Step 1 – Flushing

When you installed the system, most likely some dirt and other debris entered the pipework. You need to expel this before using the system.

Flushing must occur in the following order:

  1.  each end of the mainline individually
  2.  each end of the submain individually
  3.  the laterals in 25% of the block at a time, according to the required velocity (see Module 4).
