My Pipe Burst - Why?

Updated: May 9, 2022

There are numerous reasons why pipework can fail. It is usual joints that fail or rather the connections between the joints and the pipes. Which is all commonly refereed to as pipework.

The original joint and pipe should be inspected.

The following situations are some potential possible causes of failure of a push fit joint;

● Pipe is not inserted fully into the the socket of the fitting/ insufficient pipe or only the insert has

passed into the socket insufficient to maintain a lock

● Inserts have not been inserted. Pipe end not sufficiently firm for lock/seal to be maintained.

● Pipe end is damaged and therefore was not locked/sealed.

● Fitting has been disassembled and then reassembled incorrectly.

● A collect release triggered was used and not released/stuck by malfunction.

● Twist Screw cap in unlock position.

● Fitting was reused, second hand or a resold returned item.

● Fitting was supplied faulty from factory.

● Fitting was a counterfeit.

● Fitting was damaged in transit or distribution.

● Fitting was damaged on site before installation.

● Fitting/joint damaged by heat works from soldiering on pipework in proximity or hot works by

others in proximity.

● Fitting damaged/joint damaged by mechanical works of site operatives (e.g power tools

hammering or drilling in proximity)

● Fitting/joint damaged by force (e.g. pipe stepped on).

You should contact your insurance provided immediately, and considering carrying out the instructions below.

Take photos. Document any damage. Obtain a job report from whoever makes the repair and an invoice.

The joint/pipe manufacturers instructions should be consulted for appropriate pipe support

instructions. A photo could be sent to manufacturers in order to identify the part.

If applicable to works (under Water Regulation 12) documentation or a “Test Certificate”

regarding appropriate pressure testing should be sought from the installing contractor

regarding pressure testing in line with Water Regulations 1999

Water Regulation 12/“BS EN 806: Part 2 covers design, clause 3.4.2 which covers strength


‘To ensure adequate strength, all components of the system shall be designed to meet the test

pressure requirements of the local and national laws and regulations. The test pressure shall be

at least 1.5 times the allowable maximum operating pressure (PMA).’

If you have any further questions consult a local qualified plumber.
