Backflow Prevention Services in Rockhampton

Protecting Your Pipes

Put simply, backflow is the contaminated water that is typically dispensed through the drains at your property. If there is a damaged component within your drains, this contaminated water may ‘flow back’ into your property.
This can pose significant health risks, not to mention undermine the integrity of your plumbing. At Craig Hill Plumbing, we offer a range of services to prevent backflow from entering your property. In addition to repairing your pipes where applicable, we can install specialised prevention devices to help safeguard your property from backflows.
You can count on us to deploy cutting-edge devices to pinpoint affected pipes and get them fixed fast.

Our team can also install thermostatic mixing valves (TMVs). These devices regulate the delivery temperature of water directed from hot water systems. They are essential for keeping the water temperature at your premises at a safe level. To organise a backflow prevention service with our expert team, or request a quote, call us today. In addition to Rockhampton, we service Yeppoon, Gracemere, and The Caves.

What Causes Backflow?

A number of issues can cause backflows to take place in plumbing systems. These include:

  1. A malfunction in the main water supply, which results in low water pressure
  2. High pressure in internal systems, resulting in the reversal of flow
  3. An increased volume of water being pumped from the mains – as might take place in the event of an emergency.

If you notice backflow at your property, call us ASAP. We will promptly diagnose the root cause and implement the most efficient method to get it fixed.

Frequently Asked Questions


Why is backflow a problem?

Primarily, backflow is dangerous as it consists of contaminated water – which can put your health directly at risk. However, backflow can also increase the corrosion levels in pipes, create leaks, and undermine the integrity of your plumbing system.

When do I need backflow testing?

It is strongly recommended that backflow testing be conducted by a professional after a fixture is repaired or installed. At commercial premises – such as shops, restaurants, car washing facilities, etc. – backflow testing is mandatory.

What is the best backflow prevention method?

In most cases, the most effective method is the use of an air gap. This is used to remove the cross connection, preventing backflow in the process. Mechanical backflow prevention systems can be fitted where adding an air gap is not possible.
