Backflow Preventer Testing in Portsmouth, VA
Annual inspections, repairs and installation for the device that keeps used water out of your clean supply, from a backflow certified crew on Turnpike Road.
Chapter 01
What a backflow preventer protects
A backflow preventer is the valve that keeps water moving one direction only, out to a fixture, an irrigation line or a boiler loop, so that if pressure in the street main drops, nothing already inside your plumbing gets pulled back into the clean supply. Most homeowners never think about the device until a test comes due or something changes nearby on the line. It sits quietly doing its job until it does not.
A handful of things tend to be the tip-off that it is worth a look: pressure that suddenly feels different than it used to, water that comes out discolored, a smell you cannot place, or water pooling near the device itself. None of those on its own means something is broken, but together they are worth a call rather than a guess.

Annual inspections, repairs and installation
Ellsworth Plumbing & Heating is backflow certified, and testing, repairing and installing these devices is routine work for the crew, not a specialty they farm out. An inspection checks that the valve is actually doing what it is built to do: holding water back under the conditions that would otherwise let it siphon the wrong way.
If a device fails, we repair what can be repaired and replace what cannot. New installations get set up and tested on the spot before anyone leaves the property, so you know it is working rather than taking it on faith.

Keeping the annual test on the calendar
Some backflow devices need testing every year, others less often, depending on the property and how it is plumbed. We are not going to tell you what your situation requires; that call belongs to whoever set the requirement in the first place. What we can do is test it, tell you plainly what we found, and keep it on a schedule so it is not something you have to remember on your own.
Call (757) 250-2677 and we will get you on the calendar. We work Monday to Friday, 8 to 5, with estimates as soon as the next day and service within 1-2 business days once the job is scheduled.
Backflow certified, fully licensed and insured, with a 1-year warranty on every new installation.
