Back Flow & TMV

Back Flow & TMV

NARELLAN PLUMBING is certified in this area.

As a result can take care of your back flow and TMV (thermal Mixing Valve) installation and testing requirements.


Back flow prevention is a necessity to ensure our potable (drinking) water supply is free from contamination or cross connection.

So it is imperative to have your devices regularly checked and serviced.


Thermostatic Mixing Valves

TMV’s are to ensure that there is no chance of burning injuries from heated water.

While in places where the elderly, disabled or children are exposed to heated water the TMV limits the temperature to around 50 degrees celsius therefore creating a safe temperature to shower, bath in.
