Quick Answer
During cold winter months, frost-free hydrants require adjustments to their drainage systems to prevent freezing, which includes draining and blowing out the lines, inspecting and replacing worn-out parts, and installing winterization kits.
Preparing for Winter
To prepare your frost-free hydrants for winter, inspect the drainage system and identify any areas prone to freezing. Typically, this involves inspecting the hydrant’s drain valve, drain line, and winterization kit. Ensure that the drain valve is functioning correctly and that the drain line is clear of debris and ice. If your hydrant has a frost-proof drain, inspect the drain tube and replace it if it’s damaged or clogged.
De-icing and Drainage
Once you’ve identified any issues with your hydrant’s drainage system, you can begin de-icing the lines. Start by draining the lines completely using a hose or air compressor. This process typically requires 10-15 minutes to ensure all air is removed from the lines. Next, use a winterization kit to blow out any remaining water from the lines. These kits typically include a compressor and specialized nozzles that can remove water and debris from the lines.
Winterization Kit Installation
If you live in an area with extremely cold winters, consider installing a winterization kit specifically designed for frost-free hydrants. These kits typically include a frost-proof drain, a drain valve, and a winterization nozzle. When installing a winterization kit, follow the manufacturer’s instructions and take note of the recommended installation procedures. Typically, this involves installing the frost-proof drain in the hydrant’s pipe and connecting it to the drain valve. The winterization nozzle is then attached to the drain valve and connected to a compressor or air tank.
