    • Best DIY Pool Auto-Fill—Better Than Built-In Systems
Review Image by Doctor Doan
This is hands down the best automatic pool filler I’ve used. I’ve had built-in auto-fill systems installed by pool builders in California, and they cost significantly more—yet this simple device performs just as well (if not better) at a fraction of the price. In Florida, I learned that built-in autofill systems can actually develop algae buildup and clogging issues due to humidity and stagnant water inside the plumbing. That’s what led me to look for a DIY external solution, and after researching multiple options, I landed on the Fill-O-Matic—and I’m glad I did. Pros: • Works exactly as advertised – keeps my pool water at a perfectly consistent level • Super easy setup – just connect it to a garden hose and you’re done • Reliable float system – no fluctuations, no babysitting • Cost-effective compared to builder-installed systems Cons: • Requires water pressure below 60 PSI, so you’ll need a pressure regulator • Not a big deal—I picked one up for about $14 • It’s not built-in, so it sits outside the pool (purely aesthetic concern) Tips: • Buy a pressure regulator (under 60 PSI) to protect the unit and ensure proper function • Use brick, coping, or pavers (like I did in my photo) to weigh it down and make it blend into your pool area—it actually ends up looking pretty clean and intentional ... show more

    • High-quality pool filler eliminates annoying routine
Review Image by Robert B AZ
Review Image by 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

    • 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
