New Freeze Proof Hose Bib! #plumbing #plumber #diy

What happens here

In a standard hydrant, if a hose is left connected, water can back up into the pipe. When temperatures drop and this trapped water freezes, it expands. This expansion can lead to the pipe bursting, causing significant damage and potentially costly repairs.

Goal: Recognize the risk of freezing pipes with standard hydrants.

Tools and materials

  • Garden Hose — The attachment that can cause water to back up into a standard hydrant
  • Standard Hydrant — Illustrating the problem of pipe bursts

So, in a standard hydrant, what will happen if you keep the hose on, water will back up, water expands, and will actually burst the pipe. What we've come up with through the vent cap, if you leave the hose on, inside here there's a freeze plug. So, as the water freezes through the hose, it will actually pop the plug, keeping the barrel safe. And all you need to do in the spring once once the thaw comes, is just replace
