I Ignored a Dripping Outdoor Faucet All Winter — Then Found the Pipe Split in Spring

The Fix and Prevention

The split section has to come out. I replaced mine with a 12-inch length of ½-inch Type M copper pipe and two sweat couplings — about $15 at Home Depot, plus $8 for flux and solder if you don’t already have them.

Cutting out the damaged section means opening the wall enough to get a tubing cutter in there. I used a 4-inch hole saw to go through the drywall, which gave me room to work. Clean up the cut ends with emery cloth or a deburring tool so the couplings seat properly, flux both the pipe and the inside of the fitting, then heat the joint with a propane torch until the solder flows in.

If you’re not confident soldering copper, PEX is more forgiving. You’ll need a crimping tool (around $30 to rent at Home Depot, $50 to buy), the pipe itself, and stainless crimp rings. SharkBite push-fit couplings are another option — about $12 each — and they need no tools at all, though some codes don’t allow them inside walls. Total for a PEX repair: $30 to $80 depending on what you already have on hand.

A plumber will charge $200 to $400 for the repair, depending on access and local rates. If the pipe is buried in a finished wall or runs through a tight crawlspace, expect the higher end.

But here’s what actually prevents it from happening again: swap that standard hose bib for a frost-proof sillcock. These run $25 to $60 at Lowe’s or Ace Hardware, and the valve seat sits 6 to 12 inches inside the warm wall, so freezing air never reaches standing water.

The key is that the washer and valve seat — the parts that actually stop the flow — are deep inside the house where the temperature stays above freezing. The pipe that extends outside is just a long stem with nothing to trap water. When you shut it off, the water drains out through a small weep hole near the faucet threads.

I installed a Prier P-164 frost-free sillcock ($38 at Lowe’s) with a 12-inch stem and added a quarter-turn ball valve indoors so I can still isolate the line if I need to. The whole job took two hours, including patching the wall.

And every October now, I shut off that interior valve and open the outside faucet to drain the line completely. That’s it. Even if the sillcock develops a drip, the indoor shutoff keeps water from migrating into the cold section.

The pipe has been dry every winter since. No drips, no splits, no surprise geysers in March.
