What you’re looking atAn outdoor faucet and irrigation supply

  1. Frost-free sillcock

    Its valve sits inside the heated basement at the end of a long stem, so the outside part drains and can’t freeze, as long as the hose is off.

  2. Long stem through the wall

    Slopes slightly to the outside so water drains out after each use. Coon Rapids requires self-draining, frost-proof hose bibs.

  3. Inside shutoff

    An interior valve for the outdoor line. Older homes may still have plain hose bibs that have to be shut off and drained from inside each fall.

  4. Hose left on

    Leave a hose attached over winter and the water trapped in the stem can freeze and split it inside the wall.

  5. Backflow preventer

    Lawn irrigation needs backflow protection, often a pressure vacuum breaker, tested by a certified tester when installed and every year after.

  6. Irrigation supply

    Buried supply to the sprinkler zones. EPA says an irrigation leak just 1/32 inch across can waste about 6,300 gallons a month.

01The short answer

Outdoor water, without the spring flood.

In one paragraph

In Minnesota, outdoor plumbing has one job in winter: stay dry. Frost-free hose bibs keep the valve inside, but only if the hose comes off. Irrigation needs its backflow assembly tested every year, a rain sensor by state law, and a spring check for freeze damage before the first run.

The outdoor failure we see most is a frozen hose bib that split inside the wall and leaks into the basement the first time it’s turned on in spring. Next is irrigation: freeze-damaged backflow assemblies and leaking lines.

Fall checklist

  • Disconnect hoses from every outdoor faucet
  • Shut off and drain any older, non-frost-free hose bibs from the inside valve
  • Have the irrigation system blown out and the backflow assembly protected
  • Make sure outdoor faucets don’t drip after you close them

Spring checklist

  • Check in-ground irrigation for frost or freeze damage before using it, as EPA advises
  • Turn on each outdoor faucet and look inside the basement for leaks
  • Schedule the annual backflow test

03Repair or replace

Repair the valve, or replace the bib?

Repair it if

  • It’s a frost-free bib with a worn washer or seat
  • The leak is at the packing nut
  • It drains properly after use

Replace it if

  • It froze and split inside the wall
  • It’s an old non-frost-free bib
  • It has no built-in backflow preventer, which Coon Rapids requires

I had a leaking outside faucet that had haunted me for two years. Last night it was making a loud noise. I was afraid that the water pipes would burst.

  • “Denis was great. Had him out to patch a ruptured exterior pipe/hose outlet. Good communication leading up and arrived when he said he would. Clear about what he would do/why, and just as importantly what he didn’t think was necessary. I would definitely use AP again.”

  • “Denis did our hose bibs on the recommendation of a neighbor a while back. … His work was clean and used higher end valves and fittings. So when we need a water heater he was the first call.”

06Questions

Outdoor plumbing questions, answered.

Straight answers, with the source when a rule or number is involved. Still not sure? Call and describe it.

Q

What is a frost-free hose bib?

A frost-free hose bib, or sillcock, puts its shutoff valve inside the heated house at the end of a long stem. When you close it, the water in the stem drains out the spout, so nothing is left in the cold part of the wall to freeze, as long as no hose is attached.

Q

Do I need to shut off my outdoor faucets for winter in Minnesota?

Disconnect every hose before the first freeze. Frost-free hose bibs don’t need to be shut off inside, but older, non-frost-free bibs should be shut off at their inside valve and drained. A hose left attached can trap water and split even a frost-free bib.

Q

Does my lawn sprinkler system need a backflow preventer?

Yes. Minnesota code requires lawn irrigation to be protected by a backflow assembly such as a pressure vacuum breaker, or a reduced-pressure assembly if the system injects fertilizer or chemicals. Coon Rapids typically requires a PVB, tested every year.

Source: 2020 Minnesota Plumbing Code §603.5.6; City of Coon Rapids

Q

Who can test a backflow preventer?

Testable backflow assemblies must be tested by a certified backflow assembly tester when installed, repaired or relocated, and at least once a year. Each assembly carries a dated, signed test tag, and the local code authority must be notified before one is installed.

Source: Minnesota Rules 4714.0603

Q

Are there lawn watering restrictions in Coon Rapids?

Yes. Coon Rapids typically runs an odd/even sprinkling ban from June 1 to August 31 based on house number, and its 2026 drought measures limited sprinkling to 4–9 a.m. Neighboring cities run their own odd/even schedules.
