FOR A LOT OF REASONS!! The mechanical strength of elbows, Ts, Ys and other PVC fittings is the weak link in a PVC pipe system. This was discussed in numerous posts in the Cruiser's forum especially by Sailor Girl, a technical poster at that web site.

Next an electrical sweep has a larger bend radius that lessens flow resistance around corners. Further the sweeps are made with grade 40 PVC which has high mechanical strength.

But hey--- do as you wish, maybe in your case you should stick with hoses.
