Does anyone know where I can get water tanks for a H37C... I've attached a picture of the monsters. No luck at Ronco. I'm leaning heavily toward blatters... Ron

You'll be sorry.
Ron: What do you mean that you had no luck at Ronco? Did you call them? They will make them for you. Bladders are not a good solution. As you heel the bladders will rub in the hull and wear holes in the material. Then you will be replacing them again. Besides this they always add a rubber or plastic taste to your water (if you plan on drinking it). I doubt that shock treating a bladder does it much good either.

Did you try...
flipping and flopping the drawings? They can be oriented any direction, 'cuz there is no top or bottom till the fittings go in...and you get to spec where they go. You don't show any dimensions in your photo, but Ronco has a zillion tanks that shape...and the objective isn't an exact match for a tank, but one that fits the space without sacrificing enough capacity to matter. If you really can't find a Ronco tank that fits the space, you're better off having an aluminum tank fabricated than installing bladders. Aluminum is ok for water...and you'll lose a LOT of capacity with bladders.

The mold has to exist, Steve...
That is, unless you want to pay an extra $600+ to have 'em make a mold to your specs.

Dura Weld
I'm in the process of replacing the alum water tank on my H-45. On 9/28/02 I sent out a # of email and Faxes to Ronco, Dura Weld etc. I received an immediate answer and a quote from Dura Weld. So far no one else including Ronco have replied.

I tried
I talked to Scott at Ronco and he didn't sound too hopeful. I sent him some drawings with dimensions and am waiting for a reply. I'll follow up in a few days. As for the bladders, if I go that route, I will cut the tops off the aluminum tanks and use them as frames to hold the bladders. The bladder mfg's claim no rubber taste, so we will see. I REALLY don't want to go back to aluminum if at all possible, but never say never... What's up with Dura Weld???? Ron/KA5HZV

I think I've got it licked.....
I can get tanks fabricated at Duraweld for $440.00 a piece. 3/8" poly with baffles and female fittings installed. Whatdaya think???

That's a HIGH price!
If you check it against comparable sizes from Ronco, I think you'll find it's about double.

Maybe, but it isn't that expensive if it includes
the up front fabrication cost for a custom made one. No ?!

I wish that were true. Ronco doesn't have a tank I can use unless I want to buy the mold. I checked with a company Steve Dion suggested and they quoted $515.00 a piece. These have to be fabricated from sheet plastic. Any other input you may have is welcomed and appreciated, but I think I can scratch Ronco off the list.... Ron

Welded Poly
Ron: My understanding is that Welded Poly is actually stronger that the actual material (not sure that this is REALLY true). But the point being that a tank built out of sheet stock is probably a better tank (consistent wall thickness). They can also make the tank out of any thickness that you want too. I presume that for the price that they are quoting, that baffles are included too?

I'd get a quote for aluminum
Aluminum is a bad choice for WASTE holding only because urine is so corrosive...that doesn't make it bad choice for water holding. Average lifespan is at least 20 years. So, before I'd spend $900 including shipping, I'd check with some local aluminum fabricators. If you can't save at least $300 over the quotes you've gotten to fabricate plastic, I'll be surprised.

Depends on the quality of the welds
An unbroken surface is usually stronger than any weld, but really GOOD heat welding can be quite satisfactory. The key is in melting enough of the wall into the new poly...if they don't skimp on that, the tank should be ok. I'm a lot more comfortable with the idea of a welded plastic water tank than I would be if it were a holding tank. And there's something that bothers me about that company's holding tanks...Their WATER tanks are polyethylene, but their holding tanks are polyPROPylene. I don't know of any other company who sells anything but seamless rotomolded polyethylene tanks for waste holding. Remember...anyone can set up a company in their basement or garage and put up a website to sell their product(s). Caveat emptor, especially for the price they quoted.

Steve...
Yes, baffles, too. Without starting a war here, I don't drink, cook or eat out of aluminum. Maybe thats just my little quirk, but I don't do it. So, like it or not I'm down to plastic or bladders. I'm still looking for someone local who can build the tanks. Houston is the biggest city in Texas, so there should be someone close by. What are your thoughts on cutting the tops off the old tanks and using them to support bladders?? Ron

I do not like bladders for anything other than...
Ron: I do not like bladders for anything other than a temporary solution(just my opinion). When you check the price of a QUALITY bladder tank you may agree that it is not worth the trouble. PVC bladder tanks are no very expensive but I would doubt that you are going to get more than a couple of years out of them at best. PVC is not very resistant to abrasion. I would think that the rolling and slipping back and forth on a sailboat would make them wear out in a limited amount of time. Once you start spending over $200 for a neoprene tank you get to the point that you may as well just get a cheap poly tank and be done with it. It's your boat and it's your money. When I buy something I like to spend a few buck more and purchase quality. This is not something you want to be messing with again for 10-15 years.

If you find someone...
If you find someone please post. I also find it hard to believe that with the size of the boating industry in Clear Lake that there is not someone who repairs tanks. Have you checked with Blue Water, WM, BoatUS bullentin boards?

Plastic tanks cannot be repaired, Ron
Heating welding is the only thing that will bond poly to poly, and the stresses that caused the crack in the first place are likely to pull a weld apart again. The only repair that can be successfully done is a fitting on which the weld has broken loose--and that's only if the tank is a water tank. NObody will even work on a used holding tank. When a metal tank springs a leak, it's almost always only the FIRST leak, especially if the tank is more than 10-15 years old. Better to replace than start a never-ending battle that will only end with a new tank anyway.
