Darn, I just checked my boat and lo and behold I have white PVC 90 degree connectors outboard of the marelon seacocks under my head sink.
I also note in an earlier pic when I first got the boat there are grey connectors on the cockpit drain and maybe the sink drain, but they are less worrisome as they are inboard of the marelon seacock.
Also worrisome are the plastic thru hulls (not sure what material or make). Altough the setup has worked for nearly 38 years (and as someone who comes from the if it aint broke dont fix it school of thought, at least above the waterline) I will have to assess if these hull penetrating connections are living on borrowed time.
(Note: in that under galley sink pic the sea strainer is a dead soldier, one of the first things I replaced. I have had a prior history on a 1989 Pearson 39 I had for many years where one of the bolts holding the top on gave way (mostly in part due to my exuberant tightening after cleaning out the strainer). Were it not for an observant harbor master she would have gone down. Fortunately she suffered only 8" of water above the floor boards and no major damage. The insurance appraiser told me I would not have been covered anyway as that sheered bolt would have been considered a routine maintenance item. After tossing much of the hardly ever used gear that got wet and really cleaning the bilge the boat seemed to sail faster
