Richard explains the best ways to prevent frozen and burst pipes during the winter months.

Shopping List for How to Prevent Frozen and Burst Pipes:
- Foam insulation (size will vary based on pipe size)
- Pipe heating cable
- Cable ties

Tools List for How to Prevent Frozen and Burst Pipes:
- Utility knife, for cutting foam insulation

Steps for How to Prevent Frozen and Burst Pipes:
1. To keep water from freezing on an outdoor spigot during the winter, shut off the water valve to the outdoor spigot.
2. Drain excess water from the pipe.
3. To prevent indoor pipes from freezing, cover exposed pipes with foam insulation. It comes in long strips and can be cut down to size with a utility knife.
4. Use cable ties to tie down pipe heating cable for any pipes that may need extra heat to stay fluid.
5. If pipes under a sink are on an outdoor-facing wall, open up the cabinet doors to let heat from the house flow underneath the sink.
6. On extremely cold days, leave at least one sink on a slow drip to keep water moving in the pipes.

Richard demonstrated foam pipe insulation, which can be found at any home center.

He also used AHB electrical freeze prevention cable from Emerson Industrial [https://bit.ly/3enPj6m]
