PVC doesn't just break on a whim any time. When installed so it's not a
stuctural member and not subject to bending, chafe, or heat above 140F.,
it will last forever (ie. longer than you need to worry about).

In marine installations, a normal precaution would be flexible hose
connections where the pipe might otherwise be moved regularly. It must
be strapped rigid so that when the boat pounds the pipe doesn't move;
that means at least every 4' for 2" pipe, more for smaller diameters.

What ever you do, don't us PVC pipe if rerouting. I bought a boat this
spring and the guy had rerouted the scuppers inside the fly bridge deck. He
was a sharp cookie and didn't realize water didn't run up hill. Need less to
say the PVC broke and caused water damage in the cabin. The only permanent
solution I have come up with is install a stainless steel pipe or pillar to
run the water down.

I tired of drip marks and stains down the hull topsides from scuppers.
I want to get a solution before I have the boat LP'd.

It seems that I either need to fill in the scuppers and put in
thru-deck scuppers that drain down to thru hulls in the bootstripe -
or put some kind of drip tube or drip lip - either permanent or
removable - into the existing scuppers so that drips would drop far
enough out from the boat to miss the topsides.

I'm concerned that permanent stiff ones like s/s tubes or whatever
might scrape people or poke inflatables while trying to board. Maybe
something flexible like clear silicone rubber sheets or tubes?

Seen any good ideas?
