So WHAT is the problem?
Is it just that I have a different view than you and you feel I should change? I don't think I made any big challenge to to the way you think, so would it not be more civil to allow others to have their ideas as well?
I thought the point was to advise the OP who DOES have a problem!
As I understand this thread, the OP has a black tank that has pretty much iced up and won't dump so chemicals or not won't help.
I'm not trying to change the way you do things.
To those who use chemicals, it really doesn't affect or matter to me if you want to spend several dollars and carry around chemicals for your holding tanks.
I do want to give a perspective, to others reading the forum, that there are a huge number of RV'ers who do not use chemicals in their holding tanks and their holding tanks work just fine.
The message is: try it w/o chemicals and see if it works for you. If you do try it, buy a short clear dump pipe to put on the dump connector before you attach the dump hose. This way you can see the stuff coming out.
Here are 2 clear connectors:
I use the one in the first link that has a valve on it. Once I dump the black tank I close the valve on the adapter and then open gray tank valve to give a good hard flush of gray water into the black tank. I only leave the gray tank open for a count of about 10 seconds and then close it. I don't want to allow the black tank to seep back into the gray tank. The gray water really helps to clean out the black tank. I finish up with the black water tank flush connector.
When we first started owning RV's that had holding tanks (after 25 years in poptop campers and truck slide on campers) we put chemicals in our holding tanks. After a couple of months I forgot to put the chemicals in our tank a few times and realized I didn't see any difference in the stuff coming out. I finished up the chemicals we had on hand and have not used them since.
I have always used a clear short section on my dump pipe so I could see what the consistency of the stuff coming out is. If it was clumpy or the toilet paper was not breaking down, then I would know I needed to change the way I dealt with my holding tanks.
