Yes! That is the plan, on one side anyway. I was able to replace one of the 2" Forespar 93 series valves with a 1.5" valve, but on the other side I can't disassemble the valve because of restricted space, So I will just use a short piece of the Headhunter and then a reducer and the saniflex. I am ordering new Ronco tanks with 1.5" discharge. The original tanks are aluminum (!) and and showing signs of corrosion.An off-the-wall idea that may or may not be a good one, but worth considering to save at least $10/ft:
1.5"-2" reducing adapters at or near each end to let you use 1.5" hose. Raritan SaniFlex RaritanSaniFlex hose is the top rated hose...has proven to be 100% odor permeation resistant and is also so flexible it can be bent like a hairpin without kinking...making re-hosing jobs a LOT easier! Fisheries has it.
Will 1.5 hose fit your deck pumpout fitting, or will you have to use a reducing adapters that end?I am ordering new Ronco tanks with 1.5" discharge.
The deck fittings are 2” Amiot, which I will replace with 1.5” Amiot. The hole cutout dimensions (and screw hole I think) are the same. You book has been very helpful! But I have some (more) non standard things going on, so I’ll send you that PM to see what you think about what I’m trying to do...Will 1.5 hose fit your deck pumpout fitting, or will you have to use a reducing adapters that end?
If you have enough clearance above the tops of the new tanks, specify all the fittings on the top of the tank, with a pickup tube (aka "diptube") inside the tank on the discharge...Ronco will supply the dip tube assembly. If you plan to have the ability to dump tanks, TWO discharge fittings--both in the top of the tank--will eliminate the need for a y-valve.
If you'd like discuss fittings locations and sizes, send me a PM...I'll be glad to brainstorm it with you.
