Sump pump
June 9, 2021

The sump pump is the heart and lungs of a home’s waterproofing system. When properly installed and maintained, its the most important tool you have to keep your basement dry. However, if your sump pump stops working for any reason, your home’s waterproofing system will probably fail and your basement may get wet.

Have you ever noticed that sump pump failures usually occur at the most inconvenient time? During a rainstorm, when the sump pump is supposed to be doing its most important work, that’s when we usually find out which sump pumps work and which ones fail. There are a few things you should regularly check to make sure your sump pump is ready to do its job this season.

5 Steps for DIY Sump Pump Inspections

Before you start, make sure to unplug any electrical power leading to your sump pump.

1. Check for Debris in Sump Basin

Make sure the sump pump pit is free from debris. You might be surprised at the kinds of things that can end up here as part of typical home life- children’s toys, items stored nearby that fall in, etc.

Anything that falls into the basin can get into the sump pump unit and interfere with moving parts, particularly the float mechanism. The float mechanism has a key role in sump pump operation, so be sure there is nothing interfering with it.

2. Test the Float

Fill the sump pump pit with water and make sure the float starts and stops the sump pump as designed.

3. Inspect the Check Valve

The check valves ensure that no water will go back into the sump pump pit when the sump pump shuts off. However, sometimes these are improperly installed. An arrow on the check valve points in the direction the water is supposed to flow, which should not be towards the sump pump.

4. Clean the Weep Hole

Some sump pumps have a weep hole between the sump pump and the check valve. You can clean this with a toothpick or other tiny object. Be careful not to break anything into the weep hole.

5. Clean the Impeller

The impeller is a small filter that can become clogged. If your sump pump has stopped running suddenly or is making a whining noise, this could be the problem.

The impeller should be connected to the sump pump with bolts and may need a thorough cleaning to work properly.

Two More Common Sump Pump Problems

1. Odor in the Sump Pump

The sump pump trap always retains some water. But when the water doesn’t flow into the basin during the dry seasons, an odor often forms. You can help eliminate the odor by cleaning the basin with a 5-part water/1-part bleach mixture. You could also fill the basin with water until the sump pump engages, which will cycle the water and help eliminate odor.

2. Back-Up Power Source

Having a backup power supply or generator is a great way to avoid overflow if there is a power outage. Most power outages happen during heavy thunderstorms that bring a lot of rain in a short period of time, which is exactly when you need your sump pump most. If you lose power, the backup system will take over to get rid of the water as the basin fills up.

There are also water-powered backup systems that tap into your home’s water supply to provide the energy needed to run the sump pump.

A backup power source is a great investment to make in order to avoid the costs of a flooded basement.

How To Install A Sump Pump In Your Home?

If you are having problems with water even after you’ve had waterproofing services in your basement or crawl space, it may be time to consider the idea of sump pump installations. Whether you are dealing with an improperly draining yard or you are below sea level and are experiencing constant issues with water, sump pump installations could be the answer. Find out a little bit about sump pump installations and how they can help with your waterproofing problems.

Stop the Worry

If you’re worrying every single time it rains or storms, you need to take action. Sump pump installations are a great way to make sure that you’re not worried about the basement or crawl space flooding every single time you feel a sprinkle. They give you peace of mind that you can enjoy time away from home, a vacation, or a shopping trip without having to rush back to the house and take care of a flooded basement.

Battery backup sump pumps give you more peace of mind because they will be on even if the power goes out. This can be of great importance when you are in the middle of a storm. You can worry about your own safety and the safety of your family instead of whether or not your basement or crawl space will remain dry throughout the storm and potential power outage.

Sump Pump Installations are an Investment in Your Home

When you invest in sump pump installations, you are really making an investment in your home. You no longer need to worry about your home’s worth after so much water damage. You can simply sit back and relax as you know your sump pump will take care of the rest. There will be upfront costs, but the savings to your finances due to never-ending flooding cleanup and extensive waterproofing will be made up continuously.

Satisfied Customer Reviews

Jeff Wolfe was excellent providing a thorough inspection, informing us about the company history, the technology and strategies utilized and our options. I would highly recommend Jeff and KC waterproofing!
First class in every way. Very friendly and accommodating. They do things the right way even if it takes much more time to get the project done. Their job of putting things back the way it was, was spectacular! They even replanted the flowers they had to dig up.
Great company and extremely easy to work with. Riley was my point of contact and he explained everything very well. After I denied working with them on one property (due to family issues) Riley happily messaged me back when I needed help with another property. The solution was a hard one to figure out, but Riley constantly made suggestions that would hopefully solve the issue without doing too much work that isn’t needed. Riley clearly explained what I needed and don’t and also gave guidance for other issues I had going on regarding window sealing.

Schylur Oakes and his crew were the ones that came and worked on my property. Schylur was extremely personable and friendly. He constantly ran back and forth from the back of the house (where the work was being done) to the front of the house to ring my doorbell and ask me if I was okay with what they were doing, if I wanted them to change anything etc. One moment he even came and asked if I really need the work to be done since there were sprinklers near my basement window and maybe that was the issue instead, not foundation and rain water. I clarified that I don’t even use my sprinklers and I still have water entering but I was glad he even brought it up and checked with me before proceeding. Schylur ended the day by having his crew clean up after themselves and showed me around and told me everything they did.

Only issue I had was payment processing was a pain. It’s 2026, I shouldn’t have to give my card number over the phone for a deposit, just send me a link to a secure site to enter it. How can I trust some random number and voice over the phone? Then for the final payment, having to manually type out and input my card information in to a tablet while it was raining was a slight nuisance. I have my own small business and use Square tap to pay. It’s not that expensive. Come on guys, if I’m using it for my little business, you can afford it for your long standing company. Just my 2 cents.
Camden came and did a thorough inspection of our foundation and explained the findings well. I felt he was honest with his recommendations and did not try to convince us to do something that wasn't necessary.
Will use KC Waterproofing and Foundation Repair again and highly recommend.
Thank you Cam!
Very professional, informative and did a great job cleaning up after the job.
Jeff was very professional and informative. Fortunately we didn't have foundation problems but if we do we know who to call.
Mario was here on time & was very informative about questions I had. A 10 out of 10. Thank you …Mario
This is the second time I've used this company. Great company. They have good employees. Fran did a great job of explaining everything, even the financing. I thought the lending company had great options. When it was time for my French drains to be installed. They came on time and ready. They even did a crawl space protective cover. Great team, they worked well together. Took the whole day but got it all done. Cleaned up well afterwards. The price was reasonable. Jackson explained everything as it went along. Kind, friendly service.
Mario serviced my sump pump today and did a good job. He also replaced tape on my wall shield. He provided excellent customer service and was willing ti come out any time needed or said to call him anytime if I had any questions.
KC Waterproofing and Foundation Repair has taken incredible care of my home through multiple visits. Gary and Davan handled my initial sump pump installation and crack repairs, and they were not only skilled but genuinely thoughtful throughout the process. We had a bit of early miscommunication, and instead of brushing it aside, they listened, acknowledged what happened, and adjusted the plan so everything aligned with what I needed.

They brought me in at every step—walking me through pump location options, explaining the exit pipe decisions, and making sure I felt confident about the work being done. Their friendliness and respect made a stressful repair feel manageable.

Later on, I had some cracks that needed to be reassessed, and Mario came out to take a look. He was incredibly kind, patient, and thorough, and he did an amazing job with the additional repairs. His calm, reassuring approach made me feel completely taken care of.

I also want to highlight Don, the manager, who is just as kind and committed to making sure customers feel heard and supported. It’s clear this team truly values doing right by people.

I’m grateful for their care and would absolutely recommend them for any foundation repair or waterproofing needs.
