Smiley Plumbing provides certified backflow testing, repair and certification to the greater Phoenix area. Backflow prevention systems stop the water in your system from flowing back into the public water supply. It’s clear how vital backflow prevention systems are to keeping water safe and why public health services are concerned with making sure your system is operating properly. Smiley Plumbing prompt service and experience ensures that the backflow certification requirements and backflow codes set by these municipalities are met.
Backflow is the unwanted reversal in the flow of water from a real or possible source of contamination or pollution back to the public clean water supply.
There are 2 types of backflow:
Backpressure: Occurs when the user system is at a higher pressure than the supply water systems allowing undesirable substances to be “pushed” back into the potable water system.
Backsiphonage: Occurs when negative or reduced pressure exists in the supply piping allowing undesirable substances to be “drawn” into the potable water supply.
A couple of simple devices are available that ensure that water can only pass through a pipeline the correct direction:
Why Test Backflow Preventers?
Mechanical backflow preventers just like many plumbing systems have an internal seal, springs, and many moving parts. Like any tool of this nature, inefficient usage, wearing out, and breaks are possible. Not only are these systems subject to damage but they can also be bypassed. This is why it is necessary to insure they are functioning properly. Sometimes a visual check will do, but all mechanical backflow preventers have to be tested with specialized, properly calibrated equipment. Smiley Plumbing has the backflow testing equipment and backflow prevention expertise to handle your backflow issues.
Just a note to let you know how pleased we were with the work your plumber did for us this morning. He was very personable, explained everything and best of all, I had no cleaning up to do after he left. He's our kind of plumber! If the need arises, we'll surely call you in the future.- Dorothy O'Neil
