Broke plumbing - do I need to rebuild the trap?

[BilldaCat]

So I was doing some digging, dropped the breaker bar, and it hit the connecting piece perfectly here. On the right is the pool shed, this plumbing runs from the diverter valve, through that pipe, under the house, and out onto the driveway and into the street.

Yes, the pool pumps water directly into the street. House was built in 1985, I didn't do it.

Instead of rebuilding this trap, is there any reason not to just saw the pipe off at the right before the elbow up, throw on a coupling, cut the left pipe the same height, and put the bend in there? That way this would be all underground, I could drop my condenser pad on top of it, and put the pool heater there.

Given the plumbing layout I'm working with, I don't think this trap serves any purpose, since the whole run is effectively a trap since it drops like a foot or so from the diverter valve, down into here, down again under the house/foundation, and up again at the driveway/exit?

Thanks!

I'm guessing it's looped in an attempt to break the gravity syphon if you accidentally leave the diverter on waste. If the exit pipe is below the pool water level, it'll flow once primed if the valve is open, until the pool water is as high as the exit pipe.

This runs under the house? Did the house get built after the pool? Strange.

So the pipe goes underground there on the left, then resurfaces on the right, right by the garage door. I don't think it runs out past the house then makes a 90 degree turn parallel to the house, otherwise it would have to cut/jog back to where the drain is. My best guess is it goes under the house between those 2 points.

The pool deck and driveway are about the same level I would say. Goes down a foot or so from the shed into the ground, out of the shed, down another unknown amount, then what I *assume* is under the foundation, then up, then out the driveway.



Front of house. You can see the exit pipe to the right of the garage door. Shed is out of sight to the right/behind the house.

Edit: I suppose it could - perhaps just very very close to the slab of the house and runs parallel under the stairs and all the way around.

Do you have a basement or are you on a slab ? Either way, I'd guess they went around the house and not under it. Many companies trench and very few mistle under stuff.

Split level, slab. Yeah, they probably did just trench very close to the house, but it still comes back up there -- so I don't *think* I need to rebuild the trap and can just go straight and down, but wanted to check before I go cementing pipe together.

Just don’t bury a removable coupling.

Yeah, I'm using schedule 40 PVC for the coupling, pipe, and pool elbow bend, going to prime and cement it. Not handy with plumbing but this seems about as straightforward as it gets. Wanted to make sure I'm not missing something.

Cut the left pipe right below the elbow.
Cut the right pipe between the elbow.
Get a socket saver for 7 bucks on Amazon. Ream out the bottom elbow on the right.
Rest should be easy replacement.

Yeah my only concern there is if I'd have enough pipe between the two elbows on the right to make a secure connection -- it's only like, a fingers width, not even.

The socket saver removes the remaining pipe from the bottom elbow. Use a new piece of PVC into the bottom (old) elbow.

Interesting - did not know that was a thing. Thanks!
