## 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.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Programing the unit was an issue, but DYI info is on the internet for this unit.
*by J***K on June 5, 2025*

Expensive, but was easy to install.

### ⭐⭐⭐⭐⭐ 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).

### ⭐ Questionable condition
*by E***B on May 22, 2023*

Received package in rough shape. After opening, no packing material, parts looked almost used. Couldn't justify trying to install what might have been a defective $700 item that someone previously returned. Returned to amazon, bought on eBay, package was way better, obviously brandy new.
