Mixed bed softener setup

[Cjorg]

Hello all,
This is my first post, reading and learning a lot. Thanks to everyone for the informative info.
I have a 40,000 grain mixed bed (Anion) Fleck 5600 metered system that I'm rebuilding the valve, it came with my house, 4 people in the household. I live in Las Vegas, 18 grains of hardness and no iron. I'm wondering what the true capacity of this system is and if mixed bed is even necessary. Should I dump and replace resin or just run it. System is 8 years old.

Thanks

Are you on city water? If not, what is the purpose of the mixed bed? There are only 2 things that I of know of that a residential customer would need anion resin for, tannin and nitrates. I should have looked at the water report to tell you are on city water. I didn't see anything that I thought would need anion resin. But maybe they know something I don't.

Get a Hach 5-B softness test, and measure if the softener is giving 1 grain or less of hardness. If so, keep the resin.

If you change resin, I would go to a 10% crosslinked regular cation resin unless you have a reason to do otherwise.

Anion resins are commonly used for tannins, nitrates, sulfates, pH control (dealkalizing), uranium and much more in well water applications. This is not commonly done on municipal supplies.
If you are rebidding, I would probably just go with a cation resin only. Many of the mixed bed systems are done for marketing purposes rather than functional.

Wow, thanks for the fast replies. I was thinking the same thing about the anion resin, it was a way to get more money out of the customer as its not needed in Las Vegas city water. Good idea about checking softness for a while and monitor how long it stays soft. Seems that it should stay soft for 5-6 days before starting to get hard.

Forgot to ask, if I replace resin, is there a certain brand that I should look for. And what is the difference between 8% and 10% crosslinked?

 

[ditttohead]

10% is a stronger resin that is ideal for use in chlorinated water supplies. 8% is slightly less expensive and is acceptable in very low level chlorinated water supplies with low water use. As to the manufacturer, be sure it is purchased from a reputable company. I know of several companies in Vegas that stock high quality 10% resin. Let me know if you want a recommendation.
