Signs your hot water system is failing

Several indicators suggest a failing hot water heater requiring immediate attention:

  • Inconsistent water temperature - If you experience fluctuating hot water temperatures or the water alternating between hot and cold, this could signal an issue with the thermostat or heating element.
  • Strange noises - Unusual rumbling, banging or hissing sounds could mean a noisy hot water system, including issues like a faulty pilot light or sediment buildup.
  • Leaking or puddles around the unit - Water leaks around your hot water heater signify a need for repair.
  • Discoloured water - Rusty, cloudy or smelly water points to corrosion inside your hot water heaters and the need for flushing or replacement.
  • Increase in energy bills - A spike in your energy bills can raise concerns, being a common hot water system issue and a sign of a faulty or inefficient system.

Ensuring that a plumber services your hot water tank every 1-2 years is essential for maximizing the system’s lifespan and performance. If you notice any of these warning signs, contact a licenced plumber to inspect and fix the issue before it worsens. Acting on early wear signs with preventative maintenance can prevent breakdowns and expensive repairs later on.

Temporary hot water solutions

If you’re experiencing a lack hot water because your system breaks, there are some temporary solutions you can use while waiting for professional help:

Boil water

Boiling water on the stove is a temporary fix for basic needs, such as handwashing. Exercise caution to avoid burns when handling the hot water.

Electric kettle

An electric kettle can rapidly boil water for uses like sponge baths. Again, take precautions against scalding when pouring.

Portable camp shower

A battery-operated portable shower provides a comfortable bathing alternative during a hot water outage, complete with its own water inlet. Place it in the shower or tub and adjust the temperature as needed.

Gym membership

Without hot water at home, consider using local gyms, which often provide day or week passes for shower access. Their facilities may offer a solution until your hot water supply is restored, providing hot running water.

Visiting family/friends

Staying with family or friends can help you out your situation, providing an alternative source of hot water until your system is up and running again.

While these steps offer short-term solutions, they help maintain cleanliness until your hot water system is repaired. Call your professional plumber as soon as possible to properly inspect and conduct hot water repairs on your system.

Evaluating repair vs replacement

If your system malfunctions and you’re without hot water, deciding whether to repair or replace the unit is critical. Here are some factors to consider when deciding between repair and replacement:

Age of the system

The expected lifespan of hot water systems, from storage tanks to tankless models, is essential and requires proper maintenance. If your system is near or past its expected lifespan, replacement may be the better option.

Frequency of breakdowns

Frequent repairs and breakdowns in electric hot water systems over time could indicate issues with the tank itself, usually a telltale sign of an ageing system. There’s a point where constant repairs are less cost-effective than the benefits of installing a new unit.

Cost of repairs

Evaluate the repair quote from your plumber. In some cases, a new hot water system may be only marginally more expensive than making major repairs.

Energy efficiency

High-quality water heaters are more energy efficient. Replacing an older unit can yield significant long-term savings on your energy bills.

A licensed plumber will effectively evaluate your system’s condition to advise on the best course of action - whether to repair or replace. They can also handle the installation of a new unit if needed.

Estimating repair costs

The cost to repair your hot water system can vary significantly depending on the specific issue and parts required. Some factors that influence repair costs include:

Type of repair

Minor repairs to electric hot water systems, such as fixing a leaking valve or replacing the anode rod, typically cost around $200 to $400. More complex repairs such as pump or thermostat replacement typically range from $400 - $1200.

Plumber call-out fee

Plumbers generally charge a diagnostic call-out fee between $80 and $150, not including labour and parts.

Labour time

Basic repairs such as fixing a leaking tap can take 1-2 hours, whereas more extensive repairs may need over 4 hours. A very professional, licenced plumber may charge $80 - $150 per hour for labour.

Parts

Replacement parts for water heater tanks can range from $50 - $500 or more depending on the specific part. Thermostats, heating elements and pumps tend to be more expensive.

Accessibility issues

Accessible systems avoid higher labour costs, so prepare for potential extra charges if your system is difficult to reach.

Replacing the sacrificial anode rod every five years for $150 - $300 can greatly extend the life of your tank and stave off costly breakdowns.

For a precise assessment and repair quote, it’s advisable to consult with a professional plumber. Many offer free on-site estimates. Understanding potential costs will help you budget for any repairs.

Living comfortably without hot water

Dealing with a broken hot water system, even temporarily, can be quite disruptive and inconvenient. With appropriate planning and adjustments, you can reduce the inconvenience until your hot water system is operational again.

Take Advantage of Public Facilities

When your hot water system breaks, local gyms, community centres, and truck stops often provide showers you can use for a small fee. Some campgrounds also have communal washrooms and showers.

Wash Up Selectively

Prioritise washing hands, face, armpits, and feet with boiled or microwaved water. Use wipes, sponge baths, or spot clean other areas. Wash clothes and sheets at a laundromat if needed.

Use Disposable Dishware

Switch to disposable plates, cups and utensils to reduce dishwashing needs. Stock up on paper towels as well.

Be Cautious With Alternative Heating

When employing space heaters during repair work, safety is paramount; do not leave them unattended near water sources. Consult the owner’s manual. Consider heating water on a grill outdoors.

Insulate Pipes

To prevent pipes from freezing, insulate them with foam sleeves available at hardware stores.

While not ideal, planning proactively can help maintain cleanliness and prevent frozen pipes when relying on cold water. Contact a plumber to restore your water repairs service as soon as possible.

Safety issues with a broken system

A failing hot water system presents several safety hazards that require immediate action. Be aware of the following risks:

Electric shock

Damaged parts, defective wiring, or exposed conductors in gas water systems raise the risk of potentially fatal electric shocks. Avoid getting anywhere near the electrical connections. Shut off power at the main circuit breaker before attempting any DIY repairs.

Gas leaks

Gas water systems can develop hazardous leaks due to damaged supply lines or malfunctioning control valves. If you suspect a leak, turn off gas supply, evacuate the house and contact the gas company or fire department immediately. Do not turn any electrical devices on or off.

Scalding

A faulty thermostat or low water pressure can disrupt heating efficiency, leading to excessively hot water and a scalding hazard. Do your checks on both the hot water tap temperature and pressure before use, particularly for bathing children or the elderly.

Flood risk

Leaking water tanks or areas with cracked fittings and corroded pipes can lead to water damage, necessitating swift action to shut off the water supply and avoid serious leaks and flooding. Cut off the water supply and open the drain valve, a task you can do yourself if a leak is detected. Have a professional assess and conduct system repair.

Tank explosion

If the temperature pressure relief valve in your gas electric water heater fails, pressure can build up in the tank to perilous levels, potentially causing an explosive rupture. At the first sign of a problem with your gas hot water system, learn how to fix the issue by turning off the heat source and contact a plumber immediately.

Due to the severe risks, it is crucial to have local, qualified professionals inspect and repair your faulty system promptly. Do not attempt DIY repairs unless you have the necessary electrical or plumbing expertise, as mistakes can be deadly.

How long repairs usually take

Repair times for hot water systems vary based on the issue and the parts needed; here are typical estimations:

Minor repairs

Major repairs

Complex repairs, including those on heat pump hot water systems or when replacing elements or tanks, typically require completion by the next day. The plumber may need to order parts or schedule a follow-up appointment to complete the job.

Full replacements

Replacing solar hot water system units entirely usually takes 1-2 days, inclusive of the old unit’s disposal. The old unit must be removed and disposed of properly before the new system is installed.
