Sanitation Hoses - Which One?

[solecollector]

I am going to replace all the sanitation hoses on the boat as I'm having issues with the "big" ones leaking (the ones that go from the holding tank out) are starting to have little dimples on it - some rust spots are coming through as well.

What do you think about Raritan SaniFlex for the larger ones and Shields or Trident for the smaller ones?

Lastly, I have three heads. One is fresh (the newest one) and two are salt. We are going to replace another salt with a fresh... anyone have thoughts on keeping one salt just in case we are on fresh water crisis? Or does this defeat the purpose of fresh water heads...? We have a new water maker coming in soon and about 270 gallons of tankage. All thoughts welcome - !_steve

Look at this recent thread about hoses: http://www.cruisersforum.com/forums/...se-127971.html

I use a somewhat "unorthodox" solution... Standard schedule 40 PVC pipe of the appropriate id. All my msd waste connections are run in 1-1/2 inch pvc at around $0.50/ft. Fittings (sweeps, angles, tees, etc) run about $1.50 ea.

Use a 4" piece of sanitary flex where ever I have to transition to a barbed hose fitting (eg: head discharge, deck fitting, thru hull. Cheap, easy, and best is PVC pipe is impervious to waste odors unlike even the best "marine" sanitary hose.

Water and vent lines are run in 3/4 inch pex with copper crimp rings.

Total time to install new Type III MSD on Solitaire 45min including new deck fittings for pump out and vent.. Total cost including deck fittings < $50.00
