Reasons and Fixes for PVC Pipe Leaks
PVC or polyvinyl chloride pipes are a popular choice for many residential plumbing uses, including drain traps, vent pipes, and the main supply line. They are cost-effective, durable, flexible, and lightweight. PVC pipes are also easy to use, can handle water pressure, and have a long service life due to their rust and corrosion-free properties. They are welded to the fittings using solvent cement that melts the plastic surfaces and binds them.
Despite all the benefits they offer, PVC pipes are not infallible. Eventually, they break or develop leaks. Most PVC pipe problems have quick and easy fixes that a homeowner can accomplish without a professional plumber. However, replacement is the only option if the pipes have suffered extensive damage.
Before getting into the ways to fix a leaking PVC pipe, let’s first understand why a PVC pipe develops leaks.
Reasons for PVC pipe leaks
Here are some of the common causes for a PVC pipe leak:
Installation issues
PVC pipe leaks along the joints and seams are a result of improper installation. Loose-fitting, also known as short insertion, is the most common cause of pipe leaks. The resultant gaps accumulate contaminants, leading to pipe failure.
Exposure to excessive sunlight
If unprotected PVC pipes run above the ground, prolonged exposure to the sun makes them brittle. Either paint them or get a protective covering to prevent damage.
Use of wrong glue
During installations, ensure that the glue used is meant for PVC. Using the wrong adhesive or not applying it in the right quantity causes issues.
Extreme cold
There is a possibility of PVC pipes getting damaged or weak due to chilly winter temperatures. Insulation is an effective solution to prevent freezing pipes.
Underground soils and debris
Friction from rocks and debris under the soil can damage the PVC pipes.
How to fix a leaking PVC pipe
Here are some ways to repair a PVC pipe leak without calling a plumber:
Rubber or silicone pipe repair tape
Repair tape is self-fusing, sticky, stretchy, and gummy. It is one of the most optimal solutions to fix small leaks. For application, stretch and wrap it around the damaged area. The tape completely seals the leak area by forming a long-lasting bond. To cover multiple leak spots on a single pipe, wrap it spirally to cover the whole surface.
Epoxy putty
Repair epoxy consists of resin and hardener. These components, when mixed, plug holes to offer a watertight seal after setting in. They are also available in liquid form and are ideal for repairs in tight spaces where using wrapping tape is impractical.
Dry the affected area and follow the manufacturer’s directions to apply the epoxy. It takes 10 minutes to set in hard. Run water to check if it worked to fix the leak.
Fiberglass cloth
Fiberglass wrap uses a water-activated resin, which, when wrapped around the leak, hardens after 10-15 minutes and stops the leakage.
Rubber tape and hose clamps
To temporarily fix small leaks, wrap the rubber around the leaking area and compress it by tightening two hose clamps at both ends. Use this method on a smooth pipe surface. It won’t work on contours or edges.
A professional plumber can replace extensively damaged pipes. They can also suggest proactive steps to reduce PVC pipe leaks.
