Sump Pump Repair, Replacement and Backup
Sump pump repair and replacement, with backup options and alarms discussed for finished lower levels.
Overview
Sump Pumps, Explained.
A sump pump spends most of its life waiting. Then, during a heavy spring rain or a rapid thaw, it may run repeatedly for hours, and the finished lower level below grade depends on it working each time. Because it is so rarely noticed between those moments, a worn switch or seized impeller is often discovered only when the water is already rising.
Whether the lower level holds a family room, a laundry, a spare bedroom or simply the furnace and the holiday boxes, the sump system deserves the same consideration as any other protective system. A visit looks at the pump, the basin, the check valve, the discharge line and the power supply as one arrangement, and at what happens if any single part of it fails.
The visit
Sump Pumps: What the Visit Involves
- 01
Test under real conditions
The basin is filled to trigger the pump, so we can watch the switch engage, the water level drop and the pump shut off cleanly. Run time, noise and vibration all tell us something.
- 02
Inspect the whole system
The check valve, discharge pipe, basin, lid and electrical supply are examined. A healthy pump connected to a failed check valve or a frozen discharge line will still let a lower level flood.
- 03
Discuss backup protection
We talk through what happens during a power outage or pump failure, and which backup arrangements, battery or otherwise, suit the home, its plumbing and how the lower level is used.
- 04
Replace or repair
Switches and check valves can often be replaced alone. Where the pump itself is worn, it is replaced with one sized to the basin and inflow, and the system is tested again before we leave.
How often should a sump pump be tested?
A simple test, slowly pouring a bucket of water into the basin until the pump starts and empties it, is worth doing a few times a year and particularly ahead of the wetter spring months. Watch that the float rises freely, the pump starts promptly and shuts off cleanly. If the pump hums without moving water, or fails to start, that is the time to have it looked at.
Do we really need a battery backup pump?
Heavy storms and power outages often arrive together, which is precisely when a primary pump is most needed and least able to run. A battery backup provides a second line of defense against both power loss and primary pump failure. Whether it is worth it depends on how often your pump runs, how the lower level is finished and what is stored there. For a finished lower level, many homeowners decide it is.
What does the check valve on the discharge pipe do?
The check valve stops the water already in the discharge pipe from falling back into the basin when the pump shuts off. Without it, the pump re-pumps the same water repeatedly, cycling more often and wearing faster. A failing check valve can also be the source of a loud thud when the pump stops. It is an inexpensive part relative to the pump, and worth checking during any service.
Why does our sump pump run even when it has not rained?
In many homes, groundwater keeps reaching the drain tile around the foundation well after the rain stops, especially during a spring thaw or in a high water table. That can be normal. Running every minute or two in dry weather, however, may point to a failed check valve, a discharge line that drains back into the basin, a stuck switch, or water from another source, such as a leaking irrigation line.
