Asked by Peter August 23, 2020

Answer

No, you do have to prime it but it’s not a big deal; the access plug is right on top at the front of the unit

Which liquids are acceptable to use with this pump, other than water? Antifreeze? oils? fuels?

Asked by pumpster March 3, 2019

Answer

Liberty has designed and manufactured this pump with the intent that it be used by plumbers as a service tool for the transfer of water. As a plumber I most commonly use it to pump out leaking water heaters while doing water heater change outs. In addition it is capable of being used to pump glycol a specific type of nontoxic antifreeze into heating systems. However it should not be used to transfer any other types of antifreeze such as automobile antifreeze or any fuel or petroleum based products. It is NOT a fuel transfer pump.

Are the replacement brushes for this model available at home depot?

First, there is a brush kit for this unit. It is part number K00102. I have never been asked for it and it is not on HD.com however now that there has been a request I will add it. However if will take some time to get loaded. So if you may want to give me a call and I can tell you how to special order it through a store. Chris 978 651 3301
