Rola-chem M-3000-1 Pool Sentry

Description:

  • Automatically maintains water levels
  • Attaches to heavy duty re-enforced garden hose
  • Protects pump against burnout
  • Never overfills the pool
  • No tools required
  • Material Type: Metal
  • THE POOL SENTRY is used to maintain the water level of a pool, spa or pond automatically and unattended. When the Pool Sentry is removed from the box, it is easily assembled by threading the fill tube into the float valve. Snap the fill tube and float valve into the base and fill the base with small rocks or pea gravel. Next, snap the top cover onto the base and attach the garden hose (not included). Finally, adjust the float to the desired position. The supply water stays on at all times when the Pool Sentry is in the pool. As the float drops, the water turns on. When the float reaches its set height, the water shuts off. The customer can adjust the float to any desired level, usually a point halfway on the tile line or skimmer. Because the hose is under constant water pressure, it is essential that the customer uses a heavy-duty, reinforced hose. A flyer in each box offers customers an aftermarket hose. It is rated to 200 psi working pressure and 750 psi burst strength. The Pool Sentry works with a pool water level that is 2 to 8" below the pool deck surface.

    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.

    The float is not free floating. It sticks. When the float sticks when the pool water level drops it can burn out your pool pump costing a lot of money to replace. This was a brand new item installed completely level and according to instructions. No matter what I tried the float would stick so I have no alternative but to return this item.UpdateCancelled my return and changed my review to 4 stars. When taking the item apart to return it I removed the float housing and pushed the float up and down and it was still sticking badly however as I manipulated the float the tube in the float housing suddenly clicked and I realized that the tube was not seated all the way in. After it clicked and seated itself the float became free floating and worked as intended. So before connecting the float housing to the main body be sure to check that the float tube is seated correctly and check that the float is free flooring.

    1.0 out of 5 stars The Pool Sentry leaks

    D.J.F. · May 4, 2025

    The Pool Sentry auto pool leveler appears like a good product when reading about it's capabilities. I use this product while away from home on extended vacations. My hose bib is 100 feet away from where I position the auto filler by my pool. This purchase was a replacement of an old filler.When I connected an existing hose that I have used in the past, the auto filler leaked at the hose connection. After adding plumbers tape and doing additional tightening of the connection, it still leaked. I presumed that the hose that I was using needed replacement and $90 later I had all brand new parts. Unfortunately the problem was not the hose but the cheap connector on the Pool Sentry. After connecting the new hose to the Pool Sentry, it continued to leak on to my cool deck which I knew would cause staining in the long term. I returned the Pool Sentry and replaced it with a similar product. If you opt for the Pool Sentry note the notification on Bolo advising customers that the Pool Sentry is a frequently returned item. Also don't assume as I did that the male connecter portion of your hose is what is causing the leak. It it the connector in the Pool Sentry.

    5.0 out of 5 stars I love this thing.

    Before I had this I used a timer on the hose. It was pretty cheaply made, leaked and I never really trusted it. It was a standard, mechanical hose timer that worked like a wind-up egg timer. I also looked a battery operated, programmable ones but never ended up getting one because I found this. It works the same way your toilet float does. There is a float on a stem that hangs over the side of the pool and can be adjusted for depth. Once the float raises to that point, the water cuts off. When the water level drops, the float drops with it and the valve opens again to allow more water to flow into the pool. It is such a simple concept that it is extremely reliable. All you have to do is make sure that over time the stem doesn't develop calcifications that might cause the float to jam. Other than that, it really just works. I've been using mine for months now and have had no problems whatsoever. Before this, every time I went out of town I worried that my pool level would drop and my pump would be sucking air. Not a problem any more. I highly recommend this product.

    5.0 out of 5 stars No more running a hose to the pool

    Prior to this is had to use a hose pipe to top up the pool. Occasionally I forgot and the pool overflowed. Now I don’t have to worry and I can go on vacation without asking my neighbor to top up the pool

    Highly recommend this.

    Connections Important

    B.L. · April 7, 2023

    The product is basic, so easy to fit and use. The only downfall with it is the connections, they aren't included unless you are in America. Tried purchasing a reinforced water pipe (Caravan) so it could handle the constant mains water pressure but the snap connection is the weakest link and only lasted a couple of days before bursting. If you aren't home, this water will keep running until you get home (sorry if you are overseas like I was) or if a friendly neighbour will notice the wastage and turn the tap off for you. I will be trying "Hoselink" once I return home as these seem to be the best product to use for hose connections that are under constant pressure.

    Works perfectly so far.

    L.H. · August 29, 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.

    A Better Filler Upper

    C. · June 4, 2018

    I have a slow leak in my pool, the water level drops around 1/2" to an inch per day, the Rola-Chem M-3000 does the fill up job for me. Great gadget, a little expensive but for me it was worth the money.

    It works

    b.n. · August 3, 2022

    Looks kind of fragile but it has not failed. Difficult to get it set the first time but once it is set it does the job. I would buy it again.
