Pros of Epoxy Pipe Coating: Benefits, Process & When to Use It

An Introduction to Epoxy Pipe Coating

Water damage is one of the most common and expensive problems a home or business owner can face. Leaky pipes, burst pipes, water heater supply line failures, appliance leaks, and flood damage can all lead to costly repairs.

According to the Insurance Information Institute’s 2023 data, water damage claims account for 24% of all home insurance claims, with the average claim payout reaching $12,514.

If your home or business needs pipe repair, but you want to avoid the cost, mess, and disruption of traditional repiping, epoxy pipe coating may be worth considering.

Also known as epoxy pipe lining, this method restores existing pipes from the inside. In this article, we’ll explain when epoxy pipe coating may be needed, how the process works, and the key benefits property owners should understand before choosing a pipe repair solution.

What Is Epoxy Pipe Coating?

Epoxy pipe coating is an in-place pipe restoration method that applies a protective epoxy barrier to the inside of existing pipes.

Instead of tearing out walls, floors, ceilings, or concrete slabs to replace damaged plumbing, the existing pipe is cleaned, prepared, and coated internally. Once cured, the epoxy creates a new protective lining inside the old pipe, helping seal pinhole leaks and reduce future corrosion-related problems.

This approach can be used as an alternative to traditional pipe replacement when the existing piping system is a good candidate for restoration.

You Might Need Epoxy Pipe Coating If…

Older homes and commercial buildings often have plumbing systems that have degraded over time. Without inspection or preventative maintenance, aging pipes can develop leaks, corrosion, low water pressure, or water quality concerns.

Here are common signs your property may need epoxy pipe coating or another pipe repair solution.

High Water Bills

A steady, unexplained increase in your water bill may indicate a hidden leak. Even a small pinhole leak can waste water and cause serious damage if left untreated.

Odor or Mold

Leaking pipes can lead to moisture buildup, mold, and mildew. If your home or building suddenly has a musty odor that cannot be explained, the plumbing system may be the source.

Puddles in the Lawn

Water pooling in your yard may point to an underground pipe leak or slab leak. If ignored, this can lead to expensive and time-consuming repairs.

Sound of Dripping Water

If you hear water dripping when no faucets, showers, or appliances are running, there may be a leak somewhere in the plumbing system.

Low Water Pressure

A sudden drop in water pressure can signal a plumbing problem. If your sinks, showers, or fixtures are running slower than usual and no pressure adjustments were made, a leak or pipe issue may be present.

How Does Epoxy Pipe Coating Work?

Epoxy coating works by creating a new, functional lining inside the existing pipe. The coating seals small leaks, pinholes, and corrosion-related cracks while helping protect the pipe from further internal deterioration.

The epoxy pipe coating process generally includes three key stages: evaluation, preparation, and placement.

Step 1: Pipe Evaluation

The first step is to evaluate the existing piping system to determine whether epoxy coating is the right solution.

A professional inspection may include camera evaluation to identify the condition of the pipes, locate problem areas, and confirm whether the system can properly accept an epoxy coating.

In some cases, if the pipes are too damaged, traditional replacement or repiping may still be necessary.

Step 2: Pipe Preparation

Once epoxy coating is determined to be appropriate, the pipes must be prepared.

Before the coating is applied, the pipe sections are typically isolated, drained, dried, and cleaned. With ePIPE, the inside of the pipe is prepared using a patented burst sanding method, which is designed to clean the interior pipe wall so the epoxy coating can properly bond.

Proper preparation is critical because adhesion affects the performance and longevity of the finished lining.

Step 3: Epoxy Placement and Curing

After preparation is complete, the epoxy coating is applied by moving a predetermined amount of resin through the pipe section.

The specialized two-part epoxy resin cures in place, forming a protective barrier coating between the old pipe and the water flowing through it. This process is completed while the pipe remains “in-place”, without ripping into floors, walls, or ceilings.

That means homeowners and property owners can restore flow through their existing piping system without the mess, hassle, and long timelines often associated with a full repipe.

Pros of Epoxy Pipe Coating

Now that you understand how epoxy pipe coating works, here are the main benefits to consider.

Cost-Effective Alternative to Repiping

Compared to traditional pipe replacement, ePIPE can cost up to 50% less when all costs are considered.

Because pipes are restored in place, property owners may avoid the added expenses of demolition, reconstruction, drywall repair, flooring replacement, and extended downtime.

Less Disruption and No Major Displacement

Traditional repiping can be invasive, especially when pipes are located behind walls, above ceilings, under floors, or beneath a slab.

Epoxy pipe coating is designed to reduce disruption. In many cases, property owners or occupants do not need to vacate the building. Water service can often be restored the same day, and depending on the scope of work, it may be restored in just a few hours.

ePIPE has one of the fastest approved turnaround times in the industry it serves.

Durable Pipe Protection

Epoxy pipe coating creates a pipe-within-a-pipe system that helps seal leaks and prevent new ones from forming.

The protective barrier coating is designed to stand the test of time and provide a long-lasting solution for eligible piping systems.

Supports Lead and Copper Reduction

Properties built before 1986 may have plumbing systems with lead contributors, including lead pipes, leaded solder used on copper pipes, or brass fixtures with higher lead content.

ePIPE’s patented lead and copper reduction process is designed to help reduce heavy metals such as lead and copper from leaching into drinking water. The system can bring lead and copper leaching to well below EPA and World Health Organization cutoff levels.

Eco-Friendly and Safe for Potable Water Systems

Epoxy pipe coating can help reduce the need to demolish and discard existing pipe materials.

ePIPE and its LeadSmart program are designed to focus on protecting potable water systems and reducing concerns related to lead and copper leaching.

Potential Increase in Property Resale Value

A restored plumbing system can be an attractive feature for future buyers.

If you decide to sell your home or building, updated pipe restoration may help support resale value by showing that proactive plumbing improvements have been made.

Are There Downsides to Epoxy Pipe Coating?

Like any pipe repair method, epoxy coating may not be the right choice for every situation. Here are two considerations property owners should understand.

Possible Delamination

Delamination occurs when the epoxy material separates into layers. While this is rare, it can happen if products are not properly engineered, installed, or quality controlled.

ePIPE is engineered for its intended application and is applied using a quality-controlled program.

Slight Reduction in Pipe Diameter

Because the coating cures inside the existing pipe, the interior diameter becomes slightly smaller.

However, ePIPE is an approved plumbing product and process that takes water flow into account. As part of quality control, flow tests are conducted at each fixture before and after the ePIPE process.

Is Epoxy Pipe Coating Right for You?

If you are dealing with frequent leaks, corrosion, low water pressure, or repeated pipe problems, epoxy pipe coating may be a smart alternative to traditional repiping.

For many homeowners, building owners, and property managers, the biggest advantages are reduced disruption, lower overall repair costs, same-day water service restoration in many cases, and long-term protection for existing pipes.
