I have the Symmons Temputrol shower valve. I replaced the spindle and the two seats last week and it seems now I have to spin the dial all the way till it stops to get a decent shower temp. After I run the water to take a shower and I spin the valve to he spot where I used to stop at it starts to get warm. About a minute or so in I always hear a sound, kind of like a pop and the pressure changes and it starts to get colder so I have to move the dial even farther to the hot side. Nothing is using water at the time this happens so I can’t tell what’s causing it. It’s gets hotter when I move it farther but it doesn’t seem to get as hot as it did before I replaced the spindle. It used to steam up the bathroom but don’t think it will now. When I assembled the valve I made sure the anti scald screw was backed all the way out so I would be able to get full hot water. I also just rebuilt my boiler burner but I don’t think that would matter. I don’t have a hot water tank the hot water is in the boiler. Do I need to turn up the auqastat.. I never messed with it before. Here’s a link to the auqastat and some mixer valve that on the hot water side. Wasn’t sure if I should put this in the boiler section or not. Thanks for any help!

Hoping someone can help. I replaced a roman tub valve in which the existing valve was supplied with 3/4 in pipes and the new one is 1/2 inch. I reduced the copper lines to use the new 1/2 valve and it seems as if the volume is too much and the new valve constantly leaks even when shut off. any ideas?
