Frequently Asked Questions

  • Is a Permit Required to Install a Water Heater?

    In most states, including Colorado, no matter where you reside, the answer is yes. The Law requires a building permit when installing a water heater. At Done Plumbing, we always secure the necessary permits and follow up inspections required. This helps ensure the safety of you, your family, or your employees as well as your home or business. It also means you are up to current building codes.

  • Is Carbon Monoxide Detector Required?

    Yes. As of July 2009, Colorado law requires you have a carbon monoxide detector installed within 15 feet of every sleeping area. That means 15 ft or less from the doorway of any room designed for sleeping. You see, your water heater may leak carbon monoxide a colorless odorless gas that can cause death. A detector will set off an alarm to alert you if there is a leak. This law applies to installing or replacing any fuel fired appliance.

  • Should I Have Routine Maintenance Done to My Water Heater?

    Yes. Annual maintenance on your water heater performed by a licensed professional is not only recommended to extend the life and efficiency of the unit, but is required by all manufacturers to keep their warranties in effect. And Done Plumbing can take care of that maintenance on any make or model of water heater to keep it performing at its best.

    You see, without routine maintenance, sediments and mineral deposits can build up leading to higher gas and electric bills, costly repairs, and even complete replacement of the unit. Regularly scheduled routine maintenance is just one of the many ways Done plumbing is committed to helping our customers save money. So when it comes to water heaters, think done plumbing. Whether for routine maintenance, repair, or replacement, remember, one call and its Done!
