Freeze Miser tap freeze protector

Description

A small valve that keeps an outdoor tap, or a hose feeding a trough, from freezing. It senses the temperature of the water inside it and lets a drip run once that water drops below 3 °C, adjusting the drip as the temperature changes.

Hand-tighten it onto the tap, then open the tap fully: it needs at least 10 psi (0.7 bar) of water pressure. It can sit level or upright, and upright, the brass end goes at the bottom. On a hose, keep it off the ground. It protects up to about 46 m (150 ft) of hose above ground.

Its thread is ¾ in garden-hose thread (GHT), which doesn't screw straight onto a ¾ in BSP tap, so you'll need an adaptor.

It protects only the tap or hose it's fitted to, and it drips in frost, so the water needs somewhere to go. At the end of winter, take it off, let it dry and store it indoors.
