Why your outdoor spigot is prone to freezing and how to fix it

How to Replace a Spigot | Ask This Old House · 7:21 · Video: This Old House · Watch at the source

In short: A leaking hose spigot usually fails at the bonnet or the stem. To prevent winter damage, you might need a frostproof model. This version uses a longer stem that reaches inside your home, keeping the washer away from freezing temperatures and protecting your pipes from bursting.

When an outdoor spigot fails, the leak typically originates from one of two specific points: the bonnet or the stem. For a permanent solution, plumbing expert Richard Trethewey suggests replacing the unit entirely. This process begins by shutting off the water supply and locating the specific line feeding the spigot. Once the line is identified, you must cut the pipe in an accessible location, using a bucket to catch any residual water that escapes during the process. Richard Trethewey, a specialist in plumbing and heating, provides these professional insights. This expert guidance helps homeowners extend the lifespan of their existing hardware.

Precision is vital during the replacement. You must measure the new pipe connection to ensure it matches the original dimensions. If the fit is not a concern, you can use a threaded adapter and Teflon tape to extend the pipe. Alternatively, you can solder the pipe directly into a frost-free faucet connector. However, if you choose the soldering method, you must first remove the inside stem to prevent the rubber washer from melting under the heat. This method ensures the new setup is identical to the previous one. Careful preparation is essential to avoid damaging sensitive components during the repair.

The final installation involves sliding the new spigot into position and soldering the connection with a coupling fitting. To ensure the fixture remains secure and resists corrosion, use stainless steel screws, which are less likely to rust over time. Once the hardware is installed, turn the water supply back on to test all connections for leaks. All necessary tools and materials for these repairs are standard items found at home centers or plumbing supply stores. Testing the system confirms the integrity of your work. These essential supplies are readily available at local hardware shops.
