Selecting the Right Sump Pump
The correct selection of your sump pump may depend on the type of foundation you have, the slope of the land, and the extent of your water problem. To find the right sump pump system for your residential or commercial location, consider these factors:
Backup Sump Pump and battery backup. Some sump pump systems (such as the StormPro Battery Backup Sump Pump System (2100 GPH @ 10') with Battery) can activate automatically in the event of a failure of the primary sump pump. A secondary pump such as the StormPro model just described will often come includes with a typical lead-acid battery and a trickle-charge battery charger.
- Automatic vs. Manual Operation: The operation mode of your sump pump may be a very important factor, especially if the location of your site is at a location that is not inhabited or infrequently checked. You may not want worry about a flood in your home that occurs while you are at work or on vacation. A sump pump with a manual operation requires an operator to turn the machine on and off. Automatic switches include float switches, low level pressure switches, and pressure switches. An automatic operation pump has a switch that is wired to the pump to turn it on and off when the water in the sump pump reaches certain levels.
- Horsepower: Horsepower refers to the power of the sump pump engine. Sump pump horsepower may range from ¼ to 1+ horsepower.
- Head Pressure: Sump pump is the maxim mum vertical height that the pump can move groundwater before the pump loses flow. a pump's head pressure is described in terms such as shutoff head or max head. For example, a machine with a 20 foot max head (shutoff head) will pump water as high as 20 feet before it loses flow. Head pressure can be described using the following equation P=ypg (P=fluid density, Y is fluid column height, g=the force of gravity (at 9.8 m/sec2)). Other factors may affect head pressure, such as column diameter increased friction from long columns, and loss from bends/elbows.
- Cord length: Sump pumps do not run on hopes and dreams (if only). Sump pumps either required power from the nearest power outlet in your home, or a charged battery. The cord length is the length of the power cord from pump to the nearest electrical outlet. Cord length may be a consideration when deciding on a sump model, if the site of the excavated sump pump is a considerable distance from the closest electrical outlet.
- Phase & Voltage: The available voltage options consist of 115 volt, 230 volt, and 460 volt. Sumps may be offered in one of the following settings: single phase and three phase.
- Alarm and Backup System: I'm sure that you already have selected or will selected a fine sump model that will offer you thousands of hours of quality production, but no pump will last forever. You may want to invest in a system equipped with a backup sump pump that begins firing in the event of a primary failure, or an alarm system to alert you when one of the pumps has failed.
