Need ReplacementWastewater Tank for CD36

[Jody Thomas]

My 1979 CD 36 is holding up beautifully, except that the head tank,located in the v-berth has a big crack in it. The manufacturer's label is mostly worn off so I can't figure out who they are and therefore if they are still in business making the same tank. I do know that it is a 24 gallon capacity tank fitted for under the v-berth, the last three letters of the company's name are COR and it was located in Wisconsin. Does anyone know this company? Alternatively,has anyone replaced this kind of tank lately and where did you get the tank? Any help appreciated as we live aboard and, as you can imagine, it isn't pleasant.... Thanks

Search the past messages for holding tanks. There was a discussion within the past month which includes the phone number of the company.

Jody,

I have been dealing with this exact same problem for quite sometime now. Most regular readers of this board are familiar with the previous posts on this matter that I started awhile back which Bob has referenced. The original tank manufacturer was "Kracor Inc." I am very familiar with the company and have had many conversations with their engineering department. Kracor has the mold for the tank and will make you a new tank but the cost is quite high, $360.

I have extensive info on this matter, anything from the original engineering drawing of the tank, original manufacturer info, replacement or repair prices, alternative tank sources, material options and the final option that I decided on: I built my own.

At this point the tank that I've been constructing is basically completed except for the exterior. It has been a challenge to construct because of its tapered shape. It will outlast the boat it is so strong. No more cracks and spills and odors. Much work, but the results and peace of mind it will bring is worth the effort. Far better than any polyethelene tank that I've researched, period.

I have documented the construction of the tank with photos and am willing to share them with anyone that may be "seriously" interested in constructing a substantial replacement for the original polyethelene tank. I can offer details on the type of materials and supplies that you would need to build one.

My new tank is built of 1/2" plywood, 6oz and 9oz fiberglass cloth, 4oz fiberglass tape, fillers, West System epoxy, bronze plumbing fittings, Marelon and PVC.

I recommend anyone with a CD that has any continual head odor problems make access to the holding tank plumbing fittings that are welded into the tank wall and check them for cracks. I have a photo of the cracks that developed in mine and I can e-mail it to anyone having a odor problem that may suspect the tank.

In the CD30 24 gallon bow tank (same as 28 and 36 CD's) under the V-berth you will have to remove the tank to inspect the fittings unless you have enough room to get a small mechanics mirror to slip between the liner opening and the forward top of the tank to see the tank front. In the CD30 the anchor locker floor is covering the area where the plumbing connects to the tank. Anyone with a polyethelene tank needs to inspect these fittings regularly!

If you or anyone else is seriously interested in additional info regarding the tank please post a reply message and I will discuss this entire matter at further length.
