Hot Water Repairs Springvale

Hot water in a busy Springvale home

Hot water is the biggest single energy user in most homes, and in Springvale it works hard. Large families, extended families and shared houses all draw on the same system morning and night. Showers, washing, dishes and cooking add up, and a unit that was sized for a smaller household years ago can struggle. Many of the hot water problems we see are actually a system that is simply too small for the people using it.

Common hot water faults

No hot water at all

On a gas storage unit, the pilot light may have gone out because of wind, a faulty thermocouple or a dirty pilot assembly. On an electric unit, the circuit breaker may have tripped, the element may have failed or the thermostat may have stopped switching. On continuous-flow units, error codes often point to an ignition, gas supply or flow sensor problem.

Not enough hot water

Running out faster than usual can mean a failed element on a two-element electric unit, a thermostat set too low, a faulty tempering valve, a broken dip tube in the tank, or a heavy build-up of sediment taking up space. Sometimes it means the household has grown and the unit has not.

Water too hot or too cold at the tap

A tempering valve blends hot and cold water so bathroom taps deliver water at a safe temperature. When it fails, showers can run lukewarm or swing hot and cold. We test and replace tempering valves, which usually need replacing every five years or so.

Leaking water

A small drip from the relief valve drain is normal while the unit heats. A steady stream, water pooling around the base or rust stains running down the side are not. Leaks from the tank itself usually mean it has corroded through and needs replacing. Leaks from valves and fittings can usually be repaired.

Noises

Rumbling or popping from a storage tank often means sediment on the bottom. Hammering when taps close points to pressure problems, which a pressure limiting valve can fix.

Discoloured or smelly water

Rusty water from the hot tap can mean the tank lining is failing or the sacrificial anode is used up. A rotten egg smell can be a reaction between the anode and the water.

What we check

We look at the whole system, not just the part that seems faulty: the gas supply or electrical supply, the burner or element, the thermostat, the relief valve, the tempering valve, the expansion valve on mains pressure units, the anode where accessible, and the age and condition of the tank. Then we tell you plainly whether it is worth repairing.

Repair or replace?

Most storage hot water units last somewhere between eight and fifteen years. If yours is near the end of that range and the tank is leaking, replacement is the only real option. If it is younger and the fault is a part such as a thermocouple, element, thermostat or valve, a repair usually makes sense. We will not push a new system when a repair will do the job.

Gas storage systems

The classic Springvale setup is a gas storage unit outside the laundry or bathroom, often installed when gas reached the street. We relight pilots, replace thermocouples, gas controls and burners, clean flues, replace relief valves and check gas pressure. If the flue or clearances do not meet current rules, we tell you.

Continuous-flow systems

Instantaneous gas units heat water only when you turn on a tap. They save space and never run out, which suits large households, but they rely on a good gas supply and correct pipe sizing. We fix ignition faults, flow sensors, fans and heat exchangers, and test gas pressure with several appliances running.

Electric storage systems

Electric units in Springvale are often in townhouses and units, sometimes in a cupboard, sometimes in the roof space. We replace elements and thermostats, relief valves and tempering valves, and check the wiring connections at the unit. For an electrical fault beyond the unit, you will need an electrician.

Heat pumps

Heat pumps work like a fridge in reverse, pulling heat from the air into the water. They are efficient, especially with solar panels, but need correct installation and clear airflow. We service and repair heat pump systems and check fans, compressors, sensors and backup elements.

Hot water and safety

Hot water must be stored at 60 degrees or more to control Legionella bacteria, and delivered to bathrooms at no more than 50 degrees in most homes to prevent scalds. A working tempering valve does that job. We check and set these temperatures on every hot water visit.

For renters

No hot water is an urgent repair under Victorian rental law. Tell your agent or landlord straight away. We can work directly with agents and provide invoices and reports.

Looking after your system

• Ask us to check the relief valve and tempering valve every few years.
• Have the anode inspected on storage tanks to extend tank life.
• Keep the area around the unit clear of rubbish, plants and stored items.
• On heat pumps, keep leaves and clutter away from the fan.
• Fix small drips before they become big leaks.

Shops and restaurants

Food businesses need reliable hot water for dishwashing, hand basins and cleaning. We repair and replace commercial units, including multiple continuous-flow units manifolded together, and can schedule work outside trading hours.

Tempering valves and scald safety

Many Springvale homes have older family members and young children under the same roof. Both are at higher risk of scalds. Since 1998, new hot water installations in Victoria must deliver water to bathrooms at no more than 50 degrees, usually through a tempering valve. These valves wear over time. If your shower temperature wanders, or water is very hot at the basin, ask us to test it. Replacing a tempering valve is a quick job that makes a big difference to safety.

Relief valves

Every storage hot water unit has a temperature and pressure relief valve near the top of the tank. It lets out water if the pressure or temperature gets too high. A few drips while heating is normal. Constant flow means the valve is worn or the water pressure is too high. Lift the valve's lever gently every six months to stop it seizing, and have it replaced about every five years.

Hot water in units and townhouses

Hot water systems in units are often in tight cupboards, on balconies or in roof spaces with limited access. A leaking roof-space unit can bring down a ceiling, so it should sit in a safe tray with a drain. We check access, trays and flues when we repair these systems and point out anything that does not meet current rules.

Repairs we carry parts for

Our vans carry thermocouples, pilot assemblies, common elements and thermostats, relief and tempering valves, and parts for popular continuous-flow units. That means most repairs are finished on the first visit, without you waiting days for a part.

Continuous-flow error codes

Continuous-flow units show an error code on the controller or the unit itself when something goes wrong. Common codes point to ignition failure, low gas pressure, overheating, a blocked water filter or a flow sensor fault. Write down the code and the brand when you ring, and we can usually tell you what is likely and bring the right part. Some faults are as simple as a dirty inlet filter; others are a failed fan, igniter or heat exchanger.

Sediment and water quality

Melbourne's water is relatively soft, but storage tanks still collect sediment over the years, especially after works on the mains stir up the pipes. Sediment shortens the life of elements, makes noises and reduces capacity. Draining and flushing the tank during a service helps. The sacrificial anode inside the tank corrodes instead of the tank itself, so replacing it before it is used up can add years to a unit's life.

When to call straight away

Call us immediately if the unit is leaking steadily, if you smell gas near it, if the relief valve is pouring water, or if the water from the hot tap is scalding. Turn off the gas or power to the unit first.

Electric units and off-peak power

Electric storage units on an off-peak tariff heat overnight. If you run out in the evening, the unit may be on a timer that does not boost during the day, or one element may have failed. We test both elements and thermostats and check the unit's wiring connections.

If your unit is more than ten years old and you are planning a renovation or solar install, ask us about the replacement options at the same time, so the new system suits the house you are building towards.

Springvale ground and pipes

Springvale sits on a mix of sandy loam and heavier clay, and much of the suburb was built in the 1950s and 1960s with earthenware sewer pipes and galvanised or early copper water pipe. Clay joints shift over time and let roots in, rusting galvanised pipe slowly narrows and leaks, and drains under subdivided blocks are often shared between homes. We use drain cameras, locators and pressure tests to see exactly what is going on before anyone digs.
