What do hot water system installation services include?

Hot water system installation services include all the activities necessary to put a reliable, safe hot water system in your home. This involves installing an unvented hot water system, inspecting the installation area, preparing materials, installing the cylinder or tank, then making the needed connections. After the installation, your plumber can test the system for flaws and address them as needed.

Inspecting installation area

Your water heater installation begins with a thorough inspection of the spot that will house the tank and its components. Your plumber makes sure that the floor is robust enough to support the cylinder's weight and complies with established building codes and safety rules and regulations. If the allotted space is deemed insufficient for the cylinder, your plumber can help you look for an alternative spot for the unvented cylinder service. 

Preparing for installation 

Your plumber makes the necessary preparations for the hot water cylinder installation. If necessary, some plumbers may offer to make an improvised platform of sturdy materials to support the tank's weight. Otherwise, you can hire a Tasker to handle all your carpentry needs.

When appropriate, your hired plumber shuts off the power, gas, and water supply before starting the job. They can take all the necessary measurements to determine the right amount of materials, then cuts and bends wires and pipes to the appropriate lengths and widths. Your plumber may also cut holes into walls or floors as needed to allow pipes or wires to run through.

Installing the cylinder

Once the cylinder's space is ready, your plumber can proceed with the unvented hot water cylinder installation. They can place the cylinder or tank onto its designated space and position. Your plumber takes care not to damage any of the components of the vented hot water cylinder or other pipes and wires in its surroundings.

Installing components and pipes

After the cylinder is in position, your specialist proceeds with attaching the appropriate pipes, wires and components like the Temperature and Pressure Release valve, expansion vessel, immersion heater, and any other pipes and valves. As with all other stages of the unvented cylinder installation, they use appropriate materials and techniques that are compliant with state safety and building regulations and industry best practices. 

Testing the system

Your hired plumber tests the system after completing the installation. They check that each tap and shower head provides hot water on demand and flows with consistent pressure. Should variations in temperature or pressure arise, your plumber can troubleshoot the system and do the appropriate fixes. 

They repeat this process until the hot water system works without any issues. And now that your home has hot water running through your taps, tubs, and showers, why not ensure greater warmth and comfort in every room of your home? On Airtasker, you can also hire an insulation installer who can help you cut down on bills and achieve year-round comfort.

Hot Water System PTR Valve issue – Suspected High Water Pressur

$300

Brighton East VIC 3187, Australia

19th Feb 2026

I have an Aquamax G390SS hot water tank that has recently started to leak a steady stream of water from the pressure relief valve. • When I turn off the cold inlet to the tank, the leak slows right down. • When I turn it back on, the flow increases again. • Cold water pressure in the house feels strong. • The council recently changed our water meter. I’d like you to: 1. Check the mains water pressure at the property 2. Confirm whether I have a pressure limiting valve and whether it’s working correctly 3. Check whether I have an expansion control valve and if it’s functioning 4. Replace the PTR valve if required The system is about 5 years old.

Did a great job! Thanks!
