After replacing a TA-10 cartridge, the hot water temp fluctuates from luke warm, a brief spot of cold and maybe hot few seconds. Mostly just luke warm. Also I can spin the valve a full revolution and a 1/4 more. Not sure why I get the 1/4 more turn. The stem and cap was screwed completely. I get hot from all sinks. Just installed new tank and set to 150. Tank was changed because of another unrelated problem. This problem was with old tank too. I've rebuilt the old cartridge and haven't tried it yet. I can also shake it and can hear it rattle.
