## Questions & Answers

**Q: hwhat do you adjust to keep it from overfilling?**
A: The float, which rises and falls with the level of the pool, has a long plastic stem which can be twisted, by hand, clockwise or counter CW to adjust the level.

**Q: Will this work on an above ground pool?**
A: Depends on the width of the lip of your above-ground pool. It isn't designed for above-grounds but, could potentially work with a wide space to set the weighted down base upon.

**Q: I see that this is metal,  can it be used in a salt water pool?**
A: This is used on our salt water pool and has stood the test of time.  Our neighbors purchased it for their salt water pool as well.

**Q: Is there an extension collar?**
A: No.  Your hose is the extension on top and if you need it higher you can put it on top of a brick or mat.

    This is my third one in 15 years "not bad"
  

*by D***E on Reviewed in the United States on 11 October 2022*

Can't beleive any pool builder would build a pool that would require you to use a water hose to keep your pool filled on a regular basis, duh!  But this little guy is a true savior that removes the headache of constantly monitoring and filling the pool not to mention possible over filling.  I live in Arizona and the summers here are hot so evaperation is constant, but not a problem with this simple yet effective gadget.  Works on the same principle as your toilet tank filler.  I can just imagine the light that went off in some persons head that figured this system out.  It's takes 5 mins to put together, I do recommend connecting a good quality dependalbe hose that can endure the elements of all day sun exposure like the "Zero-G" hose or the "RV/Marine white/blue hose ", which iI have used for years now, both great products.  Since the hose stretches from the spigot to the edge of the pool, You may want to consider putting some orange paint or tape on the hose so people see it and don't trip over it.  Note: YOU MUST PUT SOME PLUMBERS TAPE AROUND THE "THREATED" PARTS (2 OF THEM; ONE ON THE HOSE AND ONE ON THE UNIT)  OR YOU WILL MOST LIKELY HAVE A LEAK!  The plumber tape takes care of that issue perfectly.  Now turn the water on and it should start to put water into the pool.  With the pool water level already filled to the mid point of the skimmer openning, I used some tweezers to grab the hard to get to white stem that adjusts the shut-off point by pulling it up and turning it counter clockwise until it shut off.  I did put some farely good size rocks inside the box area to weight it down.  Lastly, I make sure my hose is straight so theres no tension to cause problems. that's it check it once or twice to make sure no leaks and filling correctly, then forget about it (well maybe check it from time to time)!  I can't say enough how it has taken the stress and worry out of whether the pool has enough water 24/7 especially if you aren't home for a few days, because if the water level gets lower than the skimmer opening, your pump will run dry and burn it up.  I saw another post on here that gave it a terrible review I just can't beleive given my experience which this product which includes it hasn't been abused by kids, dogs, mowers etc.

    Works perfectly so far.
  

*by L***. on Reviewed in Canada on 29 August 2019*

We have a small leak in the liner of our inground pool at our cottage, so we purchased this to keep the water level where it is supposed to be when we are not there to monitor it.  It's been nearly a month and seems to be working perfectly.
