Is it normal for salt to go down unevenly?
This is perfectly normal and a harmless issue. One block goes down faster as this is where the brine valve is located in the water softener.
The salt is always drawn from the block that is closest to the brine valve, hence it going down quicker.
It is okay for one side to be completely dissolved away before adding more blocks. As long as there is some salt in one of the chambers, then the water softener will make brine and function correctly.

The water softener will stop softening your water, so it needs to be filled up with salt again. Otherwise you will revert back to having hard water.
Our water softener is designed for block salt. We wouldn’t recommend using granular or tablet salt as it can block the tray and cause problems with the brine valve etc.
The clear lid on our water softener makes it easy for you to check your salt.
