Vacation and Seasonal-Home Plumbing Shutoff Checklist
An Arizona vacation home plumbing checklist starts with identifying every domestic, irrigation, and treatment control point in the house, then deciding — using equipment manuals and any HOA or insurer requirements — what gets shut off, what stays running, and who checks the property.
Build a Property-Specific Departure Plan
No single checklist fits every West Valley property, because no two homes shut off the same way. Build the plan around five decisions: what to inventory, what to shut off, what stays running, who checks the house, and how you’ll be alerted if something goes wrong.
Inventory Domestic, Irrigation, Fire, Pool, and Treatment Systems
Main Water Shutoff Versus Irrigation Control
Decide What Remains On Using Verified Requirements
Don’t guess — check your HOA’s landscaping rules, your insurance policy’s vacancy clause, and the manufacturer’s vacation-mode instructions before finalizing the plan.
Water-Heater Vacation Settings Require the Exact Manual
Tank versus tankless, gas versus electric, and different manufacturers all handle standby differently. Stop and use the manual, not a guess, if you’re unsure whether the unit has a true vacation mode, or the task involves the gas valve or breaker.
Water-Softener Bypass and Regeneration Planning
Appliance Supply Lines, Toilets, and Visible Fixtures
Shut off the ice maker and refrigerator line — a commonly cited source of a slow, unnoticed leak. Close washing machine supply valves, and walk every visible fixture once for a running toilet, a slow drip, or an aging supply line.
Trap Seals, Drains, and Sewer-Gas Considerations
Arizona’s low humidity can fully evaporate a trap’s water seal over a multi-month absence. A sewer-gas smell on return is usually a dried trap, not a sewage problem — add water plus a few ounces of mineral oil to each trap before leaving to slow evaporation.
Leak Sensors, Smart Meters, and Alert Contacts
A sensor can flag unusual flow at its own location — it cannot identify which fixture is responsible without someone physically checking. Ask whether it needs cellular service, who receives the alert, and whether it shuts off water automatically or only notifies.

Monsoon-Season Additions to the Checklist
If your absence overlaps June 15–September 30, confirm gutters and roof drains are clear, ask your local contact to check for standing water after storms, and leave irrigation/backflow access clear. See the full monsoon plumbing checklist.

Frequently Asked Seasonal-Home Plumbing Questions
Should the home’s water be shut off before an extended absence?
For most Goodyear homes, a full main shutoff is the single most effective step. Some owners choose a selective shutoff instead, trading some protection for keeping landscaping alive — verify which fits your HOA and insurance requirements.
How do domestic water and irrigation shutoffs differ?
The domestic main controls everything inside the house, while irrigation has its own backflow preventer and zone valves managed independently. Most seasonal homes leave irrigation running and shut off the domestic side.
What heater and softener settings require the exact manual?
Any vacation or bypass mode beyond a simple valve closure, since tank versus tankless and different manufacturers all handle standby differently.
What should a local contact inspect while the home is vacant?
A visual walkthrough for standing water, odors, unusual sounds, and any leak-sensor alert. They shouldn’t attempt repairs — their job is to observe, document, and call the right contact.
What should be checked before returning plumbing to normal use?
Inspect visible supply lines and the water heater before turning the main back on, then open it slowly while watching the meter. Refill every trap and replace aged supply lines before relying on the system daily.
Should the water softener stay in regeneration mode or bypass during vacancy?
Most owners bypass the softener when nobody’s using water, since a scheduled regeneration with no use wastes salt for no benefit.
Does this checklist change during monsoon season?
Yes — any absence overlapping June 15 through September 30 benefits from storm-specific additions: clear gutters beforehand and a post-storm check for standing water near the foundation.
Who should keep a copy of the valve-position photos and emergency card?
Keep one copy with your local contact, since they’re most likely to need it in an emergency, and a second copy with you or in cloud storage you can reach remotely.
