Topic: Plumbing the side deck scuppers

Hello Everyone,

My 1971 Contessa has a bronze 1 1/2" (i.d.) thru-hull fitting on the transom.  This was plumbed to the side deck scupper drains with a (home and garden) tee, some reducers and two 3/4" (i.d.) hoses.  The side deck scupper drains are original and are a short section of copper plumbing pipe that was glassed in and flush with the deck. 

Does anyone know how to get these drains plumbed out correctly?  I'm having a hard time finding the fittings that seem like they would work well for this job.

Thanks,

Brian

I should have also said that the outside diameter of the plastic tee you see pictured is different than the outside diameter of the copper pipe which is causing a problem getting a section of hose to fit properly on both.  This is problem that started this project.

Re: Plumbing the side deck scuppers

I went ahead and bought a pair of marelon 1 1/4" flush deck drains to mount on the deck.  Now all I need are the fittings to get these two 1 1/4" hoses connected to the 1 1/2" through-hull fitting on the transom (see photo).  West Marine sells a 1 1/2" nylon tee but I can't find a couple of adapters that would thread into the tee and have a 1 1/4" hose barb on the other end. 
I did finally find these type of fittings at the local Lowes (gray plastic fitting in photo) but the 1 1/4" hose barb on these measures 1 inch and 404 thousandths!!
This has been a very frustrating project because what should have been an easy task has been made next to impossible by not being able to find the plumbing fittings I need.
Has anyone else figured out how to plumb out their side deck drains?
Thanks,  Brian

Here's the other photo showing the difference in size between a marine grade marelon 1 1/4" plumbing fitting that measures 1250 thousandths and a Lowes 1 1/4" landscaping fitting that measures 1404 thousandths.
