How to Prevent a Plumbing Disaster

In our decades of service experience, we have encountered and resolved countless plumbing emergencies. During this time, our Rancho Cucamonga plumbing company has also come to discover that many of these emergencies are entirely preventable.
From burst pipes to overflowing toilets to broken water heaters, there are many plumbing problems that you can avoid by taking good care of your plumbing system.

Our Best Tips & Tricks for Avoiding a Plumbing Emergency:

  • Avoid store-bought drain cleaners: Over-the-counter drain cleaners often contain a ton of harsh chemicals that do more harm than good. If you are trying to clean your drains on your own, use baking soda, vinegar, and hot water instead. 
  • Keep grease, fat, and oil out of your drains: Grease, fat, and oil all harden upon entering your cool drains. Once they harden, they stick to the inside of your pipes and form very stubborn clogs. 
  • Throw food waste away: Your drains can really benefit from you throwing most of your food waste away. Many items such as pasta, eggshells, coffee grounds, and fibrous vegetables can easily get stuck and form very serious clogs within your plumbing pipes. 
  • Only flush the Three Ps: Your toilet is only designed to flush pee, poop, and toilet paper. Any other objects should be tossed in the trash. 
  • Repair minor issues: One of the worst mistakes you can make is ignoring minor plumbing problems. Oftentimes, Rancho Cucamonga homeowners don’t realize that the funny sounds their drains make or the small leak they find are signs of an impending plumbing emergency. Repair any issues as soon as they crop up to avoid serious damage. 
  • Schedule professional drain cleaning: Professional drain cleaning services eliminate drain odors, remove clogs, and keep your pipes flowing freely without causing any harm. Scheduling this service at least once a year can significantly reduce the risk of a plumbing repair or breakdown.
