    What water restrictions are in this valve besides the injector nozzle for the BRINE FILL and DRINE DRAW.

    Does the Rapid Rinse have a limiter ?

    Does the Backwash have a limiter ?

    Another thing, going by http://www.caitechnologies.com/images/PDFs/specs/SST60.pdf , the SST60 resin is superior in everyway to the regular 8% resins I can find the data for. --- more on this later

    Dont beleive everything you read in marketing literature. If that were the case, then salt free softeners would work better than traditional salt systems if I believed the marketing from a particular bird named unit that actually claims it makes "soft water" without salt.

    The Drain line Flow Control DLFC limits the water flow to the drain and is set at the factory. it can be replaced in the feild easily to meet the exact water conditions. Typically, the standard setting is adequate unless you have unusually cold or warm water. The fast rinse and backwash are both limited by this device. The Brine Line Flow control regulates the refill but not the brine draw or slow rinse. The brine draw and slow rinse is limited by the injector. Since the flow is slower than the DLFC, the DLFC does nothing to regulate the brine and slow rinse cycle.

    Hope this helps.

    LOL, had to edit this. I noticed one of the ads on this site is by the company I am commenting on. :)

    That is exactly the information I wanted yesterday.

    Do you know what the DLFC amount for the 3/4" 5600SXT is?


    And thanks for all the info.

    Just found this.

    Drain Line Flow Control Washers
    19151 -Washer Flow 1.0 gpm
    12085 -Washer Flow 1.2 gpm
    12086 -Washer Flow 1.5 gpm
    12087 -Washer Flow 2.0 gpm
    12088 -Washer Flow 2.4 gpm
    12089 -Washer Flow 3.0 gpm
    12090 -Washer Flow 3.5 gpm
    12091 -Washer Flow 4.0 gpm
    12092 -Washer Flow 5.0 gpm


    Wonder what I got. Crap, this is gonna affect how I do the settings. Why would you want to limit the backwash or Rapid Rinse?

    Gary Slusser That's all folks!

    The DLFC is based on the size of the tank and what media, like resin. A 2.0 cuft should have a 3.0.

    One reason is that if you don't control the flow of the backwash, you start backwashing resin out the tank...

    With the screens (I forget the correct name) in place, the resin could still get through it?

    The DLFC controls the expansion of the resin bed during backwash and limits the downflow, which will minimize waste. Unregulated system would waste a lot of water and the cleaning process would not be done. If you simply pushed the whole bed to the top of the tank and onto the top screen, the resin will not have expanded, it will have simply shifted. Resin bed expansion allows the resin to reclassify, to move around, and to be physically cleaned.

    As to the top screen, these are typically light duty screens, not intended for abuse. It is not unusual to see top screens collapse when a DLFC is done improperly. Please see the chart for proper expansion rates based on water temperature. We use generic charts for sizing DLFC's, but they should be adjusted for the application and for regional water temperatures. Of course a balance has to be made in areas where water temperatures vary regularly. Higher temperature requires more water to achieve the same bed expansion. Cold water uses less (the water is more dense, it cn lift more).

    Hope this helps.
