Repair or replace?
Not every system needs replacing. Elements, thermostats, pressure relief valves and tempering valves can often be repaired at a fraction of the cost of a new unit. But once a storage cylinder is leaking, replacement is usually the only practical option. We’ll always give you the honest answer on-site, for free.

Hot water questions from Undercliffe
Clear answers to common hot water questions from Sydney homeowners.
What is a pressure limiting valve (PLV), and when is one required?
A PLV reduces excessive incoming mains pressure to a level suitable for the heater and its valves. It is required when supply pressure can exceed the appliance or installation limits and can reduce nuisance discharge and premature component failure.
Are heat pump hot water systems noisy?
They make fan and compressor noise, broadly comparable to a small air conditioner. Quality models are often around 40 to 50 dB, but placement near bedrooms, neighbours or enclosed courtyards still needs consideration.
Should I turn off the electricity or gas before the plumber arrives?
For an electric system that is leaking heavily, switch off the hot water circuit at the switchboard. For a gas leak or suspected gas fault, turn off the appliance gas isolation valve if it is safe to do so and avoid flames or electrical switches. Tell the booking staff exactly what you can see or smell.
Why is my hot water pressure lower than my cold water pressure?
Some difference is normal because hot water passes through the heater, valves and often a tempering valve. A large difference may be caused by a blocked strainer, failing valve, scale, undersized pipework or a restricted heater connection.
Why do I keep running out of hot water?
The tank may be undersized, a heating element or booster may have failed, usage may have increased, or a leaking hot tap may be draining stored heat. High-flow shower heads can empty a small tank very quickly. The first step is checking recovery, household demand and water flow rates.
