Uncover the secrets: how to check check valve on sump pump for optimal drainage

A check valve is a crucial component of your sump pump system, preventing water from flowing back into the sump basin once it has been pumped out. A faulty check valve can compromise the effectiveness of your sump pump and lead to flooding in your basement. This comprehensive guide will provide you with step-by-step instructions on how to check the check valve on your sump pump.

Materials You’ll Need

• Screwdriver
• Flashlight
• Bucket or container

Steps to Check the Check Valve

1. Safety First

Turn off the power to your sump pump at the circuit breaker panel or fuse box. This will prevent the pump from accidentally turning on while you are working on it.

2. Locate the Check Valve

The check valve is typically located on the discharge pipe of the sump pump. It is usually a small, cylindrical device with a spring-loaded flap or ball inside.

3. Inspect the Check Valve

Use a flashlight to inspect the check valve. Look for any signs of damage, such as cracks, leaks, or corrosion. If you notice any damage, replace the check valve immediately.

4. Test the Check Valve

To test the check valve, pour a bucket or container of water into the sump basin. The water should flow out of the discharge pipe. If the water does not flow out, or if it flows out slowly, the check valve may be clogged or faulty.

5. Clean the Check Valve

If the check valve is clogged, you can try to clean it. Use a screwdriver to remove the check valve from the discharge pipe. Be careful not to lose the spring or flap inside the check valve. Clean the check valve with soap and water, and then reassemble it.

6. Reinstall the Check Valve

Reinstall the check valve on the discharge pipe. Make sure that the spring or flap is facing in the correct direction. The spring or flap should be facing away from the sump basin.

7. Turn the Power Back On

Turn the power back on to your sump pump at the circuit breaker panel or fuse box. Test the sump pump to make sure that it is working properly.

Troubleshooting Common Check Valve Problems

1. Check Valve is Clogged

If the check valve is clogged, it will not allow water to flow out of the discharge pipe. This can cause the sump basin to overflow and flood the basement. To fix this problem, clean the check valve with soap and water.

2. Check Valve is Faulty

If the check valve is faulty, it will not prevent water from flowing back into the sump basin. This can also cause the sump basin to overflow and flood the basement. To fix this problem, replace the check valve.

Signs of a Faulty Check Valve

• Water flowing back into the sump basin
• Slow or no water flow out of the discharge pipe
• Sump basin overflowing
• Basement flooding
