Customer Questions & Answers

Why does it show on this site for this model number to pump 110 gph, and several other sites I have checked, shows it pumps at 80 gpm?

Asked by: zip
Chris. GPH is gallons per hour. GPM is gallons per minute. The question was why on this site is it shown as gph, and other sites show it as gpm. With the gph being only 30 gallons more by the hour than by the minute. The question is not dealing with any heights, only the designated flow.

Asked by: Hamberger
Yes contrary to what has been posted they do make this series in 208-230 volts. It is catalog number 509217 It is not listed on Home because it is so uncommon but it can be special ordered for you by a Home Depot store. It will be a factory order.

Does this device have a floater attached?

We currently have one, but it is not always triggered by the floater and water overflows.
Asked by: BB
This pump does not come with a float switch. It is designed to be used in connection with a float switch or a float switch panel. When setting up a sewage ejection system the choice of the control system and the setting of the floats is one of the most critical things in making sure the system works well. Float switches are available that work at different angles and making sure they a positioned so that they always take a proper path as they float up is very important. If they snag because they are positioned with two much slack often becomes a problem. Some systems will apply a number of floats and a switch panel. In this situation you have a on float, off float and alarm float. By using this technique you can keep the pump constantly submerged which increases its life.
