Hello

The tap in my bathtub is a single lever control. The other day it would only turn not quite half way. I am not sure what happened but it almost seems like there is something stuck. Any clue what could have caused this and how it can be fixed.

Brand/model would help. Some control valves use plastic gears that form a antiscald feature, this feature can break.

It is a Delta. From looking on the internet I think the model is the Classic Monitor Scald-Guard Tub & Shower Trim. Also from looking on the internet I found directions on how to adjust the hot water control/check if it is broken.

Thanks

Open up the valve and check the "limit stop". (See image) Let me know if that's it. Good luck, Tom

Thanks

It was the limit stop that needed to be ajdusted.
