Plumberartarmon Pipe ReliningWhat do I have to know before choosing pipe relining as the repair of choice?

Pipe relining being new to the industry has been submitted to a lot of tests and trials. Before even applying it to the field and making it an option for the customers, the manufacturers made sure that there is a substantial amount of study that can support the effectiveness of their product. Here is a small list of the things you need to know about pipe relining before actually using it:


    1. Independently strong.

The cured-in pipe does not rely on the host pipe. It does not require any assistance or need the host pipe for any structural strength contribution. What the pipe needs is the structural form it can get from the host pipe but once the pipe is already cured in and solidified, it will not need the host pipe to hold up so it can do its job.

    2. Bridge pipe gaps.

Because the new pipe is continues and does not need fittings for corners, its surface does not have tiny crack or minuscule holes that the root may infiltrate. Also, since the reinforcement is from manhole to manhole to manhole, the new pipe can bridge any gaps or missing parts of the pipe due to aging, corrosion or breakage.

    3. Different pipe diameters can be relined.

Pipes differ in diameter depending on the usage it will be accommodating in a household. Pipes from the size of 8” to 69” in diameter can be relined as reinforcement. This limitation is being lessened each day by studies and other means of research for this type of pipe repair.

    4. A practical alternative.

Monetarily, pipe relining will help you save up when you reline your plumbing pipes. This method will save you from having to buy numerous things and materials to be used in excavating your pipe while you also have to pay for an architect to bring your lawn to its former glory because guaranteed that after the digging and repair is done, your lawn will look like a bombing site. Pipe relining saves you a lot of money.

    5. Non-intrusive method.

You will not have to excavate your pipes that are buried across your lawn or embedded in your house and foundation walls. The pipe relining’s new method will only require two holes at most to get the job done.


    1. Reduces pipe diameter.

The pipe liner is situated inside the damaged pipe which means that whatever the diameter of the host pipe minus the thickness of the liner when it is cured in will be the diameter of the inside of the new pipe.

    2. Not universally applicable.

There are cases when even pipe relining will not save your pipes. Here are some of those instances:

  • The pipe has lost its form. Irregularly shaped and bent pipes are not advisable for pipe relining since the liner should be placed inside the pipe and no one knows if the inside is still capable of housing reinforcement.
  • When the requirement is to increase pipe diameter for better supply flow.
    Chemicals around the pipe, externally, may corrode the pipe liner or, worse, complete dissolve the epoxy compound.
  • When the temperature of the external and internal surroundings of the pipe is too high for the compounds to stand.
