I use a mag18 to move the water from my basement mixing station up to the DT on the 1st floor, so probably 10' up, and a horizontal run of about 20'. I used 3/4" pvc to plumb it. The flow is adequate, but when the mag18 dies I'll replace it with a mag24. IMHO, the mag drives are great for water transport, but as I have found by leaving it on all night, they generate a huge amount of heat. Not necessarily a bad thing if your water is in the garage?
And FWIW - I use a $10 remote power switch I got from Menards to turn the pump on/off. Best $10 I ever spent.
