Sewer line crack....


Okay...so my 2" sewer line (I have a partial ejector pump) is leaking under my drive way. I had 3 bids to fix it. the first one was crazy expensive and did not cover fixing the driveway. The other 2 both suggested running a 1 1/2" through the existing 2" line. That way they dont have to cut up the driveway.

Do you think this will be okay? Or should I have them bore a hole under and install the correct 2" line?

Stick with 2". Find a plumber with a Borzit boring system. No need to tear up the drive. Make sure he uses a heavy grade pipe for under drives. Chances are the original pipe wasn't strong enough for under drives.

EXACTLY

Even if you have to buy a Bor-it. It will be cheaper than replacing the drive way

Update....Okay I talked to the plumbers about boring a hole under the driveway (15ft or so across). the plumber said he does have a boring machine but asked why I would want to go that route when a 1 1/2" through the 2" will be acceptable. The old pipe under the driveway is a 2" 40 class? Is what he said and he will be using the same grade. He said I shouldn't have any problems and said if I do he will come back and bore less the charge of this service call.

I am also in the process of selling my house so every penny counts but I dont want to screw the next homeowners. But the price difference is so extreme

Whats your thoughts?

Until you said this... my thoughts were that if you are going to bore a hole under the driveway, don't make it a hole big enough for just a 2" pipe, make it big enough for a 4" pipe so that it can be a sleve around a 2" pipe.

There's no reason why a 2" Sch 40 pipe being used under low pressures should start to leak... unless it wasn't installed properly, like being placed in a sand bed before getting covered up by a driveway. It makes me think that the reason the pipe started to leak was that either poor backfilling practices were used, or the pipe isn't deep enough and some how the pressures of traffic in the driveway caused the pipe to break.

So to make sure these sorts of things don't break the new pipe, I would install a sleave pipe first and run the plumbing pipe inside of it. That way if the same conditions still exist, the sleave might crack, but until it collapes your plumbing pipe remains safe.

update...the pipe looks like the driveway is resting on the pipe. They are starting to excavate and it doesn't even look like they packed in clean fill. There are rocks the size of bricks...
