804LF 4FT. SIMMONS HYDRANT | The Frostproof yard hydrant provides running water for lawn and garden, livestock and fire protection all year, even in sub-zero temperatures. The shut-off valve operates below the frost line. Hydrant cannot freeze because when it is closed, all water in the standpipe drains out a hole in the valve which is set in the ground below the frost line. Hydrant spout operates at a convenient height (24 in) from the ground level so that it can spill into a stock tank. Adapter (No 8828) is threaded for 3/4 in hose. Hydrant can be easily installed anywhere water is supplied under pressure. To prevent unauthorized use, handle can be padlocked by inserting padlock into holes provided in handle and head.
