Remember, depending on your house water pressure, you are going to generate a LOT of waste water. You don't need larger that 1/4" tubing for the waste water. Try routing that along the baseboard to a drain. You may not be able to pipe it directly into your sump if it's not close enough to a drain. A lot of folks collect RO
water in a separate container with a float switch and dispense out of there into portable containers. You may not be able to get everything set up the way you planned.
