Schedule Backflow Testing Services for Your Midlands Business
If you have a backflow preventer in your plumbing system, it’s important to have it tested at least yearly to make sure it’s functioning properly. Depending on what type of commercial property you have, you may be legally required to test it at regular intervals. Kay Plumbing is qualified to inspect your backflow preventer.

Keep Your Staff and Clientele Safe with Backflow Testing Service
A bad backflow preventer can seriously impact not just your reputation as a business owner, but it can affect your staff, customers, and even the local environment. You may already be legally required to have a regular backflow inspection, but even if you’re not, you should do it at least once a year. Kay Plumbing can test your backflow preventer, make sure it’s still up to par, and help you avoid unnecessary business closures.
Backflow Testing, Repair, and Preventer Installation Services

Backflow Testing and Inspection Services
With backflow testing, a certified plumber can verify that your water is entering your plumbing system as it should, that there are no leaks, and that all parts of your backflow preventer are in working order. This should be done at least once a year, and depending on your company, there may be a legal requirement for it.

Backflow Repair Services
If some part of your backflow test fails or you notice signs of a broken backflow preventer, it’s important to have a qualified plumber to diagnose and fix the problem. Kay Plumbing will arrive on time, and we can generally get your backflow preventer up and running again on your schedule, preventing unnecessary downtime at your property.

Frequently Asked Questions
How often should I have my backflow preventer tested?
How often you should test your backflow preventer depends, but at least once a year is a good rule of thumb. Depending on what kind of business you operate, your municipality may have legal requirements on how often you need backflow testing services. Regular maintenance is the best way to prevent unexpected repairs.
Do I need a backflow prevention device?
If there’s a chance wastewater and potable water can interact – like in a closed plumbing system – then you need a backflow prevention device. Depending on your company, you may need one to meet local code and legally operate.
Why is a backflow preventer important?
A backflow preventer is important because it keeps water moving in one direction, meaning wastewater won’t back up and mix with water in the main line or come back into your water supply. Potable water contamination can cause illness for everyone consuming your water.
How do I know if I'm getting backflow?
You won’t always immediately notice your backflow preventer is broken. Here are a few signs to look out for:
- You have leaks, but there’s no obvious cause for them.
- Check valves make unusual noises.
- Your water is discolored, has a bad odor, or tastes strange.
- You have bad water pressure.
- Your water drains slowly.
- Your staff and customers are becoming physically ill, and your water is the only common connection between them.
