How long will Hydropump operate during a power failure?
A. There are many factors that affect this answer. Refer to the Hydropump page for a chart of pumping times. Generally, 2 – 5 days on average, depending on how often it needs to run, the head pressure it is pumping against, the discharge piping, etc. Under continuous running, which we define as a 30 second run every 2 minutes, starting with a fully charged battery, and pumping against 9 feet of head pressure, the RH1400, DH900, and DH1800 will run 12 or more hours. An extra battery can be added to the RH1400, DH900, or DH1800 using our DBC Kit. This doubles the pumping times.
