Hello Peggie, I re-plummed my head intake hose by connecting it to the head sink drain hose with a 'T' fitting. I spliced it in about half way between the seacock and the sink. What I do notice is, since the seacock is below the water line, there always seems to be some sea water left in the hose after the seacock is opened to use the sink. The result is an odor generated from the stagnant sea water after left for a week. Also some of it finds its way to the toilet during the 'fresh water' flush, so the first flush after unused all week causes an odor in the toilet. Would the solution be to move where the 'T' fitting connects to the drain hose?? Would it have been better to intall the 'T' either right under the sink, of just above the seacock?? Thanks for your help. Roc
