My DH installed the 8-gal Liquidator over the weekend, with the 3/8" upgrade from Bruce/Sal.
We have a 2-speed pump that runs during the day for 2 hours on high then 6 hours on low.
I tinkered with LQ after install and have been testing the water for the last couple days and its definitely putting chlorine in the pool, but we have air in the lines that I can't seem to make go away.
After LQ was installed, it leaked a bit a both ends, plus we could hear a slight hiss from the drilled hole with clamp just before the pump, so we adjusted the clamps at both ends a bit and that seemed to take care of the leaks and hissy noise. But the air is still in the lines. When I turn the flow meter all the way up to 5 and the 2-speed pump is on high, then they disappear for the most part though not entirely. When the flow meter is turned to 2 and the pump is on low, the whole tube gets filled with air -- both tubes from the IN and OUT, if I recall correctly. I noticed this at the end of the day yesterday after it had been running on low all afternoon.
Is this normal? If not, does this hurt the pump? Why does this happen? And how can I purge the air from the lines once and for all?
