Stagnant water in an old heater can lead to mold growth and the release of harmful chemicals. Maintenance and replacement are crucial for safe hot water use.

Legionella bacteria loves warm, moist environments – like water heaters. Ingested or inhaled through steam or aerosolized droplets, it can cause pneumonia. Symptoms include fever, coughing, shortness of breath, muscle aches, and headaches.

Sediment – minerals like sulfate and magnesium – can build up in the tank. This affects taste, quality, and damages appliances & drains. It also reduces heating efficiency by insulating the element from the water, leading to higher energy use.

Leaks or rust due to corrosion can also develop. This creates a moist environment for mold to grow. Mold spores can cause respiratory issues like allergies & asthma. Plus, if your home has lead pipes, a faulty heater may contaminate drinking water with lead particles.

Regular maintenance & replacements can prevent these risks. Flushing the tank removes sediment & checking valves for leaks ensures proper functioning. If you smell rotten eggs or have low hot water pressure, get a professional inspection ASAP!

Don’t ignore the warning signs of a bad water heater. Invest in a new one for clean & safe hot water. The health risks of an old or malfunctioning heater are not worth it – act now to protect yourself & your family.

Signs of a bad water heater

When your water heater goes bad, it can bring a range of issues and health risks. Here are some signs to watch out for:
