Liberty Pumps SJ10 vs Wayne ESP25

The SJ10 SumpJet and Wayne ESP25 are similar backup pumps with similar flow rates but there are a few key differences. Unlike the SJ10 the ESP25 is battery powered and does not have the smart features and functionality so we recommend most people choose the SJ10 if they can use a water-powered backup.

Installation and Troubleshooting

This backup model is easy to install, even for non-professionals which is important in our rating system. Most people are able to install this pump in 20 to 30 minutes using a few basic tools from around the house. Since the SumpJet is so easy to set up and does not require electricity troubleshooting is easy, plus the pump has a good warranty in case anything goes wrong. Keep in mind this model does require a water source to operate with steady inlet water source pressure.

Why Choose the Liberty SJ10?

Still not sure if the Liberty Pumps SJ10 SumpJet is the right back up pump for your basement? We recommend this model for the following reasons:

  1. Easy to install
  2. Does not require a backup battery
  3. Drains 2 gallons of water for each 1 gallon used from municipal water intake
  4. Automatic activation when the primary pump fails
  5. Drains via normal 1 1/2″ discharge lines
