Is your water heater sounding like a coffee percolator or a construction site? Strange noises coming from your water heater can be unsettling, but understanding the cause is the first step to resolving the issue. Let Pure Plumbing & Drain dive into some common reasons why your home water heater might be making noise and what you can do about it!
Sediment Buildup
A frequent culprit behind noisy water heater installations is sediment accumulation. Over time, minerals like calcium and magnesium can settle at the bottom of the tank, forming a layer of sediment. As the water heater heats up, these sediments can cause rumbling, popping, or banging sounds, often referred to as "kettling."
Solution: Flushing your water heater regularly (usually once a year) can help remove sediment buildup. If the problem persists, you might need to call a professional residential plumber for a thorough cleaning.
Overheating
If your water heater's thermostat is set too high, the water inside can overheat and boil, leading to more energy usage and excessive wear and tear. This can also create a dangerous situation, as the hot water can lead to scalding.
Solution: Check your water heater's thermostat and lower the temperature setting to the recommended level (typically around 120°F or 49°C). If the noise continues, consult Pure Plumbing & Drain to inspect the thermostat and heating element.
Pressure Issues
Unusual noises can also stem from pressure-related problems. If the water pressure in your home is too high, it can cause the water heater to work harder and produce banging or knocking sounds. Similarly, a faulty pressure relief valve can lead to hissing or whistling noises.
Solution: Install a pressure regulator to manage the incoming water pressure. If you suspect a problem with the pressure relief valve, have it inspected and replaced by a qualified residential plumber.
Clogged Drain
A clogged drain can also cause the water in your water heater to make noises, especially gurgling sounds. This is due to the water having trouble flowing through the drain, causing air to become trapped and create these sounds.
Solution: Contact a plumber for drain cleaning services to remove any obstructions and ensure proper drainage.
Time for an Upgrade?
In some cases, a noisy water heater is simply a sign of age. As water heaters near the end of their lifespan (typically 10 to 15 years), they become more prone to sediment buildup, corrosion, and other issues that can cause noise. If your water heater is old and inefficient, it might be time to consider a new water heater installation.
Solution: Have Pure Plumbing & Drain assess the condition of your water heater and provide recommendations for repair or replacement. Newer, energy-efficient models can save you money on your utility bills and provide a more reliable hot water supply.
