Hasa Pool Liquidator C201 Chlorinator, 8 Gallon, 3/8" UPGRADED

The shipping time from CA to OH took longer than a week.The product is relatively easy to install. The build qualiy seems to be excellent.I use flexible hoses to and from my above-ground pool so I bought PVC pipe and fittings so I could fabricate extentions to the pump and filter so that I would have a place to drill the 3/8" holes for the input and output for the Liquidator.My pool reading was 5.5 ppm on a Sunday when I first started the Liquidator. I could not test again until Saturday and it was a 1.5 ppm reading by then. My pump is 2-speed and I had it set on "slow" speed for the week. The provided vacuum meter read about 1.0. The Liquidator's valve was set to 100% open. To boost the chlorine level, I switched the pump to "fast" speed overnight and vacuum meter read about 6.0. The chlorine reading jumped to 21.5 ppm by the morning...oops...that was not intended.I did purchase the Hayward PVC Needle Valve for the setup but I have not installed it yet so I am currently using the valve provided by the manufacturer.The rate of chlorine is too low on the "slow" pump speed and too high on the "fast" pump speed. Next, I will need to use the "fast" pump speed with the pump on a timer and turn down the valve until I can strike the right balance between right number of hours of filtering and rate of added chlorine.Bottom-line - so far I am very happy with my purchase.

I waited until the end of the pool season to submit my review, i installed this item and ran it the entire season (over 4 months now, and i have a plaster pool approx 35,000 gallons). I found it to be very ineffective at delivering chlorine with any precision. its passive delivery system means that as your filter gets dirty between cleanings the system delivers less and less chlorine over the same time span. to the point where when I'm nearing a filter backwash, this system is almost delivering 0 FC. then i will clean the filter and the liquidator tank can empty itself in a day or 2, over chlorinating the pool. if you are considering this product i highly recommend adding liquid chlorine by hand manually to the pool every day as its actually less work (because you need to pur chlorine into the liquidator every day or 2 anyway) and will probably be more precise.additionally, i also kept my pool chemistry at optimum levels (TA, PH, CA, CYA) and despite this i now have very significant white chalking buildup in the liquidator lineset, i would need to replace it all if i were going to run this system next year. (which i will not)

In my opinion, the value for your money simply isn't there given that this is a medium sized plastic bin with a couple of float valves, some tubing, cheap flow meter and even cheaper check and ball valves. I find it a little irritating that Hasa sells this at a ridiculous price in hopes that you fill it full of their liquid chlorine. The 3/8" upgrade is kind of a joke since the ball and check valves they supply slide into the tubing restricting the flow to an unusable rate below 3 on the flow meter. This may not be a problem for you if you have enough back pressure in your return line that feeds the "in" side of the chlorine bin. One interesting thing to note is that the instructions tell you in the trouble shooting section that you can connect the "in" hose to between the pump and the filter if you don't have enough back pressure to supply the chlorine bin with the needed flow rate, but you probably won't read that part until you have already drilled a hole to mount it after the filter. Furthermore, you don't need to do that if you simply replace the supplied check valves (grey in photo) with push connect valves (white in photo) where the tubing slides into the valves, those won't restrict flow. Those modifications worked for me but cost an additional 40 bucks. I have only been running it a couple days since making the modifications to increase the flow so I don't know how the unit actually performs with respect to supplying an adequate rate of chlorine to the pool.

Instructions are weak at best. The "in" side with filtered water seems to work okay (except the float gets stuck); however, the "out" side has the following list of problems. The provided back flow preventers clog quickly as well as the flow meter. Everything needs to be soaked in vinegar or other weak acid at least once a month. This includes the floats which stick after about 6 to 8 weeks and plugged by sediments. The 3/8" kit works okay but the back flow preventers clog even sooner than the 1/4" original supply. In short it has almost taken daily maintenance after 2 to 4 weeks of operation. The "out" float broke off after about 8 weeks. Also, I have only used HASA chlorine because that is what my preferred pool supply place stocks.I have tried upgrading the system to 1/2" ID tube, spring back blow preventer, and sediment screen but still have problems. I will try to obtaining two sets of everything to allow for swapping out one set while acid washing the recently used set. Installing a set of shutoff valves is mandatory because of the need to frequently service/maintain the components.As of now, I would not purchase the 3/8" upgrade kit since these valves clog and stick in the open position allowing for back-flow before blocked completely.If I get this to work consistently where it requires maintenance beyond filling chlorine no more than once a month, I'll provide photos and a description of what I got to work. If it is still more work than it is worth, I'll provide that too.
