We need to know where we can purchase a twin flush valve for an up flush toilet model U-P with automatic twin flush valve. This was purchased 6-3-85 from McPherson,Inc, in Tampa, FL, when we called the phone number it is no longer in service. Is there by any chance some place in MT that we can purchase this or eastern WA?
McPherson went out of business shortly after the 1.6 gpf became a requirement. I’ve searched for two years trying to find parts for my twin flush valve with no success. I have a twin flush valve you can have. It has a slight leak in one of the internal diaphragms and allows additional water to leak into the bowl, about 1 gal. in 24 hrs. Way short of overflowing. That problem can be avoided by putting a shutoff valve on the water supply line, either a quarter turn 1/2″ ball valve or a full flow solenoid valve. I used a solenoid valve, 12vac with a timer relay set at 10 min. and put the switch right next to the twin flush valve actuator. I have since gone with a Myer’s Sewage Pumping package with an American Std. 1.6 gpf toilet and I am very satisfied.
