Sump pumps help manage groundwater before it reaches your basement floor. In Madison and Greater Wisconsin, spring thaw, periods of heavy rain, and saturated soil can increase pressure around the foundation and push water toward lower levels of the home. When the sump system cannot keep up, water intrusion can develop quickly.

Southport Plumbing, Heating, and Cooling provides sump pump services, including installation, repair, maintenance, and backup protection. Our team evaluates how the system is handling water around your home and recommends the right service to keep drainage working properly.

Sump Pump after repair needed due to lack of maintenance.

Sump Pump Services

  • Installation of new sump pump systems – Set up systems based on basement depth, drainage layout, and groundwater conditions
  • Replacement of failing or undersized units – Upgrade pumps that no longer keep up during heavy water load
  • Repair of components and connections – Restore proper activation, discharge flow, and system response
  • Battery backup system installation – Add secondary protection during storms and power loss
  • Routine maintenance and testing – Check operation before peak demand periods and seasonal weather shifts

How Sump Pump Systems Work in Your Home

A sump pump system includes more than the pump itself. Water collects in a sump pit at the lowest point of the basement or crawl space, and the pump then moves it through a discharge line away from the home. A check valve helps prevent water from flowing back into the pit, and proper drainage outside the home helps keep water away from the foundation.

When one part of that system fails, the entire drainage process can be affected.

When to Call for Sump Pump Service

  • Pump runs continuously or cycles too often
  • The system does not turn on when water is present
  • Water collects around the sump pit or near the foundation wall
  • Unusual noise, vibration, or inconsistent pumping
  • The pump has not been inspected in several years
  • Basement moisture appears during wet weather

Common Sump Pump Problems

Several common issues can reduce sump pump performance or cause full system failure:

  • A stuck or failed float switch that prevents proper activation
  • A clogged or frozen discharge line that blocks water movement
  • Check valve failure that allows water to flow back into the pit
  • An undersized pump that cannot keep up with site conditions
  • Power loss without backup protection during storms or outages

Identifying the failure point early helps reduce the risk of basement water buildup.

What Happens During Sump Pump Service

We evaluate both the pump and the flow of water through your drainage system.

  • Inspect sump pit, pump condition, and discharge line
  • Test the float switch and activation response
  • Check valve operation and water flow direction
  • Evaluate pump size relative to demand based on observed water conditions
  • Identify repair needs or recommend replacement or backup options
  • Confirm that drainage is directing water away from the home properly

This process helps determine if the system is operating correctly under current conditions.

Backup Systems and Power Protection

Storm conditions that bring excess groundwater can also interrupt power. When that happens, a primary sump pump may stop operating at the exact time it is needed most. A battery backup system provides secondary protection, allowing water to continue to drain from the sump pit during an outage.

Backup protection is especially useful for homes that experience repeated wet-weather demand or rely on a single primary pump.

Preventing Sump Pump Failure

Routine service helps reduce the risk of unexpected failure when your system is under the most pressure.

  • Schedule annual inspection and testing
  • Clear discharge lines and verify the outside drainage path
  • Check pump performance ahead of spring thaw and heavy rain periods
  • Add backup power if the system depends on one electrical source
  • Confirm the current pump still matches the drainage demand

Phil was outstanding! He diagnosed a problem that several other techs from a different company couldn’t figure out. He was so friendly and took the time to explain everything clearly. Highly recommend Phil from Southport!

Great experience on updating our HVAC systems to heat pumps/backup furnaces.
Ryan, Oliver, Andrew and Jacob (all installers for Southport) are wonderful, competent, and delightful young folks, who gave great service doing the physical upgrade of 2 older heat/ac systems.

I highly recommend Southport for your future HVAC upgrades. All the folks from the person doing the bids (Adam) to Manager (Jackson) to all the installers, are first class, professional and proud of where they work and what they do.

Losing AC in hot weather is never fun, but Southport made the whole process as painless as possible. They were quick to respond, easy to work with, and got everything moving fast when we really needed it.

From the initial quote to the installation of our new AC and furnace, everyone was friendly, knowledgeable, and professional. The communication was great, the work was done efficiently, and everything went smoothly.

We're extremely happy with the result and wouldn't hesitate to recommend them to anyone looking for HVAC work.

Got a furnace replacement and a/c unit install. Both work great. The hvac techs worked very hard but they were not so thrilled to be doing a full install on a friday. they made it clear by complaining within earshot for the whole 7 hours. So maybe consider not scheduling with them on a Friday and it may be a better experience for you. 5 stars

I purchased my furnace from Southport and needed service when my AC went out during a storm. Andrew,my service tech was fantastic! He explained everything, got the parts the same day, and had me up and running in no time at all! At his recommendation, I also purchased a surge protector and maintenance agreement so I can rest easier during storms. Thank you Andrew!!

I was referred to Southport by a co-worker. Their staff is super friendly and informed. The sales manager Nate was reasonable to work with. You can probably save a few hundred bucks going with a smaller company with less overhead, but I think the peace of mind that comes along while working with an established company like Southport, is much more important. They got me booked for an instilation appointment within two days of signing a contract! Their technicians were polite and did the best they could at keeping my carpeted basement clear of mud, considering the first few hours they were there was during a rainstorm. Whatever mess they made they cleaned up. The installation took longer then expected (about 10 hours) but there was a lot of work to be done, and the technician thanked me for my patience. He said it's nice to be able to take their time and make sure everything is installed perfectly! All and all, I had a positive experience, and highly recommend using Southport. Friendly and fast service at fair price!
