To keep this from happening use flush every time you finish a camping trip and make sure ithe tank is compltely clean. Be sure tank is empty before starting the repair.
Oh boy.............sounds like no fun!
What's the "barb fitting"?
Is the spray head near the top of the black tank? Others have mentioned putting in 5-10 gallons of water and/or ice, but that would not seem to be effective unless that spray head is near the bottom of the tank, which seems illogical......but then many things on my FW are illogical!
The mistake I made was not using it each time we camped. We usually only use the FW six trips per year, and two of those trips are for 30+ days. I tend to use the flush fitting only on the last morning before putting the FW back into storage, usually for several months. From what I am reading on the 'net, there are MANY problems with these so called "flush kits".
I think I will try connecting a hose to the flush kit fitting and turn on the water with minimal pressure and let it "run" for several hours. It might do nothing, which I suspect, but then again it might get things moving again. I'll do that one day soon (we're camping for the next 3 weeks) just in case it breaks through the crud; wouldn't want to over flow the black tank! I don't see where I could make anything worse by trying. However, taking things apart doesn't sound like something I want to do here while we're camping. I might wait until we return home and tackle the work when it's in storage again..
