Replacing black water tank hoses

[freightdog]

I have a Pearson 303 with a marine head with a 3 year old black water bladder (tank). While the integrity of the system is tight (no leaks), there is a slight smell around the bladder and below the setee. The hoses are probably 30 years old. Do oders eventually permeate through hoses and not leak?

I know when i got Dutch all the Hoses (Black with wire in them ) needed to be replaced they did not leak but the wire is steel and rust then the hose gets weak. you can go to any HomeDepot and they sell the Sanitation hose alot cheaper than West Marine oh it is white and no wire.

Always. There is nothing that can go 30 years.
