Project

With all the new seals installed on the stem, it's time for reinstallation. Carefully guide the washer-end of the long stem back into the faucet body. Push it in gently and steadily until it is fully seated. You may need to gently rotate the stem to help it align properly with the inside of the faucet body. Push it all the way in until the threaded portion where the packing nut goes is exposed and in its correct position.

Frequently Asked Questions

What's the most common reason my frost-free outdoor faucet is dripping, and how does this repair fix it?

Most drips from frost-free outdoor faucets are caused by worn-out rubber washers or seals located on the long stem assembly inside. This project guides you through replacing these degraded components, which restores the watertight seal and stops the drip. You'll typically find these parts in a faucet repair kit.

I'm new to plumbing; how difficult is this project, and how long should I expect it to take?

This repair is rated as beginner-friendly, primarily requiring careful disassembly and reassembly. For most first-timers, it typically takes 1-2 hours to complete, assuming parts aren't excessively corroded. Patience and careful attention to the steps are more important than prior experience.

What are the most crucial tools or materials I should ensure I have before starting, especially if parts are stuck?

Beyond a screwdriver and adjustable wrench, ensure you have penetrating oil (like KROIL) on hand to loosen stubborn nuts or screws. A specific faucet repair kit for your faucet model is essential, as is plumber's grease or silicone grease (e.g., Super Lube) to lubricate new seals and threads during reassembly.

What is the most critical safety precaution I need to take before starting this repair?

The absolute most critical step is to shut off the main water supply to your house or the specific outdoor faucet line before you begin any disassembly. After shutting off the water, open the faucet to drain any remaining water pressure and prevent unexpected leaks or flooding during the repair process.
