Long story short.. I'm perplexed why trident marine's premium sanitation hose is offered in 1.875" ID, while nipples from groco and the like are offered in 1.5", 1.75" or 2". Why didn't they make that hose a squige smaller or larger...?
I called trident and talked with a couple of their guys. They couldn't give me a good answer except that 'this is what people want'.
So I ask how you guys make this work
, because I know I'm not reinventing the wheel
Long story long.. I'm wrapping up a gravity fed holding tank
install. I've already got the 1.5" through hull/flange/ball valve assembly. I have one of groco's regular nipples for 1.5" hose. The ID of the nipple is 1.25" and I'd like to increase that if possible. Groco offers 'full flow' nipples. The full flow nipple has the same threads and will fit onto my ball valve, doesn't neck down as much and accepts 1.75" ID hose instead. Hence my search for a slightly larger sanitation hose.
Maybe I should use the regular nipple and hose and be done with it. I just really don't want a clogged drain with a holding tank
full of crap. What are your thoughts?
