The hose on my gravity tank is about eight inches long. It has been in situ for several years now, no degradation so far. If a blockage took place there is an inspection hatch in the top of the tank, through which the outlet can be rodded.
My previous pumped system caused endless trouble and I would definitely not go back to one.
Similar set up as mine, except mine also has a separate pipe that leads to the bottom of the tank that you can pump out of. Has never been a problem, also never known a problem on friends boats, who have similar systems.
It would be interesting if any one has ever had such a problem to give details, cannot see how it can happen as it is such a simple system, just as likely for the tank to crack, by that I mean extremely unlikely.
