If you have ever used SharkBite fittings in your plumbing projects, you know how convenient and easy they are to install. They are push-to-connect fittings that save you time and money by eliminating the need for soldering, gluing, or threading. Sometimes you'll discover your SharkBite fitting leaking, though.

They could be better in some cases (or due to user error) and can sometimes leak, and this can cause water damage, mold growth, and high water bills. This article will help you understand why SharkBite fittings leak and how to prevent it.

What Are SharkBite Fittings & How Do They Work?

before delving into sharkbite fitting problems we must first understand what are sharkbite fittings & how do they work?

SharkBite fittings are a quick and easy way to connect different pipes without soldering, gluing, or clamping. They have a brass body with a rubber seal, and a metal ring grips the pipe firmly. You need to cut, deburr, mark the pipe, then push it into the fitting until it clicks.

To remove it, you need a special tool that releases the ring. SharkBite fittings work with most pipes but not with gas lines, fire sprinklers, or pipes in extreme weather. Always follow the instructions and codes before using them.

Common Causes of SharkBite Fitting Leaks

SharkBite fittings are designed to create a leak-proof seal, but they can sometimes leak for various reasons. Some of the common causes of SharkBite fitting leaks are:

Improper Installation:

If the pipe is not inserted fully into the fitting, or if the pipe is not cut straight, deburred, or cleaned properly, the fitting may not seal correctly and may leak over time. A SharkBite leak is usually do to user error like this.

Physical Damage:

If the fitting or the pipe is bent, cracked, scratched, or corroded, the seal may be compromised and may leak. This can happen due to improper handling, storage, or installation of the fitting or the pipe. This has been the cause of many a SharkBite connector leaking.

Paint Interference

If the pipe is painted near the end that goes into the fitting, the dried paint may interfere with the O-ring seal and cause it to leak. This can be avoided by removing any paint from the pipe before inserting it into the fitting.

O-Ring Failure

If the O-ring inside the fitting is damaged or missing, the fitting will not be able to create a watertight seal and will leak. This can happen due to wear and tear, exposure to chemicals or UV rays, or manufacturing defects. These can dry rot and become a main source for a SharkBite fitting leaking.

If you notice a leak in your SharkBite fitting, try to fix it as soon as possible to prevent water damage and waste. Here are some steps you can follow to fix a leaking SharkBite fitting:

1) Turn off the water supply to the leaking fitting and drain any excess water from the pipes. 

2) Identify the source of the leak by inspecting the fitting and the pipe for any signs of damage or paint interference.

3) Remove the pipe from the fitting using a SharkBite disconnect clip or tong to release the gripper ring. You can also use an adjustable wrench and your fingers to push in the cufflink part of the fitting and pull out the pipe.

4) Check both the pipe and the fitting for any damage or debris. If you find any cracks, scratches, corrosion, or paint on either of them, you may need to replace them with new ones.

5) If both the pipe and the fitting are in good condition, you can reinsert them into each other. Ensure you deburr and clean both ends of the pipe before inserting them into the fitting. Use a permanent marker or a SharkBite depth gauge tool to mark the insertion depth on the pipe. Push both ends of the pipe into the fitting until they reach the mark.

6) Turn on the water supply and check for SharkBite leaking again. If the leak persists, you may need to contact a professional plumber for further assistance.
