Frequently Asked Questions

Do I need repair or replacement?

When assessing whether to repair or replace, you want to look at how long the part is expected to last with repairs, whether replacing it would let you solve problems that repairs couldn’t solve, and how likely it is to need more repairs soon. Our team can help you consider your options for any situation.

How long do water heaters last before they need replacement?

Depending on how well maintenance was kept up and the quality of the system and installation, a traditional water heater usually lasts between 10 to 15 years. In contrast, a tankless water heater might last 20.

Are chemical drain cleaners safe?

Most chemical drain cleaners are bad options. They rarely solve the root problem causing your clogs and can create much worse situations if they loosen up material on the wall of your pipes without clearing the initial clog—now you have a much bigger, longer clog in place.

Some caustic chemicals can even damage your pipes. Always rely on a plumbing professional to get to the root of the problem.
