potable water systems

Hey All,
This will be the first of many questions that I pose here regarding my new found obsession. The PO of The 81' US27 I bought has never used the fresh water system (9 years) so I am betting that it will be pretty tough to get it cleaned out.
My question...For day sails and if the dogs take to it, the "occasional" overnight how often is it really needed? Also, what are some of the "issues" that you have seen with a potable water system that has not been used in so long on a 30 year old boat.

Thanks

P.S. - The head is saltwater flush and replaced recently

Re: potable water systems

First just fill and drain with potable water a couple of times, watch to see if any debris flushes out. Remove all aerators after and clean and inspect. next a strongly chlorinated fill, I have a 15 gal tank and use about a pint of bleach, run to fill all lines and let set overnight then drain and flush thoroughly a couple of times. Should be good to go at this point if no contaminates flush with the last flush.

Re: potable water systems

For daysails and overnights? Totally unnecessary. Buy a 5 gallon water carrier and just use that.

However, if you feel like restoring the system to service, Google Peggy Hall headmistress. Her articles are full of good info on this. It can be as simple as replacing the nasty hoses, cleaning the sink pumps and sloshing some bleach around inside the tank.

I have put my system back in service and I regularly cook and drink from the tank. No odors or funny tastes at all.

Re: potable water systems

This is good to read...I will give it the once over in the spring and if it is too far gone won't sweat it. I was planning on bottled water for consumption anyhow so a 2 gallon jug for dishes will not be a stretch. The only reason to have the system up was really to have as many systems operable as possible on her.

Thanks for the replies

Re: potable water systems

What's the tank made out of ? Is it integral to the hull ? If it is not integral and/or not degraded, then new pipes and possibly pump plus the cleaning as previously suggested should see you right.

Re: potable water systems

Ice, rock salt, baking soda, vinegar into tank and then go sail her on a brisk day to slosh it all around. Scrubs out the tanks. Ice melts, salt disolves and then pump it all out and rinse. Repeat as needed.

Re: potable water systems

I think it's worth having if only to wash your hands etc. Also once you start letting systems fail it's a slippery slope. Just try to keep things working and you'll be better off.

My tank had also been unused for about 9 years. It had some mold but when I went to replace the hoses I busted the fittings. So I cut the tank out and put in a flexible bladder. I never drink it so I can't tell you what it tastes like but I'm glad it's there.

This is the way I am leaning...I really like the idea of as many systems as possible working.

Re: potable water systems

Hello,

Some quick questions:
-Is there a 12volt water pump or just a foot pump?
-Is there a water heater?

Either way, before you do anything you need to know what works and what doesn't. I would add a little water to the tank and then just find out. If the water pump works and you get the system pressurized and there are no leaks then you are mostly good to go. Just clean the tank (see below) and have at it. If the water pump doesn't work or it works but you have leaks it gets more complicated. How much time and money are you willing to spend?

My boat has 2 water tanks, water heater, 12V water pump, expansion tank, etc. All I use the water for is washing (dishes, hands, etc.). You certainly can use a water jug for that, but, if your water system works, that will be must easier.

Cleaning the tank:
Does the tank have an inspection port? If so, open it, and use a sponge to scrub as much of the inside of the tank as possible. I would use a little (like 3-4 drops) of dish soap with a few gallons of water. Clean the tank(s) as best as possible, then drain into the bilge (don't use the water pump). Then fill the tank with about half full and add a capful or two of bleach. Let sit for an hour, then use the water pump and run some water through all the faucets. Let sit for another hour, then drain, rinse, fill and enjoy.

Good luck,
Barry

Thanks Barry
I will have the owners manual in hand next week so it will answer the questions you pose. I am betting foot pump with no water heater as the boat was not a "live-aboard" design at 27' so it will be easier/cheaper to bring back to life.

I will update as I progress

Bill
