Rola-Chem M-3000-1 Pool Sentry

What a life saving device this is. Used it for my pool and now I never have to top up. Thinking of getting one for my koi pond. Highly recommend this.

This is our third purchase of this pool filler. Its easy to set up and works great, but it sits in the sun all day so it's not surprising that the plastic starts deteriorating after 5-6 years. I think any pool filler would have a similar life span, so we are sticking with what we know works.

The media could not be loaded.  Muy buena opción para rellenar de forma automática la alberca, equipo pequeño y apropiado. No he tenido ningún problema con el uso, 100% recomendado.

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.

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.

I can’t believe how well this small device works. For years, we’ve had to drag out the hose across our patio several times a week to fill up our pool from heat evaporation. Then we had to remember to turn off the hose so the pool wouldn’t overfill. To save all of that work and tripping hazard, we installed this simple device and connected it to an underground water line. It uses an internal bobber that you can set at any height, and it automatically turns the water on when the bobber drops, and automatically turns the water off when it rises to the top where you set it. You can basically set it, and forget it. It is the best pool purchase for the money!!
