How to identify and resolve leaks in my hot water system?

Introduction to Hot Water System Leaks

Hot water system leaks can harm your water infrastructure, promote mould growth, and inflate utility bills if not addressed quickly. At Seven Hills Plumbing, we expertly identify and remedy leaks in gas water heaters and similar systems.

We are proficient in a variety of heating systems, including storage tanks, tankless units, and those that utilise solar, instant, or heat pump technology. A leak in your plumbing can typically occur due to loose fittings, faulty valves, corrosion, high water pressure, and general wear and tear over time.

As an expert on gas hot water system solutions serving Seven Hills and surrounding suburbs, we’re ready to pinpoint leak locations and execute all necessary repairs. Whether you have traditional water heaters or a more complex system with your heater leaking from intricate parts, we can help.

Locating the Source of the Leak

When dealing with a leak in your hot water system, prioritise safety above all. Make sure to shut off power and turn off water supply and gas before attempting any inspection. Wear gloves and protective eyewear.

• Inlet and outlet water connections
• Temperature and pressure relief valve (also called TP valve)
• Drain valve at bottom of water tank
• Along pipe fittings and joints
• The gas water heater storage tank itself due to corrosion or cracks

Examine these areas for visible water or moisture and feel around joints and valves for dampness. Leaks may stem from worn washers, loose pipes, damaged valves, or system degradation.

Identifying the precise leak location is crucial to determining the repair strategy. We offer assistance in diagnosing leaks across all hot water setups, advising on repair or replacement as needed.

From the Water Tank

It’s essential to inspect the entire water heater, including the top and the bottom, for any indications of leaking. Look along the top and inside tank for any signs of corrosion, cracks, bulges or pools of water. The bottom or underside of the tank are common areas for leaks to occur.

If a severe leak points to a compromised water heater, complete unit replacement is likely necessary, often due to internal corrosion and long-term sediment accumulation.

Sediment build-up at the tank’s base can create leaks beyond pinhole sizes or minor cracks. As internal corrosion worsens, leaks manifest externally, with new water stains on walls or floors being clear indicators.

For new hot water tank installations, enlist a licensed plumber. We can assess the damage, suggest repair or replacement solutions, manage the paperwork, and correctly install your new system.

From Pipes and Fittings

Inspect all pipes, joints, fittings and connections for any water associated with your heater. Look for varying amounts water, moisture, rust stains, mineral deposits or damp areas which may indicate a leak. Pay particular attention to:

• Water inlet and outlet pipes
• Joints connecting pipes to the tank
• Elbow joints and T-joints which can be prone to corrosion or weakening
• Valves
• Flexible connectors

Minor leaks can become major issues if not addressed; tightening loose joints may offer a temporary fix. For corroded pipes or failing components, professional assistance is recommended.

We stock an array of replacement fittings and valves for swift, effective repairs.

From Valves

Valves play a critical role, often being the source of a leak, as your system can rely on them to control and regulate water flow. Key components, vital for effective water heating, include the temperature and pressure relief valve, also known as a TP valve, alongside the drain valve situated at the tank’s base.

Inspect the TP valve carefully for any drips or moisture around the valve opening. A small leak here may indicate the valve needs replacing due to mineral deposits or corrosion preventing it from sealing properly.

A leaking pressure relief valve may result in excessive water pressure, making it wise to check your water pressure at the main meter.

The drain valve may also leak due to a loosened connection or faulty washers. Tightening the valve or replacing worn washers can temporarily stop leaks.

If valves themselves are corroded or damaged, they can also need replacing by a professional plumber to prevent bursts or bigger leaks. Our team carries a range of high quality valves, ready for installation to get your hot water heater back in action.

Temporary Fixes for Minor Leaks

If you have a minor leak in your hot water system that does not seem to be causing any major damage yet, there are some temporary fixes you can try while waiting for a professional plumber:

• Use plumber’s tape to tightly wrap leaking joints or pipe connections
• Tighten fittings, nuts and bolts on pipes that may have loosened over time
• Drain any built-up sediment by opening the drain valve at the bottom of the tank, especially if there’s too much accumulation
• Top up the cold water inlet level if it has dropped below the heating element

While temporary fixes may arrest minor leaks, persistent or deteriorating leaks require professional diagnosis and repair to prevent burst pipes, flooding, and corrosion damage.

We provide affordable, same-day leak detection services that prevent future issues and ensure the accurate identification and repair of leaks in all hot water systems. Whether your tank needs to be turned off due to leaking, or if valves or pipes are the issue, we have the expertise to find the source of the problem and prevent further issues.

When to Call a Professional

There are certain situations when it is crucial to call a professional plumber right away if you have a leak in your hot water system:

• The hot water tank leaking is evident when there is water coming directly from the tank itself, indicating corrosion, cracks or other serious issues
• There is extensive visible water damage on floors, walls or property
• You have attempted temporary fixes but the leak persists or worsens
• When the location where the leak originates cannot be clearly identified after inspection
• There’s no hot water at all due to a potential rupture or burst pipe
• Valves are heavily corroded or damaged and need replacing

Preventing Future Leaks

Diligent maintenance and monitoring are fundamental to preventing leaks in your water system. An annual inspection, flushing, and maintenance routine can help prevent such issues.

Tasks to carry out include:

• Draining water from tank to clear sediment
• Checking pipe fittings and joints for wear
• Cleaning valves and replacing washers if needed
• Inspecting anode rod and replacing if depleted
• Testing temperature and pressure relief valve
• Checking water pressure at the water mains

Installing an electronic leak detector that sounds an alarm at the first sign of a leak is also advised. That way, you can catch problems early before major damage occurs. We can supply and fit these for you.

Regular servicing and monitoring can extend your hot water unit’s lifespan and prevent costly emergencies. We can design a bespoke maintenance plan for your needs.
