Clack Water Softener Review – Read Before Buying!

Water softeners and filters can be an important and necessary part of homeownership, and it is just as important and necessary to find the right one to suit your needs.

There are so many things to consider, such as the price of the unit, how big your house is, how many people are living in the house, what type of water you have, how handy you are, and how much you would like to spend. Here, we’ve broken down the details on one of the top water softening and filtering brands today, Clack.

Water softeners come in two main types: salt-based and salt-free water softeners. There are pros and cons to both types of water softener, and perhaps the main argument for using a salt-based system is that it softens the water in a traditional sense.

They are great for larger capacities and extremely effective, but they also remove the water’s healthy minerals, cost more, and aren’t as environmentally friendly. If you choose to go with a salt-based system, Clack offers some high-quality component parts for your water softening system.

Why Purchase A Softener?

Hard water is an issue that plagues many homeowners. There are diverse issues hard water can cause, such as limescale buildup and staining of sinks, appliances, or anything else it touches. Additionally, it can decrease the life of appliances like dishwashers and washing machines, costing homeowners more down the line.

Glasses and cutlery come out of dishwashers spotted, and clothing, skin, and hair can feel less clean as hard water prevents soaps from performing optimally. 

Certain skin issues like rosacea and eczema can often be exacerbated by hard water. Pipes, showerheads, and faucets can be ruined by hard water as well, and water flow can be reduced because of limescale buildup.

If you find that you are having issues like these, you may have hard water. The minerals that are generally found in hard water include calcium, magnesium, manganese, copper, and iron. If you are unsure whether or not you have hard water and would like to know, testing kits are available. The ideal mineral count in water is below 7.1 mg/l or ppm.

It is always good to do your research (that’s why you’re reading this) and get some professional advice before you dive into any big purchase or any decision that will affect your quality of life.

Water is imperative, we need it to survive, and it is crucial for our daily tasks. It’s important to make sure you are getting the best quality water softener for your money, and this is why we researched for this Clack water softener review.

What Is a Clack?

Clack designs and manufactures salt-based water softening system components. Through ion exchange, scale-causing minerals, like calcium and magnesium, are exchanged with sodium from the salt and washed away during the softeners regeneration process.

Because of this process, your pipes and appliances last longer, and you will notice a difference in your hair, skin, and laundry. Those with skin issues such as eczema or rosacea can notice beneficial effects once the dryness-causing minerals have been removed from their water.

Generally speaking, it will be a water treatment professional who will be using or recommending Clack parts. Additionally, you can purchase their parts on

The warranty itself is almost enough to get us to trust Clack system components. Clack offers an overarching five-year warranty on all its parts, which really stands out in the water softening system world.

Water softening valves are very sensitive equipment, and salt-based softening systems often need maintenance, so the fact that Clack backs their valves with this comprehensive warranty means they have confidence in their effectiveness.


It is recommended that any Clack valves you purchase for your water softening system are installed by a professional. As stated above, water softening valves are very sensitive equipment, and unless you are an accomplished DIY-er, it’s best to make sure your water softening system is working the way it’s meant to.

What To Expect From Clack

You may find Clack valves installed on your saltwater softener system. They are manufactured from composite plastics and have a flow rate of 27 GPM. Clack is known for producing some of the most reliable, long-lasting, and user-friendly valves on the market. Here is what some water treatment professionals have to say about Clack:

The WS1 Valve by Clack


Clack is known for having good efficiency. They can use as little as $2-3 of hydro annually. Although there are higher efficiency valves on the market, they will be much more efficient than any older valve and softener combination.

Total cost, of course, varies depending on water costs in your area, how much water you use, and the quality of your water. The cost of the valve itself will vary from retailer to retailer, and of course, if you are going through a plumber or other water treatment expert for installation, there will be the added costs for labor.


Clack is the valve most recommended by professionals because they are rarely ever replaced. They are known specifically to be the brand to go to when a client has particularly hard water or other problem water like high iron or sediment. The success rate with Clack valves has been proven over and over again.

In general, the initial investment in a Clack valve and the cost of having it installed will pay off in the long run due to its efficiency and longevity. Many water treatment specialists will use these component parts in their own homes and have them on hand for emergencies.

As stated above, water treatment professionals are often fond of Clack. There are some technical reasons for this: they only use a single-piston, plus spacers and shafts, so there is only one moving part in the system. This is very different from some water treatment component manufacturers who have several moving parts in their valves, which can cause repairs to be needed on a more frequent basis.

Unfortunately, Clack valves are not available to purchase online, only to traditional water dealers, which can drive up the initial price. Repair costs for a Clack valve, however infrequent, are usually quite low as the repair itself is quite easily done.
