Obviously copper piping would be a no-no, so if i use pvc piping, do i use the standard plumbing grade cement? I plan on putting a sump in the basement and coming up thru the floor to the tank using a high head pump.

correct
I suggest using the cleaner fluid also

also remember
when the power is off
the pipes will drain
so you will need a large volume sump

we haven't found a brand of check valve we trust
(I think the salt eats the rubber)
I would say skip the check valve and over size the sump...
there is a formula somewhere for gallons per foot of various size pvc pipe
(volume of a cylinder?)

I won't even pretend to know the answer, but here is something I found that may help..........


The volume of a circular cylinder of height h and radius r is

pi x r 2 x h
If you stand your hose on end you have a circular cylinder of height 500 feet and radius of one-half of 3/4 inches which is 3/8 inches. We need to settle on the units to use so let's use feet. Thus the cylinder has a radius of 3/8x12 = 3/96 = 1/32 inches.

Hence the volume of the hose is

pi x r 2 x h = 3.1416 x ( 1/32) 2 x 500 = 1.534 cubic feet
