If you live in an area with hard water such as the south east of England, then you’ve probably explored the world of water softeners. These devices remove the hard minerals from the water such as calcium and magnesium, meaning that your appliances will suffer less damage and your skin and hair will be in better condition. 

There are various different types of water softener, and one of the more recent innovations that you may have heard of is a block salt softener. Here’s a look at what they are and the advantages they offer.

What is block salt and why do water softeners need it?

Water softeners require salt to regenerate the resin beads contained in the device, which actively trap the hard minerals and prevent them from being transported further in your household water supply. Salt can be supplied in different forms, including granules, tablets, or blocks.

What are the benefits of block salt?

Longer lasting

As you may have surmised, block salt is supplied in blocks. This means that the salt is very densely packed, so it needs to be replaced less frequently than salt supplied in other forms. 

More consistent performance

Block salt is a uniform size and shape, resulting in more evenly distributed dissolving in the water. This means that the resin beads are more consistent in their performance, and your water will possibly be softer than it would with other forms of salt. Block slat also tends to be more purified, and is more likely to dissolve cleanly without clogging up the brine tank. 

Less prone to bridging

Looser forms of salt can form bridges in the brine tank, which results in hard crusts that impact on water flow. The solid structure and even dissolution of block salt means that it is less prone to bridging.
