  • Perspective from water treatment professional
Size: 32,000 Grains
I've been in water treatment for 15 years. Six years of that has been spent in industrial water treatment with RO systems up to 1600gpm, pretreatment by softeners the size of pick up trucks. Various chemical injections and multimedia filtration. Primarily in the oil, gas and power plant industries. This system is very small in comparison but the science and process is the same. My house hold water treatment system is as follows: city water (surface water)-meltblown cartridge-carbon block-carbon block- softener (Aquasure 32000 grain)- drinking water RO. Please let me elaborate on a few things to make sure you are setup for success. Install a chlorine removal system prior to the softener. This will extend the life of your resin. Any whole house carbon filter will be sufficient. Stay below 2ppm chlorine. Install a sediment catching filter (string wound or melt blown). This will likely help with differental pressure on softener between regenerations and increase overall water quality. Perform hardness test prior to purchase for proper sizing. Sizing a the softener too small for your use increasing regeneration frequency. Which will shorten the lifespan of the resin. However, the softener will still produce soft water throughout its lifespan. This is a 32000 grain softener. It has the potential to remove 32000 grains of hardness causing minerals (calcium, magnesium). My feed water is 5grains per gallon prior to my softener. If I am to utilize 90% of this resin capacity prior to a regen, I would be able to soften 5760 gallons of water before I should Regen. 10% is reserved to prevent hard water/resin exhaustion and to allow time for time/metered based regen to kick in at 2am. This leads me to probably the second most important thing to consider. The control head is programmed to regen at 1000 gallons. This is extremely conservative and likely based on a feed hardness around 25-30 gpg. The more you regen, the shorter lifespan of the resin. This could mean shorter lifespan of the softener if you do not have the resources to cost effectively replace the resin. Please, whether you have to send off a sample of your water to a lab or buy a cheap test kit, know your feed water hardness. I changed mine to 5760 gallons before a regen is triggered. I am going to regen 6 times less than programmed setpoint. Using less salt and increasing the lifespan span of my resin. Loading less salt. Buying less salt. Win win win. We have a family of four in my home. After reviewing our summer water usage, of 7.5-10 thousand gallons. You can see I am going to regen my resin 1.7 times month while supervising my softener differential pressure. At stock setpoint, I would regen 10 times at max usage. Big difference. Purchasing a test kit is best as this will allow you to monitor your feed hardness by season. Sometimes, water companies will change feed sources or change their treatment regimen or chemicals. Changing your water profile. There are many variables to consider. Onto this softener. It's a fleck style head with somewhat fleck style controls. Quality is decent for a residential unit. The digital controls are convoluted and will require frequent reference to the user manual. However, the overall set up and operation is relatively simple. Upon install, I had 0 problems. No leaks and a successful Regen. After a 10 minute flush, I had 1 ppm hardness at my faucet. Down from 85.5ppm (5 grains per gallon) before softener. Plan to provide shelter for this softener as it should not be installed exposed to sun and rain. Keep in mind that if you install it indoors, which I considered, and there is a catastrophic failure causing a leak, you will flood your home if draining for such an event isn't considered. I will update this review with relevant pros and cons after more usage. Overall, this system gets the job done. Update 10/18/23- My feed water hardness changed to 8gpg. Leading to hard water before regeneration. After adjusting my gallonage setpoint, I will be fine. Best practice is to leave it this way for the near future and reassess. We have gone through drought conditions, temperature changes and then a high amount of rain. This can have affects on the surface water source and the treatment plant operations. The only issues I have with this softener so far are: -lost totalizer (counted) gallons if I enter the menu. This needs to be fixed by the manufacturer. -lost totalizer gallons during a power outage. This will lead to hard water as the count resets. This needs to be fixed by the manufacturer. -clock isn't accurate. I had to abandon time/throughput based regeneration and move to throughpit (meter gallons) only. This needs to be fixed by the manufacturer. If you are experiencing hard water issues before regeneration occurs, check your feed water hardness, meter regen setpoint and ensure your brine tank is running empty during regeneration step brine draw. Update 12/1/2024- I have been using this softener now for well over a year. Overall, I am satisfied with the product for the price. I always have soft water and I am continuing to check my feed water hardness periodically. As long as the control head continues to function correctly, I suspect I will get many years out of this softener and it's resin. Likely well beyond five years. Yesterday's feed water test (first in several months) was 7 grains per gallon. 32000 grains/7 grains=4,571 gallons. 4,571X.90=4,113 gallons for my metered regeneration setpoint. We do not want to utilize 100% of the capacity. So 90% is the desired number. Yesterday, I had soft water directly up until regeneration. Indicating the softener is performing as intended. For this softener, I recommend meter regeneration setting (throughput) only. The time based or meter/time based is not efficient or reliable. Until I have an issue with this softener, this will be my last update. ... show more

  • Great Water Softner System
Size: 48,000 Grain
We got this because our old Kenmore machine was having issues and needed to be replaced. It arrived quickly and without any damage. It was fairly easy to set up and install, though we had to pick up a few connections from the hardware store to make it compatible with our system. It works great, and we love the newer model. It's much more efficient and even saves us on salt! ... show more

  • Very nice unit
Size: 48,000 Grain
Works great. Easy to install, and I'm not a plumber, and I hate plumbing. Told myself, when ordering, I would give the installation a shot, and then most likely call a plumber. Didn't need the plumber and saved a lot of money.

  • A good Water Softener for the Money
Size: 48,000 Grain
The water softener once set up works great giving soft water to our home and regenerating when needed. You do need to have a water test done beforehand so that you know the hardness of your water. There is a calculation needed so you program the gallons between reigns correctly and your water hardness is needed for that calculation. The installation and programing was easy. Remember to follow the ending instruction on how to turn back on the water to the house with the bypass valves off at first. I goofed and turned on the water to the house before reading the final instructions and sent some residue through my house! My likes: Runs as expected, easy set up, good price point for what you get. My dislikes: No battery back up. So when the power goes off you will need to reset the time and possibly reprogram all the settings again. Could be solved by a simple 9v battery, but this unit does not have that. A continuous lit up display. These units are placed usually in utility closets that are dark so seeing the display is difficult. Finally the bypass valves stick way out and are held in place by a couple of metal clips and O rings for seals. Using 1" pipe this easily puts too much downward pressure on the O rings allowing a little drip. One has to be very careful in placing the unit so that the pipes can be attached to a wall so there is no pressure on valves. This works great until someone knocks the unit and it shifts a little then the anchored pipe puts pressure on the o-rings allowing a drip. I assume once I get all the walls built on my new utility room this will not be such an issue, but it is a poor design since the pipes are quite a few inches away from the o-ring joint placing a lot of torque on the joint. ... show more

  • I Love it.
Size: 40,000 Grains with Pre-Filter
This works really well and costs much less than stores. I paid a plumber $400 to put it in and asked him. He said they’re all pretty much the same. Showering is a pleasure - water feels really silky. Hope this helps.
