Home are a pump unit with an outlet hose that drains basement flood waters out of a home into a drainage field away from the property. Standard home pumps are installed into the lowest area of the flooring in the basement level of a home. When flood waters are triggered, this causes a float ball sensor in the unit to extract the water from the basement via the pump. Because of the pump's location, the water will continue to naturally make its way into its unit.
Although these pumps are great, they tend to wear down at some point, or lose the ability to operate because of a loss of electricity to the home. These Backup pumps are an important part of a home installation; because they are expected to work in the event when the main sump pump fails.
backup sump pump units consist of a two-part system; the first component of the system is usually a basic standard sump pump unit that is connected to a smaller pump unit. The advantage to using this pump is that they are powered by deep-cycle marine batteries which are capable of being used in conditions where there is heavier moisture. However, marine batteries should still be placed on shelves, off of the floor. This allows them to kick in and maintain operation in the event that the standard pump breaks down.
Lastly, people installing these units should also take the time to ensure that they're installing the unit correctly. Failure to do so can cause and lead to a larger flood occurring, because of the inability for either pump unit to operate.
It's important that a check valve is installed into the line; when the check valve is being installed, the individual should seal the check valve properly by using plumbing tape to secure the fitting from water entering the line.
Some final things when installing a backup pump is to choose a diameter of piping that is at least an inch and a half in diameter for the outlet piping; this helps to ensure a proper rate of flow, as well as water pressure within the line. The backup sump pump, while a backup, still needs to be charged.
The individual should take care to install both the near electrical outlets high up on the walls. An overlooked thing when installing a replacement with backup pump is the drain hose; it's important that the drain hose is positioned far away from the home's basement to prevent the flood waters from re-entering the house.
