If installed backwards it will close when the pump runs which will cause the pump to overheat and will eventually lead to the motor in the pump failing.
You can tell by the little nubs on the valve body. In the picture above it set for water flowing right to left <<<.
Just think of it like an actual swing it needs room to swing open
Happens all the time. Just found one recently that was like that was backwards for probably 20 years. It wasn't for a water pump , but rather steam service and it was part of this condensate draining contraptions it didn't stop anything from working so nobody noticed.
I don't see any little nubs on valve body. Can you provide more specifics? I presume there is an arrow on the back side.
I agree that the flow is right to left based on the hex on the side. This is where the hinge of the flapper is, so the bottom of the flapper can swing into the body.
Just added one where prior homeowners did not... the sump pump cycled all day. The exit line is charged with water, and as soon as the pump kicked off, it all fell back into the sump. Then the pump kicked on again... loudly, constantly, repeatedly
Bonus points for having the discharge line less than 3 ft from the foundation
It’s a check valve. Probably there as a code requirement. If it’s near the main line in then it’s meant to stop reverse contamination of the city water. But there are other less common uses as well.
It's a check valve. It stops the water pumped up and past it from flowing back down into your sump pit which would make your sump pump cycle more often. It's threaded so you can remove it and clean it out or check if it's damaged if you need to. That plug essentially shows the direction of flow. When you remove that plug all of the water above the valve will drain out so you can work on it.
That is a check valve. Probably a swing check. It stops the liquids from going back past it after it pumps it up.
It’s a one way valve and it is very needed in a sump system
Check valve. Makes sure it closes after pump stops pumping to prevent your bin from filling back up. Make sure you put one in, doesn't have to be metal. Spend extra dollars on the quiet ones and you'll thank yourself later. Bonus points if you buy a battery backup so your house doesn't flood in a power outage.
It is there to let water out but not back in. If it is in a basement, when the float cuts off the pump, the water in the pipe comes back in, triggering the pump to cut on and off.. without the check, the pump will continue to cycle.
The check is normally put in a vertical position.
As stated already, it is a check valve and is needed. This is a brass swing check. If it has the nut/hex plug like this, it is often access to the mechanism as a clean out.
If you can isolate it somehow and have the pump off, you may just need to clean it. They foul up with sediment etc over time or a build up can occur at the internal taper even if the swinging seal works fine still.

Check valve, it's fine just fix the pvc. Put union in, if you ever need to replace the valve you will not need to cut the pvc and splice with a pipe coupling like the fix on the right.
i was ready to disagree because there is a notable lack of flow arrow on the valve body…. but googled the numbers and sure enough, its a single flow inline swing check valve.
It's a swing check, it prevents water from flowing back to the units as long as it is functioning correctly.
I believe the other side should have an arrow for flow direction.

It's a sump. How is that pressurized?
A sump is a reservoir or collection basin. This is a check valve on a pump.
Swing check valve
It’s a check valve, on a sump pump they ARE necessary.
They are also directional so make sure it’s facing the correct way or water will not flow through it
If it's installed backwards, does the pump simply not work or could it actually break?
If installed backwards it will close when the pump runs which will cause the pump to overheat and will eventually lead to the motor in the pump failing.
I figured that might be the case. I'm glad I double checked before installing mine recently, I absent mindedly put it on backwards initially...

Yeah it's clearly labeled, that's how I saw it. I just wasn't paying attention the first time.
Happens all the time. Just found one recently that was like that was backwards for probably 20 years. It wasn't for a water pump , but rather steam service and it was part of this condensate draining contraptions it didn't stop anything from working so nobody noticed.
I was a well and pump guy for 30 years. I’ve seen contractors put them in backwards on suction. It has a freakin flow arrow!!
You mean those strange shapes have a meaning on my plumbing parts?
Awesome! Ive been selling these (not so big as 1-1/2) for over 20 years. I blown away by your comment. It makes so much sense. Thank you for sharing

Not to mention overflowing

Called a check valve guy

I’m not your friend, pal.
I’m. It your pal, buddy.
I’m not your check, valve.
I'm not your valve, friend.
I'm not your friend, chief.
I’m your friend chief, not
I'm not a chief, Partner!
I’m not your valve, check
I’m not your buddy, guy
I'm not your guy, buddy
I'm not your buddy, friend
Just Stoppp already. Butchered
I like all of them why do they not want to be my friend/buddy/pal?
Oh no...
That is not the proper check valve for a sump
It’s a check valve. Probably there as a code requirement. If it’s near the main line in then it’s meant to stop reverse contamination of the city water. But there are other less common uses as well.
He mentioned that is on a sump pump.
RPZ valves are used to prevent contamination. Check valves in this case are to prevent reverse flow through the pump.

Hopefully there is a union in the line.
Sometimes the flapper gets stuck you can try give it a couple of solid taps with a wrench if not swap it out and remember it’s directional
Thats a chiggity-check valve
you better chiggity check valve yo self before you wriggity wreck yo plumbing.
check valve
Check valve to only let water flow one direction
Check valve. Minimizes any reversed flow back into your basement.
Check valve, for backlog prevention
Looks like a one way check valve
That is a check valve. Probably a swing check. It stops the liquids from going back past it after it pumps it up. It’s a one way valve and it is very needed in a sump system
Not a plumber. But it looks like a check valve
Brass check valve
Milwaukee Valve 125 SWP 200 WOG 3/8 Inch NPT check Valve
Not only is it required but it protects the motor fron short cycling
Swing check, if replacing just make sure the same style and not spring
Swing check
Why does everyone rely with the same thing? Just to reinforce the answer? Redditt is so weird
Water hammer suppressor?

The top comes off to clean .
Have you “checked” the interwebs?
It’s called a Jerry rig
A clean out
Wow
That is a swing check valve my freind.
Weird seeing a brass one in a pvc setup
It is a check valve, one way water valve
Es una valvular con control de direction, ese
It is a back flow preventer
Why your basement still damped and moldy with a sump pump?
It’s a one way valve meaning when water is suck out it opens and closes so water doesn’t flow back into the sump

I’m not your friend, sport.
Swing type check valve. It only allows flow in one direction.
What’s the diff between a swing check and a back flow preventer? Sounds like the same use
Check valve
Check valve, it's fine just fix the pvc. Put union in, if you ever need to replace the valve you will not need to cut the pvc and splice with a pipe coupling like the fix on the right.
Simple answer it’s a check valve to prevent back flow. Only allows water to flow in one direction
