Our plumbing experts explain how to repair the most common causes of water heater failuresr

There is no such thing as a good time for your water heater to fail, and the winter months are a particularly bad time to be left without hot water. It is essential to get professional maintenance for your HVAC system routinely, but even the best-maintained system can fail at the worst time.

While you should call in water heater specialists for any needed repairs and routine maintenance, there are several things you can do yourself to help keep your water heater running smoothly and help troubleshoot any issues if they occur.

When there’s a problem, things can get uncomfortable in a hurry. That’s why you need to understand these essential water heater troubleshooting tips:

No Hot Water

The lack of hot water from your electric water heater is a common problem you can resolve by looking for loose connections and resetting any tripped fuses in the circuit breaker. After about an hour, your home will be resupplied with warm water if the breaker tripped. If the circuit breaker continues to trip, push the reset button and If there’s still an issue, contact a qualified electrician for electric hot water heater repairs.

If you instead have a gas-powered water heater that won’t heat water, the issue is possibly related to the gas supply. Check if the pilot light has gone out, and attempt to relight it.

Low Supply of Hot Water

If your water heater can not produce enough hot water according to your needs, this could be because of one of two things:

  • Your water tank is too small
  • Your aging water heater needs replacing

Perhaps your water heater was more than sufficient when it was just you and your partner. However, when your family expanded, so did your hot water needs. If this is the case, it’s about time you upgrade your hot water tank size. However, if your water heater unit produces less hot water according to its capacity, it might have an issue with one or two heating elements.

Water is Too Warm or Cold

Does the water in your shower feel uncomfortably hot or cold? Your water heater may produce too hot or too cold water because the thermostat is incorrectly set. Fortunately, this is one of the easier solutions to the problem of water that’s too hot or too cold, so it is best to start here. Ideally, you should set your water heater thermostat between 120 and 140 degrees Fahrenheit.

Low Water Pressure

Dealing with low water pressure in the shower can be frustrating. When your hot water pressure is lower than usual, the first thing you’ll likely think of is whether your water heater could be behind the low water pressure issues.

Since many common water heater problems could cause low-pressure issues, knowing where the issue lies is vital. It doesn’t make much sense to replace your water heater only to discover that the problem persists due to corrosion or water line clogs.

Here are several issues that may be causing your low hot water pressure issues:

  • Hard-water buildup in the pipes
  • Partially closed shut off-valve
  • Pipe problems

While a water heater may be the reason behind low hot water pressure, it is far from the only cause. A skilled plumber can help find and fix water pressure problems.

Hot Water Smells

Maybe your issue has nothing to do with the temperature or pressure of your water. Instead, when you run a shower, your hot water comes with an unpleasant odor, maybe smelling like rotten eggs.

Typically, this happens when you leave hot water sitting in your tank for too long. If you don’t smell anything when only running your cold water, the problem likely originates from your water heater. Usually, it happens when warm water sits too long in your heater’s tank, leading to a buildup of bacteria. Unfortunately, there is no easy way to DIY water heater repair with this issue. You’ll need to contact a professional plumber to clean and disinfect your water heater’s tank.

To avoid similar issues in the future, don’t leave hot water in your water heater if you are planning to leave for two weeks or more. Before leaving, ensure that you turn the gas or electricity off to your water heater, and you won’t have any issues.

The Water Heater is Leaking

It’s an unpleasant surprise: You venture into your basement only to splash in a pool of water surrounding the base of your water heater. Since the water heater often sits in a rarely visited area, many tend to fall into that “out of sight, out of mind” trap.

You will likely need a professional plumber to find the source of your water heater tank leak and fix it properly. The good news is that Conejo Valley Home Services Plumbing & Rooter services water heaters in Conejo Valley, San Fernando Valley, and Surrounding Areas, so reach out to us.

Odd Noises in Water Heater Tank

A low, vibrating noise or rumbling noise is most likely caused by sediment buildup in the bottom of the tank. You can fix this by draining the tank to get rid of the sediment, or descaling it with organic chemicals. We don't recommend either of these solutions, though, and chances are that you need a new hot water heater.


» Is it worth it to repair a hot water heater?

Although you can call in an expert to fix most of your electric hot water heater repair problems, whether or not you should do it depends on the cause of the issue, the severity of it, and the age of your water heater.

Frequent water heater repair and major efficiency problems can cost much more than replacing the unit with a newer, more efficient water heater.

» What is the most common problem with water heaters?

Water tank leaks are perhaps the most common type of water heater problem you’ll face. No matter how long it takes, a tanked water heater will eventually start to leak as water slowly corrodes your tank, creating microscopic cracks or fractures.

» Can I fix a water heater myself?

Yes. With the essential tools and expertise, you can save money handling DIY electric water heater repairs in your home. However, should the repairs get too technical, don’t hesitate to seek professional assistance. Just get your phone and look up “ electric water heater repair near me ".

» What are the signs that your water heater is going out?

Unsure if it’s time to replace your water heater? Here are six signs you need a new water heater in your home:

  • The water heater is a decade old or showing signs of age
  • Inadequate heating
  • Recurrent leaki
  • Discolored water
  • Unusual noises
  • Sediment buildup

A home inspection was done for the sale of our home and the inspector flagged our furnace as not having a furnace door switch and being a potential fire hazard. Parker arrived to open the furnace door to find that the switch had a piece of black tape over it to protect it, he removed said tape, job done. Unreal. Thanks Parker.

Gave us an estimate and we decided to wait a few months before booking. I called when we were ready to book, but the person they directed us to never called us back!We ended up choosing another local plumber who charged half what CVHAPR quoted us. I'm so glad we got a second opinion.

Conejo Valley replaced our A/C and furnace in 2014, and just replaced our 20 year old tank water heater today. We switched from tank to tankless and were very impressed with the work. The technicians were very knowledgeable and organized; for us, the installation took only 3 hours as the space was pretty easy to access. I highly recommend Conejo Valley! The office called as soon as they left to check on how the installation went. Great customer service. To the technicians, thanks for your hard work!

Exceptional service from making an appointment with Nancy to Nick repairing leak under kitchen sink. Extremely professional, arrived on time, wear booties (not necessary for me), offered to wear a mask, respectful and neat. Reasonable fair pricing which turned out to be nothing major. I will use them again if needed. Thank you.

Our 20 year old furnace broke down for good over the Christmas break. And it got wet and cold…This team was able to come and quote a new heating system and have it installed, in under 6 days!They were on time, very respectful, and kept us posted continuously throughout the project.We would definitely use them again, and we strongly recommend them!

Art did an excellent job. He stayed late on a rainy day to ensure my drain was working. He talked me thru the entire process and took the extra time to locate the issue and fix it as best he could. He got our drain working and gave us the long term solution and cost. I’d definitely use this company and specifically Art again.
