4 Causes of Sump Pump Check Valves Failure

If you are a property owner dealing with troublesome water system situations, you may have a problem with sump pump check valves that don’t do their job correctly. Understanding the use of a sump pump appliance and the role of the check valve will help you to troubleshoot accordingly. In addition, check valves are often part of other water-using appliances, and knowing more about how these items will help you to maintain and repair systems correctly.

The sump pump is a pump installed in a basement or other area of a property that routes excessive water away from the property to help avoid water damage. The sump pump has a piece called a check valve that is designed to stop water from “backflowing” or falling back out of the pump when the pump stops. The check valve can experience problems over time, which may lead to noisy operations and possible water damage.

1. Leaking

In some cases, sump pump check valves can leak. This is always a potential problem, since anything around the check valve may get exposed to continual moisture, which can lead to mold, mildew or other unpleasant situations. Look at the connecting infrastructure of a sump pump check valve to make sure it is solidly sealed and not prone to leaking over time.

2. Vibrations and Knocking

Some property owners complain of noisy sump pumps, where the problem can occasionally be traced back to an issue with the check valve. Some valve types have rubber flanges on the sides that vibrate according to the operation of the pump. When these are vibrating out of control, it can cause problems. Also, a pump can get stuck in an improper position, leading to other problems over time. One way to avoid this kind of issue is by testing your sump pump regularly to make sure it is in the right position and dealing with excess water as intended.

3. Spring Valve Problems

Some kinds of sump pump check valves are composed of a ball and spring design. If the spring gets excessively worn over time, the check valve may not work right. A bad check valve will generally need to be replaced. Professional plumbers can consult on what needs to be done to make a sump pump or other appliance work correctly.

4. Blocked Open Valves

Some other check valve types have a small door design that swings open when the pump is running and closes when the pump stops working. In some cases, these valves can get blocked open by debris, where the valve is unable to close properly. This will lead to backflow and requires repair or replacement of parts.

All of the above are problems that property owners might run into with a sump pump check valve. it’s a good idea to visually inspect and operationally check all of the parts of a sump pump regularly. Other tips for property maintenance help your sump pump to work less and promote better longevity for all of its parts. Cleaning downspouts and gutter’s can help, as can installing French drains on the outside of a property to help deal with storm water or “waste water.” Look at your property’s current water runoff set up and see if they need any additional maintenance or improvement to protect your investment in real estate.
