Benefits of 2-pipe vs single
For an in basement tank with a Becket AF roughly even with the bottom of the tank and 8ft from it with overhead lines running 8.5ft from the basement floor, what are the advantages and disadvantages of a 2 pipe vs a single pipe. I know the 2-pipe has a greater flow through the filter (which I don't think is a bad thing) and the 2-pipe is self priming but other than that I'm just curious.
