Tip #2: Wait for Temperature to Drop

Timing isn’t always important, but it is a handy tip to keep in mind.

The premise is to look for the temperature to drop a bit (not a lot!) and then pouring in the handful of rock salt.

By waiting, you can test on the go and see whether or not there’s a difference.

It’s a subtle trick that tends to work well as long as you are patient.

When using rock salt in RV holding tanks, you have to take initiative by getting the salt ready. Once you do this, wait for the temperature to drop slightly (0 degrees celsius) and go from there.

This will allow you to test the system and see how it holds up. This is key with using rock salt in RV holding tanks.

Tip #3: Stop Using Anti-Freeze

If you go past this number, you are going to have issues later on.
