What is Trenchless Pipe Lining?
Pipe Lining is also known as CIPP (cured in place pipe) or epoxy pipe lining. Pipe lining is a method in which a felt tube gets saturated in
epoxy. The felt tube is then placed into your existing pipe. Once in place, a balloon is inserted inside of the felt tube. The balloon is
inflated, pushing the felt tube against your pipe. Once in place, a balloon is inserted inside of the felt tube. The balloon is inflated,
pushing the felt against your pipe. The epoxy will cure in about an hour or so. The balloon is deflated and removed. What's left is a new
pipe within your existing pipe. Pipe lining only requires one access hole.
What about "NO DIG" Replacement?
No Dig Pipe replacement is a term used to describe Pipe Lining. There are times where a drain can have a pipe liner inserted through a
clean-out or vent. However, this is for larger pipes usually in commercial properties. In residential properties, some digging is required.
There are times that excavation is unnecessary, but that is only about 3% of the time. Before a trenchless repair can be completed,
access to the pipe is essential.
Why can't you access the pipe through my sewer vent or go
through my toilet?
A toilet is never sufficient access because of the number of turns the drain makes before heading all the way out. Most pipe liners cannot
be inserted through pipes that have more than two turns. Through trenchless pipe lining, a sewer vent may be adequate access.
However, in most cases accessing the vertical piping is not as effective as accessing the horizontal piping. Moreover, as you know,to
access horizontal drain pipes you will need to dig.
What about my outside drain clean-out?
The clean-out may be sufficient access for pipe lining. However, only about 3% of the time. In older homes, most clean-outs lack the
directional fittings that allow a pipe liner to run through them. Pipe Lining through a clean-out can be achieved through a four-inch
ABS/PVC cleanout. So, if you do not have a clean-out, don't worry. We can install one for you.
Does Trenchless Sewer repair work if I have root intrusion?
Yes. The roots do need to be removed first. This can be achieved with Root cutting drain equipment. Once the drain is clear of roots, a
pipe liner can be inserted for a permanent repair.
What happens if the cast iron drain under my slab is corroded or
Many plumbers diagnose scale build-up within cast iron to be the start of a collapsing pipe. This is usually not the case. If your cast iron
pipe has scale build-up, it can be removed through a de-scaling process using specific cast iron drain equipment. In many cases, your
pipe just needs a de-scaling, not a trenchless sewer repair.
Does pipe lining reduce my current pipe size?
Being that a pipe liner uses the host pipe to provide its shape, the diameter of your pipe is reduced slightly. The liner material is roughly 1/4
of an inch thick. Many people ask-"Does the pipe reduction reduce flow?" No, it does not. Because the pipe is seamless, it will actually
increase the flow rate of your pipe. With no joints in the new liner, there is less friction.
Is the city responsible for my sewer line in the street?
This question is best asked directly to the city. Although there are many times the city takes care of problems located on their side, we
also see many cases where the city does not take care of issues that reside under the street or on city property. From our experience, in
most cases you are responsible from the sewer tap (at the main sewer) to your home/business. Closing and excavating within a street
can be an extremely expensive proposition. Pipe lining will save you thousands of dollars.
What happens if the bottom is missing in my cast iron drain?
Not a problem for pipe lining. A pipe liner can successfully rehabilitate sewers with extensive material loss. Pipe lining was specifically
designed to repair drain pipes with cracks, holes and missing sections. There are times where the material loss in the cast iron is too great,
and a pipe liner may not be capable of repairing, but that is only about 5% of the time.
Trenchless Sewer Repair VS Traditional.
A trenchless option is not always going to be the better choice. There are times where a traditional sewer replacement is a better
option. If the pipe is far too corroded for a successful pipe liner installation, then a regular replacement may be the best. This question is
best answered after your particular sewer pipe has been evaluated via camera inspection. This will help the us determine what method
How much does it cost to replace or reline a sewer?
The average sewer replacement in the City of Pittsburgh and surrounding neighborhoods will range from $3500 to $15,000. There are so
many variables that go into pricing, and not all projects are going to be equal work. In order to get an accurate price, a technician will
have to visit the jobsite, evaluate the overall condition of the existing sewer via camera inspection and take into consideration all of the
of our professionals any questions that you may have.
