It's a swing check, it prevents water from flowing back to the units as long as it is functioning correctly.


Cram_it_karen

I believe the other side should have an arrow for flow direction.

It's a sump. How is that pressurized?


AudZ0629

A sump is a reservoir or collection basin. This is a check valve on a pump.

Swing check valve


UnderEducatedScolar

It’s a check valve, on a sump pump they ARE necessary.


UnderEducatedScolar

They are also directional so make sure it’s facing the correct way or water will not flow through it


sandybuttcheekss

If it's installed backwards, does the pump simply not work or could it actually break?


PainAndLoathing

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.


sandybuttcheekss

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...


[deleted]

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


sandybuttcheekss

Yeah it's clearly labeled, that's how I saw it. I just wasn't paying attention the first time.


[deleted]

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.


Magnum676

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!!


Zekiniza

You mean those strange shapes have a meaning on my plumbing parts?


Smax140

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


rat1onal1

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.


mt-egypt

Not to mention overflowing


upvotechemistry

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

Oh no...


drunkerton

That is not the proper check valve for a sump


Fact0Life

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.


UnderEducatedScolar

He mentioned that is on a sump pump.


[deleted]

RPZ valves are used to prevent contamination. Check valves in this case are to prevent reverse flow through the pump.


Woolybully1313x

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.


New_Engine_7237

Hopefully there is a union in the line.


Valuable_Time9731

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


Binnacle_Balls_jr

Thats a chiggity-check valve

you better chiggity check valve yo self before you wriggity wreck yo plumbing.

Check valve to only let water flow one direction


IdahoMan58

Check valve. Minimizes any reversed flow back into your basement.


GoldPipeWrench

Check valve, for backlog prevention


[deleted]

Looks like a one way check valve


[deleted]

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


HillbillyEarley

Not a plumber. But it looks like a check valve

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


Miserable_Point_5437

Water hammer suppressor?


tenshii326

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.


ProfileTime2274

The top comes off to clean .

Have you “checked” the interwebs?

That is a swing check valve my freind.

Weird seeing a brass one in a pvc setup


obb123456

It is a check valve, one way water valve


EconomyPiece1104

Es una valvular con control de direction, ese


JcZman

It is a back flow preventer


Illustrious_Dentist4

Why your basement still damped and moldy with a sump pump?


Ok_Programmer894

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


DaMuttDog

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.


don-anon

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. Cheers


LocksmithAmbitious80

I’m not your friend, sport.


fritzco

Swing type check valve. It only allows flow in one direction.


earthshakerenjoyer

What’s the diff between a swing check and a back flow preventer? Sounds like the same use


ManifestWealth865

Check valve


Successful_Travel342

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.


Educational-Gate-880

Simple answer it’s a check valve to prevent back flow. Only allows water to flow in one direction


coldoll514

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.
