Best way to join 2 differing size outlets to a single seacock and t into a sink drain

[davethedog]

Hello all, and a couple of questions:

Started the watermaker install and currently planning to join 2 of the current seacock outlets together (likely the galley sink discharge and the aft cabin head sink discharge) therefore freeing up a dedicated inlet for the watermaker. The current outlets are differing sizes (I think) and therefore will need to be somehow joined together at the stopcock. What is the best way to achieve this please?

Secondly, want to avoid drilling a brine discharge hole and so want to tee this into the galley discharge (above water level), any advice ref this?

Cheers

DTD

Use hose reducers to connect your pipes to your sizes some thought process and away you go :encouragement:

I user one of there

With one of there screwed into the above tee giving you a tee with different size inlets.

You could also use one of these a reducing tee
