How would you guys rate the taste from your water tanks?
A- fiji bottled water quality,
B- gas station near Tijuana tap water quality,
C- tastes like plastic death and you'd sooner drink from the sea than sample the tank water again.
I have cleaned the tank and bleached it, I have replaced all the feed lines and the fill line and the foot pump, I only fill with clean water from a food grade hose.
I treat the tank with a drop of bleach every fill, but as you can guess by now I still have a HEAVY plastic taste starting after the first week that increases with age.
Any thoughts, ideas, experience?
Time for a new tank? lots of Kool-aid?
Our factory Ronco rotomolded water tanks did not have a plastic taste. Both have been replaced due to increasing capacity needed and shapes better fitted to the boat.
Having said all that I know from first hand experience that a small mistake in temperature control when "cooking" the liquid plastic in the rotating mold can impart a taste/smell that will never (!) go away. I know this because I installed a new larger Kracor brand rotomolded tank in our prior boat and after battling the taste problem for a year gave up and got my money back from the retailer. Good thing they were an honest company; and they did explain to me how things can go wrong with this particular industrial process. (They have sold oodles of tanks and related marine plumbing parts and had/have a good track record as a vendor in Seattle.)
Talk to Ronco and tell them your sad tale. It's been a long time since EY bought that tank, but they might give you their super-boat-show-special price on a new tank with a new warranty. They have always treated us very well. Also, if you go this route, it's a great opportunity to adjust the sizing of the tank and location of any ports, inlets, or outlets to better suit your boat.
Nowadays, we have two tanks, one very-custom welded ss tank and one welded plastic tank. Neither imparts any taste to the water. I also drain and scrub out all tanks each fall when winterizing the boat. Throughout the boating season, I drain and scrub down the interior of the main ss tank with some bleach on a wet rag, and then rinse it. The taste does not change, but we do not like to see little teeny algae bits in the water, "safe" though it may be. And another nice thing about a newer tank with a 6" clean out port, is that you can look inside with a flashlight any time to see if anything is growing there....
"Just one more thing"... we do not have deck fills or a hose from deck to tank. On the Olson the tanks are filled through the inspection ports. We just lift up the settee cushion, and drag the hose inside with a little ball-valve shut off on the hose end. Works great. Seemed kinda odd when bought the boat, but we adapted and appreciated that idea in a heartbeat.

ps: last resort is to drink only rum.
pps: Mark's idea is good too: I prefer apple pi
