Shutting Off the Water Supply
Before replacing the PEX hose bib, it’s crucial to shut off the water supply to prevent any water damage. Follow these precise steps to ensure safety:
1. Locate the Water Main Valve
Typically, the water main valve is located in the basement, garage, or crawl space. It’s usually a large, round valve with a handle. If you can’t find the water main valve, consult with a licensed plumber.
2. Shut Off the Water Supply to the Hose Bib
Once you’ve located the water main valve, it’s important to shut off the water supply specifically to the hose bib. This requires locating the shut-off valve for the hose bib, which is usually located near the hose bib itself. In most cases, it’s a small valve with a handle or a lever. However, if you encounter a PEX hose bib without a dedicated shut-off valve, you’ll need to turn off the water supply to the entire house. To do this, follow these additional steps:
- Identify the Water Distribution System: Determine whether your house uses a PEX or copper pipe water distribution system. Identifying the material will help you locate the correct shut-off valve.
- Find the Manifold: Locate the water distribution manifold, usually found in the basement, garage, or crawl space. This central point connects pipes to various fixtures and appliances.
- Locate the Hose Bib Line: Identify the specific line that supplies water to the hose bib. If your house has a PEX pipe system, look for a color-coded pipe (typically blue) or a label indicating the hose bib.
- Turn Off the Manifold Valve: Locate and turn off the valve on the manifold that corresponds to the hose bib supply line. This will isolate the water supply to the hose bib.
3. Check if the Water Supply is Off
Once you’ve turned off the water supply, open the hose bib to release any remaining water in the line. If no water flows out, you know that the water supply has been successfully shut off.
Locating the PEX Hose Bib
Finding the PEX hose bib outside your home is crucial before you start the replacement process. Here’s a detailed guide to help you locate it:
- Check the Exterior Walls: Walk around the perimeter of your house and look for a small, round or oval-shaped knob protruding from the exterior wall. This is typically where the hose bib is located.
- Follow the Water Supply Lines: Trace the water supply lines that run along the outside of your house. The hose bib will often be connected to one of these lines.
- Inspect the Foundation or Crawl Space: In some cases, the hose bib may be hidden beneath the foundation or inside a crawl space. Look for a pipe stub-out or a small hole in the foundation where the hose bib could be connected.
Tips for Finding the PEX Hose Bib
| Situation | Tip |
|---|---|
| Underground Hose Bib | Check for a small access panel or lid in the ground near the location where you expect the hose bib to be. |
| Behind Obstacles | Remove any plants, shrubs, or other objects that may be blocking your view of the hose bib. |
| Frozen Hose Bib | If the hose bib is frozen, gently thaw it using warm water or a hair dryer. Never use open flames or sharp objects. |
Disconnecting the Old Hose Bib
1. **Turn off the water supply.** Locate the main water shut-off valve and turn it off clockwise. This will prevent water from flowing into the hose bib while you are working on it.
2. **Open the hose bib fully.** This will release any residual water pressure in the line.
3. **Disconnect the hose.** If there is a hose attached to the hose bib, remove it by pulling it straight off.
4. **Disconnect the hose bib from the supply line.** Depending on the type of hose bib, there are two common methods for disconnecting it:
