Maintaining your solar hot water system or heat pump in Perth

6 Monthly DIY Check

Perform these simple checks on the Safety Valves every 6 months.

We recommend doing this in a morning during the week (business day).

This will cover us if there are any issues we can assist with over the phone. Worst case scenario & if needed, we still potentially get someone round to assist on the same day.

If these Safety Valves are not letting water through, leak or do not close properly, then they should be replaced. We provide this service!

Tank on Ground

1. Check around the system for leaks, any concerns please email us a picture.

2. There are two relief valves, one at the top of the tank, one at the bottom. Both need checking, one at a time. To do this pull the lever horizontal. Hold open for 5 seconds so water gushes out to clear the mechanism. Be careful to not stand near the splashing of potentially hot water! Once purged return the lever on the valve back to the vertical position. The water should slowly stop coming out of the relief line.

If the safety relief valve does not release any water, leaks, or does not close, then please email us to arrange a service call.

NOTE: the relief valve at the bottom of the tank is the expansion control valve and is meant to drip a little water when the system is being heated.

Water Relief Valves

Tank on Roof

1. The isolation and cold relief valve are typically in-line and installed on an outside wall. Check this relief valve by pulling the lever in-line with the valve. Hold open for 5 seconds so water gushes out to clear the mechanism. Be careful to not stand near where the water will spray out! Once purged, return the lever on the valve back to original position. The water should slowly stop coming out of the relief line.

NOTE: this relief valve call an expansion control valve is meant to drip a little water when the system is being heated.

Check your Solar Valves

2. If you feel competent getting on your roof, then check over your system and test the hot relief valve. Follow the same process of lifting the lever (shown in photo below). However the water should exit at ground level. If you touch your hand on the relief pipe you should feel it rapidly get hot if the mechanism is working as you lift the lever.

Anode Change – Essential Periodic Maintenance

All glass lined or vitreous enamel tanks have an anode.

The anode is a thick rod that sits down the length of the tank and sacrifices itself over time to prevent corrosion.

Just like oil in a car, this anode will need changing periodically (3-7 years depending on system/use).

Our service teams can arrange this to protect the life of your system.
