    NOTE: These pumps are designed to operate below water level out of the water. If you need to operate the pump above water level, you will a Priming Pot/Strainer Basket and a Check valve. The check valve will get installed at the intake to allow for the water to stay in the intake line and create a siphon effect as these pumps do not pull water.

    Deserves a repeat buy My previous Sequence 1000 had worked for 18 years, 24/7, until finally it developed a leak. As pumps go, that is an excellent performance, and I was happy to buy the same model again. My only wish is that it were a little cheaper. But I'm not complaining.
