Hot Water Not Working?
When I try to relight the pilot flame and I release the button the pilot flame goes out
Hot water not working? Quite possibly the thermocouple has failed and needs replacing by a qualified plumber. The thermocouple provides a safety feature for a gas hot water system. When the pilot is not on, the valve will not allow any gas to be delivered. Is the gas on? Ring (08) 8444 7320 for immediate assistance.
I have a gas hot water service and have tried to relight the pilot flame but it will not light at all.
Either the pilot jet valve is blocked or the main gas thermostat has failed or the gas line to the pilot is full of air and requires purging or maybe repair. Ring (08) 8444 7320 for immediate assistance.

Not Enough Hot Water
A clogged flue or vent could be the problem or a defective thermostat. Ring (08) 8444 7320 for immediate assistance if hot water not working.
I have an instant gas continuous flow hot water service and only luke warm water is coming out of my taps
The diaphragm or thermostat has more than likely failed and requires renewing. Ring (08) 8444 7320 for an immediate
Hot water cuts out or goes hot and cold when showering.
The type of shower head installed and the type of hot water system in use may not be compatible. Certain types of hot water systems cannot deliver consistent temperature with water saving shower roses as they need a certain flow rate per minute of hot water to function. This is common with continuous flow gas hot water systems. See here.
It is a good idea to call (08) 8444 7320 and have one of our plumbers visit to check if the shower head is compatible and if not either remove the restrictor or install a high flow shower head to see if this removes the problem if hot water not working.
My hot water is too hot, how do I adjust the temperature?
If your systems is fitted with temperature control try adjusting it. For other units Call (08) 8444 7320 and we’ll send around a hot water plumber if hot water not working. Hot water systems need to be adjusted by a qualified plumber experienced with hot water, to avoid the possibility of burns occurring. There may well be an issue with the thermostat.
I have an electronic ignition continuous flow gas hot water system and the flow is reduced and water is cold .
Problem may be either the thermostat or a blocked strainer valve on the cold water inlet to the hot water unit. Ring (08) 8444 7320 for an immediate response.
I have water leaking from the tank or from the pipes, what do I do?
Turn off the water to the property. This is probably located on the verge at the front of the premises. Then call (08) 8444 7320. This is a job for a qualified plumber if hot water not working.
I have water leaking down through my ceiling, what do I do?
The first thing you need to do is turn off the water. Go to the main water meter for your property as above, and close the tap so no more water flows. Call our emergency hotline on (08) 8444 7320.
Electric Hot Water Not Working?

What preventative action can I take to stop corrosion to my hot
Sacrificial anode protection is the way to arrest hot water cylinder corrosion and this applies only to steel vitreous enamel lined or glass coated mains pressure hot water cylinders. It does not apply to stainless steel systems.When steel cylinders are internally lined under very high heat in the manufacturing process, very small patches in the cylinder fail to be coated so anodes are employed to protect the bare steel from corrosion.
A sacrificial anode is a rod made up of differing compounds depending on specific water conditions. They are immersed into the tank and screwed in from the top of the unit.Cylinder corrosion is directly related to the quality of the mains water which governs the rate an anode sacrifices itself to protect the cylinder. Obviously the anode will need replacing eventually, normally every 3-4 years.
Regular anode replacement will on average add one third more life to a hot
water cylinder but with the cost of replacements you are paying for that
Is a gas hot water system a suitable alternative to solar or heat pump hot water systems?
systems are a viable alternative from a couple of perspectives. The first is reliability, and the second are the low initial purchase price and ongoing maintenance costs.

Are heat pump units or solar units cheaper to run?
Generally, solar hot water units can be up to 5-15% cheaper to run than heat pump units but are not as reliable and are more expensive to install and maintain.
I need a new hot water system installed. Which is better a 5 star rated gas mains pressure storage hot water system or an instant flow continuous gas unit?
It depends. Both systems are 5 star energy rated.
Continuous flow instant gas units take time to detect water running through the system before the gas burner is activated which can result in as much as 20 litres of water wastage. This water wastage is a concern for those looking to reduce their water usage. On the other hand, as the name suggests, continuous flow systems are always available, no more worrying about if there is enough water in the tank for showering, laundry etc.
Mains pressure storage systems deliver hot water at full mains pressure as opposed to the restricted flow of the instant gas units which can cause problems with fluctuating temperatures when showering especially in multi bathroom homes. If someone is showering and another person decides to do the washing up the person in the shower will not be too happy – with a continuous flow system.
On the other hand, new Gas Hot Water Systems from Bosch overcome this issue with temperature control keypads which the person in the shower would use to preset the temperature. That way the whole house receives water at this pre-assigned temperature.
Mains pressure storage tanks also permit water saving shower heads which may not be possible with continuous flow systems which need a certain flow rate
to enable the water to be heated.So a mains pressure system may be better from a water saving perspective but a continuous flow involves no worry as to whether there is enough water in the tank and also saves on gas. It only heats the amount of water required, not a whole tank.
Solar Hot Water Questions
What if the sun doesn’t shine, will my shower and hot water still be hot?
Yes, the solar hot water systems we install have either 5 star gas boosting or 5 star electric boosting for when the sun isn’t shining.
Which is better, Gas boosted or <ahref=”https://sahotwater.com.au/hot-water/kelvinator-solarknight-flat-panel-340″>Electric boosted solar?
Gas boosted is more “set and forget”. Electric boosted requires more manual intervention. If the water is not hot you need to activate the electric boost. Due to this inconvenience many owners choose to leave the boost permanently on, thereby negating any possible savings! Gas boosted is more expensive to install however. This is offset by being the most energy saving type of system in the long term.
How does a boosted solar system save me money?
Yes, up to 90% less energy than older storage type electric water heaters. Less energy consumed= smaller bills.
The solar hot water system is leaking water onto my roof.
Either the solar panel is burst or the pipe connection to the panel has burst. Isolate water at isolating valve or at water meter. Ring (08) 8444 7320 for immediate help.
Heat Pump Hot Water Questions
What if the sun doesn’t shine, will I still have hot water?
Yes, the heat pump hot water systems we install work in any weather conditions, rain, hail or shine. Heat pumps work by drawing heat from the ambient air temperature and do not require direct sunshine unlike solar units. Different technology.
