I see a lot of threads about cover pumps, but I have a SmartMesh cover, and it was recommended by the installer to put a sump pump in the pool to automatically drop water level if it gets too high... but, if I sit it on my swimout and adjust the float switch to keep the level where I want it, the pump and discharge line will freeze and the motor will be toast. If I put it in deep water and manually turn it on and off when I need to drain water, the discharge line will still freeze and I wont be able to pump when frozen. Other than checking it every month and dropping the pump in and taking it out each time, any better way to do this?
It is also a pain in the neck to unhook and re-hook 5-6 cover straps just to check the water level. I would love to find a device that will detect water level... I was even thinking of an IR wireless camera under the cover. Anything to make this easier.
The main thing I am trying to prevent is the water getting to skimmer height, or shelf height. I have 3 color cascade bubbler niches on my shelf and if water gets into them it will freeze. I put foam in the niches but I doubt that will keep things from getting messed up if it freezes.
I dropped the water level to 16" below coping since I was told that is what Merlin requires... but the installer told be it did not matter... just below the skimmer would have been fine. They said the Merlin cover does not need any support from the water. There is no pillow or support under the cover. Is this correct?
