While typical component lifespans are application specific, manufacturers suggest metal and plastic check valves should be replace every 5-7 years whereas check valves manufactured from rubber may remain fully serviceable for up to 35-50 years.
How do I know if I have a bad check valve?
Symptoms of a Failing Check Valve
For example, failing check valves will start to vibrate and even lose some internal parts when problems begin to arise. Other symptoms of check valve failure include reverse flow and excessive component wear and damage. Check valves will also emit noises as they start to break down.
Do check valves need maintenance?
Maintaining a Check Valve
A check valve doesn’t require too much maintenance. They are built to last for years. However, they can develop leaks if debris or other foreign particles get stuck between the ball and the seat, causing check valve function to degrade.
What makes a check valve go bad?
Improper installation, maintenance, and assembly As with any mechanical equipment, improper installation, maintenance, and assembly of check valves can lead to costly, time-consuming damage and, ultimately, failure.
How often should a sump pump check valve be replaced?
It’s a difficult question to answer because every system will have some differences. Typically, our valves will last in an excess of 5 to 7 years, so we recommend replacing it that often. However, if the pump cycles frequently, that can result in the check valve wearing out faster than that.
How long do check valves last?
While typical component lifespans are application specific, manufacturers suggest metal and plastic check valves should be replace every 5-7 years whereas check valves manufactured from rubber may remain fully serviceable for up to 35-50 years.

Can a bad check valve cause low water pressure?
If one of these valves is partially or fully turned off for some reason, it can cause your water pressure to decrease greatly.If you think a closed or partially closed valve may be the cause for your low water pressure, check both main valves to make sure they are fully open.
Do check valves fail open or closed?
One, check valves are prone to jamming in the open position, thereby becoming an uncheck valve of sorts. Two, they are prone to jamming in the closed position, preventing water flow in any direction.If the check valve is stuck open, the pump runs and pumps just fine; however, it won’t prevent backflow or flooding.
Should I replace check valve when I replace sump pump?
Check Valve Basics
When a sump pump check valve is not working, water flows back from the discharge piping into the sump pump pit.So, a check valve can cut down on electrical costs and prolong the life of your motor. If your sump pump is often running, it could be a sign that your check valve needs replacing.
How do you know if the check valve is bad on a sump pump?
How to Tell if the Check Valve is Bad
- Check for leaky or moisture on seals, connections and valve.
- Fill the put 1/4 to 1/2 with water and see if it drains.
- Watch for water backwash into your basin during testing and rainstorms.
What happens when sump pump check valve fails?
A broken or missing check valve can result in one-third to two-thirds of the water to flow right back into the pit! And that will overwork the pump. Continually flooding sump pit. – In rare cases, there is a continuous flow of water into the sump pit due to a high water table or an underground spring.
Do foot valves go bad?
Yes, foot valves can fail, and the symptoms will be loss of prime.
What’s the difference between a foot valve and a check valve?
Check valves and foot valves are designed to stop water from going backwards when the pump shuts off. Check valves are normally on the discharge side of pumps, and foot valves are on the intake of pumps.
What happens when brake booster check valve goes bad?
When the check valve is not working correctly, the operation of the brakes becomes much more difficult. Specifically, the pedal goes from smooth and soft to aggressive and very difficult to press down. This is due to the excess pressure inside the master cylinder, which the check valve is designed to regulate.
How do you fix a leaky check valve?
First shut off the water to the leaking water valve. Next remove the handle from the stem and then loosen and remove the packing nut. Remove the old washer and slide on the new one. Reinstall the packing nut, tighten lightly with a wrench (don’t over tighten at this or any other point) and reattach the handle.
How often should water valves be exercised?
Valves affecting hospitals, schools, and valves on water mains of diameter 16-inches or greater should be given priority, and should be exercised/assessed once per year.
How far should check valve be from well pump?
If the pump does not have a built-in check valve, a line check valve should be installed in the discharge pipe within 25 feet of the pump and below the drawdown level of the water in the well. For deeper settings, a line check valve is recommended every 200 feet.
