Generally speaking, which is a better long term investment, a non-corrodable

prone to clogging.



There is no reason that PVC would be prone to
clogging, in fact, the smoother surface makes it
less likely to clog. PVC doesn't corrode, is
cheap, and easy to install. They only minus is
that the nuts sometimes split, but replacement is
generally simple and quick. Does metal have any
benefit over PVC? Maybe appearance when exposed.
