Backflow Prevention in Pasadena
Keep Your Glendora Business Safe & Compliant with Merry San Marino Plumbing
Our public water supply is one of the single most important civil service projects that has ever been built. We depend on the water flowing through these main water lines for just about everything. Whether it’s water running from your taps or showers or the water that’s used to irrigate your landscaping, we depend on this water remaining clean and free from potential contamination. However, when certain plumbing devices present a risk of allowing contaminated water to flow backward through water lines, it’s vital that you have a working backflow prevention device to stop this. It’s so vital, in fact, that it is required by law for all businesses and even some residential properties.
Here at Merry San Marino Plumbing, we offer a full range of services for backflow prevention devices in Pasadena and the surrounding communities, including comprehensive testing and certification as well as repairs, new installations, and more. This is why our municipal governments have such strict codes for keeping your water safe, especially through the method of backflow testing and prevention. When water flows in the wrong direction, it can carry harmful pollutants, particles, and other contaminants into your drinkable water system. At our company, we make sure the water supply is safe by offering licensed testing and certification as well as comprehensive services for devices that fail their annual exam.
Call us today at (626) 414-5583 to get immediate same day service for your Pasadena backflow testing issues.
Understanding the Causes of Backflow
“Backflow” is the term used to describe the phenomenon when water actually flows backward through your water lines. There are a few ways this can happen, but more often than not this happens when the pressure inside your water lines exceeds the pressure of the water entering through your meter. While this isn’t really an issue in most residences, any time that potentially contaminated water could flow backward through internal water lines could be dangerous to our water supply. Broken water mains or burst fire hydrants can also lead to backflow, resulting in possible main line contamination.
Backflow could be caused by any of the following:
- The water main or primary distribution pipe becomes fractured or broken
- Improper plumbing work results in prolonged drainage buildup
- Huge amounts of water are utilized by firefighters during situations of emergencies
- Sudden power outages, often caused by extreme weather conditions such as storms or intense bouts of heat
Types of Backflow Preventers You Should Know
Backflow prevention devices come in a few different varieties, based primarily on the type of building you’re in, the amount of water you use, and the amount of water pressure you require. Regardless of the type of prevention you have, the state of California requires that you have the device tested annually. This test usually takes about an hour or two and does require that your water is shut off for a short amount of time in order to complete.
