Currently my piping is all 1.5". I purchased Hayward Aqr15 and zinc anode 104d that both require 2" plumbing. My plan is to couple 1.5" to 2" after the filter and before my return splits. This distance is about 5.5' with 2 90 degree elbows. I will then plumb the cell, flow switch, and anode into the 5.5' of 2" pvc making sure the flow switch has 12" straight run upstream. Will the roughly 5.5' of 2" piping be ok considering everything else is 1.5"? My plumbing order from the filter I was thinking is anode, cell, switch.
