Larger pre-pump hose?
I remember reading about a certain install that Aquamist had to use bigger tubing from the tank to the pump. The local home center has up to 10mm tubing, and was looking at using it for a surge tank to big tank because of gravity, and there are even fittings for the pump threads. I was wondering if a larger pre-pump hose would reduce stress on the pump and give it a longer life.
