What To Consider When Selecting The Best Sump Pump Battery Backup
Dependability and longevity are among the best considerations when selecting a sump pump battery backup. When searching for a backup sump pump, how rapidly it can eliminate water and the length of time it can operate before the electric battery runs down are essential features.
Material Of The Sump Pump Battery Backup
Battery backup sump pumps often feature housings made from industrial thermoplastic, stainless steel, or some other waterproof materials made to withstand corrosion. The housing must be sealed to avoid water from getting inside the pump’s parts.
Pedestal Vs. Submersible
Like primary sump most pumps, an electric battery backup sump pump could be one of two types:
Submersible: A submersible unit rests within the sump pit, that is, in the basement floor. When water goes into the pit, the warm level starts to increase, and once the water reaches a certain level, the pump kicks onto pump water on the surface.
Pedestal: The pumping engine of any pedestal sump pump rests atop a column, and the base of the column sits within the sump pit. The column is around two to three feet high, so the pump motor rests above the floor. Since the pump rests above the water, it should be moisture resistant, although not completely waterproof like a submersible pump.
Battery & Runtime Of Sump Pump Battery Backup
Battery backup sump pumps operate on 12-volt, acid-free batteries. Some manufacturers advise a battery that is marine rated, which could mean it will withstand moisture better than a regular 12-volt battery power. A 12-volt battery’s power can vary from 40-amp hours to 80-amp hours or more, with 75 amp hours the most common. The bigger the amp-hours, the better the battery power and the longer the backup pump will go. How rapidly a battery runs down is determined by how much water enters the sump pit and how frequently the pump should cycle to pour it out.
For instance, if a backup sump pump cycles after every four minutes & most pumps out 1.5 gallons with every cycle, a 40-amp-hour electric battery could last 32 hours, while a 120-amp-hour battery may last better than 96 hours. Nevertheless, in case the pump cycles each second, the 40-amp-hour battery’s runtime will drop to around eight hours, and also, the 120-amp-hour battery will last better than 24 hours.
Yet another aspect enters the scene: After four or maybe five years, a 12-volt battery will begin to shed several of its power to support a charge. What this means is that an old battery is going to have much less runtime. Deciding on a strong battery—and changing that battery every four or five years—will be the better option for maintaining the basement free from unnecessary water.
Gallons Per Minute
Also referred to as its capacity, a backup sump pump’s gallon-per-hour (GPH) rate estimates the optimum amount of gallons it can pour out within one hour when the power supply is fully charged. This quantity generally appears on the pump’s label or in its product description, and it is directly associated with the power (measured in horsepower) of all of the pumps. Most backup sump pumps are going to remove a typical of 1,800 to 2,000 GPH with a 10-foot lift, which suggests they’re able to pour much water to a height of ten feet, and that is the standard level needed to eliminate water from below a cellar to the ground level.
Easy Installation Of The Sump Pump Battery Backup
Installing a battery backup sump pump is not a tough task. It takes simple plumbing methods; most communities need a licensed plumber to finish the setup. Consult your local building authority for the regulations in your area.
The simplest type of backup pump to put in is a combination unit, consisting of both the main pump and a backup pump nested together. Because the two pumps come attached, there is simply no requirement to splice the drainpipe to put in the second pump.
