Dealing with water pipes can prove difficult especially when temperatures are low. This is because water tends to change state from liquid to solid when it is exposed to certain temperatures.
Furthermore, when water freezes, it expands and this may not work well with your pipes. As a result, the pipes may bulge or burst in worst-case scenarios. Both situations will require you to spend money on repairs and replacements.
You can save yourself from all this by preventing the disaster before it occurs. By using a frost-free sillcock, you can stop water from freezing inside your pipes.
These plumbing items are specially designed to withstand harsh weather conditions like the one experienced during winter. Since the seat valve and the stem washer are kept in the house, the water will maintain its liquid state.
Also, these pieces of equipment ensure that your water is safe from contamination through the anti-siphon feature, which prevents water that has already been pumped from flowing back to the source. If you are worried that winter is coming, here are some of the best frost free sillcocks that can help you keep your pipes free of the freeze.
