[Tiara Open] Number of Flushes?

[dbruce222@gmail.com]

2002 38 Open with VacuFlush and 40 gallon black tank. I am hoping for a ball park estimate of how many flushes I can do between pump outs? I am not sure that my gauge works because I get frequent pump outs to be safe.

I am in salt water but the boat spent most its life in fresh water. Since I travel offshore far enough for it to be legal I, plan to install an overboard system at the next bottom job.

I have a 2000 40. I can do four days comfortably and five if necessary. You can pull your sending unit and clean the rod that the float slides on.
