Backup Sump Pump Power – Best Source
Join 1000's of Authors at StreetArticles Today!

Do you want to find a backup power source for your sump pump? Do you want to find the best backup power source based on your pumping needs? Are you one of the homeowners who think batteries are the only source of power available to run backup sump pumps?

Eighty percent of all homeowners think batteries are the only source of backup power for a sump pump. I have good news for you. There are at least four other power sources that can be used to use a backup pump. I will tell you what they are and then give information about why they are a good choice..

What power sources are available and what is the best source?

Batteries

The most common backup sump pump power source is batteries. We are talking about deep-cycle marine not car batteries, though some people do use a car battery in an emergency. The most common group sizes are 24, 27, and 31. The most common types of batteries are Flooded (wet), Gel and AGM. Gel and AGM batteries require no maintenance; however they are most expensive. On the other hand, flooded (wet) batteries require maintenance; they are cheaper and generally last longer. They vary in price from $100 to $300.

Batteries are a good power source if more than 1,200 gallons of sump water must be pumped per hour from the pit; however, most batteries can only provide enough power for a sump pump to run continuously for eight to twelve hours. A 6.5 amp battery backup sump pump running on a group 24 battery could run up to twelve hours continuously. Once the battery is depleted it takes up to six hours to recharge the battery if the battery charger amp strength is 20 amps.

If backup power is needed for several days with heavy rain requiring constant pumping, another backup power source will be required. Batteries can be used to run battery backup pumps that operate on DC (direct current) or primary electric pumps that operate on AC (alternating current) if DC is converted to AC. In this situation a battery backup sump pump could run for eight to twelve hours and then the converter unit could run the primary pump for another eight to twelve hours. This would provide enough time for the depleted battery to recharge. Inverters (also called a converter or auxiliary power unit) can provide enough energy to run an electric three-quarter horse power sump pump for more than eight hours.

Good choice! Even though batteries must be replaced every three to seven years, they are very easy to install and use. They support either a battery backup sump pump or an electrical sump pump if used with a converter. They support pumping capacity equivalency for one-third HP and as much as three-quarter HP with an inverter battery bank. Startup is automatic if the electricity fails.

Water

Water is becoming a more common backup power source used for sump pumps. Municipal water must be used instead of water from a private well because it has higher pressure and is available during a power failure. The higher the water pressure, the greater the amount of water sucked up from the pit and out the discharge pipe per minute. The minimum pressure required per manufacturer varies from 30 to 40 pounds per square inch (PSI). Pressure of one hundred PSI is too high. The amount of municipal water to force out 2 gallons of sump pit water varies by manufacturer. Some require two city gallons to pump out two pit gallons. Others use one municipal gallon to pump out two gallons of pit water. If a lot of water is removed from the sump pit regularly the water bill charge could increase.

Special pumps manufactured only for running on water power are required. The manufacturer calls them water powered sump pumps. The placement of these pumps varies by manufacturer. Some are made to sit in the sump pit. Others require installation on the joist beams above the pit. The best models can suck up 1,200 to 1,500 gallons of water from the pit per hour.

Good choice! Few moving parts! No batteries required! The pump begins operation automatically when electrical power fails. The only cost is the water used during operation. A water powered sump pump is required.

Propane, Gasoline, Diesel and Natural Gas

Propane, gasoline, diesel and natural gas are plentiful power sources. These sources are used to run generators. Generator power is measured in watts which is the energy source used to power electrical sump pumps. Manufacturers let consumers know how many amps each electrical sump pump requires to operate. Amps multiplied by volts (115 volts is most common) equals the amount of wattage a generator must provide to sustain running of a sump pump. A one-third horse power electric sump pump requires 2,200 watts at startup and 700 watts to keep it running. A one-half horse power electric pump requires 2,350 watts at start-up and 875 watts to keep it running. Manufacturers categorize generators by the number of watts supported.

Portable generators require manual start; this means you must be home to start them. They offer flexibility in that they are portable. Of the three types of gases (gasoline, propane and diesel) diesel is most safe.

Standby generators are powered by natural gas or propane tanks. They start automatically when electricity fails if they are installed with a transfer switch. Standby generators are pricey; however because of their wattage they can provide whole house power. If you live in an area where electricity fails frequently, no building restrictions exist regarding a four-foot by two foot device sitting beside the outside of your home and you wish to provide power to several household devices including sump pumps, a standby generator running on natural gas is most dependable and cost-effective in the long run.

Good choice! Standby generators with transfer switches are extremely convenient. They offer more than enough power to run any HP electric sump pump and provide the added benefit of supporting other household devices.

Solar

Solar energy is captured in solar panels and converted by a solar inverter from direct current to alternating current. One solar power panel is comprised of many solar cells. One solar cell generates one or two watts. Several solar cells combined create enough power to run an electric sump pump. A 10 amp electrical pump can run continuously for fifteen to twenty hours.

Good Choice! This saves the environment! No special pump to buy! They run an electric sump pump.

Conclusion You do have options for backup sump pump power. Understand your pumping needs. Then compare manufacturers and their specifications.
