Camano Troll Sewer Bladder

[MWhit]

We have a contract on a 1997 Camano Troll. During the survey we found the trawler has a sewer bladder under the steps in front of the head. Is that normal? Did the Camano have a solid plastic holding tank at some point? We have no experience with a sewer bladder. Are they good? Cause for concern? Your thoughts greatly appreciated.

I can’t say a bladder is normal. My 2003 Camano has a plastic holding tank. The location is the same though.

Thanks. How many gallons is your holding tank? In The 1997, the macerator is on the head. Is your setup like that?

15 gallon I believe. My boat has the vacuflush system, with most of the components under the front of the vberth and the macerator for overboard discharge behind the cabinet in the head closest to the starboard hull, bolted to the bulkhead it shares with the helm.

Ok. Thanks. That is helpful.

Bladders are the quick fix when you ruin a plastic holding tank, you can cut the tank out but you can't get a new one in the space. I used a flexible bladder for water after I over pressured my water tank due to a blocked vent, the tanks are only tested to a couple of psi because they aren't designed to be pressurized at all. My guess would be a similar event happened to that vessel requiring tank replacement.

My boat has a macerator on the toilet, and another on the discharge from the holding tank. I would expect yours to be similar.

Te first picture is the holding tank in my 2002 Camano, the second is the macerator pump in the overboard discharge. Dave
