<y house is only a year old and the shower in our main bath hasn't been used as we didn't have shower doors set up until a couple of days ago. I used the shower once over the summer and it worked fine, when I went to use it yesterday it only had cold. It is a moen with one handel, to get water you pull the handel out and then turn left for hot water and right for cold, when I turn left I get cold and right the water shots off. Any ideas what my problem is and what I need to do to fix it?
