What a hot water service includes
- Testing the pressure and temperature relief valve, and replacing it if it's worn.
- Inspecting the sacrificial anode and replacing it if it's mostly used up.
- Checking the tempering valve delivers no more than 50°C to bathrooms.
- Checking the thermostat, element or burner, and the system's safety devices.
- Checking for leaks, corrosion and drainage from the relief and overflow lines.
- Flushing sediment where the system allows it, especially on tank water.
Hot water system inspection
Buying a house, managing a rental or just unsure about an older system? A hot water inspection tells you its condition, age, likely remaining life and anything that needs attention, with a fixed price for any work.
Hot water valve replacement
We replace relief valves, tempering valves, expansion control valves, non-return valves, isolation valves and pressure limiting valves. A worn valve is one of the most common causes of a system leaking from the overflow.
How often should a hot water system be serviced?
Many manufacturers recommend easing the relief valve every six months and a full service around every five years, but requirements vary by model, so check your owner's manual. On rainwater or bore supply, we suggest checking the anode every two to three years.
Common questions
How often should a hot water system be serviced?
Many manufacturers recommend a full service around every five years and easing the relief valve every six months, but check your owner's manual, as requirements vary by model. Homes on tank water benefit from more frequent anode checks.
Does servicing extend the life of a hot water system?
Yes. Replacing a worn anode and relief valve before they fail protects the tank itself, which is the part that can't be repaired.
