The Invisible Shield for Your Water
You open the tap and expect clean, safe water. But without the right protection, water from your lawn sprinklers, swimming pool, or fire suppression system can be sucked back into your drinking pipes. This is called backflow.
It happens when water pressure drops unexpectedly—like during a water main break. It turns your plumbing into a straw that drinks up fertilizers, chemicals, and bacteria from the ground.
At On Tap Plumbing, we take water safety seriously. We provide the backflow testing and prevention services required by local municipalities to ensure this never happens to your home or business.
We don’t just do the test; we handle the paperwork. We submit the results directly to the city or county so you don’t have to worry about fines or water shut-offs.
Our Backflow Services
We are certified to handle every aspect of backflow prevention.
- Annual Backflow Testing
Most properties with irrigation systems or commercial water lines are legally required to have their backflow preventer tested once a year. We perform accurate, certified tests to verify your device is working.
- Backflow Repair
If your device fails the test or starts leaking, you don’t always need a new one. Our “Warehouse on Wheels” trucks stock rubber kits, springs, and seals for major brands like Watts and Wilkins. We can often rebuild the valve on the spot.
- New Installation
We install code-compliant backflow preventers. We assist with the proper sizing and placement to pass inspection the first time.
Why Choose On Tap Plumbing?
Backflow work requires specific certification. You can’t just hire a handyman.
- We Are Certified: Our technicians hold the specific licenses required to test and repair these safety devices.
- We Are Stocked: A failed test usually means a return trip for most plumbers. Not us. We carry repair kits on the truck. We fix it, re-test it, and pass it in a single visit.
- We Are Clean: Even when working outside, we respect your property. We don't trample your flower beds or leave a mess around the valve box.
Maintenance Plan
Backflow devices have internal springs and rubber seals that wear out. Our maintenance plan tracks your annual testing date so you never miss a deadline. We keep you compliant automatically.
Special Offers and Discounts
We value our community. We offer a 10% discount to military members, teachers, and first responders. If you need backflow prevention services near me, we make it affordable.
Financing Options
If a large commercial backflow assembly needs total replacement, it can be an unexpected hit to the budget. We offer financing options through Housecall Pro so you can get the work done now and pay over time.
