It's not normal behavior for a ball python to soak. Excess soaking is just a sign of mites or other skin related issues.

Take out everything in your enclosure. Wash the essentials with hot water and throw away what ever else you can't wash. Keep your set up to a bare minimum. Just a water dish and a hide.

Change your substrate to paper towels until all the mites have been treated.

Have you treated the enclosure with Provent a Mite? I assume thats what you mean in your original post.
In the mean time you can give your snake daily soaks with a drop or two of dish soap to help relieve him of the mites.
