I am interested in plumbing a head into a 1980 C25. It has never had one before. Is there well known holding tank size and location info available?

Thanks,
Sean

Go to Catalina Direct from the "Links" page on this site and you will find holding tanks for the various models.

I just switched to a Porta Potti. If you are interested in the C25 holding tank for under the port settee bench, let me know. I also have all of the Trident hoses and a few Jabsco three way valves. I too was replumbing my new purchase when I changed to the Porta Potti.

I would NOT recommend the original Catalina holding tank unless you can re-position the pumpout barb. The tank slopes backwards quite a bit and the original pumpout barb is in the front of the tank effectively leaving about 1/3 of the tank un-pumpable - basically you will have s**t sitting in the rear of the tank that will never get emptied.

I looked into getting a replacement tank with the pumpout barb at the rear but could not see a way to route the incredibly inflexible sanitation hose to the original deck pumpout plate.

You could route the sanitation hose to another location but then it will probably be visible in the cabin.

I opted for a cube-shaped tank under the v-berth. We only use the v-berth for storage. If you do what I did, don't try for the biggest tank that will fit in the space, try for the biggest tank that will fit through the opening to the space beneath the v-berth!!!

Hmmm....I have an original tank, under the aft end of the port settee. It is as you state, with the sanitation intake hose on the top of the forward end, the vent line close to it, and the dump line is at the bottom of the forward end. When I pump it (only twice so far), I also dump a few buckets of clean water through the head and pump that out as well. I can "thump" the tank and hear that it's emptied out, and I can also move the tank a little to feel that it's emptied. There is very, very little left behind.

I have the L shaped interior and mine was in the forward settee right next to the compression post. Its square and not sloped and was mounted level with the barb In one of the lower corners on the port side of the tank. I pulled mine and glassed over the thru hulls(discharge & intake) and went with a domectic pottie that has pump out capabilities. I still have the old tank if anyone wants it, free, just come get it.

Thanks for all the thoughtful response. Several of you have pulled your heads in favor of porta potties. I've heard of troubles with cracked plastic, leaking tanks, and pump out challenges. Would folks recommend going with a dometic pump out model, or putting the time in to instal the thru hull, tank, and deck vent?

Thanks,
Sean

The advantage of a dometic is that you get a lot more uses than with the head/holding tank, but still can have pump out capabilities. If it doesn't work out, I'm only out $140 for the whole thing.

I just replaced my old, obsolete, Wilcox-Crittenden toilet with a new Jabsco toilet, and am very pleased with the way it works. If anyone plans to buy one, they're on sale, starting today, at Westmarine for about $169.99, with a mail-in rebate for an additional $15., making the final cost about $155.

I did the exact same replacement recently. Replaced the original WC with the Jabsco Twist & Lock on sale at WM. I got an additional discount on mine since I'm BoatUS and a WM Gold Member. I wrote it up in my blog/thread "My New Sailboat" on here and took pictures.

I now have the [url="http://www.dometic.com/enus/Americas/USA/Marine/Toilet-Systems/Gravity-Discharge-Toilet/products/?productdataid=96282"]Sealand 711[/url]--a sort of hybrid. It has a ceramic bowl (the ladies like that) sitting on a 9-gallon holding tank, plumbed to a deck pumpout (and vented). It's hooked up to the fresh water system (mine is pressurized) so there's no saltwater--a huge plus for odor elimination. Pull the pedal up and it puts water in the bowl. Push it down and it opens a big ball-valve and flushes. It's the KISS principle--there's no plumbing between head and tank, an no odors. While it's being pumped out, I open the valve and spray water directly into the tank to flush it. Best system I've ever had (or seen). (My system also has a Y-valve and macerator, which I've yet to use.)

Off-hand, I don't know the dimensions of the tank or how it would fit in the C-25 head area. But I could measure it...
