DIRTY WATER Winnebago Adventurer 33

Hello IRV-2'
We recently purchased a 2007 Winnebago adventurer 33. While in use this week end dry camping. Dark grey, almost charcoal color at times, came out from the fresh water at the kitchen sink. The water would change from crystal clear to dark grey and back to clear again. Would anyone know what this is and perhaps how I can fix it?
Please help...

Thank you

Sound like a charcoal water filter coming apart. If it is only at the kitchen sink, look for an under sink filter.

If it's not the filter, just fill your tank and use a little bleach too. I have a canister filter outside that treats all the incoming water. When my water indicates it's stale or smelly I take the cartridge out and fill the canister with about 1 to 2 cups of bleach and top off with water. I then turn on my diverter valve to direct the flow into my tank. I run all the faucets till I smell bleach. I don't flush the mixture out, I just let it dissolve as I replenish water to the tank. I don't drink from my fresh water tank- only wash and flush the toilet when we're on the road.

Oh my! Looks like a problem of not sanitizing the FW tank regularly. So, you have black mold?, sediment and funk in the tank and lines.

First thought is that there was a new charcoal filter installed and it wasn't flushed of all the "fines" they are loaded with. Makes the water dark, black, cloudy until they are fully flushed out.

If you haven't sanitized the system....it is time to do so. To clean the FW tank, lines and HW heater.



Pretty easy but takes a few hours.

The HW heater has a drain plug / bung (brass plug) on the bottom. If you can tease that out you can drain the sediment and crap out of the tank and avoid pumping it through the water lines. It would be a good idea to replace the bung with one that has an anode to slow/stop galvanic action in the water system.

At the top of the WH there is a pressure relief valve. Got a lever on it. Flip the lever a couple times to be sure it is free working.

Once you have sanitized the system and flushed the system, clean the screen filter on the intake side of the pump. Caps usually unscrew and pull the metal screen to clean it. Replace all the water filters (if you have them) because they are now contaminated with funk and clorox.

Walmart has inline filters for your shore water hose. I call them 'blue weenie' filters. Always use one to filter out sediment and chemicals out of your make up water.

If it was a moldy tank, discolored water should come out of all of the faucets, not just the kitchen faucet. Possible a moldy kitchen faucet line.
