1/6 HP 1370GPH Portable Submersible Utility Pump Low Suction Electric Clean Pool Cover Basement Flood Drainage Water Transfer Pump Black

I bought this pump as it was advertised to be able to pump water down to a depth of 2 mm. I wanted it to use for draining my above ground pool if things had gone wrong over the winter and I needed to drain and refill the pool at the start of the season. I had a pump that could get the pool down to about 1″ of water, but that last 1″ can really leave you with a chore: 1.) You still have quite a lot of water to remove manually and, 2.) That remaining water is usually really rank with algae, winter debris, and whatever. So it has to come out or your just going to be dealing with last year’s problems again soon.So, I decided to spend the $70 bucks and I got myself the Extraup submersible. I’m glad I did. It takes a bit of coaching to get the bottom of a pool liner nearly dry (debris clogging, uneven bottom even if you think it is perfectly flat…) but, when I was done I could have sponge dried what was left in an 18′ round , above -ground pool into a 2 gallon pail in short order. Like I said, it is not a set it and forget it type of operation to get the pool dry, but it is much less labor intensive than any other method I have used.One issue you will have to deal with, as I did, is the fact that the submersible will instantly suck onto the pool liner and you will lose all flow. I’ll have to think of something better for the years to come, but this year I just jammed anything I could find that was 1/8 – 1/4″ thick under the pump. The skimmer lid seemed to work the best, but it would be nice if the pump came with something that would keep the base of the pump from direct contact with the liner.Overall, I’m very pleased. The pump drained my liner enough to make liner patching very easy and effective. If they would provide some form of 2mm stand-off below the pump, then this system would be perfect.Jimmy
