Snowbird Home Checklist for Sun City Irrigation
A snowbird home checklist for Sun City irrigation: what to test before you leave, how to set the controller for summer and who should check the yard while away.

Before leaving a Sun City home for summer, run and watch every irrigation zone, check drip filters and emitters, set a plant-specific summer schedule, and give a local contact the zone map and irrigation shutoff location. A remote controller can help with adjustments, but a person still needs to spot broken heads, dry beds and storm damage. An EPCOR high-use notice is a backstop, not a substitute for yard checks.
If the house sits empty for the summer, the irrigation runs the hardest months of the year with nobody watching. This snowbird home checklist covers the yard side of closing up a Sun City home: what to test, what to set, and what to leave for whoever keeps an eye on the place.
What should a snowbird home checklist cover for the yard?
Four things: a working system, a summer schedule, a way to stop it, and a person to look. Every item below exists because a summer fault on an empty lot has months to grow. A broken head sprays the wall, a stuck valve runs all night, or a clogged emitter kills a shrub, and the first anyone hears of it may be EPCOR's high-use notice or a SCHOA letter.
Two weeks before you leave: test every zone
Run each station by hand and stand in the yard while it runs. EPA WaterSense lists the checks: heads that do not pop up fully or are tilted, spray that misses its target, coverage that does not reach the next head, and valves that do not shut.
Walk the drip beds too. Sun City water is hard, 7 to 11 grains per gallon according to EPCOR's 2025 water quality report, so open and rinse each drip filter and flush the line ends. A clog that starts in June will not wait for October; the steps are in How to Unclog Drip Emitters in Sun City Hard Water.
How should the controller be set for an empty summer?
For the plants' summer needs, not the household's habits. AMWUA's watering schedules suggest watering turf very early, ideally between 1 and 7 a.m. in warm months, and soaking past the root ball by an inch or two on every cycle. University of Arizona Extension recommends checking root-zone moisture with a soil probe and adjusting frequency for the plant, soil and weather.
Before locking up:
- Remove leftover test programs and extra start times.
- If the controller uses a backup battery, check or replace it and confirm the program survives a power interruption.
- Write the schedule on a card inside the controller door: each station, what it waters, run time and days.
- Note where the irrigation shutoff is, so someone can stop a runaway zone.
- Record a meter reading while all water-using fixtures, appliances and irrigation are off. Show the yard contact how to repeat that no-use check for unexpected flow.
A smart or Wi-Fi controller lets you pause watering from away, but only if it stays online. Confirm the signal reaches the garage wall where it hangs, and have the local contact test that manual control still works. A remote pause cannot repair a broken valve or reconnect a drip line.
What could change while you are gone?
Two things outside the yard: the monsoon and a curtailment stage. The National Weather Service counts the monsoon from June 15 to September 30, the stretch when an empty house is most likely to miss storm damage to heads and exposed drip line. Storm runoff along 111th Avenue now runs into a drainage system the Flood Control District of Maricopa County extended west from Del Webb Blvd to the Agua Fria River in 2022, but yard-level damage is still the owner's to find.
EPCOR's curtailment tariff can also ask for watering cuts while you are away. From Stage 2 it notifies customers in writing at the service address or by mail to the billing address, so make sure mail reaches you or your yard contact.
Who should check the yard while you are away?
Someone who can run the system, not just look at it. Leave that person three things: the controller card, the shutoff location, and permission to call for a repair. Ask for a visit at least monthly, and one after any large monsoon storm.
The visit is short. Run each station for a minute and look for a geyser, a dry bed or a wet patch that does not dry between cycles. Check the meter while all water-using fixtures, appliances and irrigation are off. Check that weeds are not taking over the gravel, because the SCHOA covenants require a weed-free lot and give 30 days after written notice to correct it; the details are in Sun City HOA Landscaping Rules and Your Irrigation.
What should the yard contact do if something changes?
| What they find | Immediate action | What the owner decides next |
|---|---|---|
| Water runs after a station should be off, or the meter moves while all water-using fixtures, appliances and irrigation are off | Close the mapped irrigation supply valve and check whether meter movement stops; report what changed. | If flow stops, arrange irrigation diagnosis before restarting. If it continues, investigate the indoor supply or contact the utility. |
| A dry tree or shrub bed | Check the filter and verify emitter flow, then probe soil at the root zone. | Repair any confirmed fault and adjust the schedule from root-zone moisture and verified flow. |
| A head or exposed drip line damaged after a storm | Stop the affected zone if it is leaking and photograph the damage. | Authorize repair and have the zone retested before its normal program resumes. |
| An EPCOR high-use or curtailment notice arrives | Forward the notice promptly; compare it with the controller card and current meter reading. | Confirm the current EPCOR instruction for this account and adjust the affected schedule. |
EPA WaterSense recommends checking heads, joints and valves for leaks. Arizona Cooperative Extension recommends using a soil probe to confirm water reaches tree and shrub roots. EPCOR's Sun City Water District tariff includes high-use notification and curtailment provisions; it does not guarantee that an alert will arrive before a yard is damaged.

FAQ
Should I turn off my sprinklers when I leave Sun City for the summer?
- Usually not completely, because trees, shrubs and citrus still need water through the heat. Set a summer schedule, test every zone, and leave someone with the shutoff location and the controller card so they can stop a zone that fails.
How often should someone check my irrigation while I am away?
- At least monthly, and after any large monsoon storm. A short visit is enough: run each station briefly, look for geysers, dry beds and lingering wet patches, and check the meter while all water-using fixtures, appliances and irrigation are off to look for unexpected flow.
What happens if my yard turns weedy while I am gone?
- SCHOA can give written notice under the covenants, which require lots to be kept weed free and attractive. The owner then has 30 days to correct it before the association may do the work at the owner's cost. A working system and a yard contact prevent most of this.
Will EPCOR tell me if my water use spikes while I am away?
- EPCOR's Sun City tariff says it tracks each account and contacts customers when use looks excessive for that time of year, by phone, email, mail or in person. Keep your contact details current with EPCOR before you leave.
Do I need a smart controller for a summer away?
- It helps but is not required. A Wi-Fi controller lets you pause or adjust watering from away if the unit and home internet stay online. Test that connection before leaving, and keep a local contact who can inspect the yard and use the shutoff if a pipe, valve or emitter fails.
