Metro Water Services annual backflow inspection $50 per device, billed by Metro on your water bill

The repair, controller and zone figures come from our 2026 cost guide. The backflow figure is Metro Water Services’ own posted fee, and Metro notes it can change. What pushes a repair up or down:

What sprinkler problems do you fix most often in Nashville?

Broken and sunken heads, valves that stick open or won’t open, cracked lines, controller and wiring faults, low pressure, and freeze damage at spring start-up. Most of it traces back to three local causes: mowers and foot traffic, heavy clay that shifts and holds water, and winters that freeze every year.

How does our sprinkler repair process work, step by step?

Every repair starts with running the whole system, not just the zone you called about. We run each zone from the controller, mark what’s wrong, trace each fault to its cause, price it in writing, fix it, and run the system again. Most head, nozzle and valve repairs are finished in that same visit.

  1. The call. You tell us the symptoms and roughly how many zones you have. You decide whether you want a single fault fixed or the whole system checked. A few minutes.
  2. Zone-by-zone run. We start each zone at the controller and walk it, flagging every head that’s broken, buried, tilted, blocked or pointed the wrong way. Count on a few minutes per zone.
  3. Trace the fault. A dead zone gets tested at the controller, the wire and the valve, in that order, so we replace the part that actually failed. A wet spot gets probed and dug by hand.
  4. Written price. You see the list and the price before anything is replaced. You decide what gets done today and what can wait.
  5. The repair. Heads and nozzles swapped to match the zone, valves rebuilt or replaced, lines cut out and spliced, wires reconnected in waterproof connectors. Simple repairs take under an hour each. A buried line break or valve dig can take a few hours.
  6. Re-run and adjust. Every repaired zone runs again. Arcs and throw get set so water lands on turf and beds, not the street.
  7. Schedule check. We set the controller for the season and show you how to change it. If the rain sensor is dead, you’ll know.

If digging goes beyond hand work around an existing line, utility locating comes first. Tennessee 811 asks for at least three working days’ notice before a dig, and Metro repeats that on its own permit pages.

What does sprinkler head replacement involve?

Replacing a head means digging out the old body, checking the fitting underneath, threading on a matching head, setting it at the right height in the soil, and adjusting the spray. It falls inside the $100 to $400 range for repairs and zone adjustments, and most visits replace several heads at once.

The matching part is what people skip. A rotor and a fixed spray put water down at very different rates, so dropping the wrong head into a zone leaves one patch swampy and another dry. We match the type and the nozzle to what the zone was designed around.

Height matters in Nashville clay. Heads sink over the years as the soil settles and thatch builds, until the spray is hitting grass blades a few inches away. Sometimes a head doesn’t need replacing at all. It needs raising, straightening and a clean nozzle, and that’s an adjustment, not a part.

When should a sprinkler blowout be done in Nashville?

Book the blowout for November, after the lawn stops needing water and before the hard freezes. Nashville’s average first frost is around October 28, and our own lawn calendar lists irrigation winterizing as a December task at the latest. A blowout runs $75 to $150 depending on zone count.

Nashville sits in USDA zones 7a and 7b, where the average yearly low runs between 0 and 10 degrees. That’s cold enough to split any pipe, valve or backflow assembly that still has water sitting in it. A blowout shuts off the irrigation supply, then pushes compressed air through one zone at a time until the heads blow mist instead of water.

The above-ground backflow assembly is the part most exposed to a freeze, and it’s the expensive one. Metro requires a plumber to install or replace it, so a cracked assembly in spring means a plumber, a permit and an inspection before the system can run. A blowout in November is cheap by comparison.

When should sprinklers be turned back on in spring?

Turn the system back on after the last frost, which averages around April 10 in Nashville. That date is a coin flip, since about half of years see a later frost, and the safer date is around April 22. If a late freeze is forecast after start-up, shut the supply off and drain the backflow again.

Start-up is its own service call and a good one to bundle with repairs. The supply gets opened slowly so air can bleed out of the lines, then every zone runs while we look for what winter did. Fescue hits its spring peak in April, but the months that really lean on irrigation here are July and August, so there’s no reason to gamble on an early start.

Does a Nashville sprinkler system need a backflow test every year?

Yes. Metro Water Services inspects and tests every backflow device once a year to meet state requirements, and underground irrigation is on its list of residential cross-connection concerns. The inspection costs $50 per device and shows up on your water bill. A device that fails gets a deadline to fix it, up to ninety days.

Can a sprinkler leak raise my water bill, and will Metro adjust it?

Yes to both, sometimes. Metro bills water by the CCF, which is 748 gallons, and on its 2025 rate table residential use above 10 CCF is charged $6.13 per CCF. A cracked line that runs every cycle adds up fast. Metro says customers with a concealed leak may qualify for a bill adjustment after the repair.

To ask for that adjustment, Metro wants the type of repair and the date it was made. We write both on the invoice so you have them. One more billing detail worth knowing: from April through November, Metro automatically caps residential sewer charges at the winter-quarter average plus 30 percent, because water that goes on a lawn doesn’t go down the sewer. A leak still costs you on the water side.

How should the controller be set after a repair?

Set it to put down 1 to 1.5 inches a week during active growth, rain included, in the early morning. That’s the University of Tennessee Extension figure for fescue, and morning watering lets the blades dry. On Nashville clay, split each zone into shorter cycles so water soaks in instead of running off.

What does a typical Nashville sprinkler repair look like?

These are typical scopes, written as examples and not as jobs we’re claiming to have done. Prices come from our published cost guide. Your own estimate follows the diagnosis, and we’ll tell you which of these your system looks most like before any work starts.

Is it better to repair an old sprinkler system or replace it?

Repair it in most cases. A system with sound pipe and valves is worth fixing a zone at a time, at $500 to $850 for a full zone rebuild against $3,000 to $6,000 for a new six to eight zone system. Replacement starts to make sense when several zones leak and coverage was never right.

This page covers repairs, start-ups and blowouts. If you’re weighing a new system, added zones, drip for the beds or a seasonal service agreement, that’s on our irrigation systems page. Repairs often turn up bigger yard issues too. A spot that stays wet with the system off is a grading problem, and our soil and drainage guide covers that side.
