Frequently Asked Questions

Q. "Is there anything else I should know about this back up pump?"
A. Make sure to follow all of the manufacturer's instructions and directions by performing the proper maintenance and inspections to ensure that you are fully protected from flooding - this is ever-so-important with (man-made) safety devices as they will eventually fail. Proper installation, inspections, and maintenance can go a long way toward extending the life of your pump and providing optimal flood protection.

Q. "What does 'heads' mean in terms of pump performance?"
A. Since sump pumps are used in basements or underground areas, the water must usually be pumped above ground to be disposed of properly. Generally, pump performance is measured by how many gallons of water the pump can move to a certain height. The 'head' is how high the water will be pumped. For example, using the above chart, when the water pressure is at 20 PSI this pump can pump 11 gallons of water four feet high in one minute. When the water pressure reaches 60 PSI, the pump can move 19.8 gallons of water per minute up to a height of four feet.


Please note: While we strive to ensure every product we label as "Made in the USA" really is 100% made in the USA, it is also important to understand that sometimes manufacturers make changes to their products, or for various reasons may receive components or materials that they would normally purchase domestically from an overseas supplier - and they don't necessarily let distributors (like us!) know that they've changed something about the product or where it is manufactured.

If you receive a product that PlumbingSupply.com® says is "Made in the USA" and the product states it was manufactured elsewhere, please contact us. We will happily replace or refund your purchase to your satisfaction.
