Is it normal for salt to go down unevenly?

This is perfectly normal and doesn’t cause any harm. Your water softener is working efficiently and softening your water thoroughly, even when one block goes down faster. 

One salt block can go down more quickly because of 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. So one block may completely dissolve away, while part of the other one remains.  

It’s not necessary to add another block when one side has finished. As long as there is some salt left in one of the chambers, the water softener will continue to function perfectly. So if you prefer to wait until the second block is almost used up before adding two new ones, that’s fine. Equally, you can top up a single block at a time as space is made in the chamber, if that suits you better. 

When it comes to replacing the salt in your water softener, the most important thing is that you use high quality, pure salt blocks. This will prevent residue forming in your softener, which could stop it functioning efficiently. Some lower quality salt blocks contain caking agents and other additives that produce this undesirable residue.  

We recommend that you buy your softener salt from Harvey, so you can be sure you’re always using pure, high quality salt that will get the best from your water softener and prolong its life.
