Use this all brass shower head in conjuction with the High Output plastic or brass shower filters. The chrome plated brass shower head produces a feeling of a forceful flow of water, yet conserves water using less than 3 gpm. By the press of a button, you can adjust the flow from full on to full off. But don't leave it in the off position because the filter housings are not designed for use under pressure. This head is easily installed onto 1/2" pipe threads.
