"John arrived as scheduled. Very personable and skilled. I had purchased a needed replacement part for the toilet, but it needed additional parts and he had them in his van. Now my toilet flushed like new! Will use his services again for future projects."

"I posted the plumbing need on Sunday late afternoon and almost immediately had a response from David at Mayan!! After a few texts and photo exchanges, we scheduled a time to connect on Monday. David was timely in arriving, reviewed the project scope and immediately got to work. Project was completed more quickly than I expected and David even solved another plumbing issue I was having -free of charge! Great work, great work ethic along with a personable, and professional manner. Would highly recommend David (Mayan Plumbing) to anyone with plumbing issues!"

"Ron wrote me a quote to replace a leaky interior 40 gal tank water heater with an exterior tankless water heater. After comparing with other quotes, we chose to go with Ron for several reasons, but mainly because of his years in the business, willingness to discuss concerns and answer questions, and his itemized quote. Ron kept me up to date with changes when the unit he ordered was delayed. He showed about 30 minutes early day of install to get a head start on some weather. During the install, he welcomed questions and explained everything to my satisfaction. We made modifications to the work, deciding not to do the sheetrock replace or electrical (contracted separately) and this was reflected in the quote. The work was timely and well done. He and his crew cleaned up well after. The price I paid him was under the estimate. I would use him again in the future."

Water Heaters FAQs, answered by experts

The chemicals in a water softener can wear down the anode rod in the heater and shorten its life span. However, for most people, the benefits of the softener outweigh this potential drawback.

Have a plumber inspect the anode rod annually for damage, as replacing the anode rod is far less expensive than replacing the entire water heater.

Every city and state will have its own set of installation codes and laws. Some won’t require you to obtain a permit before replacing your water heater, though we recommend you do, regardless of the local codes. On the other hand, some cities and states might require secondary permits for plumbing and electrical work related to the installation. Check with a local water heater installation company and local building codes to confirm which permits are required and what the specific laws are.

Homeowners insurance may cover the repair or replacement of a water heater if it's damaged by a covered peril, such as a fire or a burst pipe. However, policies typically do not cover repairs or replacement needed due to normal wear and tear, old age, or lack of maintenance. For these issues, a home warranty or a manufacturer's warranty may provide coverage. While the policy might not pay to fix or replace the malfunctioning appliance itself, it often covers the cost of water damage restoration caused by the faulty water heater. Always check with your insurance provider to understand the specifics of your policy.

The standard copper wire gauge to use with any 30-amp circuit is a 10-gauge wire. The National Electric Code specifies a 10-gauge wire with appliances like water heaters running on 30 amps. If you try to use a smaller gauge wire, such as a 12 gauge, with a 30-amp breaker, you run the risk of the wire overheating and melting or causing a fire. Because of the safety hazards, the gauge of the wire is not an area to try to cut costs when connecting a 30-amp breaker to a water heater.

It takes between one and three hours to replace a hot water heater element, depending on whether you hire a pro or do the work yourself. For example, a professional plumber with all the necessary tools and experience can often finish the job in one to two hours, whereas DIY will take two to three hours because it'll involve more preparation and troubleshooting.
