Having a problem...took out old bathtub...bought new tub. Have gotten all outgoing plumbing taken care of leak free!! Starting on incoming plumbing. Had to cut hot and cold pipes to adjust height for the new tub. Soldered hot and cold pipes, also put shut off valves on them. Put the new mixing valve on to make sure water would go through and all I am getting is a trickle of hot water, but the cold water is fine...is there something that I am missing? New to this. Any suggestions would be appreciated. Thanks!
