But one small design flaw, resulting in air bubbles coming into the overflow and loss of suction when the return pump goes out. This is because either 1. the black baffle on the tank overflow side is lower than the clear baffle on the bulkhead side, or 2. the volume sitting between the overflow side baffle is much smaller than the drain baffle. Anyways, it's not a problem if you run the airline into a working pump (will get rid of the air when the power goes back on), but it's a minor design flaw that can probably be easily fixed by increasing the volume on the tank overflow side. The other option is those u-tube ones, but air bubbles can easily get inside the tube without the airline outflow into a pump, so this is a much better option. Overall, great product.

All 3 leveling screw supports came unglued from the overflow. The bottom or back leveling screw is way too close the bulkhead and the screw head is too large because it rubs against the acrylic at the bottom of the overflow. I had to make the diameter of the screw head smaller. I re glued all 3 screw supports back on and repositioned them to function better. The intake grill was also cracked in several places so I glued the cracks to prevent further damage. It is working now but you shouldn't have to fix a brand new product. Not great quality and poorly designed.

as far as overflow boxes go, its a neat innovation. its quiet-that alone earned four stars.i was uneasy about the height of the water level, so i ground out the last baffle...doubled the flow. all-in-all, not a bad piece.

so util , well made , but I fixed the flow chamber, it was not well glued when it was made, had a fugue, but after that so well. it arrived so fast and well protected, surely I'll buy another one, thanks guys.

It's great if you dont mind having to check it a few times a day to make sure it doesn't lose its vacuum and stop working and overflow 15 gallons of water on the floor. It I do like it just have to get a aqua lifter pump for it.
