Commercial and Residential Backflow Testing and Repair

Backflow Services

Alexander Services provides certified and licensed commercial and residential backflow tests and backflow services in the greater Raleigh, NC area. Our expert backflow prevention plumbing technicians can provide you with your yearly backflow testing requirements, repair any problems if needed, and provide your local municipality the testing report annually when complete.

Commercial Backflow Testing

Every commercial building in North Carolina requires an annual certification of the backflow preventer. Every commercial building in North Carolina must have a passing test report submitted annually. We can provide you that testing of the backflow prevention device and if we find any problems, we can also repair the problem detected to pass the test. After the testing is complete, we provide your test results directly to the municipality on your behalf..

Residential Backflow Testing

If your home has a sprinkler system for your lawn, your sprinkler system must have a yearly backflow preventor to prevent any contaminated water mixing with your drinking water. The backflow preventer must be certified by a trained plumber or backflow technician. Using your sprinkler system with a damaged backflow preventor could allow chemicals, pesticides and herbicides to enter into your home’s drinking water and cause health risks to you and your children. After the test, we will take care of providing your municipality the results of the test.

Backflow Repair

Before any backflow repair can be done, the cause of the problem must be determined first. Only a professional plumber with vast experience in these affairs can run such diagnostics accurately on your plumbing system. Once it has been fully established that issues like small leaks or clogs aren’t the cause of the backflow your pipes and showers are experiencing, then the option of getting backflow repairs comes in.

The technicians were very professional and communicated very well about what they were doing. They worked outside in 90+ degrees and through a rain storm. I would recommend them for any plumbing services in the future.

I was able to get an appointment to tune up my AC unit the week following the week that I called. The technician was on time - wore a mask, gloves, and shoe coverings and endeavored to stick only to the thermostats and unit in the attic and went around to the back (I live in a town home) without going through my home. I truly appreciated this approach. The unit was serviced and the cost was very reasonable. I “found” this company because my daughter uses their services too and has been very happy with them.
