Sprinkler System Expansion in Middle Tennessee

Adding heads to an existing zone is the wrong fix and the most common mistake we find. Stretching a zone beyond its flow capacity drops pressure across every head on it, so instead of gaining coverage you lose it everywhere.

We test static pressure and available flow, count what the existing zones already demand, and check whether your controller has spare stations and whether the valve manifold can take another valve. Then we add real zones sized correctly.

Yard projects change watering needs. A new patio removes turf, a fence line adds a strip that the old spray pattern no longer reaches, and a pool surround introduces hardscape you do not want soaked.

When irrigation work happens alongside fence or hardscape work, we sleeve under new hardscape and route lines clear of post holes so nothing gets cut later.

During an expansion we usually find tilted heads, sunken heads mowed over years ago, mismatched nozzles on the same zone and a controller schedule nobody has touched since installation. We correct those while we are in the yard, because a well designed new zone next to three broken old ones still gives you a patchy lawn.

An expansion is only straightforward if the existing system has capacity. We check the controller for available stations, the mainline size, the backflow device rating and the actual flow at the connection point before quoting additional zones.

Sometimes the honest answer is that the existing system was built to its limit and a proper expansion means a controller upgrade or a second point of connection. We would rather tell you that up front than bolt zones onto a system that cannot feed them, which leaves you with worse coverage everywhere instead of good coverage in one more area.
