Common Water Heater Problems in Modesto Homes

Over time, water heaters can wear down from constant use, especially with the hard water common in Modesto. Mineral buildup, corrosion, and age-related wear can result in:

  • Inconsistent water temperature

  • No hot water at all

  • Leaks or water pooling around the tank

  • Unusual noises (popping, banging, rumbling)

  • Discolored or rusty water

  • Foul odors coming from the hot water tap

  • Higher-than-normal utility bills

The good news? Some of these issues are minor and repairable. Others are warning signs that your water heater may be on its last leg.

When to Choose Repair Over Replacement

Repairing your water heater is often the fastest and most affordable option, especially if the unit is relatively new and the problem is isolated. You may only need a simple fix like:

  • Replacing a broken thermostat or heating element

  • Fixing a faulty pressure relief valve

  • Flushing out sediment buildup

  • Relighting the pilot light or replacing a thermocouple

If your water heater is less than 7 years old, hasn’t had repeated issues, and the repair is under $500, our plumbers at Knights Plumbing & Drain usually recommend repair.

We’ll provide a clear quote and explain all your options before doing any work.

When It’s Time to Replace Your Water Heater

Water heater replacement becomes a better option when:

  • Your unit is 8–12 years old or older

  • You’ve had multiple repairs in the past year

  • The tank itself is leaking (not repairable)

  • It no longer meets your household’s hot water demand

  • Your energy bills have spiked due to inefficiency

  • You want to upgrade to a more efficient or tankless model

Replacing your old water heater can also help you qualify for energy efficiency rebates and reduce your long-term utility costs.

Tank vs. Tankless: Choosing the Right Replacement

When it’s time for a replacement, you’ll have two main choices:

Traditional Tank Water Heater

  • Lower upfront cost

  • Stores 30–80 gallons of hot water

  • Great for moderate hot water use

  • Takes up more space

  • Average lifespan: 8–12 years

Tankless Water Heater

  • Hot water on demand

  • Higher upfront cost, but lower long-term energy use

  • Compact and wall-mounted

  • Great for families or high-demand households

  • Lifespan: 15–20 years
