Backflow Preventer Test and Install in Evansville, IN
A yellow notice from EWSU, a sprinkler backflow device that never got its yearly test, or a new irrigation line, boiler, or pool fill that needs a preventer before it's tied in — that is when backflow preventer test and install work is the job in Evansville.
A yellow notice from EWSU, a sprinkler backflow device that never got its yearly test, or a new irrigation line, boiler, or pool fill that needs a preventer before it's tied in — that is when backflow preventer test and install work is the job in Evansville. The City of Evansville and the State of Indiana both require backflow devices to be installed and tested every year, and at Evansville Plumbing Repair we take those calls around the clock across the Tri-State.
We're locally owned, with a 5.0 Google rating, and backflow work sits under our Water Line & Service Install and Repair category. A backflow device on the supply also traps water heater expansion, so it often travels with expansion tank install work, and high city pressure is a separate fix on pressure regulator install and repair.
Backflow preventer testing
Backflow preventer testing is the job when a device is already in place on an irrigation, fire, boiler, pool, or water-feature line and EWSU's yearly test is due or overdue — not when the line has no device at all, or the assembly failed the last test and needs parts or replacement.
EWSU says residential backflow preventers turn up on lawn sprinkler and irrigation systems, wet fire-protection systems, hot-water heating (boiler) systems, swimming pools, and water features. EWSU runs the Evansville cross-connection program with Aqua Backflow, and the property owner is responsible for getting the test done each year. After the test, the tester hangs a result tag on the device and submits the result to EWSU through Aqua Backflow's trackmybackflow site, where you can track it too.
Indiana's rule, 327 IAC 8-10-8, says each required device is inspected or tested by a cross-connection control device inspector at installation and then at intervals not exceeding one year. Under 327 IAC 8-10-1, that inspector holds a registration number from IDEM. Reduced pressure principle assemblies, double check valve assemblies, and pressure vacuum breakers all fall under that one-year interval in 327 IAC 8-10.
EWSU's page lists testers registered with Aqua Backflow, and a tester not on that list registers at trackmybackflow before testing. We confirm who on our side holds that IDEM registration for your test before we book it, so the tag and the trackmybackflow filing EWSU expects are done right.
Backflow preventer installation
Backflow preventer installation is the job when a new irrigation line, boiler fill, pool fill, or other cross-connection EWSU lists needs a device before it's tied to city water, or when an old assembly failed its test and isn't worth rebuilding — not when a working device only needs its yearly test filed.
Indiana's 327 IAC 8-10-8 has the new device inspected or tested at the time of installation, so a fresh install still ends with a test, a tag, and a result filed with EWSU through Aqua Backflow. Evansville's municipal code takes in the 2012 Indiana Plumbing Code, 675 IAC 16-1.4, which is built on the 2006 International Plumbing Code; houses fall under the 2020 Indiana Residential Code instead, so the rule set depends on the building.
Placement matters past the device itself. Under 2006 IPC 607.3.2, once a backflow device or check valve closes off a supply with a storage water heater, thermal expansion raises pressure and a pressure-control device is required — that's why a backflow install can bring an expansion tank with it. Quotes are free, and there's no trip or diagnostic fee; we're open 24/7 for backflow preventer testing and installation across Evansville and the Tri-State.
FAQ
- Does Evansville require a yearly backflow test?
- Yes. EWSU says the installation and annual testing of backflow devices are required by the City of Evansville and the State of Indiana, and Indiana's 327 IAC 8-10-8 sets the interval at no more than one year.
- Who has to test my backflow preventer?
- Indiana's 327 IAC 8-10 calls for a cross-connection control device inspector who holds an IDEM registration number. EWSU and Aqua Backflow keep a list of registered testers, and the tester files the result at trackmybackflow.
- Where would a house have a backflow preventer?
- EWSU lists lawn sprinkler and irrigation systems, wet fire-protection systems, boiler heating systems, swimming pools, and water features as the usual residential spots.
- Why would a backflow install need an expansion tank?
- Under 2006 IPC 607.3.2, a backflow device or check valve on a supply with a storage water heater traps thermal expansion, so a pressure-control device is required. See expansion tank install for that side of the job.
- Is this the same as a sewer backwater valve?
- No. A backflow preventer protects city drinking water on the supply side under EWSU's cross-connection program. A sewer backwater valve is drainage work, not this Water Line & Service Install and Repair page.
