Automated Mains Water Backup System

Are you looking to install a mains water backup system into your plumbing network? As one of the best ways to switch between using rainwater and your water mains around your property, having a mains water backup system will ensure you are able to fully utilise the current supply of rainwater in your tanks. Not only will this type of system enable an easy and smooth transition between your rainwater and water main use, but it can also save you time, effort and money on your water bills.

How Does the Mains Water Backup System Work?

In essence, a mains water backup system activates when the rainwater level in your tank is too low to provide adequate water pressure. When the system detects this, it will either automatically switch over to using mains water or shut the system off, alerting you that you need to flip the switch.

This prevents damage to your pump, plumbing and appliances and ensures a seamless water supply. Both businesses and homes alike can benefit from a mains water backup system.

Automatic or Manual Switches?


Both automatic and manual switches have their pros and cons. Automatic requires less work on your part, but the initial cost outlay can be higher. Manual switches are often less expensive, but you will need to switch the source. If you later decide to switch from manual to automatic, we can help.

Installation is a Breeze!

A mains water backup system is generally simple to install; much like pumps, it simply attaches to the water outlet and is then plumbed into existing plumbing.

PTJ Green Plumbing will install, test and retest the system to ensure it is working optimally. If you experience any future issues, we offer repairs and replacement too.
