RE: Frost Plugs?
In some USA northern climates hydrants are provided with a small plug in the base. Thge plug is removed upon installation. After using a hydrant and the hydrant valve is closed, the water can slowly drain out through the hole. This prevents ice from forming during cold weather, which could expand and damage the hydrant. Sometimes referred to as "frostproof", that's how I made the connection to "frost plug".
