Sump Pump Basics

Types of Sump Pumps

There are generally two types of sump pumps: submersible pumps and pedestal pumps. Submersible pumps are installed in the sump pit and are designed to be fully submerged in water, whereas pedestal pumps are installed outside the pit and have a long, vertical discharge pipe. Both types have their pros and cons, and the best choice depends on your specific needs and budget.

How Sump Pumps Work

A sump pump is a small pump installed in the lowest part of a basement or crawlspace to help keep the area under your home dry and prevent flooding. When water enters the sump pit, the float switch elevates, and the sump pump begins to pump the water out. The water is then discharged through a pipe away from your home. This helps prevent ground water and water from a high water table from seeping into your basement or crawlspace and causing damage.

Importance of Sump Pump Maintenance

Your sump pump is a crucial line of defense against basement flooding and water damage. To ensure its proper functioning, it is essential to perform regular maintenance. Here are some key maintenance steps:

Test your sump pump by pouring a few gallons of water into the sump pit. Make sure the float switch elevates, the pump starts, and the water is pumped out.
Inspect the discharge pipe for any clogs, leaks, or obstructions that could prevent the water from being pumped out.
Clean the sump pit to remove any debris that might interfere with the pump’s operation.
Check the power supply to ensure the pump is receiving power, and consider installing a backup pump in case of power outages.

By taking these steps, you can help ensure your sump pump is working efficiently and effectively when you need it most.

Examine the float switch to make sure it’s free to move and not obstructed. Clean any debris that could hinder the float’s movement, and then test the float switch by manually lifting it. The pump should activate when the float is raised.

Inlet Opening and Screen Check

Inspect the inlet opening and screen for blockages that might restrict water flow into the pump. Remove any obstructions and debris that could compromise the pump’s efficiency. Regularly clean the inlet screen to ensure the optimal functioning of your sump pump.

Safety Measures

Always keep safety in mind when inspecting and maintaining your sump pump. Before conducting any tests or inspections, make sure to unplug the pump and turn off the circuit breaker to avoid electrical hazards. If your sump pump is connected to a GFCI (ground-fault circuit interrupter) outlet, ensure it’s working properly by testing the GFCI and resetting it if necessary.

Remember to routinely check your sump pump’s components, such as the float switch, inlet screen, and check valve, for efficient performance. By performing regular maintenance and inspections, you can ensure the longevity and proper functioning of your sump pump.

Cleaning and Repair

Sump Pit Cleaning

To maintain the proper functioning of your sump pump, regularly clean your sump pit. Start by removing the pump from the pit and draining any standing water using a shop vac. Next, use a damp cloth or a sponge to wipe down the walls of the sump pit. This will help keep debris and buildup at bay, ensuring that your system continues to operate smoothly.

Debris Removal

Over time, your sump pump can become clogged with debris. To prevent this, regularly check the pump’s intake screen, which can be found at the base of the unit. If you notice buildup on the screen, gently remove it with a plastic scraper or putty knife, being careful not to damage the pump. Once the debris is removed, rinse the screen thoroughly with a garden hose.

Discharge Line Maintenance

It’s important to keep the discharge line clear and free-flowing to prevent backups and flooding. Periodically inspect the discharge pipe for any signs of clogging or obstruction. If you have a check valve, disassemble it carefully, drain any trapped water, and clean the valve thoroughly. Afterward, reassemble the valve and test your sump pump to ensure that the discharge line is functioning correctly.

Impeller Inspection

The impeller is a vital component of your sump pump, propelling water up through the discharge pipe. Regularly inspect the impeller for wear and tear, such as cracks, breaks, or warping. If the impeller is showing signs of aging or damage, it’s time to replace it. In some cases, you may need to replace the entire pump if the impeller cannot be replaced separately.

Pump Replacement

Over time, your sump pump will age and wear down, potentially leading to reduced performance or failures. To avoid costly repairs and potential water damage, proactively replace your sump pump based on its expected lifespan or when you notice signs of aging.
