Argosy holding tank crack

[blondie3265]

Hello Everyone! Its been awhile since i posted. But we got the 74 22' rear door Argosy project started. And the holding tank for the toilet is bad. It has a long crack on the underneath side of the tank. Can these be repaired? I'm guessing not. So ok where do i find one to replace it? Right now there is no bathroom. Also the plastic sink top, Does anyone have any good ideas on this fix. It doesn't look the best. But it will do if it has too. Thanks

you have any pictures of the damage ? there are several other threads going on right now about tank repair.

The company that made your holding tank is still in business.
I had to buy a new one for my 1977 Argosy 22.
There should be a number molded right into the tank itself. This is the part number that Inca will ask you to provide when ordering a new tank.
Here is there website: Inca Plastics. They were extremely helpful with my order and I got the new tank pretty quickly too. Use the "Contact Us" link to get in touch with their customer service.

For the plastic sink I used a two-part epoxy putty from Por-15. It filled and sealed a crack in my bathroom sink and stress cracks in the interior plastic endcaps as well. Make sure you smooth it out while it is wet. It is sandable but takes a bit of elbow grease to do so. Here is a link to the putty: POR-15 Epoxy Putty.

Polyethylene can be repaired by plastic welding. It is a solid repair if done correctly.

But I'd be inclined to replace it myself.......

Check with TikiHut, I believe he had a similar problem.

Thanks for all the information. Yes i have photo's of the crack. Its on the bottom of the tank. So i'm thinking it needs to be replace because of where its at. I'm going to guess that it may have had water in it and froze. Its about a 7 inch crack. As for the bathroom sink i was wanting to replace it with a new one. Also some of the wood needs replacing in the kitchen what is the best way to go on this? Its a very thin wood i found 1/4 inch birch to maybe use. Any thoughts on this? Thanks

I agree with Sundance...
You can fix it but why risk it...
I was pretty sure my new tank cost me less than $150. That was the largest tank on the trailer too. It was the freshwater tank.
When it came, it looked just like the old one, only it wasn't yellow and cracked! It was nice, shiny white!

What wood are you talking about? Is it load-bearing? I am not sure if there is much wood in the Argosys. Most of it is vinyl-clad aluminum.
If you are putting a new top on the vanity for the bathroom then pick up any old RV bathroom sink.
If you want one cheap you can get one from on of the many RV surplus places that operate in and around Elkhart, IN. One of them is Bontrager RV Surplus in White Pigeon, MI. I picked up a Magic Chef stove from them with a small scratch in it for about half the cost of a new one! It looked BRAND NEW.
Check out Bontragers at Welcome to Bontrager's Surplus Inc.
I am sure they will have what you are looking for.
