T&S Brass has two new thermostatic mixing valves – the EC-SMT and the EC-TMV. Both versions are made of solid brass, and feature check valves built into hot and cold inlets to prevent backflow and water contamination. Each are tested and certified to ASSE 1070 standards. The EC-SMT is designed for under-deck or concealed installations where the EC-TMV is for above-deck installations. Additionally, the EC-SMT has a chromed level-style handle and a vandal-resistant screw.
