    Here are some reasons why sump pump check valve failure can occur. Learn how to remedy the problem and 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 pumped out can flow back into your sump pit instead of out the discharge pipe, making 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 sooner, 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 correctly. 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 terrible – 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 moved can mean that the check valve is not aligned correctly, meaning your pump may never know 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 essential 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, it will be beneficial to purchase a better pump than the one you are returning; 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 passes 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, ensure water flows out of 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 or a more significant issue with your system. A professional can check the whole system, saving time and money in the long term.

    Valves vary in size based on the manufacturer of your pump. It usually is straightforward 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 a long way in extending the life of your sump pump!
