ok, that's the ' seeking its own level ' rule of water,,, IF i were you, i'd be putting in a sump & pump,,, we get sumps w/bolt-down covers from ferguson & always use zoeller m-53 pumps [ no $ interest - find 'em on ebay ] never have any trouble.

just be sure to drill 5/8" holes in the sump up to about 8" high [ 30 holes should do it - sides AND bottom ],,, surround the sump w/clean 57 stone 6" thick,,, line excavation w/soil filter cloth,,, IF the soil's heavy w/silt, you might need a pump stand to prevent excessive impeller wear,,, pump bushing & check valve for 1 1/2" pvc discharge piping,,, got it ?

good luck !

The water in the ground and the water in the pipe are two different although slightly related things.

That hole is where the floor drain used to be, you're supposed to have one for spilled water to escape. But the sewer system in the neighborhood is not working, so the basements that are at the critical level flood.

Your system allow your basement not to flood until there's more water in the neighborhood system. So, your basement doesn't flood as soon, but your neighbors' basement do.

Some cities do not allow those stand pipes cuz they feel you're cheating and making it worse on your neighbors. It's like raising your house a foot or so.

jeep, evidently jaz thinks the pipe was capp'd 'cause it smell'd like sh**,,, somehow i think you wouldda post'd that IF it were the case, right ? sewer system MAY not be ' tight ' but there'd be some indication of a fault & odor is usually the 1st sign

' It's like raising your house a foot or so. ' huh ?

JazMans explanation is right on,if you want to keep water out of your basement,the stand pipe is the poor mans answer,problem is if a section of the sewer pipe should fail it can cause your floor to rupture,years ago I had the same problem you have now, but I installed a check valve before the pipe entered the house and that solved my probem,more than likely wasn't legal but the basement didn't flood anymore.

There isn't a sewer smell from there at all. Would the standing (i.e. standing) water indicate there's a trap down there?

From what I'm getting from you all, this hole ties into either;
  1. the sewer
  2. the footer tile
  3. nothing; open to relieve hydrostatic pressure
And before anyone else suggests it, yes, I have a sump pit. LOL!

As far as why there's a standpipe, ask the neighbors if they know. Hopefully they can tell you.

You pull the pipe between storms and use it as the floor drain. You can even install a drain grate over the hole. You install the stand pipe before the heavy rains to protect against the drain backing up.

Around here basements have at least 2 floor drains. One or more that ties to the sewer taking the water away to be processed, and one that drains into the sump well. This drain leads to the city line shared by your neighbors.

itsreallyconc in #19 above misunderstood my thoughts about the pipe. I never thought and never said anything about an odor. The only smell might be stagnant water after a while. And yes.....it is like raising the elevation of your house a foot or so.

Read what oso954 said,it's a floor drain and yes there's a trap to keep the sewer gas out.

Why do you have 3 sump pumps, and what are they pumping???

THREE ? ? ? IN THE SAME SUMP ? ? ? we couldn't fit 2 m-53's into a sump so i gotta think your pump(s) are too small to handle the waterload,,, just placing a sump & pump MAY create a condition known as ' scour ' during which passing sub-surface water will wash fines out of the soil supporting your home's very fine floor,,, evidently i'm outnumber'd w/the standpipe thingie but i've never seen 1 in nj, ct, ny, pa, de, or ga

got it, jaz - you were thinking ' storm sewer ', not sanitary

i've never seen any pro place 2 pumps in a sump let alone 3 [ battery backup excepted],,, sumps & pumps are meant to be separated & usually fed by delivery piping ,,, you sound fairly handy - why not call in a waterproofing company for an on-site inspection ? most of us offer them freely in hopes we can ' close the sale ',,, after all, we got boat pymts to make

ps - 1 more thing - forget any flexible discharge line - use rigid pvc only for best results

I think the idea is you have more than one pit. This way the water is collected in a more distributed fashion.

We've got two in the new house and the one on the 'uphill side' tends to run a bit more after it's been raining a bit. Both eject outside to the dry wells (on the downhill side of the house). They're tied into a drain tile system that wraps around the whole house down at footer level. Both have bolt-down lids on them with some gaskets. There are screw-in inspection ports to allow for an easy look-see from time to time.

The idea here is control the water. Make it easy for it to get to the pumps and then have them get it all away quickly.

So the question is where is your current pump setup sending the water?

I am always having problems with my subpumps too so i understand having as many backups as possible.
Jaz mans answer makes the most sense if you can verify it goes to storm water drain. Do you have storm drains on your street?
This is just another reason why I want nothing to do with city living.

Long story, but here it is... We bought the house (09/12) as a foreclosure, as is, without a disclosure. The pump was too small pump and didn't function correctly. itsreallyconc, the flex line you see is the original discharge line. The inside diameter is 1", which as I found out later, is too small. I didn't know any better, so when I bought a 1/3 hp Gould, I hooked it up to what was there.

The set-up seemed to work OK, and all was good until 07/13 when we were hit with a flash flood. 5" of rain in one hour, on top of already saturated ground. That is how we found out that our house is at the lowest point of elevation in our neighborhood. This is a tri-level house, so the crawl space and lowest floor are on the level, with the crawl being about 2" lower. I had 18" of water in the family room. During the following clean up, I discovered some rot on the furring strips and a water line stain about 8" off the floor; this house has flooded before. I also found a second sump pit under the stair case that goes from the family room to the garage, so yes, wkearney99 I do have a second pit, but it is not connected to any drain pipe. (itsreallyconc, you mentioned drilling holes in the tub, that is the way this pit is set up, so I assume this is just collecting ground water. It does not get nearly as much water as the one in the crawl space.)

All remodeling stopped until I could figure out how to finish that room correctly, i.e. without having to worry ruining what ever I put in there. That search is what brought me to DIY, but going off topic here...

I realize that no pump system is going to be able to stop a flash flood. I bought a Watchdog battery backup pump, but didn't install it. Anyway, I was still taking my time figuring out what to do, when we flooded again in 12/13. Not a flash flood, but enough rain that NOAA had issued a flood warning. The pit filled faster than the pump could discharge. (1" outlet!) That's when I stopped procrastinating and came up with my three pump / 2" outlet idea.

itsreallyconc, I knew I didn't want a pump that is too small, and I thought the 1/3 hp was just that. So, I took my dimensions and idea to a local shop called Water Equipment Co, decades in business, they do plumbing & related and that is all. I was going to use a 1/2 hp Zoeller as the main, I was told it was too powerful for the pit size, it would “short cycle,” the pump will start and stop frequently, which can cause premature pump failure.

So what I ended up with; if you look at the picture, 1/3 hp Zoeller (blue) as the maintenance pump, to a new 2" outlet. I kept the 1/3 hp Gould (stainless) as the secondary, and since it already had the 1" out and check valve there, I left it connected to the original outlet. (I will eventually get rid of that flex!) The Gould is set to switch on if the pit gets about 3/4 full, and has yet to be tripped. The third pump is a Watchdog with battery back-up (yellow) to a new 2" out and is switched on if the water hits the top of the pit. According to the ratings on the pumps, if all three were to operate at once, they can move 90 gallons a minute, give or take. All of this water goes out to a culvert which is about 50 - 60 ft. from the house.

As for the pit itself, again itsreallyconc, you mentioning the holes, there just two in this pit. I have yet to see any water come into the pit from them. But water comes in from somewhere else, other than the tile, so I am guessing the pit has holes at the bottom....? The tile inlet is hard to see in the picture; it's behind the center PVC outlet.
