A week ago, on of my neighbors had his sewer back up into his
basement. His house was built at the same time as mine (about 90 years
ago). My wife pretty much ordered me to do whatever it takes to
prevent this from happening here. Coincidentally, I received a coupon
from a plumber for a $39 camera inspection of my sewer pipe. THAT is a
very good price, I know people who have paid over $200 for that
So, the guy came, and he was friendly, knowledgeable and thorough. He
spent over two hours looking and explaining. Long story short, the
pipe is fucked. There are no tree roots, but there are major deposits
and lots of rust. It's likely that the pipe is paper thin along its
bottom. There's standing water in some places (though not very deep),
and when he pulled out the camera, there was dirt (like dirt from the
ground) on it.
Digging is not a very good option, as there is a large (and I mean
LARGE) tree at the curb line, right above the pipe. Either the tree
would have to go or they would have to open the street, which runs
into over $10K just for the permits and insurance and paying two cops
$65/hr to direct traffic (we see maybe ten cars a day on my street),
The other option is to hydro-blast the crud out - they can vary the
pressure from 10Kpsi to 50Kpsi which will leave the pipe clean and
even more fragile. Then they would reline it with this stuff:
which leaves about a 3/16" very smooth plastic wall inside the pipe.
This involves jackhammering in two places in my basement - one to
bypass the whole-house trap wich is no longer required by code, and
the other to gain access to the pipe just past the main stack. There
is no digging required outside.
All this comes with a lifetime warranty, transferrable once, and a
price tag of $7700. It takes a full day (he says there are three
trucks and six people here all day), and then its done.
Good idea? Bad idea? Run like hell?
