Please identify pipes

[Rookie24]

Hello. My basement is stubbed for a bath but I'm not sure which pipe is my drain. Can someone please tell what each pipe is starting from the gravel one near the wall in the picture.

I'm putting a large aquarium in my basement and need to know which one I can stick a hose in to drain my tank water during cleanings. Thanks everyone!

this is what i seee

Thank you Frodo!! I appreciate the clear explanation. Is it safe to simply remove the cap and drain away or does something else need to be done first?

 

[frodo]

do you have a sewage ejector in your basement to lift the waste up to the sewer?

I don't think so but I'm not 100% sure. Sorry, I don't have any plumbing experience. If there's a way for me to check just let me know. The basement is completely unfinished and I'm also on septic if that matters. Thanks!!

LOL...only way i know, stick a hose in the pipe and turn it on.

if it backs up in 10 minutes. rut roo!!

if not, your ok


question is, is the yard/ grass/ septic system, above the basement or below the basement.

lol @ rut roo!!
The septic is actually on that side of the house and below the basement floor.

Ok, So worst case scenario, I get a rut roo backup and need to break out the shop vac to clean up the spill on aisle 3 Or will I need to call a pro to drain that pipe if that happens?

evaporation..

sounds like your tied into the septic.

look up in your basement ceiling, do you see a 2'' pvc pipe or a 3'' pipe with a cap on it?

I wonder if they ran a future vent for your future bath room.
is their any other plumbing in the basement?
that might have a vent.

Yes. There are two 3" pipes running up to the main floor and down into the slab. The one in the new picture basically runs to the main bathroom and the other 3" is on the other side of the house connected to kitchen, laundry and master bath.

Here is another picture of the 3" running up to main bathroom.
