A reverse osmosis system removes salts, minerals and other impurities from your water supply by pushing water through fine membranes. When the system is set up properly, the water tastes cleaner and is better for appliances that are sensitive to scale. We install new RO units, replace worn parts and keep your system running the way it should. All work is completed to current BCP plumbing requirements.

Reverse osmosis is one of the most effective ways to clean water. It reduces sediment, minerals and other unwanted particles. Many people choose it when they want better drinking water or when their appliances keep building up scale.
If you are unsure whether an RO system suits your home, we can look at your water supply and explain what difference it will make.
A reverse osmosis system has several filters, a membrane, tubing and fittings that all need to be installed correctly. We mount the unit neatly, connect it to the water line and check the pressure so the membrane can work properly.
If your system is already installed but not performing well, we can replace the filters, check the membrane, look for worn parts and flush the system to get it working again.
RO systems need regular filter changes to keep the water quality high. If filters are left too long, the system works harder than it should and the membrane can wear out faster.
We can set up a simple maintenance routine, check the pressure, look for leaks and make sure the water flow is steady. If you have had your system for a while, we can test the output water and let you know whether the membrane is still in good condition.
If you want an RO system installed or your current setup is not performing like it used to, give us a call on 03 9498 0458 or email info@heritageplumbinggroup.com.au. We can take a look and get it running properly.
