Sprinkler Controller Replacement and Upgrades in Nashville, TN by TN Irrigation in Nashville and Middle Tennessee
Out with the dusty timer.
The overview

What it is, and why it matters.

Controllers fail from lightning, power surges, moisture and age, and many old models cannot adjust seasonally or run modern schedules. Replacing one is usually quick: label the wires, mount the new controller, connect the common and zone wires and program the schedule. The valves, pipes and heads stay as they are.

We pick a controller with enough stations, add a master valve connection if you have one, reconnect any rain sensor and leave a labeled wiring diagram in the box. In Nashville, where summer storms are rough on electronics, we also recommend surge protection.

Why homeowners choose it

Four things done right.

Every zone wire identified.

Good questions

Controller Replacement & Upgrades: common questions

My sprinkler timer died. Can it be replaced easily?

Usually yes. We replace it with a controller that fits your valves and wiring, program your schedule and test each zone.

Should I buy a smart or basic controller?

Smart controllers adjust to the weather and often pay back through lower water use. Basic ones cost less upfront. We help you choose.
