Irrigation Leak Detection in Greeley, CO

Sprinkler systems leak in ways you cannot see. A buried line can break and lose water for weeks with no puddle on the lawn. A stuck zone valve can trickle all night. Irrigation leak detection in Greeley, CO finds these hidden leaks and tells you which zone, valve, or pipe fails.

This matters more in Greeley than in many cities. The city bills single-family homes on a water budget with four tiers. Outdoor leaks push you into higher tiers fast. A small leak on a sprinkler line can cost real money before you spot a wet patch.

Signs your irrigation system is leaking

Look for these clues, even when the grass looks fine:

• A water bill that spikes in summer. You expect some rise, but a big jump points to a leak.
• A meter that moves when the sprinklers are off. Shut off every zone and watch the meter.
• Soggy patches or mushy turf. One zone may stay wet for days after it runs.
• Low pressure at the heads. Sprays look weak or miss their pattern.
• A zone that never seems to stop. A stuck valve keeps water flowing.
• Dry spots next to wet spots. Water leaves the pipe before it reaches the far heads.
• Mud or sinking soil near a valve box. Water may sit inside the box.
• Lush, bright green grass in one strip. A leak feeds that line with extra water.
• Runoff onto a sidewalk or street. Check heads, but also check the line below.

Not every sign shows up. Many irrigation leaks leave no sign at all. That is why a meter test and a pressure test matter.

Where irrigation leaks hide

Sprinkler lines are shallow. Most are plastic pipe, often PVC or flexible poly. They fail in predictable places.

• Zone valves and valve boxes. A worn diaphragm or a failing solenoid lets water seep past a valve that should stay shut.
• Fittings and couplings. Joints crack from soil movement, freeze damage, or a poor glue job.
• Sprinkler heads and risers. A lawn mower, a footstep, or age can break a head or riser.
• The backflow assembly. This device guards the house water supply. It can leak at its test ports or body.
• The main line. The main line stays under pressure all the time. A leak here drains water even when no zone runs.
• The point of connection. Where the irrigation line tees off the house supply, a fitting can fail.
• Wire splices. These do not leak water, but a failed splice can leave a valve stuck open.

Freeze damage causes many of these. If a line holds water through a hard freeze, it can crack. The break may only show up next spring when the system turns on. See our guide to a sprinkler blowout leak check before the first hard freeze.

How we find an irrigation leak

We start with the meter, then work down the system.

1. We read your meter. With every indoor fixture off and every zone off, we confirm that the dial moves.
2. We isolate the irrigation system. We close the shutoff that feeds the sprinklers. If the meter stops, the leak sits in the irrigation system. If it keeps moving, the leak sits elsewhere. See our water line page for that case.
3. We split the system into zones. We test each zone, one at a time, and watch the meter.
4. We check the main line under pressure. We pressurize the line that stays live between zones and listen for the leak.
5. We inspect valves and boxes. We open each valve box and look for water, worn parts, and seeping valves.
6. We pinpoint the break. We use listening gear and, when needed, a pressure test to narrow the leak to a small area. We mark it with a flag or paint.

We do not need to dig up your lawn to find a break. We only dig at the repair spot.

Irrigation leaks and your Greeley water bill

Greeley bills each single-family customer against a water budget. Use at or below the budget costs the lowest rate. Use above it moves you into higher tiers. The city's rate page explains that the budget reflects efficient use for your lot size and household.

That setup rewards finding leaks early. A broken sprinkler line can burn through hundreds or thousands of gallons per day. Even a slow leak can push a summer bill into higher tiers. Our guide to Greeley water budgets walks through how the tiers work and what to do when your bill jumps.

The EPA says household leaks can waste nearly 10,000 gallons of water a year. It adds that leaks may raise a bill by up to 10 percent. A sprinkler leak often wastes far more than a dripping faucet.

The Greeley irrigation season

Greeley sets lawn-watering rules each spring. In a normal year, the schedule has run from about April 15 to October 31. The city bans overhead watering from 10 am to 6 pm. The city says it posts the rules every April, so check the current schedule.

The system sits idle most of the year. Leaks often start in winter and show up at the first spring test. We suggest checking your system when you turn it on, and again mid-summer.

What to do before you call

Take these steps first. They help us find the leak faster:

• Run each zone for a few minutes. Note any zone with weak sprays or soggy spots.
• Check the valve boxes. Lift the lids and look for standing water. Do not reach into a box that holds water.
• Look at your meter. Note the numbers with all zones off.
• Mark suspect spots. Stick a flag in the ground where the turf looks wet or sunken.
• Shut off the sprinkler supply if it keeps running. If a zone will not turn off, close the irrigation shutoff.

Do not dig without calling 811. Public utilities mark their lines, but they do not mark the private irrigation lines on your property. The Colorado 811 site explains how to request a locate.

What happens after we find the leak

We mark the leak and write up what we found. Then you can choose who repairs it.

• A sprinkler or lawn care company can fix a broken head, valve, or fitting.
• A licensed plumber can fix a leak near the house supply or the backflow assembly.
• Your own tools may handle a cracked head or a loose fitting, if you are comfortable.

Because we only do detection, we do not push repairs. We give you the facts.
