just wondering if the UFH is creating some back pressure and the rad locksheilds are closed down too much so when the pump kicks in its pumping against too much resistance.

@adamk not sure I want to mess with the lockshields I assume that would mess with the balancing. 

have someone coming next Wednesday to take a look at all the issues.
