AO Smith Salt-Free Water Conditioner Descaler Reviews

The AO Smith Water water conditioner system is a unit specially designed for those who want an affordable yet functional and long-lasting salt-free water softener. It’s a simple system that does what’s it’s expected of it without a lot of issues.

Softening Capability

The AO Smith water conditioner system uses salt-free technology that’s highly capable of treating water hardness in an entire house.

The tank is filled with a dependable scale control media which naturally and safely inhibits calcium and magnesium hardness minerals from binding and forming limescale.

The media makes the hardness minerals really ineffective such that they lose their adhesive ability hence preventing scale buildup in pipes and plumbing. It can efficiently tackle water hardness levels of up to 25 GPG.

On top of that, the descaling media of this unit does not completely remove the hardness minerals from the water like the salt-based systems. It retains the calcium and magnesium ions, so aside from stopping them from forming limescale, you will still have these healthy minerals in your water.

System Capacity

The capacity of this AO Smith water conditioner is as well commendable. The media it uses can reduce scale buildup for up to 600, 000 gallons before requiring replacement.

That’s a pretty high capacity that should guarantee you around 6 years of service depending on the level of hardness of the water coming in your house. If you are a household of 3 to 5 people, this would be a suitable option as you won’t have to worry about changing it out for a long time.

Regarding the water flow rate, the AO Smith descaler is designed to treat a maximum of 7 gallons of water per minute.

For small to medium homes, this rate will do fine as it’s sufficient to run a whole household, but for larger homes with high regular consumption, you may find it a little slow.

Installation and Maintenance

You will break no sweat setting up this unit. It’s a single tank with only two connection points for the inlet pipe and output pipe. Therefore, if you have done some DIY home projects or installed a water filtration system, then you can set this one up without any difficulties.

It’s designed to be installed where your main water supply enters the house to deliver descaled water to all subsequent outlets plus it’s a completely sealed, self-contained unit.

It requires no electricity or draining, hence you can even install it outdoors provided it’s a place that will keep it away from the elements.  

Maintaining this unit is something that won’t give you any headaches too. It’s quite maintenance-free because you just install it and leave it to work. No monitoring required and after the 6 years are up, you replace the entire unit with a new one.

To conclude, this AO Smith Water descaler system is an ideal option for anyone who is primarily looking for a quality and durable salt-free water conditioner without the extra filters. It’s built for nothing else but preventing scale buildup which it does well. If you are on a budget or don’t need an additional filter system, this would be a good investment.
