✓Fleck 2815 control valve by Pentair: 316 stainless steel body, 1-1/2 inch NPT inlet and outlet, digital controller
✓4 cubic feet of Katalox Light media by Watch Water, in separate bags, loaded into the tank at install
✓Ships by freight on a pallet, free to the lower 48 states
Not included
✕Drain tubing or pipe
✕The plumbing fittings and pipe to connect the filter (your plumber supplies them)
Every tank ships empty. The media goes in at install through the top of the tank, so the valve comes off for loading.
Who it is for
Sites with 1.5 inch plumbing: large homes with a 1.5 inch main, farms, irrigation wells, laundromats, restaurants and apartment buildings. Our residential iron filters all have 1 inch connections ("Everything we have is an inch," Aidan says), and this is the step up. In his words: "we go to a commercial size for like apartments and massive houses with inch and a half to two-inch plumbing."
Not the right fit
✕A home on 1 inch plumbing. Our residential iron filters use the Fleck 2510 AiQ air-injection valve with 1 inch connections, and they cost less (table below).
✕A well that cannot supply 20 to 25 GPM for the backwash. The backwash is how the filter flushes out the iron it has caught. The residential sizes need less: about 5 GPM for the 1.5 cu ft, up to 12 to 15 GPM for the 3.5 cu ft.
✕A room without the height. It stands about 75 inches tall with the valve, and the valve comes off the top to load the media.
✕Bacteria or hardness. It does not disinfect and it does not soften. A softener goes after the iron filter.
The Fleck 2815 valve can pass 70 GPM, but the Katalox Light bed decides how much water comes out clean. Watch Water designs Katalox Light filters at 8.2 GPM per square foot of bed and allows up to about 12. This tank's 16 inch bed is 1.4 square feet, so it treats about 11 GPM continuous and about 17 GPM at peak. Watch Water's own caution: "At higher flow rate filtration quality might be compromised."
If your steady demand runs higher, text Aidan your numbers. In his words: "Most customers with high demand applications use multiple units."
What your well has to supply
During the backwash, Aidan asks for 20 to 25 GPM from the well. Watch Water's backwash rate for this bed works out to 14 to 17 GPM for 10 to 15 minutes, plus a short rinse. Have your well pump's flow checked before you order.

What your plumber does
✓Connects the 1-1/2 inch NPT inlet and outlet.
✓Runs a drain line from the valve's 1-1/2 inch drain connection, sized for the backwash flow (drain tubing is not included).
✓Loads the 4 cubic feet of Katalox Light into the empty tank through the top, then puts the valve back on.
Space, pressure and water
Height with valve
About 75 inches (tank makers list a 16 x 65 tank at about 66 inches, and the valve adds 9 inches)
Tank diameter

Water pressure

Backwash supply

Check your ceiling height before you order: the valve comes off the top to load the media.
How it works
Water flows down through 4 cubic feet of Katalox Light. The media's manganese dioxide coating turns dissolved iron, manganese and hydrogen sulfide into particles, and the bed filters them out, along with sediment down to 3 microns. When the controller calls for a backwash, the valve reverses the flow and flushes what the bed caught to the drain. This unit has no air injection and no chemical feed. Aidan: "The commercial units don't come with air injection, but it's not necessary." See how an iron filter works.
What it removes, and what it does not
✓Iron, manganese and hydrogen sulfide (the rotten egg smell), and sediment down to 3 microns.
✓We size this unit from your water test rather than a printed ppm limit: send Aidan your iron, manganese and sulfur results.
✓Works best near pH 8. If yours is lower, send Aidan your test before you order.
It depends on how much water runs through it and how much iron is in it. In homes Aidan sees 6 to 8 years; Watch Water rates Katalox Light for 7 to 10. Write the install date on the tank, and when iron or the smell comes back, it is time for new media. The tank and valve stay.
Certifications and origin
Watch Water states that Katalox Light is certified to NSF/ANSI/CAN 61 for drinking water use and NSF/ANSI 372 for lead-free compliance; it is made in Germany. Pentair states that the Fleck 2815 is tested and certified by the WQA to NSF/ANSI/CAN 61 for material safety and NSF/ANSI 372 for lead-free compliance. These are the parts' certifications; there is no listing for the assembled filter.

At Watch Water's design rates the 16 inch bed treats about 11 GPM continuous and about 17 GPM at peak, and the backwash needs 20 to 25 GPM from your well. A home on 1 inch pipes is better served by one of our residential iron filters, from $2,095.
The tank ships empty by freight, free to the lower 48 states, with the media in separate bags that are loaded at install. We recommend installation by a licensed plumber, and Aidan supports your plumber by phone. Send Aidan your pipe size, flow and water test before you order.

Frequently Asked Questions
If your home has 1 inch pipes, a residential iron filter fits better and costs less: from the 1.5 cu ft for 1-2 bathrooms ($2,095) to the 3.5 cu ft for 5+ bathrooms ($3,295). This unit is for sites with 1.5 inch plumbing, such as large homes with a 1.5 inch main, farms, irrigation wells, laundromats, restaurants and apartment buildings, with a well that can supply 20 to 25 GPM for the backwash.
About 11 GPM continuous and about 17 GPM at peak. The Fleck 2815 valve alone can pass 70 GPM, but the Katalox Light bed sets the treated flow: Watch Water designs these filters at 8.2 GPM per square foot of bed and allows up to about 12, and this tank's 16 inch bed is 1.4 square feet. For higher steady demand, text Aidan your numbers; in his words, "Most customers with high demand applications use multiple units."
Aidan asks for 20 to 25 GPM from the well during the backwash. Watch Water's backwash rate for this bed works out to 14 to 17 GPM for 10 to 15 minutes, plus a short rinse. Have your well pump's flow checked before you order. Our residential sizes need less: about 5 GPM for the 1.5 cu ft, up to 12 to 15 GPM for the 3.5 cu ft.
No. This unit has no air injection and no chemical feed. The Katalox Light media's manganese dioxide coating turns dissolved iron, manganese and hydrogen sulfide into particles, and the bed filters them out. In Aidan's words: "The commercial units don't come with air injection, but it's not necessary."
We size this unit from your water test rather than a printed ppm limit; Watch Water prints no ppm ceiling for Katalox Light. Send Aidan your iron, manganese, sulfur and pH results. Works best near pH 8. If yours is lower, send Aidan your test before you order.
The 16 x 65 inch tank with the Fleck 2815 valve, and 4 cubic feet of Katalox Light in separate bags. Every tank ships empty; the media is loaded at install. Drain tubing, fittings and pipe are not included. We recommend installation by a licensed plumber; Aidan supports your plumber by phone at 800-460-5810.
About 75 inches tall with the valve: tank makers list a 16 x 65 tank at about 66 inches, and the Fleck 2815 sits 9 inches above it. It is 16 inches across. Check your ceiling height before you order, because the valve comes off the top to load the media.
It depends on how much water runs through it and how much iron is in it. In homes Aidan sees 6 to 8 years; Watch Water rates Katalox Light for 7 to 10. Write the install date on the tank; when iron or the smell comes back, it is time for new media. The tank and valve stay.

Commercial Iron Filter...$5,695.00
Why a commercial filter costs more
The price buys the 1.5 inch stainless valve and the bigger bed. A home on 1 inch pipes does not need them.
Is a residential filter enough?
For a home on 1 inch pipes, yes: our residential iron filters start at $2,095 (1.5 cu ft, 1-2 bathrooms) and go up to $3,295 (3.5 cu ft, 5+ bathrooms). This unit is for sites with 1.5 inch plumbing and a well that can supply 20 to 25 GPM for the backwash. Send Aidan your pipe size, flow and water test before you order.
