If your unit(s) is equipped with any of the following:

  • Holding tanks with or without pumps
  • Hot water tanks
  • Washrooms with porcelain fixtures
  • Surface mounted plumbing and in-wall/in-floor plumbing and fixtures

And you plan on disconnecting the power or leaving units unheated.

This typically applies to portable washroom units and buildings with kitchens.

A shut-down applies to any period of time where power will be disconnected, or heat will be shut off, even if it's just a few days.

When disconnecting the power or leaving units unheated, winterization is necessary to prevent frozen pipes and water damage. 

If units are left unheated and are not properly winterized, waterlines will freeze. When defrosted, leaks, plumbing damage, and water damage are very likely, and in most cases, very costly.
