## Description

Fleck 9100 SXT Digital valve for water softener control valve dual tank replacement head - Household Rough Plumbing Valves - desertcart.com

Review: Great replacement valve!! - Replaced a cable driven Fleck dual tank valve. Went with the digital as the last Fleck cable driven gears stripped and the cost of replacing the part was just not worth it. This new one has much less moving parts. Easy install for a do it yourself person. You need to know your water details, I.E. iron, minerals etc in order to program it. I took a sample to a local water treatment store and for a minimal charge got all info I needed to program that replacement valve. I have been using this since March and so far it works great. With the last valve I was rinsing every 2000 gallons as that was the max I could set it for. with my tanks sizes and whats is in my well water I need to be rinsed every 3500 gallons, again knowing what is in your water helps on programing. I am now using way less for the rinse. Everything is working great after 9 months.
Review: Overpriced, outdated product - Received the Flexk 9100 SXT and installed, pressurized the system and then it began to leak, took it all apart only to realize it did not have a main seal for tank one. Took the old seal off my last system and then re assembled. Going through the setup instructions are basic, the config panel and setup are straight out of 1988. The setup functionality is not consistent, or it trys to run while going through the setup. No wifi or blue tooth which you would expect at this price. This is an OVER PRICED two tank system, this market deserves a better product. I can buy MacBook for this price, this is a system running on 1990 tech

## Questions & Answers

**Q: Will the Fleck 9100 sxt twin work as a backwash iron filter?**
A: No, not in most cases, it can only be set as a softener valve and most likely cannot provide enough flow rate for the backwash needed on most iron filter media.  If your iron is not too high, you can use this on a dual tank iron pro system using fine mesh softening resin

**Q: I have a 9000 Fleck that a small piece of plastic broke from the main housing that holds one of the gears.  Will the 9100 SXT replace the 9000?**
A: Yes, they use the same tank connections and same bypass valve connections.  There may be some difference on the pipe connections between the tanks, but it should work fine from what I have seen on those.  Worse case, you can replace the parts between the tank for $38.00 if needed by calling us.

**Q: what size injector and BLFC does this come with?**
A: You can specify what size you want when you place an order. Send a message, contact the seller right when the order is placed

**Q: You stated that using an old stainless bypass is not acceptable, is a new stainless bypass alright, or do I need to purchase a plastic one?**
A: The bypass valves typically used have a rubber diaphragm that breaks down over time. Either use a new one when replacing the control valve or better yet use the old fashioned 3 valve arrangement (I use ball valves) and the problem of rubber breaking down and contaminating your system goes away.

### ⭐⭐⭐⭐⭐ Great replacement for a Fleck 9100 valve
*by M***K on June 11, 2018*

I replaced a mechanical Fleck 9100 valve with this electronic Fleck 9100 SXT version. It has been working great. One key to successfully setting the valve parameters in the settings menu is to know the resin capacity of your tanks in grains and take 75% of that as the value entered, or alternatively, increase the hardness setting by 1.25. Another very important key is to know that water holds 3 lbs of salt per gallon - knowing this and the flow rate of the brine injector (0.5 gpm for the valve I'm using) you can set the number of minutes needed for the brine water refill (called "BF" in the settings for brine fill) so that you use the right amount of salt needed to regenerate the tanks based on the resin capacity and don't waste salt. There is little documentation out there on how to do this, however, the directions for the older style mechanical 9100 valve gives some good clues. There are a number of websites to get the recommended pounds of salt for regeneration based on the resin capacity of the tanks however. If you run out of soft water before the unit regens because your water is harder than you thought or your resin bed is somewhat depleted, just raise the hardness setting to regen sooner, or increase the minutes for BF (however, this is generally a less salt efficient way to do it).
