Table Salt in Gray and Black Tanks?????

We are currently staying in a very hard water area. We DO NOT use our Fresh water tank but last year our gray and black tanks got a hard water residue on them and would not register correctly. I got them cleaned up and am hoping to prevent the same thing again from happening.

My question: Has anyone used table salt possibly pool salt directly in the gray and black to keep hard water from forming?

Does anyone see a drawback to this?

Thanks in advance

    I have a friend who uses Calgon water softener in his black and gray tanks. He says it keeps the tanks clean as there is less residue when you empty the tank. I tried it last year and it seemed to work OK. I know when you mix the product with water it seems to make it more slippery and soap foams up better. Has anyone tried this?


    Yup, and my old sensors (1985 MH) work fine.

    The owner's manual for the Komfort recommended rock salt in the black and gray tanks to clean the sensors. Won't hurt anything to try it. Good luck.



    Will do Thanks

    I don't understand the thought process of some posters. I know that they are different sensor systems on the market and that some of the after market systems work much better. I also know that my 20 year old sensors work just fine. So to say its a waste of time and energy to make them work, or to say you'll know when it is full, well, yep you sure will and it just might be to late.


    Yep, I agree. I did a lot of research here when I bought my used and then new trailer. To date sensors work perfectly, and I'm glad they do. Maybe I'm OC, but if it's there, I want it to work properly. It doesn't matter if I can also tell that the gray tank is full when it backs up into the tub. I want my sensor to tell me; and it does.

    We have never had a problem with sensors not working in many years until be were stationary in a place that had terrible (I mean terrible hard water) After a few months, they quit working properly and it drove me crazy.
  • I don't use my levels panel. I check it once in a while but it never has worked right in any TT I have had. So I don't bother.

    I use the direct detection method.

    Fresh water - grab a flashlight and look in the compartment. Very accurate, I can see what is left in the tank.

    Black water - turn the pump off, step on the pedal and look down the hole, again with the aid of a flashlight. Deadly accurate, if the soup is close to the neck, time to dump.

    Grey water. Shower and wash dishes until I am ankle deep in shower water. Time to dump.

    Works for me!!

    My indicator panel isn't worth the powder to blow it to bits!
