Size of hoses

[Tom23254]

I made a list of what size hoses and lengths I need and than left it on the boat 450 miles away. If anyone can tell me what is the inside diameter of the waste hoses coming off the electric heads maserator and going to the holding tank is I would be grateful. Also I need the inside diameter of the hoses coming from the lake and going to the heads. If you have a 1990- 1995 42 Hunter and could take a look it would save me much time. Thanks Tom

All toilet intake hoses are 3/4 ID...

If your toilet is a Jabsco the discharge is likely to be 1"...but COULD be 1.5" if the PO replaced the discharge fitting. Jabsco is the ONLY mfr to use 1" discharge for toilets and tank discharge macerator pump...every other toilet mfr uses a 1.5" discharge. And your tank inlet fitting is certain to be 1.5", 'cuz that's the industry standard. Macerator pumps are 1.5" in, 1" out.So I suggest you go with 1.5"...worse case you'd only have to replace the toilet discharge fitting or install a 1" x 1.5" adapter. In fact, if the toilet IS a Jabsco that has a 1" discharge, there's prob'ly already an adapter in the line.
