I just replaced my ancient HASA Liquidator with the new HASA Liquid Feeder.
After installing the unit and starting things up, I noticed that both floats would stick in place as the water level went up and down and then "pop" loose. The result was that the flow on the out/suction side would start and stop.
After a lot of difficulty I finally reached a human at HASA who took a message. I was contacted by a consultant that works on the Liquid Feeder product. Apparently this is a known problem, because he immediately offered to send replacements for the purple "saddles" that the float hinge pins snap into. He said that the holes that the hinge pins go into needed to be very slightly expanded. He recommended that I not try to expand the holes myself. The new saddles seem to have fixed the issue.
I had to load up the threads on one of the new saddles with lots of Teflon tape in order to get it to stay in the proper position.
This next issue is probably unique to my installation, but the information might be of use to somebody else.
My pump is 3 feet above my pool and has very little head left. It can barely prime.
The Liquid Feeder has a larger footprint than the Liquidator, so I had to move it to a different location on my equipment pad. Using tie wraps I ran the out/suction line very neatly up to and along the piping coming out of my sand filter and over to the pump basket. Unfortunately that routed the out/suction tubing higher than the water level in the Liquid Feeder and the pump was unable to establish any flow. As soon as I re-routed the tubing down to ground level, below the level of the water in the Liquid Feeder, the system worked fine.
Notes - I moved the old flowmeter from the Liquidator to the Liquid Feeder. I plumbed in a tee, a short length of tubing and a valve between the outlet from the Liquid Feeder and the spinner. This will let me suck a dilute (5:1, always add acid to water when diluting) acid mixture out of a jug in order to periodically clean out the tubing and flowmeter. (I learned several years ago that this is the cleaning method used by a HASA technician.)
