Water efficiency tests

Are you a landlord or Strata Manager?

With an investment property, it is important that you understand your rights and responsibilities, especially when it comes to compliance. The water efficiency test guideline is a mandatory requirement for new tenancies. The guideline requires that all fixtures in the rental property are regulated by the water efficiency standard and are efficient in their use of water.


Whether you’re buying your first investment property, or need to maintain an existing property, we can help keep your plumbing infrastructure compliant. At DC Advance Plumbing, we have a team of expert plumbers who understand just how important is it to adhere to these new regulations.

We are here for all your real estate, strata and property maintenance plumbing needs.
