Did you solder the valve in? If so you may have got it to hot. Or debris could have gotten in the valve. Turn the water off, remove the handle and cartridge. Check cartridge for damage or debris

Yes, I believe this unit uses a cartridge right? They do fit a little tight due to the small washers on the back side of the cartridge. If this is the one I'm thinking of, there are two leg like appendenges that come off the back and fit into small holes at the back of the manifold or what some call mixing valve housing.

Look at the ring nut right below the #1 in this pic.
Your's should be similar to this one.
