Sump & Drainage

2 guides

A sump pump is the last line of defense against a wet basement, and it only proves its worth during a storm, exactly when you cannot afford it to fail. This hub covers sump pumps and the drainage that keeps groundwater out of your lower level. You will find guides on how a basement sump pump works, choosing and sizing one for your home, and sump pump repair for the common failures: a pump that will not turn on, runs constantly, cycles too often, or hums without pumping. The guides explain the parts that usually cause trouble, a stuck float switch, a clogged intake, a failed check valve, or a tripped breaker, and which checks a homeowner can safely make versus when to call a pro. Because a pump tends to quit at the worst moment, we also cover the case for a battery backup so it keeps working through a power outage, when storms are most likely to knock out electricity. Cost here depends on pump type and horsepower, whether a backup or new pit is involved, and access to the discharge line, so we keep pricing to factors. Read the guide that fits your setup, then get connected with a licensed local plumber to install, test, or repair your sump system before the next storm.

Sump & Drainage questions

Why is my sump pump running constantly or short-cycling?

Constant running usually means water is coming in faster than the pump clears it, a float switch stuck in the on position, or a check valve that lets pumped water fall back into the pit. Short-cycling, turning on and off rapidly, often points to a pit that is too small or a float set with too little travel. Both wear the motor out early. Check that the float moves freely and the check valve holds; if the pump still cycles wrong, have a plumber assess the pit and switch.

How often should I test my sump pump?

Test it a few times a year, and again right before your wet season. Pour a bucket of water into the pit until the float rises. The pump should switch on, clear the water quickly, and shut off on its own. Also check that the discharge line runs clear and directs water well away from the foundation. If the pump is slow to start, noisy, or does not shut off cleanly, address it before the next heavy storm rather than during one.

Do I need a battery backup sump pump?

If your basement floods easily or storms in your area often cut the power, a backup is worth serious consideration. A primary sump pump runs on household electricity, so it goes down in the same outage a storm causes, exactly when groundwater is highest. A battery backup takes over automatically and keeps pumping for hours. It adds to the upfront cost but can prevent a flooded basement and the far larger cleanup bill that follows. A plumber can size a backup to your pit and inflow.
