Our engineers are experienced in working in a wide variety of different buildings in various public and private sectors, including: offices, leisure, education, health care and social facilities.

Whilst a Legionella Risk Assessment and Management Program is important to reduce the risk of Legionnaires’ disease, it may also be necessary to carry out remedial works on the water system to reduce the risk further.

Pipework modifications / dead-leg piping

Pipework that is rarely used or left unused without a regular flow of water running through them can lead to stagnant water sitting in the pipework which in turn lead to contamination with waterborne bacteria such as Legionella.


Lengths of dead-leg piping measuring approximately 1.5 times its own width should be removed to avoid any potential serious risk to health.


Our engineers are experienced in carry out dead-leg removal and pipework alterations are part of our legionella remedial services.
