How to Know If Your Water Heater is Failing

There are several signs that your water heater may be failing. If you notice any of the following, it may be time to invest in a new water heater.

Corrosion. If you notice signs of corrosion or rust on your water heater tank or see brown and rusty water coming from your pipes, your water heater may be deteriorating. That deterioration could lead to damaging and dangerous leaks if left untreated.
Strange sounds. It’s normal for your water heater to make some noise as it warms up, but any cracks, pops, or other loud sounds could be cause for concern. Unsettling sounds could indicate mineral buildup, mental fatigue, or overheating that could result in your water heater leaking or even failing.
Weird tastes. A metallic taste in your hot water could be caused by your metal water heater tank deteriorating and sending particles into your pipes.
Cold water. A properly functioning water heater should constantly be heating. If your water transitions from hot to cold fairly quickly, your water heater could be failing.
Old age. Water heaters have an expected useful life of approximately 12 years. Look at the sticker on the side of your water heater to see when it was manufactured. If it was made over 12 years ago, it may not be working as efficiently as it should.

How to Select the Right Water Heater for Your Seattle Property

Finding the most efficient and reliable water heater to meet the needs of your home or office is an important task, one that may require the help of a professional plumbing company. Our qualified techs are trained to recognize the type and size of water heater that can best fit your needs.

Our goal is to help you find the best water heater that can save you money on energy costs and provide all the hot water your property requires.

How to Properly Install Your New Water Heater

You may be tempted to install your water heater yourself, but incorrect installation can lead to more expensive, time-consuming, and even dangerous issues down the road. There are several serious issues that could occur if your new water heater is not installed the right way:

An improperly installed water heater can result in leaks and extensive water damage
An incorrectly-piped pressure relief valve can result in electrical short-outs
An ineffectively-vented gas water heater can result in carbon monoxide poisoning

The experts at Bob Oates will install your water heater safely and correctly the first time around, so you won’t have to deal with the hassle!

FAQs About Water Heater Repair

What are the signs my water heater needs repair?

Common warning signs include inconsistent hot water, strange noises like popping or rumbling, rusty or cloudy water, leaks around the tank, or a water heater that takes too long to heat.

How long do water heaters usually last?

Most traditional tank water heaters last 8–12 years, while tankless models can last 15–20 years with proper maintenance. Age and maintenance history are big factors.

Can you repair both tank and tankless water heaters?

Yes. Our team services both traditional tank models and modern tankless systems, providing repairs, maintenance, and replacement when needed.

Do you offer same-day water heater repair in Seattle?

Yes. We provide same-day and emergency service when your water heater fails, so you don’t have to go without hot water.

When is replacement better than repair?

If your water heater is near the end of its lifespan, leaking from the tank, or requiring frequent repairs, replacement may be more cost-effective than ongoing fixes.
