Our TA-10 flow-control spindles are designed for years of trouble-free service. To have two fail in such a short period of time is unusual, and could be due to water quality issues on site. My suggestion at this juncture is to submerge the stuck spindle in a bath of simple household vinegar for thirty minutes to dissolve any particulates that may have built up on the metal surfaces, followed by a couple of sharp taps to the bottom of the spindle on a block of wood. if this frees the inner piston, you should be all set. If not, you can contact Symmons customer service at 800-796-6667, let them know you've performed the required maintenance, and that you need a replacement TA-10 under warranty.
