Deck scuppers

[DCI75]

As a new owner of a 1996 Mako 181 Flats, my question is on deck scuppers. Both port and starboard drains go through PVC check vvls which seem to have failed. I've been advised to take them both out and put straight PVC in there and use Seachoice scuppers instead.

Any advice would be helpful.

Thanks!
