You should bear in mind that the city sewer "tap" may be as deep as six
feet which amounts to a serious trenching job.
On our current room addition project we opted to route the PVC from the
new bath to connect with the existing house-to-city sewer (under the back
alley in this instance) since the city sewer was almost eight feet down!

My city sewer is 11ft down. I've got a 1/2 bath and a floor drain in the
basement
drained by gravity.

The 4" PVC line exiting my house has a pair of 45's on it. No problem with
doing it that way, so long as you observe proper slope and whatnot.

Mail Man Bob,

As I posted in my reply in abpw, take a look at www.maxlinerusa.com.

Hope this helps.

Peter.

Thanks. I did -- looks like a clever idea, but way too complicated or
expensive for what I'm doing. I'll look for a flexible thin wall pvc or
something similar to that for this short run.
