Frequently Asked Questions

What causes my water tap to leak?
Leaking water taps are often caused by defective parts and frequent use. Constant leaks may require a plumber to inspect and diagnose the problem.

In many cases, damaged components such as the jumper valve and O-ring can be replaced with new ones. However, replacing the entire tap may be necessary if the fixture is beyond repair.
Is DIY plumbing illegal?
Yes, in most cases, DIY plumbing is a safety risk and not recommended.

While there are jobs such as changing a shower head that you can perform without expert assistance, having a licensed plumber is necessary.

A licensed plumber can undertake extensive plumbing installations. They also handle repairs and maintenance effectively.
Do you provide gas fitting for commercial properties?
No, we work predominately with new home builds and renovations.
What brands do you source?
We install gas products from leading brands, Thermann, Rinnai and Vinidex.
What are the things to consider when installing a hot water system?
The type and size of the unit, and the area where you want it installed are important factors to consider. Gas and solar hot water systems have varied pricing and running costs.
How often should hot water systems get serviced?
Generally, gas and solar hot water system maintenance is done every 5 years.

Maintenance schedules may vary depending on how frequently the unit is being used.
Why is my septic system flashing lights?
The flashing red light usually signals warning that the wastewater treatment system has functionality issues.

These may mean high water levels that need to be stabilised or any other problem which may lead to complex repairs if left unaddressed.
How often should the system be desludged?
On average, septic tanks have to be desludged once every three years. The frequency of desludging will depend on the number of people using the septic tank.

Always confirm desludging requirements with your local council, as they vary depending on your location.
Why should I buy a rainwater tank?
Having a rainwater tank is a cost-effective, environmentally friendly way of using water. It allows homeowners to use the collected water for irrigation and laundry chores, helping you save money.
Can I use the water for personal consumption?
Water collected from the rainwater tank can be used for drinking. However, proper filtration systems need to be installed.

The type of tank installed must be carefully assessed and approved by the local council for your safety.
