Why is my sharkbite fitting leaking?

Last Updated: 23rd February, 2020

Keeping this in view, how do you stop a SharkBite from leaking?


  1. Cut the copper pipe gradually.
  2. Outer edge of the copper pipe must be reamed clean – we advise to ream/deburr the inside also to reduce turbulence.
  3. Measure – pipe must be fully inserted into the fitting to a depth specified in instructions.
  4. Use PEX stiffener (insert) when using push fittings with PEX tubing.

Additionally, how does a SharkBite fitting seal? The SharkBite® connection system uses an advanced push-fit design that works in two stages. When the tube is inserted into the fitting it passes the first stage through a release collar and then through a stainless steel grab ring. The grab ring has teeth that open out and grip onto the tube.

Keeping this in consideration, how long do SharkBite fittings last?

25 years

Are SharkBite fittings reliable?

If you need to repair or replace copper plumbing in your home, a SharkBite fitting is an excellent choice. Sharkbites are approved for use underground and behind walls, but installing them there could be risky. A SharkBite fitting contains a rubber O-ring, which is not best for permanent connections.
