Frequently Asked Questions
Q."What is siliphos?" A. Siliphos is a water treatment compound; a glass-like Polyphosphate containing Sodium, Calcium Magnesium and Silicate, formulated specifically for the treatment of water problems and to prevent the build-up of scale in plumbing.
Q."What is CA AB 1953 and VT S.152 and how is this different from previous low-lead legislation?" A. The United States Environmental Protection Agency (EPA) regulates the amount of lead in drinking water under guidelines established in the Federal Safe Drinking Water Act (passed in 1974; amended in 1988 and 1996). This Act defines "lead-free" as not more than 8% lead in pipes and fixture fittings. PLEASE NOTE: Use of the term "lead-free" varies between the new legislation in CA (AB 1953) and VT (S.152), and in the current Federal Safe Drinking Water Act requirements. In the new legislation for CA and VT only, starting in 2010, it will mean 0.25% or less (weighted average).
Q."I received my Takagi tankless water heater recess box (Model TK-RB02) and it doesn't have any holes for the water, gas, or electric lines - so how do I connect the lines?" A.You need to drill holes in the TK-RB02 recess box to accommodate the gas, water, and electric lines. There are three suggested places to drill the holes; these are illustrated in the diagram below. For the side entry option, just drill two holes for the water on one side and one hole on the other side for the gas as pictured in the diagram. For the bottom entry option, just drill 3 holes in the bottom of the TK-RB02. There is also a back entry option where you drill 3 holes in through the back as shown in the diagram.
Q."Can I install this scale inhibitor upside down?" A.This scale inhibitor can be installed in any direction with the filter pointing in any direction as long as the water flow direction is correct and the system has suitable pressure to function properly. Please note, the manufacturer recommends that the filter be supported if the Venturi tee is not installed horizontally with the filter outlet pointing downward. Also, if the Venturi tee is not installed horizontally with the filter outlet pointing downward, it may be more difficult to catch the remaining water in the line when replacing the cartridge. As always, please consult with a trusted local professional if you are at all unsure about correctly installing this scale inhibitor.
