Last Updated on by Anthony Brown

There are many different reasons why a sump pump check valve failure can occur. When the failure occurs, your pump may seem to run constantly because there is no valve to signal it to turn off. Check valve failure can result in your pump wearing out very quickly due to constant use. 

Here are some of the reasons why sump pump check valve failure can occur, what can be done to remedy the problem and how to tell if it is happening to your check valve.

Sometimes check valves can be completely missing, especially in older homes. If you just purchased your home, it is good to check and make sure your sump pump is only coming on when needed.

A missing valve means that water that is pumped out can flow back into your sump pit instead of out the discharge pipe which makes the pump run much more often than it should. A simple yet inexpensive repair can mean you don’t have to replace your sump pump much sooner than needed and in some cases the sump pump check valve might be stuck!

How to Tell if the Check Valve is Bad

You can tell if a check valve is working properly look for water flowing back into your pit after the pump turns off.

Most people only buy 1 or 2 sump pumps in their life so they have no idea how to tell if their check valve is bad – luckily it is easy if you know what you are looking for!

Step by Step Instructions:

  1. Check for leaky or moisture on seals, connections and valve
  2. Fill the put 1/4 to 1/2 with water and see if it drains
  3. Watch for water backwash into your basin during testing and rainstorms

My Sump Pump Has Shifted Position

A sump pump that has moved can mean that the check valve is not aligned correctly meaning your pump may never know that it should shut off.

There are many reasons a pump can move. Seismic activity or unstable ground beneath a home is one culprit. An amateur trying to repair or install a sump pump can also spell trouble.

I have Defective Valves or Sump Pump

Like anything you use very often, it is important to have a quality product. Cheaper sump pump systems are made of inferior materials that can wear out or fail more rapidly than their more expensive and higher quality counterparts.

If you have to replace your pump, then it is going to be to your benefit to purchase a better pump than the one you are replacing, we recommend choosing from this list of best check valves.

Debris Blocking Discharge

Sometimes the water flow in your basement check valve will get blocked by debris that makes it past your filter and pump. Most check valve systems can clean debris to prevent backups but if the blockage is too bad it may have to be cleaned by hand. After removing the blockage make sure water is flowing out the discharge pipe.

Getting the Correct Check Valve Replacement

Making sure that replacement occurs correctly is important to your sump pump system. If you suspect your valve is the problem, it is still a good idea to call a service professional.

Sometimes one problem may be systematic of much larger issues with your system. A professional can make sure that the whole system is checked which saves time and money in the long term.

Valves vary in size based on the manufacturer of your pump. It is normally very easy to source or get a valve. A service professional often has valves in stock, so you don’t have to worry about finding the right one for your pump.

Banging Sounds from Sump Pump Flushes

banging sound when your pump comes on and begins pumping is referred to as water hammering.

This can be solved by adding a spring-loaded check valve sometimes called a silent valve. This is a straightforward and inexpensive fix to what is sometimes a very loud problem.

Importance Of Good Check Valve Maintenance

Keeping your basement dry is very important. Don’t let a cheap sump pump mean that you go without good drainage for a long time due to the cost of replacement.

Getting your pump checked now can save a lot of money over the years and result in a drier home without major moisture issues causing damage. Seasonal maintenance and cleaning can go along way in extending the life of your sump pump!
