In this blog, we’ll help you determine whether your water heater is still fixable or if it’s time for an upgrade. If you’re experiencing issues, Poppy State Plumbing is here to help with expert water heater repair and installation services.
7 Common Water Heater Problems and Whether They’re Fixable
Before deciding to replace your water heater, let’s look at some of the most common problems and whether they can be repaired:
1. No Hot Water
If you turn on the tap and only get cold water, several issues could be at play with your water heaters Marin County:
Gas Water Heaters
The pilot light might be out, or there could be a faulty thermocouple or gas valve. These problems are often repairable.
Electric Water Heaters
A failed heating element or tripped breaker could be the culprit. Heating elements are usually replaceable.
When to Replace
If the heating elements or gas components have been replaced multiple times and your unit is over 10 years old, replacement may be the best option.
2. Water Temperature Issues
If your water isn’t getting hot enough, fluctuates in temperature, or gets too hot, it could be due to:
- A faulty thermostat
- Sediment buildup in the tank
- A malfunctioning heating element
When to Replace
If the thermostat or heating element can’t be repaired or if sediment buildup has caused irreversible damage, replacement may be the better choice.
3. Leaking Water Heater
If your water heater is leaking, it can signify a serious problem. Depending on the source of the leak, repairs may be possible:
Fixable Leaks
If the leak is coming from a valve or connection, a plumber can often repair it.
Unfixable Leaks
If the tank itself is leaking due to corrosion, it cannot be repaired, and a replacement is necessary.
4. Strange Noises (Banging, Popping, or Rumbling Sounds)
Unusual sounds often indicate sediment buildup in the tank. Over time, minerals from hard water settle at the bottom of the tank, creating a barrier between the heating element and the water. This can cause overheating and lead to noise.
Fixable
A professional flush can often resolve the issue.
Not Fixable
If sediment buildup has damaged the tank or heating element, replacement is recommended.
5. Discolored or Rusty Water
If rusty water comes from your hot water tap, it could mean your water heater tank is corroding from the inside. This is particularly common in older units.
Fixable
If the issue is caused by a failing anode rod, replacing it can prolong the unit’s life.
Not Fixable
If the corrosion has spread to the tank itself, replacement is necessary.
6. Water Takes Too Long to Reheat
If your water heater takes an unusually long time to heat water, potential causes include:
- A failing heating element
- A malfunctioning thermostat
- Excessive sediment buildup
If repairs don’t restore efficiency, it may be time for a new, more energy-efficient unit.
7. High Energy Bills
Older water heaters often become less efficient, leading to increased energy costs. If you notice a spike in your utility bills, your water heater could be the culprit.
Fixable
In some cases, a plumbing inspection can be essential to help.
Not Fixable
If your water heater is over a decade old, replacing it with an energy-efficient model can save you money in the long run.
When to Replace Your Water Heater
Even if some problems can be repaired, there are key signs that indicate your water heater is nearing the end of its lifespan and should be replaced.
Age of the Water Heater
Most traditional tank water heaters last 8–12 years, while tankless models can last up to 20 years with proper maintenance. If your unit is approaching or past this range, replacing it is often more cost-effective than repairing it.
Frequent Repairs
If you’ve had to call a plumber multiple times in the last year for water heater repairs, those costs can quickly add up. Investing in a new unit may save you money in the long term.
Persistent Leaks or Corrosion
As mentioned earlier, if your water heater tank is corroding or leaking from the base, replacement is the only option.
Inefficiency and High Energy Bills
Newer water heaters are significantly more energy-efficient. If you’re noticing higher bills and your unit is over 10 years old, switching to a modern model can lead to significant savings.
Inconsistent Hot Water Supply
If your water heater can no longer keep up with your household’s needs, upgrading to a larger-capacity unit or a tankless system may be a better solution.
Choosing the Right Replacement Water Heater
If it’s time to replace your water heater, here are some things to know before choosing a water heater:
Traditional Tank Water Heaters
- Store and heat a set amount of water (usually 30–80 gallons).
- Ideal for families who use a lot of hot water at once.
- More affordable upfront but less energy-efficient than tankless models.
Tankless Water Heaters
- Heat water on demand, offering endless hot water.
- More energy-efficient but higher upfront costs.
- Great for households looking to save space and reduce energy bills.
Hybrid Water Heaters
- Combine tank and tankless technology for better efficiency.
- Use a heat pump to minimize energy consumption.
