Ok I posted a pic a few weeks ago of my floor drain,,after heavy snow melt and then rain, water wants to back up thru my floor drain,,,if you look at the pic in my below post from a few weeks ago you can see behind the drain is a cleanout hub sticking out of the floor,,,,i put a rubber plug in the floor drain and the cleanout hub is plugged,,,
Should I put in a stand pipe instead ? I just didn't know if having it plugged would build up pressure and buckle my floor or wall...
If so how high of a stand pipe ?
And I have a pump up toilet (saniflo) and also a shower that goes into a small above floor sump with an automatic utility type pump,,,could I just come up with a stand pipe about 12",,,then 90 it to the shower sump....so IF water built up it would run to the sump ? Or will the water not go up 12" above the floor thru the pipe ??
Guess I don't understand how high water could go up the stand pipe....

1) leave it plugged
2) install a standpipe in the cleanout and go up 12' the 90 to my shower sump ?

Good question,noone seems to know where this drain goes,one guy said there is an old septic tank right outside the wall.
Well if there is the tank would be 6ft below grade,so that's probably not true.
Then someone said maybe it's a drywell built when the house was built in 1955
This is only an issue when heavy snow melts,we had 28" a week ago that melted and rained in 25days
Then another ft yesterday
I have it plugged right now

if you take the plug out of the cleanout, do you get any smell coming back?
i ask because if you have any concerns about backpressure, remove the cleanout plug and screw in a male adapter and a standpipe there.
at my sons house, he had about a couple of inches of head pressure under his cement floor. all it did was force itself up thru the cracks in the floor causing wet spots.
when he first bought the house i drilled a hole in the cement and water bubbled up like a drinking fountain. laugh.. i had to go outside and cut a branch off a tree and pound it into the hole..

no smell really,,,if you stick your nose in it kinda like just damp metal,,,that why I was going to go up about 8-10" then 90 a pvc pipe to my shower sump so if it did rise up it would get pumped out....I called rotorooter and they want 300.00 for the first hr to put a camera down it...
Again its like 6ft below grade so its not the old septic,,if its an old dry well it doesnt seem like me lugging it would hurt anything but I don't know that's why this post,,,
Hope I get some helpful responses....

in our own ways, everyone here tries to be helpful.
some question asked can be answered directly and accurately.
some rely on years of experience to give an educated guess.
some have us scratching our head saying "i have no idea but maybe someone else will"..
so, put me in category 3.. i wish i could be more helpful but i can't..

lol ,,,I hear ya.....im still tempted to try my idea of a stand pipe going into my shower sump,,,the pipe would be about 8-10" high,,,,
But id still like to know where this thing goes,,,,so I may have to pay the 300.00 for the camera job,,,if I plug the pipe it doesn't seem like it would buckle my floor if the water was inside the pipe...
Humm,,,my head has been scratched too

ok I decided to try my idea,,,I got a 2" male threaded adapter, bushed it to 1-1/4" so the 1-1/4" pipe comes up out of the hub about 9"...then 90's and goes about `14" horz. to my shower sump,,,then 90's into the shower sump...so if water backs up I ASSUME it will not let it creat too much pressure and it will run into the shower sump and be pumped to my soil pipe...
Think it will work ?

my son's house now has 3 sump pump pits all with battery backup.
he spent thousands to have his inside basement perimeter broken up, dug down and perforated pipe surrounded by gravel all leading back to one of the sump pits.
his is the last house on a dead end in street. bordering his back yard is a gully/stream which runs water about 2 weeks out of the year. it would be a simple project to have a backhoe dog a nice deep trench from his foundation and fill it with gravel to lead the water away. but the conservation commission doesn't want ground water diverted to the stream. BUT it is OK for his sump pump hoses to send the water above ground to the gully. absolute lunacy..

wait till Trump is in then send a letter
All joking aside that's why I don't want to break my slab,,,,no real issues in 30 yrs here other than this pipe maybe 3 times in 30 yrs...
My neighbor never had any issue before, then they bump their garage out,,,so new footers dug etc,,,,now they have constant running sump pump,,,if power goes off or pump fails they are flooded big time...
So if the disturbed something when digging or what they have serious issues...
