I changed out my head holding tank pumpout line this weekend. Great fun. the old line was 1 7/8 and the only line I could find rated for this was 1 1/2 so I ended up with convoluted adapters from one size to the other. In the process I found the tank is unsecured and the fittings take the stress when the tank moves. One piece of wood that would have kept the tank from moving aft had popped out as it was barely glassed in.

Q: Anyone suggest a larger tank that would fit the space?

Any tank upgrade suggestions?

Thank You

Ray, the only upgrade I would recommend is get a porta potty.

Yeah, porta potty... not an upgrade. I've had a soft tank for years, I had to replace it once and I'm not overly thrilled with soft tanks, they make me nervous in heavy seas.

Catalina Direct has hard tanks for both traditional and dinette arrangements. They've upgraded these tanks by doubling the thickness of the walls to 3/8", so no concern about leakeage due to splitting . Both are 17 gallon tanks and they run about $180. This is one of the upgrades I'll be making on my boat this summer.

yepper... that looks better, a new fitting to a 1 1/2 line.

lotta money for a tank, but they always were expensive but Nice to have it well contained to say the least.

I wonder if the tanks are still black?

thanks for the link.

I reckon I better study up the CD pages better. Nice of them to support a product over 25 years old...

Glad to be of help.

I've never bought another hard tank, so I don't know how they compare price-wise. My first thought was that it was not a bad price to increase holding tank volume and for peace of mind in heavy seas.

My factory install has the tank sitting on a a wood frame glassed to the hull and secured with steel crate banding. It's held for 20 years in some pretty nasty weather.

Cliff, guess it depends on your definition of upgrade. Mine is cheap to maintain, simple to use and ease and cost of repair.

Redeye, new tanks are white, 3/8" wall thickness and opaque enough to see the water line in bright light.

what works really well in marine applications is the foam in a can, you can get it any home center, home depot etc
it bonds well to the plastic and hull, it will hold it in place and prevent future failure, I used it to secure a couple of items
they have minimal expansion and maximum expansion, be carefull with the maximum expansion, and if your in my agegroup the movie the blob comes to mine, it expands alot so be carefull
