    • High-quality pool filler eliminates annoying routine
Review Image by Robert B AZ Robert B AZ
Review Image by Robert B AZ Robert B AZ
The annoying routine mentioned in the headline is the frequent monitoring of the pool water level and having to fill it manually with a garden hose. As those of you who don't have a built-in automatic filler know, two undesirable conditions exist in addition to the obvious annoyance factor. First, if you neglect to fill the pool, the water level will eventually drop below the skimmer and the pump will draw air, losing prime. That's a real problem here in Phoenix where summer evaporation robs us of about an inch of surface level each week. Second, if you forget you have the hose running in the pool it will overflow and you'll end up with a flood and a higher water bill. This simple, but well-made device solves all that. It operates just like a toilet tank fill valve and it has an adjustable bracket so it will work on just about any in-ground pool or spa. We've only had ours a couple months but it has been working flawlessly so far. I installed a high-quality, double-ball valve wye shut-off on the supply hose bib and used a braided stainless steel washing machine connector with a brass adapter to attach it to the filler's supplied connector. The stainless steel connector is essential here in the desert because a typical vinyl or even rubber garden hose that is under constant pressure is prone to sunburn and eventual bursting. Since the filler gradually meters water into the pool as needed, keeping the supply wide open is not necessary. Ours is kept at less than fifty percent open which will extend the life of the hoses and will serve to mitigate the loss of water and potential damage in the unlikely event of a supply hose failure. I 100% recommend you purchase this product if you are tired of dragging a hose to your pool and you want to stop having to impose upon neighbors or family members to do so while you are away. ... show more

    • Service after the Sale
I also purchased a water pressure reduction valve to reduce psi to 25. It was the plastic version of a name brand mfg. Upon receiving the pool leveler, I connected the pressure reduction valve to the supply hose and then to the stainless steel connector that came with the leveler. When the pool water reached the desired level, the leveler continues to seep water, not shutting off the supply hose. I contacted the seller and we tried several fixes, which did not solve the problem. He then sent me a brass pressure reduction valve from the same name brand mfg that produced the plastic one I had purchased. This corrected the seepage issue and the unit is operating as designed. 5 stars on the product and 10 stars for the seller for service after the sale! ... show more

    • The best in its class!
This thing is a game-changer. A former pool maintenance person convinced us to get one of the run-of-the-mill versions of these, but our pool has taller coping and walls on three sides so it was always cluttering the entrance to the pool. I got one of these with the add-on extender (also available on Amazon) and was able to put this in a more discreet and less cluttered location. It's much more functional and versatile than anything else like it on the market. You're wasting your time with all the other ones. This is worth every nickel—since pennies have been retired. ... show more

    • Excellent and easy to use product. Highly recommend.
Review Image by J. Engelhardt J. Engelhardt
Outstanding product/solution for maintaining pool water level. Mount is heavy and sturdy. Easy to connect to garden hose and setup on pool edge. No issues with “noise” from unit while adding water. Sometimes hear suction noise when pool has waves (to be expected). One improvement that I’d love to see would be a cable/snap system that allows the garden hose to be nested parallel to the ground.. versus the hose bents due to the metal connector hose provided by the vendor. ... show more

    • Works well, the float is better than on the cheaper models but slightly harder to adjust.
This is my third auto-fill device. So far it's working better than the previous two (which were the white plasitc ones that are common). My only two issues are that: (1) there is some rust at the exposed connection with the supplied metal braided hose (after six months); and (2) because the valve closes slowly as the water level raises (meaning that the water flow slows down as the float approaches the cut-off point instead of just stopping at that point), this one seems to run much more frequently but at a very slow flow. Also, and this is not a negative for me, but if you want to adjust the water level, you've got to remove the device from the pool and turn two srewes to raise or lower the bottom portion with the float in it. That's more difficult than in the cheaper models where you can just turn the long plastic screw that the float rides on. ... show more

    • Super easy, super simple, well-made
Super easy, super simple. We are fortunate to have reasonable water pressure and a flat pool surround. I put a couple of bricks on top of the weighted support so that our Polaris pool cleaner wouldn't bump into the leveler and knock it loose. That never happened. We went away for 2 weeks and the water level was kept perfectly constant. Highly recommend this well made and simple solution. ... show more
