Backflow Prevention and Kay Plumbing

Backflow Prevention

Kay Plumbing specializes in residential and commercial plumbing services. Because of the skill and knowledge of our staff, we are able to provide a laundry list of excellent services to fit any situation you might have. If you need a new installation, a remodel, or a repair, give us a call and find out what we can do for you.

Keeping Up with Backflow Prevention

To help out customers, we maintain a digital record of inspection dates and services performed. This helps us, and you, to ensure that your water supply follows South Carolina and local Columbia regulations and building codes. 

We also leave record of test and survey results on the device to prove testing has taken place. Authorities can check the device for verification, and we mail our results to the appropriate regulatory agency, so your records are up-to-date and on file.

Device Test Results:


When Kay Plumbing installs, repairs or tests your backflow device we will leave a Kay Tag on your device with dates and whether you had a pass or fail.  Then,  after completion of each test we mail the results to the appropriate authority to make sure your record is kept on file.
