Water Heaters

Did you know that the average water heater lasts between twelve and fourteen years? Yours can last longer if you’re lucky and take good care of it, but that’s the average. 

Whether you need water heater repair, water heater installation, or a total water heater replacement, Dwyer Plumbing can help. We have been in the plumbing business since 1922—hot water tank repair is kind of our thing.

Here are a few signs that your need for a hot water heater repair is imminent:

Your Water Heater is Noisy

All appliances make a little noise, but if your water heater (whether it’s a gas water heater or an electric water heater) seems particularly loud, it might be time to look at having it inspected and potentially repaired. Water heater noise to watch out for can be crackling, rumbling, or popping sounds.

Your Water Heater is Old

If your water heater is approaching its tenth birthday (or if it’s even older), it’s time to give Dwyer Plumbing a call! We can come inspect your water heater and make any repairs before they become costly problems. 

You Have No Hot Water

If your water heater isn’t doing its job by giving you hot water, this is a clear sign that something’s up. (Unless it’s been super cold outside; this can make your water heater work harder.) For gas water heaters, a pilot relight might do the trick. If you have an electric water heater, take a peek at your circuit breaker. If there isn’t a problem with either of these and you’re shivering in your shower, call us: it’s probably time for a repair. 

Your Water Heater is Leaking

A leaking water heater is a clear indication that something is amiss. A water heater is not supposed to leak, so if you find water around your water heater unit, you can first check around the heater’s connections, fittings, and temperature pressure relief valve. If all looks well, your water heater may be due for repairs to find and fix the problem.

In addition to the above problems, your water heater probably needs repairs if your water is discolored or tastes weird or metallic.

Water Heater Replacement and Installation

If you catch a water heater problem early enough and call us for regular water heater inspection and maintenance, you and your gas or electric hot water heater can enjoy a relatively long relationship together. But if your water heater is reaching that decade milestone and you’re experiencing issues, a water heater replacement might be in your best interest.

There are other reasons you might need to replace your water heater entirely: maybe your home or business isn’t getting enough water. Or maybe the previous homeowner didn’t have a large family, and the hot water tank size was large enough to keep up with their needs—but not yours. 

We replace and install all major water heater brands including Ruud, A.O. Smith, and State. If your water heater falls outside these brands, call us; we can help. We repair, replace, and install gas water heaters, electric water heaters—even the newer, more popular tankless water heaters!
