Important facts about sump pump discharge lines
Did you know?
when the sump pump is running at full capacity, it can discharge up to approximately 20 gallons per minute. Having this amount of water near foundation walls can not only cause water penetration into your home, but can cause some serious structural damage to your home's foundation. Ensure discharge lines extend away from your foundation to a minimum of 8-10 ft away.
The sump pump should also have a battery backup system.
There are two types of battery backup sump pumps—DC (battery) and AC/DC. Battery backup systems will switch to DC battery power when the AC power is out or when the pump fails. But while the power is on, some pumps can run directly off the AC wall current without depleting the battery. Units that run exclusively DC power will only pump off battery power.
There are deep-cycle "maintenance-free" batteries, often sold as marine or solar batteries, as well as lead-acid batteries, otherwise known as "wet cell" batteries. You'll find wet-cell batteries most commonly used in vehicles.
These batteries do require you to add distilled water occasionally to keep the lead cells from drying out, preventing premature damage. Maintenance-free batteries are fully sealed, which you can set and forget.
