How to Take Care of Your Plumbing System

Your family relies heavily on a properly functioning plumbing system to get through each day. To ensure your system doesn’t break down at the worst possible time, our Duarte plumbing company recommends becoming familiar with some of our best maintenance tips.

To Prevent a Plumbing Problem & Keep Your System in Top Shape, You Should:

  • Never use over-the-counter (OTC) products: OTC drain cleaning products have been shown to cause significant pipe corrosion, which leads to cracked or burst pipes and premature plumbing failure.
  • Schedule professional drain cleaning: Professional drain cleaning services blast away buildup, eliminate drain odors, remove clogs, and keep your pipes flowing freely all without damaging them. When the time comes to unclog or clean your drains, schedule an appointment with a team of Duarte plumbing professionals.
  • Flush your water heater: Over time, your water heater fills up with sediment, which can cause it to slow down, become clogged, and malfunction. Make sure to have a professional plumber drain the sediment from your water heater 1-2 times per year.
  • Be careful with your drains: Many people tend to put clog-forming, drain-damaging items down their drains without even realizing it. To avoid a plumbing disaster, you should only flush human waste and toilet paper down the toilet, limit the amount of food waste you place in your garbage disposal, and use a drain trap in your shower to keep hair out of your drains.
