It's still there & we are now at the point in 2 weeks that we can FINALLY use our new trailer. Obviously first step is to drain he water. Since water has been sitting there all this time, I'm thinking we need to sanitize the system. Am I right? Other newbie questions - do we remove the water filter first? What do we need to do regarding the hot water heater? Remove heating element? Any & all help is greatly appreciated.
Doxies: Looks like no one's helped you out here. I looked for something already written in the Library, but didn't see anything. I'm not sure you need to sanitize, but it won't hurt if you do.
Here's what I do:
Drain your FW tank. Remove your filter and re-install the casing.
Now fill the FW tank using bleach. You'll want to use 1/4 cup bleach per 15 gal of water. Some people mix the bleach into a gal or so of water and then pour it into the FW tank. I just pour the bleach into the tank. It will get well mixed as you fill the tank. (If you don't have a gravity fill for your tank, pour the bleach into the hose, then hook up the hose.)
Fill the FW tank until it's full. Turn on the pump and pump the bleach solution through all the lines. Now let everything sit for at least 4 hrs. Overnight is better.
Drain and re-fill the FW tank 2 or 3 times to rinse out the bleach solution. Then put enough water in the tank so you can pump it through all the lines. Flush the bleach solution out of the lines and you're done (a minute or each for each line).
Re-install your filter.
Note that this hasn't gotten the couple of feet of hose between your city water connection and the point where the pump comes in. If you want to get this, do the bleach-in-the-hose bit and attach the hose to the city water connection and run one of the faucets for a minute.
