Fresh Water Maintenance
1. Prepare a chlorine solution using one gallon of water and ½ cup (4 oz) of household bleach. With tank empty, pour bleach solution into tank. Use one gallon of solution for each 5 gallons of tank capacity.
2. Complete filling of tank with fresh water. Open each faucet and drain cock until air has been released and the entire system is filled. Do not turn off the pump; it must remain on to keep the system pressurized and the solution in the lines.
3. Allow to stand for at least three hours, but no longer than 24 hours.
4. Drain through every faucet on the boat (and if you haven’t done this in a while, it’s a good idea to remove any aerators from the faucets because what’s probably going to come out will clog them). Fill the tank again with fresh water only, drain again through every facet on the boat. Repeat.
5. To get rid of any residual chlorine smell or taste, mix up a solution of on one quart white vinegar to five gallons of water and allow this solution to slosh around in the tank for sever days by boat motion.
6. Drain again through every faucet, and flush the lines again by filling the tank about ½ full and again flushing with potable water.
