Frequently Asked Questions

Whether it’s about backflow devices or commercial plumbing upgrades, we get a lot of questions from our clients. Below, we’ll answer some of the most frequent questions we receive so you can learn more about the topic.


An RPZ backflow preventer prevents contaminated water from flowing backward into your clean water supply. It uses a relief valve with two check valves to protect potable water. RPZ devices are common for commercial applications where the risk of contamination is higher.

Backflow devices need to undergo testing according to your local plumbing code schedule and water authority requirements. Most commercial properties require annual testing to ensure the device is operating properly. A certified backflow tester will inspect and test the backflow device and provide you with the required documentation.

If a backflow device fails, it will need to undergo repairs or even replacement to restore proper protection to your facility. If your device fails during certification, it needs repairs and retesting to pass. It’s important for businesses to address failures promptly to protect the potable water supply and remain compliant with local codes.

I needed a plumber to assist with my bathtub/shower not draining. So I called AP Plumbing, as I do for plumbing issues. The technician corrected the issue with a minor upgrade, and cleaned my tub as well afterwards! Another great AP experience!
