Traditionally, all sewers were replaced by trenching down to the pipe and replacing either
just the failed section, or the entire line if it all looked bad.
A few years ago new methods started appearing on the market, from pipe-lining--which lines
the inside of your existing pipe with a new plastic surface,
to pipe-bursting--which forces a bursting-head thru your old pipe, causing it to break into
pieces as a new pipe is dragged along after the bursting head.
Both pipe lining and pipe-bursting can work, but neither method will correct the problem if
your old sewer had a sag, a low spot, or a flat spot that
allowed material to gather and clogs to form. Both methods leave the new sewer following the
same path as the old one, including all of
the flaws that the old path had. In addition, pipe lining depends heavily on the quality of
the lining material, and its durability over time. We've seen
some lined systems work really well over the years, while others have failed
catastrophically after a very short time.
An even newer method in use today is called directional boring. In
this case, a boring head
is run thru the ground from the beginning of the length to be replaced, ending just
outside your house, where it can be tied into your existing
drain system. Our personal opinion, backed by decades in the industry, is that
trenchless methods can work well for water services, but we do
not like them for sewer replacements. We can't see what is under the ground. If
the boring head hits a rock and is deflected, you could
be left with a sag or a bump in your sewer line, which is guaranteed to cause
trouble in the future!
Ultimately, our recommendation will depend on the exact details of the situation
we're facing, the type of soil and rocks we'd be going thru, how deep
the pipe is, what's around it... We can't make a recommendation without seeing the
situation in person. Give us a call at 541-343-9339, we'd be happy
to look at it!
In the meantime, here's an interesting discussion on Angie's List that describes a
few of the pros and cons of the various techniques in common use today.
PLEASE don't flush antibacterial wipes!
TL,DR - Experts tell us that we should only put two things down a toilet - human waste (of course) and
toilet paper. NOTHING ELSE. Here's a helpful List to print out and post near your toilets.
Put a Vent In It! A blocked vent pipe can cause almost as much trouble as a
blocked drain! Here's what to look for if your drain starts surging and gurgling.
Don't flush that! Out of sight is
not out of mind when your drains clog! Some things should never go down your drain! Here's a helpful List of Do's and Don'ts to print out - from Petersen Plumbing.
