Just to report back on this thread, what follows is my twisted 11-week path to resolution of a crack in one of my water tanks plus hairline cracks around the inspection ports, and difficulty getting a good seal on the Quest fittings on both tanks:
Kracor initially said that they could quote replacement roto-molded tanks, but when it came down to it, they have been acquired by Yamaha and will now only quote large quantity orders. South Shore Yachts was able to quote new tanks from a third party but at over $1000 each, plus shipping to Florida, seemed cost prohibitive. Ultimately, I used a Florida tank manufacturer & repair facility, Seelye Inc., in Ocoee, FL to repair the crack in the tank. The cost to weld an 8-inch crack was $65. They tested it to be leak free but there is no warranty. On reassembly, I had trouble getting a seal around the suction fittings, which are Qest elbows, but found that if I first connected the tubing to the fitting and then screwed it in, I could get another couple of turns on the fitting. Both tanks are essentially leak-free except for a little weeping around the inspection ports if overfilled. I plan to avoid overfilling. While at it I also replaced the 4" o-rings on the tank ports (AS568-240), and on the old-style Jabsco suction strainers (AS568-131) and installed a Teflon back-up ring (AS568-007) under the strainer cover screw heads. Now on to the next adventure... -- Tim Rutherford Chamamé C&C 36' - #244 On Sat, Jan 13, 2018 at 8:45 PM, Jim Watts via CnC-List < cnc-list@cnc-list.com> wrote: > I think using G-Flex would be a much better bet than using 105/205.
