Disinfecting Plumbing Lines

Written by Rebekah Hildebrand

Ultraviolet light works by sterilizing the micro-organisms that pass through the disinfection chamber. The UV rays must interact with the micro-organisms to effectively purify the water. Pre-existing bacteria, viruses, and mold spores in plumbing lines may continue to reproduce down the line. Therefore, it is recommended that the pipes be disinfected to insure that all micro-organisms have been eradicated. If this process is skipped after the installation of a new UV treatment system, a failed water test may result.

Steps

This procedure should be completed during the initial installation process for peak performance.

  1. Pour half a cup of bleach into the plumbing lines after any filtration systems. Bleach is applied after the filters since they will remove the chlorine before it can spread throughout the plumbing lines. For ease of application, it may be possible to remove the filter cartridge and pour the bleach directly into to empty filter. Remember to replace the filter afterwards.

  2. Run all pipes until the chlorine can be smelled. Don’t forget to flush toilets and run all lines including outside spigots.

  3. Let the chlorine process in the pipes for about two hours.

  4. Open all lines until the chlorine smell dissipates. Again, don’t forget about outside spigots.

For Success

This process will flush all plumbing lines of undesirable micro-organisms. The initial sanitation process ensures that the plumbing lines are primed for the UV system to successfully destroy any new micro-organisms. The process may need to be repeated if the system is shut down due to loss of power or any other suspension of operation. If the system is used in a seasonal home and the water is shut off during winterization, the system may need to be shocked again before resuming function.
