  • Capacity of a Water Softener How many gallons a softener will approximately make depends on the hardness of the water source and your water usage. To figure out the approximate capacity of your unit, take the grains of the unit (Standard 8,000/Double 16,000) and divide that by the grains per gallon (GPG) of the water source. Double Standard Softener 16,000 / 11 GPG = 1,454 gallons 16,000 / 58 GPG= 275 gallons

  • Easy to use with peace of mind
Bought this for our 5th wheel and not sorry at all. Works great at every camp site. Easy to hook up and remove.

  • So glad I took a chance on this!
Update: Well after 3 months with this, its getting to be too much to regenerate. Now it only lasts a day after regen. I don't blame the softener, it wasn't meant for this level of hard water. I still recommend as it does work, but again, for water that's not quite so hard. Original post: I live in a double wide trailer with, according to the maps showing hard water levels, the some of the hardest water in the states sitting around 39 gpg. I was dubious about living in a larger space than what this softener was meant for, but since it's only my dog and I, I went ahead and bought it. This little guy is surprising! I do have to regenerate it often because the water is just so impossibly hard here, but let me note I am not stingy with water, I clean a lot and like decently long showers :) I also have to buy bottled water to drink, this water is still not consumable. The softener is a bit heavy to turn on it's head to drain and lug around, but to get decently soft water, I really can't complain! I say decently soft because after regenerating it I seem to only be able to get it down to about 3 gpg, and that lasts for maybe a week. It's not ideal, but it's better than 39 gpg! ... show more

  • Works great
It does the job to soften the water without bad taste. You can buy some water Ph test strips and test your water to see how hard or soft it is. Florida has hard water. Hard water causes Build up of scale and minerals on pots, pipes, in plastic holding tanks, in water heaters and scale spots on shower doors, stainless/chrome fixtures and sink. Soap doesn’t lather up or feels like it’s not coming off. Great in our RV. With two of us, no washer, regular showers and water use about 30-45 days between regeneration cycles. Our water was extra hard but within a week it was way down in ph and softer. Better yet the regeneration of softener only takes 2 boxes of regular table salt to regenerate the softener every 30 to 45 days. Just use test strip to keep up with softness. ... show more

  • Great system and easy to set up
I have been very pleased with the quality of soft water - taste is excellent and skin and hair feel so much better!

  • Still happy after 3+ years
I bought this for my boat after I had new black water lines installed. The soft water helps to prevent build up inside the tank and lines. I recharge about every 3 months. I do have a whole house filter on the line before the water softener and I think that helps extend the time between recharges. One of the brass nuts has become stuck to the hose but other than that, it's been great. Would purchase again. ... show more
