    Sanitize water lines.

    What is the correct % of water and bleach to sanitize the water lines ?
    I want to get it right this year, so I do not taste bleach for a month .

    1/4 cup of bleach per 20 gallons of water in the holding tank and heater. Run it to the faucets until you smell bleach. Let it sit for 4-5 hours, and drain. Fill the holding tank and water heater with regular water and drain, 3 times. Then 1 cup of vinegar per 5 gallons of water in both the holding tank and water heater; run it out to the facets. Drive it around for a bit to agitate the water then let it sit for 24 hours. Drain and flush 3 times.


    Edit: Ouch! I thought my memory was better than that... It's NOT 1/2 a cup for 5 gallons, it's 1/4 cup for 20 gallons... I corrected my post above. Here is the link I reference when I sanitize my system: https://www.sanidumps.com/sanitizerv...atersystem.php

    Since we are on well water at home - no chlorine, I always add 1 or 2 oz of bleach when I add water to fresh water tank. Only carry about 25 gallons of water in tank for flushing commode when traveling. We buy bottled spring water for drinking and cooking as some of city water at campsites it's that good. Last campground the city water had so much chlorine it had strong odor, ok for showers and washing dishes but not for drinking.

    Make sure it's the regular concentration and not the ultra consentrated stuff or you'll be adding way too much at 1 cup/5 gallons water

    Also you have screens in your water system which need to be cleaned AFTER this process. ( some near the pumps, some in the faucets themselves. If you have any algae in your system the beach will k ok off the storage tank and flow through the pex to a screen. On our sailboat we have a similar stem. For me one step of the SOP every year in sanitization is to also check ALL the screens after shocking it.

    There should be detailed instructions in your GD manual for your trailer. I use 2 cups regular Clorox bleach for my 50 gallon tank (including water heater) To get the bleach in I use the power fill setting and starting with an empty hose attached to the trailer I use a funnel to put the two cups into the hose, then connect to faucet and then use power fill to fill tank. Then use the pump to get it to all of the faucets/HWH, toilet outside shower, etc. I then power fill the tank to full again. You want it to sit for at least 12 hours. Then drain and use the city water setting to flush the system. Drain and refill the FW tank several times. Now fr the last step I dissolve a 2 cups of baking soda in a 5 gallon bucket (sanitized before use) and suck it into the fresh water tank using the pump. Then power fill to full and use pump to distribute through the system. Then fill tank again and let it set for a few hours. Then flush everything again. The baking soda helps remove the chlorine oder and taste.

    Hope this helps

    As Keith referenced in his post #7 , manuals are also available on the GDRV website. Our 303 is stored indoors offsite over the winter and I have used the online manual for me and manuals for other models and years for other folks many times.

    Here's the link - page down and you will find the manual for your 2016 (same as for my 2014) Reflection: https://www.granddesignrv.com/owner-...owners-manuals
