    I have a Moen Single Handle Shower ( Posi temp version ) and it's only trickling water in the cold position. Once you get it to about 12 o' clock it comes on full hot with no in between. It's only 1 1/2 years old. Does the stem need replacing? I also see 2 adjustment screws on either side of the valve in the wall. What are they for? Thanks.......

    Are you sure it is a "positemp?" Correct me if I'm wrong, The only valve that I know that has the 2 "screws" on iether side (shut off valves/stops), is the moentrol.

    If it is a moentrol, you will need a balancing spool
