Ever had your hot water cut out mid-shower? That’s often the first sign that your water heater might be on its last leg. Whether you’re in the middle of winter or just trying to enjoy a warm bath, an unreliable water heater can quickly go from minor inconvenience to a major problem.
In this guide, we’ll cover five clear signs your water heater may need replacing — and point you to a trusted water heater installation company in Simi Valley that can help.
1. Your Water Heater Is Over 10 Years Old
The average lifespan of a traditional tank-style water heater is between 8 to 12 years. Tankless systems may last longer, but even those need regular maintenance and eventual replacement.
Check your water heater’s serial number — usually found on the manufacturer’s label — to determine its age. If your system is nearing or past the 10-year mark, it’s time to start planning for a replacement.
In areas like Simi Valley, where hard water is common, mineral buildup can accelerate wear and tear on internal components, shortening the life of your unit.
2. Rusty or Discolored Hot Water
If your hot water starts coming out with a brownish or rusty tint, that’s a major red flag. Rust inside your water heater tank is often a sign of internal corrosion, which can eventually lead to leaks or a complete system failure.
This isn’t just about appearances — it can also affect water quality and damage appliances. If you’re consistently seeing discolored water, it may be time to swap out the unit.
🔗 According to the U.S. Department of Energy, water heaters are one of the biggest energy users(18%) in your home, and when they’re corroded or inefficient, it’s not just hot water you’re losing, it’s money too.
3. Inconsistent Hot Water or Fluctuating Temperatures
Noticing your water temperature randomly going from hot to lukewarm or even cold? This is a classic sign of a failing heating element or excessive sediment buildup in the tank.
In many Simi Valley homes — especially older ones — this issue creeps in slowly. Homeowners often dismiss it as “just the water acting up,” when in reality, it’s your system telling you it’s time for a checkup.
4. Strange Noises Coming from the Tank
Loud rumbling, banging, or popping sounds are not normal. These noises usually result from hardened sediment at the bottom of the tank, which traps water and causes it to overheat.
This sediment buildup is especially common in neighborhoods like Wood Ranch or Big Sky, where mineral-rich water flows through older plumbing systems.
Besides being annoying, these sounds can signal stress on the tank and may eventually lead to cracks or leaks.
5. Leaks or Moisture Around the Base
Any pooling water or damp spots around your water heater should never be ignored. Small fractures in the tank can expand under pressure, and a full-blown leak can result in hundreds — if not thousands — of dollars in water damage.
Don’t wait until you’re mopping up a flooded utility room. If you notice unexplained moisture or water stains near the base of your unit, call in a professional right away.

Frequently Asked Questions
Q: How long does it take to install a new water heater?
A typical installation takes about 2–4 hours, depending on the type of heater and whether modifications are needed.
Q: Should I repair or replace a 10-year-old water heater?
At 10 years old, most systems are nearing the end of their lifespan. Replacing it may be more cost-effective than frequent repairs.
Q: How do I know if my water heater is still under warranty?
A: Check the label on the unit for the serial number and manufacturer information. Most warranties last between 6 to 12 years and start from the installation date. You can usually verify coverage by contacting the manufacturer directly.
Q: What size water heater do I need for a family of 4?
A: For a family of four, a 40–50 gallon tank is usually sufficient for daily use. However, if multiple people shower in a short time frame or you run multiple appliances at once, consider going larger or switching to a tankless unit.
Q: Can a water heater be repaired instead of replaced?
A: Yes, some issues, like a broken thermostat, pilot light, or heating element, can be fixed. But if the tank itself is leaking or over 10 years old, replacement is usually more cost-effective and safer long-term.
Q: Are tankless water heaters better than traditional ones?
A: Tankless water heaters are more energy-efficient and provide endless hot water, but they come at a higher upfront cost. They’re ideal for households that want to save on utility bills over time and have higher hot water demand.
Q: Do I need a permit to replace my water heater in Simi Valley, CA?
A: Yes, California building codes typically require a permit for water heater replacements to ensure safety and code compliance. A licensed plumber will usually handle this as part of the service.
