FAQ: If the diameter of a pipe decreases with pipe relining, does this affect the flow?

Let’s talk about pipe flow.

When relining any pipe, drain, or sewer, the diameter naturally decreases due to the new robust epoxy resin that is installed on the interior of the existing, damaged pipe

Logic suggests therefore that the capacity of the pipe or flow would in turn decrease, right? Not quite.

This is a question we’re often asked by customers and many are surprised to learn that independent studies have shown relining actually increases the flow of a pipe. This is due to its new smooth internal lining, that in contrast to old clay pipes, prevents calcification and deposits from building up. 

Whilst diameter can be restrictive in some instances, pipe flow is primarily determined by friction. Therefore pipe relining actually increases the flow whilst decreasing the likelihood of future blockages. Provides a stronger, more robust interior system, but a more efficient one.

Frequently Asked Pipe Relining Questions

Relining pipes is often more cost-effective and less disruptive than traditional pipe replacement. It avoids extensive excavation, which can affect floors, landscaping, driveways, and more.

Yes, relined pipes can be as reliable as new pipes. Relining materials do not corrode, are seamless, and are resistant to water deposits. They are tested and rated for a long life expectancy, often around 50 years.

The costs can vary depending on several factors, including the amount and type of pipe material, and the layout and design of the piping system. However, relining is typically less expensive than traditional pipe replacement methods.

Various materials, including clay, cast iron, PVC, concrete and steel can be relined.

Even if pipes are in bad shape, pipe relining can often restore them. A technician will need to inspect the site to assess the condition of the pipes.

Considering the cost and time associated with traditional excavation methods, pipe relining is indeed cost-effective. It minimizes downtime and the associated costs of not having functional plumbing.

Pipe relining is applicable for residential, commercial, industrial, historical buildings, hospitals, and condominiums. It can be used for lateral sewer lines, drain lines, branch lines, storm drains, vertical stacks, and electrical conduits.
