A while ago an expansion tank was added to our hot water tank and since then we have lost almost all water flow to just our shower. I CAN'T TAKE IT ANYMORE!!! The kitchen sink and bathroom sink are fine, its just the shower that has the problem....what can we do to fix it? I've already checked the shower head to be sure it wasn't clogged. Also the water is leaving an orange film on the shower walls, is this just mildew?
Do you have a water softner? Most often brown or orange stains are from iron in the water.
Very often when pipes get worked on trash gets knocked loose in the lines, my guess if the antiscald valve is sticking in the control valve?
