I'm having a well drilled 750' deep; my pump is a 3 HP, 10 gpm submersible unit. I think I need to use galvanized steel pipe rather than PVC because of the depth and weight of the water. I've figured 35 joints of 1-1/4" steel pipe; but I don't know what schedule the pipe should be. Once I know...

If my drain pipe is 1 1/2 do I stay with that for the new drain or is there any benefit or problem with using a 2" drain?

I need to run some plumbing for a basement kitchen, laundry room, and an upstairs 1/2 bathroom. There is a 1/2" line to the area already. Do I need to change it to a 3/4" line? Will it be worth the cost to change it?
