Larger suction pipe to pump - better?
All inside tubes, inlets on the pump, and suction tube from fresh tank are 1/2". 3GPM pump, 40 PSI on the push side, self-priming up to 10ft (I think). Now, imagine fresh tank 6ft away, sitting on...

Ok, so 3/4 will be the same or not much better than 1/2.
Another question: will it make any difference to the pump if the intake tube is 1) up-lift tube inside from the bottom of the aux tank, through the opening near top of the tank, then 3ft down to the ground, then 5ft up to the faucet (let's ignore shower for now),
or 2) from another opening near bottom of the aux tank, few inches to the ground - and then again 5ft up to the faucet.
#1 adds one more 90-bend, this should add more friction - but I have a feeling that pump won't even notice this.
