Is it ok to reduce the size of the pipe going to a large expansion tank? Mine is a extrol SX-90 and I reduced the pipe size from 1-1/4 coming out of the tank to 1" and then to 1/2". My primary loop is 1" but I wanted to connect the tank to the pressure reducing valve and air bleeder which were only 1/2". Anyone see this as a problem and if so, what lind of problems could result?
