How To Fix A Hole In PVC Pipe?

Repairing a hole in a PVC pipe can be a doable undertaking with the correct equipment and techniques. Whether it’s a small pinhole leak or a significant rupture, treating it as soon as possible is critical to preventing water damage and ensuring the proper operation of your plumbing system. 

In this article, we’ll walk you through step-by-step directions on efficiently repairing a hole in a PVC pipe, with options for varied hole sizes and locations.

How To Fix A Hole In PVC Pipe?

PVC is most widely utilized as drain piping because of its ease of use and low cost. Most PVC defects can be repaired to the existing pipe to keep the leakage under control. Here are some details on how to repair or replace your PVC pipes to help you manage the repair or replacement process.

1. Resin Fiberglass Tape

Fiberglass resin tape is used for interim repairs meant to halt damage. It uses water-activated glue that hardens after being applied to the pipe to slow the leaking. This strategy is appropriate for small, non-urgent leaks or leaks that require expert care but cannot be treated quickly. 

What Are The Steps?

  • Gather your materials and make sure that the drainage pipe is empty.
  • Clean the pipe’s leaking location and lightly sand it with the provided sandpaper or 220-grit sandpaper purchased separately.
  • Soak the cloth in water for the time specified by the manufacturer, usually approximately ten seconds.
  • Wring out the cloth and wrap it around the pipe’s damaged section.
  • Seal the pipe with fiberglass resin tape and let it sit for 15 minutes before allowing water to flow through it again.

2. Repair Using Epoxy 

Epoxy is a putty-like or viscous liquid that can be used to repair PVC pipe leaks and joints. To repair a pipe or joint with epoxy, clean and dry the damaged area, ensuring no water can get in.

What Are The Steps?

  • This epoxy works better on a dry pipe, so ensure the drain pipe is empty and the outside is dry.
  • Lightly sand and thoroughly clean the leaky PVC pipe part.
  • Follow the manufacturer’s instructions for mixing the two-part epoxy. We recommend making more than you’ll need to ensure you have enough.
  • Mold the epoxy around the damaged pipe or junction, being careful not to leave any gaps.
  • Allow the epoxy to dry according to the manufacturer’s instructions, usually about 25 minutes.

3. Repair Tape Made Of Rubber And Silicone

Another simple approach to fix small holes in your existing pipe is to use rubber/silicone repair tape. By ‘bonding’ to itself, it can help seal the fissures.

Rubber and silicone tape can also withstand pressures of up to 30 bar. This material helps seal pipe leaks when the water supply cannot be turned off. One of the advantages of this procedure is that no special tools are required.

What Are The Steps?

  • It is advised to sand and clean the leaking PVC pipe lightly. You don’t have to worry about emptying the pipe because this tape may be applied even when wet.
  • Wrap a layer of flex tape around the leaky spot. Press and hold the video firmly against the pipe to make a good seal.
  • Allow the tape to cure according to the instructions. Because this tape typically becomes more robust over time, we recommend waiting 24 hours before reusing the fixture.

4. Slip Coupling Made Of PVC

Because using a slip coupling requires cutting and gluing your PVC pipe, some homeowners may avoid this repair. Furthermore, leaks in lines that are difficult to access may be difficult to repair with this method. However, because it is a permanent remedy, it is advised for long-term peace of mind, especially for leak repairs on underground sprinkler lines, to avoid dealing with another repair down the road.

What Are The Steps?

  • To begin, ensure that the pipe is empty. You’ll need to cut into the line, so keep a towel nearby.
  • Locate the leak and use your hacksaw to cut through the pipe directly on the leak.
  • Sand both sides of the pipe and the inside of both sides of the slip coupling lightly. Before continuing, carefully clean both surfaces.
  • Apply a two-part PVC solvent cement to one side of the pipe and the interior of one side of the connection. Because the cement cures quickly, you must act swiftly.
  • Pull one side of the cut pipe to the side, then twist and firmly press the coupling onto the line. Hold for approximately 15 seconds.
  • Steps 4 and 5 should be repeated with the other side of the pipe and coupler.

5. Replacement

If a PVC pipe is beyond repair, replacing it with a new section of pipe may be necessary. Fortunately, PVC pipe is inexpensive and widely available at most hardware stores.

What Are The Steps?

  • Cut the pipe about one inch to the left and right of the damaged region using a ratchet cutter or hacksaw.
  • Allow extra water to drain from the pipe before drying with a clean cloth.
  • After removing the damaged pipe, dry-fit the replacement pipe into the hole so the pipe’s fitting is correctly fastened around the old PVC.
  • PVC priming solvent should be applied to the interior of the replacement pipe’s fittings and the outside of the current line.
  • Then, apply adhesive to the exposed PVC pipe and the inside of the replacement fitting.
  • Insert the existing pipe into the replacement fittings, twisting it to secure it with adhesive.
  • To establish a suitable attachment, hold the pipe firmly for 10 seconds.

What Are The Most Common Causes Of PVC Leaks?

The following are some of the most typical reasons for PVC pipe repairs and replacements:

1. Incorrect Installation

A leak can develop if a PVC fitting is improperly placed onto the joining pipe. This is frequently the result of a loose fitting that allows water to soak through.

2. Incorrect Sticky Glue

Make sure that you purchase the proper PVC cement to avoid premature deterioration. Before choosing a glue, examine the label to ensure it is intended to stick to PVC. Even if you use the proper sealant, it will ultimately decay and require repair.

3. Temperatures That Are Below Freezing

Although PVC is resistant to freezing, it can become brittle and broken in freezing weather. If you reside in a cold climate, insulate your pipes to prevent them from freezing.

To ensure a thorough repair, repairing a hole in a PVC pipe takes careful attention and the necessary tools. The area around the hole must be carefully cleaned and dried before applying the chosen procedure, whether it’s a repair epoxy, a PVC patch, or a coupling or splice. Following step-by-step instructions and taking appropriate safety precautions are critical for a successful repair that maintains the integrity of the PVC pipe and prevents subsequent leaks.
