however, that I have very small bubbles forming in the tubing starting just past the adjustment valve. The liquidator setup from its output is: adjustment valve, flow meter, check valve, then pool pump suction. The bubbles form on the tubing and then eventually get swept away. Not enough to lose prime or anything like that...just constant "carbonation like" bubbles.
At first I thought I had a leak. But I really checked everything twice, used silicone, etc etc.
Here's the interesting observation. I opened the LQ flow valve to full flow. I took a pinch valve I had and started placing it on the tubing in various spots between the LQ and the suction saddle penetration. The bubbles formed downstream of wherever I put that pinch valve. Upstream tubing stayed clear.
So...I don't think I have a leak. I think the flow valve (or pinch valve) is creating a pressure drop and gasses are coming out of the solution.
So my question is: Is there any foundation for the LQ set up order (adj valve, flow mtr, check vlave)? Or can I change the order to flow meter, check valve, adjustment valve, pool pump suction? And have the adjustment valve close to the suction penetration? When I did that with the pinch valve, I got no bubbles or leaks and the supply tubing stayed clear.
