If you need a Backflow specialist, Mays Plumbing is the one to call.  We offer backflow inspection, testing, installation, and repair services.  There is confusion around the term Backflow, so here are a few terms to familiarize yourself:  

• Backpressure backflow is caused by a downstream pressure that is greater than the upstream or supply pressure in your potable water system. 
• Back siphonage is backflow caused by negative pressure in your potable water system.  It occurs when there is a stoppage of water supply due to a break in a water main or for other reasons.
