Outdoor Faucet Winterization — Ohio Homeowner Checklist

Every February I get the same call. Homeowner went into the basement, found a puddle, traced it up the wall, and realized the hose bib above the laundry room burst sometime in January. The repair runs $400 to $1,500 depending on what got soaked and how fast they caught it. All of it preventable with about an hour of work in October.

I have been winterizing irrigation lines, outdoor faucets, and landscape water features for clients across Pickaway, Franklin, and Fairfield counties for more than a decade. Here is exactly what I do, in order, on every property before Halloween.

When should I winterize outdoor faucets in Ohio?

The last week of October is the right window in Central Ohio most years. You want to be done before the first hard freeze, defined as overnight lows below 28 degrees for several hours. NWS Wilmington data shows our average first hard freeze for the Columbus/Circleville corridor lands between October 25 and November 5, with about a one-week shift in either direction depending on the year.

You can be a couple weeks early, no harm done. Being two weeks late is what fills the basement.

On a Columbus Hilliard property last Friday, the homeowner had me winterize her irrigation system the same week we did her final mow and gutter cleaning. Bundling the fall tasks into one visit saves a service charge and means nothing gets forgotten. That is the whole point.

What gets winterized exactly?

Five categories on most Central Ohio properties:

• Frost-free hose bibs (the outdoor faucets attached to the house)
• Standard hose bibs (older homes still have these with an inside shutoff)
• Irrigation systems (in-ground sprinklers with backflow preventers)
• Outdoor kitchens and pot fillers
• Decorative water features and ponds

If you have all five, budget two hours. If you have just hose bibs and no irrigation, budget twenty minutes.

How do I winterize a frost-free hose bib?

Frost-free bibs are the long-shaft outdoor faucets common on houses built after about 1990. They have a valve seat that lives 8 to 12 inches inside the wall, where the temperature stays above freezing. They are great when they are installed and maintained right and disasters when they are not.

Steps:

• Disconnect the hose and any splitter, timer, or back-flow attachment
• Leave the hose lying out, drained, or coil it after it empties (a hose left attached holds water against the valve seat and defeats the entire frost-free design)
• Open the faucet briefly to let any trapped water drain out
• Close the faucet

If your frost-free bib has a vacuum breaker (the small cap on top of the spigot), check that it is not damaged. A failed vacuum breaker can hold water inside the body of the faucet even after you disconnect the hose. Replacements are about $8 at any hardware store in Lancaster or Grove City.

On a Pickerington property in February 2024, the homeowner had a “frost-free” bib that burst because she had left a hose attached all winter. The frost-free design only works with the hose disconnected. Leaving the hose on traps water inside the long shaft of the bib, that water freezes, the copper shaft cracks, and you do not find out until the next time you turn the water on in April.

How do I winterize a standard hose bib?

Older homes, mostly pre-1990 builds in Bexley, Clintonville, Circleville’s historic district, and similar neighborhoods, often have standard (non-frost-free) hose bibs. These have the valve right at the outside wall and an inside shutoff valve somewhere in the basement or crawl space.

Steps:

• Find the inside shutoff valve for that bib (often on a copper line a few feet inside the wall)
• Close the inside shutoff completely
• Go outside, open the outdoor faucet, and let it drain fully
• Leave the outdoor faucet in the open position all winter so any residual water has room to expand if it freezes
• Some inside shutoffs have a small bleeder cap. Open it with a bucket underneath to drain the line back to the shutoff

If you cannot find the inside shutoff, that is worth knowing now in October rather than during a burst-pipe crisis in January. Trace the copper line from the outdoor bib back into the house. Sometimes the shutoff is hidden behind drywall, in a chase, or above a drop ceiling. If there is no shutoff at all, get one installed before winter. A plumber can usually do it in an hour.

How do I winterize an irrigation system?

Irrigation systems are the most expensive thing you will winterize and the most expensive thing to repair if you skip it. A failed backflow preventer alone runs $200 to $500 in parts plus labor. A cracked manifold can be $1,000-plus depending on access.

The right way to winterize an in-ground irrigation system is a compressed-air blowout, not just shutting off the water. Even with the water off, residual water in the lateral lines, valves, and heads will freeze and crack components.

Blowout procedure:

• Shut off the water supply to the system at the main valve
• Connect a 30 to 80 CFM compressor to the system’s blowout port
• Open each zone in sequence, one at a time, and run air through until the heads stop misting
• Move the backflow preventer’s ball valves to a 45-degree position to prevent ice damage to the seats
• Drain any aboveground components per the manufacturer

Most homeowners do not own an 80 CFM compressor. A pancake compressor from a garage workshop will not move enough air to clear a residential zone, and undersized compressors can actually damage heads by heating the air too much. This is a service call worth paying for.

We blow out residential irrigation systems across our service area as part of our fall cleanup service, typically bundled with the final mow and gutter cleaning. A typical 4 to 8 zone residential system runs $75 to $150 depending on the system. Quotes are written per property.

What about outdoor kitchens, pot fillers, and dishwashers?

Same idea, different fixtures. If you have an outdoor kitchen with a sink or a pot filler, the water lines feeding it need to be shut off at an interior shutoff and drained. If there is a refrigerator with a water line, the line needs to be shut off at the inside connection and disconnected from the appliance. Outdoor ice makers and dishwashers need to be drained per the manual.

On a Canal Winchester custom-build I worked on this fall, the homeowner had an outdoor kitchen with no shutoff inside the house. The line ran directly from the basement through the foundation to the kitchen. We added an inside shutoff this October before the first freeze. Cost of the addition: $180. Cost of doing nothing and dealing with a frozen line: probably four figures.

How do I winterize ponds, fountains, and water features?

Three options depending on the feature:

• Small fountain or birdbath: Drain completely, store the pump indoors, and either cover the basin or store the whole feature in a garage.
• Medium recirculating water feature: Drain the basin, remove and store the pump indoors, leave the feature open and allow snow and rain to drain through.
• Koi or goldfish pond: Different problem. The fish overwinter under the ice in most Central Ohio ponds, but you need a de-icer or aerator to keep a small opening in the ice for gas exchange. A frozen-over pond suffocates fish.

Ponds with fish are their own topic, and OSU Extension has good guidance on overwintering them. Get that work done by mid-November.

For homeowners who want to skip the whole question and have us run the checklist on the property, our residential service covers fall winterization on top of mowing and cleanup. One visit, one invoice.

What if I am leaving town for the winter?

Different rules. Snowbirds heading to Florida from October through April should shut the main water supply to the house off at the meter, drain the lines fully, and have someone check the property weekly. Heat tape on vulnerable interior pipes is cheap insurance.

If the house is occupied but cold (a vacation cabin or rental held empty), keep the heat set no lower than 55 degrees, open cabinet doors under sinks on exterior walls, and consider letting one interior faucet drip on the coldest nights. Moving water resists freezing.

Per Ohio EPA and Ohio Department of Commerce plumbing guidance, a single burst supply line can release 200 gallons of water per hour. A weekend away during a polar vortex can mean a flooded first floor.

What gets covered in a professional winterization visit?

When we do a full residential winterization, the visit usually includes:

• Disconnecting and storing hoses
• Closing and draining all hose bibs
• Blowing out the irrigation system if present
• Closing inside shutoffs and bleeding the lines
• Draining or covering water features
• Walk-around photo report of any concerns (cracked siding, foundation gaps, pest entry points)

Bundled with a final mow, gutter cleaning, and leaf cleanup, a typical residential property runs $250 to $450 depending on size and what features need attention. Written quote per property.
