OK, so I should stick with the same size pump.
Not sure I understand the balancing suggestion. My bypass consists of a 15mm gatevalve taken off the 22mm flow between the pump and diverter. There's no valve in the flow to coil, apart from diverter, to reduce/control flow.
oilman, I can feel a new thread coming on, as the pump upgrade question has been answered and we're now talking about balancing things. You obviously knew where we'd end up. I'll start a new topic for the power flush question.
