Some I replaced the hoses on my aft head
, which in the end I think the problem was just a leak at a fitting. But I'm sure the hoses were due for replacement.
But last weekend the forward head
hoses permeated and just about chased us off the boat. This was a surprise as that head is rarely used, like maybe 1% of the time. But it has a bad design in that the flow has to go up and I calculated the volume to be .7 gals, so I'm sure it doesn't get well flushed. But I am going to blame using the pink anti-freeze for the hose failure.
So taking my own advise I got the "most flexible" hose on the market, Raitan SaniFlex. It was easier to use that the Trident 101 hose, but it is thinner so maybe that is the reason. But it does bend anywhere as well as they lead to to believe with like the photo
of the hose snaking around, and at the point of it coming out the deck
hole to the head it didn't bend, it kinked instead and will need a 90 degree fitting.
And I hope it lasts longer than the 5 years that is stamped all over it since the cheap
original hose lasted 13 years.
