Ronco Plastics had a tank that was an almost exact duplicate of the cracked Kracor tanks on my 38, at a cost of about $400 per tank. If you know the dimensions of your aluminum tanks you may be able to buy an exact (or close) size from them.
After talking to Dennis C about his installation, I decided to use Plastimo bladder tanks ($139 at West for the 26 gallon size, with no shipping cost for store pickup). I’ll put the bladders into the old Kracor tanks (after removing the top of the old tank) to avoid any chance of chafe as the tanks move in response to the motion/heel of the boat. Low cost, simple installation, effective, and allows me to plug the old vent fittings under the toe rail of the boat – which can be a source of contamination of the water and of leaks. FWIW, the 35 gallon IMTRA-Nuata bladder tanks (nitrile rubber instead of PVC) are about $300 at West Marine (actually less than if you buy them direct from the manufacturer), and look to be of more durable construction than the Plastimo tanks Rick Brass Washington, NC From: CnC-List [mailto:cnc-list-boun...@cnc-list.com] On Behalf Of Danny Haughey via CnC-List Sent: Friday, November 3, 2017 6:12 PM To: cnc-list@cnc-list.com Cc: Danny Haughey <djhaug...@juno.com> Subject: Stus-List New water storage tanks Hi guys, I've been researching new water storage tanks for my boat. The current ones are aluminum, leaking and well past their life expectancy. Here is what I've come up with. so, I think these are all I've worked on; aluminum for about $700ea w/ shipping 70lbs Pros are weight, direct replacement, not too expensive Cons are corrosion, taste, poor reaction to chlorine SS about $800ea w/shipping 150lbs Pros are direct replacment, food grade, non corrosive, no chlorine issue, no real taste issue Cons are weight Bladder about $220 ea w/shipping super light Pros are pretty easy install, food grade PVC, no chlorine or taste issues, easily replaceable cost effectively, less than 1/2 the cost of next cheapest option Cons are some space modification to utilize full capacity. Custom Poly too expensive to consider Custom Bladder too expensive to consider Thats about all I can come up with any comments from you guys?
