Servicing The Z-one™ Valve Body

One of the best features of Caleffi's Z-one™ valves is complete serviceability through the bottom port of the valve body. You can even service a 2-way valve without removing it from the piping. Bob "Hot Rod" Rohr shows you how easy and quick it is to clean and/or replace the internal plug/stem assembly to make your Z-one valve as good as new.
