nw pa | I vote for option two.. since this is a five into a four there is a chance of to much pressure on the four and a blowout.. considering that most water will flow to the four inch anyway .. tying the fives together will allow extra space for water.. Not knowing how much water will flow through each pipe ,the concern is that both are towards the end of the tile ,therefore with the most water running,and should the four inch not handle the flow it will back up and drain through the five inch. | |
