    Shower is Hot or cold, no warm, low pressure!
    My shower is weird. It is a single handle knob with the little pin that pulls up out of the bath faucet to turn on the shower. The bath water is fine... High pressure, super hot or cold and everything in between. However, when I put on the shower there is an initial burst of water and then low pressure continuously. It is not unusable but it is weak. The weird part is that the water will only go super cold or super hot and it will not get warm. If I put the handle in the middle it is ice for the shower but if I switch back to the tub the water is nice and warm. I have changed the shower head and I have a new water heater.

    My theory is that there is an obstruction right where the pipe goes up to the shower that is preventing cold and hot water from mixing and weakening the pressure. Does anyone know how to flush the shower part of those pipes without knocking out my tile? Or better yet, you can tell me what is really going on and give me an easy solution. Thanks to anyone with enough free time to answer this question.

    I have a similar problem, but not quite as extreme. This all happened after I replaced the hot water heater. Did you ever find a solution?
