Thank you. I already use all the capacity based on the the salt dose in the volume and type of resin being used. So where am I going wrong? Or how do you calculate this "increased capacity"?
Do you mean I should do the same as when I reduce the capacity by how much is used by a twin tank softener to regenerate either tank with soft water, but do that with the other type softener and then just say the twin tank has that much "increased capacity"?
If so, that would reduce the total lost capacity of the twin tank because it uses softened water to regenerate, right?
I guess you want to continue this discussion with more questions to the answers provided. I don't.
It is obvious that you don't agree with the benefits of regenerating with soft water. Therefore, it won't make a bit of difference to you how the questions are answered. It will just result in more questions. I'll defer to anyone else here who cares to respond.
I understand your point about the capacity really isn't being increased because you are using the capacity from one tank to clean the other... but twin alternating softeners cleary have benefits. The soft water regeneration is excellent at iron removal especially fine mesh resin. The soft water in the brine is also a great feature (some single tank models now do this).
The dual alternating valve enables an automatic no hard water bypass metered regeneration which is crucial when dealing with high iron. We all have the customers who claim.."I never use the water during its cleaning cycle."
Oh, and the extra capacity comes from the factory when the resin is manufactured... a twin tank softener has twice the capacity as a single tank, therefore the extra capacity is 2x that of a single vessel and will always be ahead of the single tank by that much....*scratches head*
