Triggers Each backup system has a trigger that activates the non electrical power source to begin operation. What are the different triggers? For battery powered and water powered backup sump pumps, water raises the float and the pump is activated into operation.
An automatic start standby generator is activated when the transfer switch senses a utility power interruption.
A portable generator becomes operational when a human starts it. Each of these triggers has advantages and disadvantages. See details for backup-sump-pump-float-switch-triggers. Go to top of page. |
Materials Used in Construction Thermoplastic: Outer casing is made of a hard, durable plastic.
Cast Iron and Stainless Steel: The outer casing and bolts are made of metal.
What are the advantages and disadvantages of the different materials? Thermoplastic weighs less and is cheaper.
Cast iron and stainless steel lasts a lifetime, weighs more and is constructed to handle heavy duty usage. This material is more expensive. See details for battery-back-up-sump-pump-construction.

Operational Capacity Backup sump pumps do not have the same operational capacity (pumping capacity) that primary submersible sump pumps do.See battery-backup-sump-pump-gallons-per-minute and water-powered-sump-pump-gallons-per-minute to compare pumping capacity, |
Dimensions of Backup Sump Pump and Pit
Each backup sump pump has unique measurements. A sump pit with an 18"diameter basin or larger provides the greatest flexibility in being able to fit a primary and a backup sump pump into the pit.
A tether float requires a larger diameter-based pit than a vertical float |
Size of Discharge Port Diameter
The size is either 1 ¼ or 1 ½ inches in diameter. Most backup pumps have an adapter to accommodate either size of PVC piping. What are the advantages and disadvantages of the different sizes? The capability to adapt to either a 1 ¼ or 1 ½ inch size PVC pipe is extremely beneficial. A size of 1 ½ inches is required to handle heavy volumes of water. |
Protection against Debris, Sludge, or Spherical Solids Backup pumps use screens to protect against particles.
Those with the additional protection of float cages are built so the cage bottom concaves causing particles to run off. |
Alarm Notification Each of the battery backup sump pump systems have audible alarms that sound when the battery is activated when backup sump system is running. The alarm also sounds when the battery is discharged. The Basement Watchdog Backup series also has an audible alarm when the battery fluid levels are low. Go to top of page. |
