Are check valves ever immediately above the sump pump or even threaded to it? I am familiar with check valves a bit higher up and out of the sump and then a weep hole is drilled in pipe in sump to prevent air lock in that section.
Generally the check valve will be 8″ up from the pumps discharge to approximately 12″ above floor level. Any check valves with a MPT (Male Pipe Thread) connection that are designed to thread directly to the sump pump discharge housing must have the air release hole / weep hole drilled into the check valve body directly above the MPT connection and below the flapper. Some of these threaded check valves will come with a pre made weep hole.
Any videos this clear and concise on how spring loaded check valves work? I've got one in a condensate pump (Liberty LCU-20s) that won't close. It would be nice to be able to see inside in order to understand what's going on better.
Thank you for watching. There are a lot of variables so it is hard to say what is the problem, but yes it's good to check all washers to make sure it has a good seal.
It depends on how it fails. If the check valve is stuck closed then it might sputter. If the check valve does not close properly then water will rush back into the pump and it will run more frequently.
What if i put check valve in oulet dan inlet pipe? Is my boster become safer? Is reduce waterhammer much? There is still litle waterhammer when i use one check vale in inlet pipe .
Thanks for watching. Water hammer is the shockwave created when a pump or valve suddenly closes. It is like slamming on the brakes when driving at highway speeds. To fix water hammer, tighting the mounting clips on any pipes can reduce the noise. Installing a dedicated water hammer arrestor will create a cushion for the water, reducing the shockwave. A check valve will not act as a cushion as this is another hard stop in the system.
There are different types of check valves. For a sump pump it will have a hinge and a disc that closes when water is pulled back down by gravity. The duckbill valve is a flexible one-piece sleeve in the shape of a duckbill which will open when the water is flowing in one direction, and enough back pressure will force it to collapse inward and close, preventing back flow.
Yes, a check valve is a type of backflow preventer but has a different appliacation. A backflow preventer is necessary to prevent contaminated water from flowing into potable water sources. A check valve is generally not as robust and cannot prevent that sort of contamination. In the case of a sump pump, this is not a problem as both water sources are the same.
Thanks for watching. Check or swing valves require some sort of backflow to work properly, so that pressure to push the valve closed is more important than the particular orientation of the valve.
Intresting i have check vavles on my aquarium air lines think they work the same just with air i know if the power fails or i turn my air pump off they stop water going down the line destroying my pump
Thanks for watching. A check valve prevents water from draining back down the pipe it is not a tool to solve airlock. To fix a problem with airlock air will need to be effectively released from the system. This can be done through a fixture somewhere in the system or a bleed valve.
ive been told to remove my check valve on my septic system after the effluent pump so that water in the pipe doesnt freeze in winter. The pipe volume is not enough to cause the pump to cycle again. Any thoughts.
Thanks for watching. Cold weather does change things and if the volume of water isn't enough to cause the pump to cycle then it shouldn't be a problem. Depending on the volume it will run a little more frequently than normal but likely not enough to create issues.

My landlord might need to have one of these installed? I've been in the basement apartment for 4 years, but recently when I use the kitchen or bathroom sink, the main drain overflows, but not the toilet or shower. Any suggestions please?
Hi Heather, thank you for watching! Slow draining can be caused by a venting issue or a localized blockage in one of the drains or shared pipes. For venting issues we have an animation describing this in this video th-cam.com/video/zGofkKOP2SU/w-d-xo.html It might help you visualize it.
Thanks for watching.For life expectancy is difficult to say it really depends on the application, the pressure and how much it is used. An 2nd check valve will add redundancy but like every elbow in the system it will contribute to the friction inside the system. If the pump is adequately powered this should not be an issue.
@@AmreSupply thanks for the quick response. I was thinking of a second valve outdoors to keep critters and rodents out the pipe but now I'm thinking in winter times the check valve flap could freeze shut. I might just put a screen on the pvc located outside.
Hi Anthony, thanks for watching. This depends if your pump in your well has a check valve or not. If it doesn't have one then its often still beneficial to use a check valve between the pump and pressure tank.
Thanks, actually im having issues on my booster pump and pressure tank. Reading blogs, i think its water logging, does it something to on their location? Booster pump and pressure tank are situated underneath the storage tank. Hence, there will be flow of water to the tank even the pump is off causing water logging. Just my thoughts.. maybe an expert like you can provide guidance to me... thanks
@@anthonytorcedo5175 Yes the location of these can matter and in some cases a check valve is needed between the Booster Pump and pressure tank and after the tank as well. I would recommend contacting a plumber to take a closer look at this as its hard to give specifics as it depends on a lot of factors.
Thanks for watching! That is an excellent question. Check valves and backflow preventers can create problems with water heaters due to thermal expansion. In some cases this can cause the relief valve to open intermittently. This is explained in this short video th-cam.com/video/E1B-jSamx5Q/w-d-xo.html If you are curious we have a whole playlist on water heaters including troubleshooting and repairs: th-cam.com/video/BHUPFLbb8NY/w-d-xo.html
Hello i have a 7.5hp centrifugal triphase water pump. Now I get water from a spiral rubber and foot valve drill. The water level is about 4 meters deep. Now I would like to put a check valve on the surface of the tube. My pump will be able to draw 4 meters of air between the pump and check valve to bring the water up;
Hi Alexandros, thank you for watching. Unfortunately pumps used for agriculture is outside of our direct experience, so we can't make any specific recommendations. Its worth contacting a local industrial supply shop. As well I'm sure if you do some digging there are likely some forums or website with farmers that have a similar setup as you who could help answer some questions.
the weight of the water "does not close the check valve". The check valve is opened by the suction of the pump. The check valve has a spring which closes the valve once the suction of the pump turns off. If you depend on the weight of the water to close the valve, you have installed the valve backwards.
Thank you for watching. There are gravity closing check valves that work even without a spring. As well swing check valves still work even without a spring as any backflow will push the flap close. You are right that the spring will help close it. In the case of the sump pump, if the check valve was installed backwards the pump would not drain the sump basin as the check valve would prevent water from flowing out through the pipe.
Thanks for watching. A little bit of water sitting above the check valve is not problematic, and it will prevent the water from flowing back down and triggering the pump again. Without a check valve the pump will run a lot more than what is necessary.
I'm glad I watched it to the end. That is a magnificent mustache!

How to remove the water above the check valve for service? My sump pump check valve is low on one pit and high on another any reason for this?
Beautiful explanation
Thank you Nader!
Thank you sir, very good description to a layman like myself! Happy New Year!

Thanks for watching. We haven't created any videos on spring valves yet but we will keep that in mind.
My hand pump is facing difficulty in gaining pressure to pull up water. The problem due to check valve or washers like cup washer / plate washer?
Thank you for watching. There are a lot of variables so it is hard to say what is the problem, but yes it's good to check all washers to make sure it has a good seal.
Does a bad check valve causes air in the system like sputtering and choking, especially in the morning?
It depends on how it fails. If the check valve is stuck closed then it might sputter. If the check valve does not close properly then water will rush back into the pump and it will run more frequently.
What is the effect of backflow to motor of pump? Please explain it, thank you sir
Thanks for watching. Backflow will reduce the motor life as it will be running more often to remove the same amount of water.
Quite Informative. Thank you!
You're welcome, we're glad that you found it helpful!

There is still litle waterhammer when i use one check vale in inlet pipe .

To fix water hammer, tighting the mounting clips on any pipes can reduce the noise. Installing a dedicated water hammer arrestor will create a cushion for the water, reducing the shockwave. A check valve will not act as a cushion as this is another hard stop in the system.
So what does the duckbill do inside the check valve?
There are different types of check valves. For a sump pump it will have a hinge and a disc that closes when water is pulled back down by gravity.
The duckbill valve is a flexible one-piece sleeve in the shape of a duckbill which will open when the water is flowing in one direction, and enough back pressure will force it to collapse inward and close, preventing back flow.
So the check valve must be installed before or after the motor pump?
In the examples in the videos it's after the pump because gravity would pull the water back and force the pump to run again.
Excellent video thanks
You're very welcome!
Very clear ! Amazing
Thank you Rohit! We're glad you found it helpful!
Thank you for this video, so helpful Yes.
You're welcome!
So it's the same as a backflor preventer?
Yes, a check valve is a type of backflow preventer but has a different appliacation.

Can swing check valve can be installed vertically
Thanks for watching. Check or swing valves require some sort of backflow to work properly, so that pressure to push the valve closed is more important than the particular orientation of the valve.

Intresting i have check vavles on my aquarium air lines think they work the same just with air i know if the power fails or i turn my air pump off they stop water going down the line destroying my pump
Thanks for watching. Most check valves are not powered and will still work without any electricity.
to solve air lock either use check valve or bleed valve ?

I just want to know , what happened if there is no gravity? In other words, how will be the flow if check valve is closed in this condition?
For check valves installed horizontally, a spring is commonly is used to keep the valve closed, so no gravity is needed.
the weight of the water "does not close the check valve". The check valve is opened by the suction of the pump. The check valve has a spring which closes the valve once the suction of the pump turns off. If you depend on the weight of the water to close the valve, you have installed the valve backwards.

But doesn't anyone think once that check valve closes water still is sitting above the valve ? ....
Thanks for watching. A little bit of water sitting above the check valve is not problematic, and it will prevent the water from flowing back down and triggering the pump again. Without a check valve the pump will run a lot more than what is necessary.
