Nice product - hope it does what it says.

First, this was a well made product, and I do think it's very important that when you install this, you ensure you have a valve on both ends so you can isolate it before replacing the cartridge.
I do want to say that I think the description is a little deceiving. Specifically, it states it supports up to 10 gallons per minute, but don't let that fool you. This isn't like a sediment filter that really does limit flow to a specific volume. This unit is designed in such a way that as much volume as you need can pass through the fittings, but it likely can only chemically treat up to 10gpm. I was initially concerned this would reduce the rate of flow to my hot water heater, but after examining it closely, that's not the case. I have a roman spout that is rated for about 15gpm and it flows just as good as it did before.
As for the treatment, just hope it does what it says, like most people I really have no way of measuring the effect on the hot water heater. Maybe the first time I flush it I'll see a difference.

Worked for our hard water

Installed this prior to our tankless water heater to minimize calcium buildup in the heater. Works well, easy to install in line. Just need to remind myself to switch the filters when needed

Works with magic and unicorn tears. :o)
It is not a filter. It is a water treatment system.
The stainless steel head is robust and a nice solid chunk of metal. Easily could withstand brazing/soldering, on the spot, with the cartridge off.
The 3/4" NPT inlet and outlet has nearly a clear flow path, so your GPM, will not be reduced. Install a ball or gate valve in front to permit easy cartridge changeouts.
The tee must be orientated to the water flow, use the arrow on the side of the tee, for the water to get treated while flowing.
There is an elevated tab in the tee with a single hole for directing a small portion of the water down into the center whole of the cartridge.
The water slowly dissolves a small amount of food-grade polyphosphate from the beads and, using the venturi effect, the water is then pulled back through the 8 holes in the cartridge perimeter and through the 3 holes in the tee, surrounding the center tab, to mix with the flowing water.
Only 2 to 3 ppm is needed to treat for scale.
From past uses at a different home, I've gotten about 20,000 gallons out of a cartridge with still some beads rattling in the bottom when replacing the cartridge.
I would say that if you used less than 2,000 gallons a month then one cartridge should easily last a year.
The cartridge threads are plastic and you can easily cross-thread them if you get in a hurry replacing the cartridge. Just make sure you get the threads started straight and it screws up with no problems.
The threads do no provide the seal, it is the o-ring so once hand-tight that is tight enough.

This thing last WAY longer than 6 months. I had it installed on the line supplying filtered water to the tankless water heater. After 12 months I had the service technician come to service the water heater. The guy said he had been servicing heaters for 15 years. That my tankless heater was the cleanest he had ever seen. He flushed it and performed all the steps. He found at most 2 pinheads of scales. I am going to keep using the same installed filter. Just in case, I ordered another one today for installation on the line leading to the UV filter. It can't hurt.
