Packing List
Fleck 2510 Backwash Control Valve + Pipe connector kit 1” + Top Basket
Neutralizer filter tank with Vortech distributor tube installed & Media funnel
Plus the filter media as follows:
For Calcite only types – use all the media supplied:
1.0 cubic foot size: Qty 2 50‐lb bags of Calcite
1.5 cubic foot size: Qty 3 50‐lb bags of Calcite
2.0 cubic foot size: Qty 3 50-lb bags of Calcite
2.5 cubic foot size: Qty 4 50‐lb bags of Calcite
For Neutralizer Blend 1.0 Cubic Foot: use 90 lbs Calcite and 10 lbs Corosex
Calcite 100 lbs (2 50‐lb boxes) 1.1 cu ft
Corosex (Also called Flo-Mag) 10 lbs (1 10 lb boxes) .13 cu ft
Don’t add all the media you receive: You do not want the tank to more than 2/3rds full, so generally we
recommend you add 90 lbs of Calcite (1.8 bags) and all 10 lbs of Corosex (or FloMag).
For Neutralizer Blend 1.5 Cubic Foot: use 150 lbs Calcite and 10lbs Corosex
Calcite 150 lbs (3 50‐lb boxes) 1.65 cu ft
Corosex (Also called Flo-mag) 10 lbs (1 10 lb boxes) .13 cu ft
Add all the media supplied.
For Neutralizer Blend 2.0 Cubic Foot: use 150 lbs Calcite and 20lbs Corosex

Fleck 2510 Neutralizer Installation & Startup Guide
Pre-Installation
1. Review your packing list and make sure you have received all the parts before beginning installation.
2. If you are going to be turning off the water to the house and you have an electric water heater, shut
off the power to the water heater before beginning installation in case water heater is accidentially
drained.
3. Pick a suitable location for your filter system on a dry level spot where it won’t be exposed to freezing
temperatures. A minimum of 20 PSI is required. Maximum pressure is 90 PSI.
4. Get all of your plumbing parts together before beginning installation. Installation typically takes 3 to
5 hours. However, after installation the system must be allowed to run through a complete backwash
and rinse cycle.
5. After the system is installed and running your water may be discolored or full of sediment/rust,
particularly if this is older or corroded piping. This typically clears up over a day or two.
Best Practices for Piping & Drain Installation
1. See typical installation (see Fig 2). The system is installed after the pressure tank.
2. Make sure to connect the IN pipe to the Fleck 2510 inlet and the OUT pipe to the outlet (see Fig 2). As
you face the Fleck 2510 control from the front, the water enters on the right and exits on the left.
From the back (see Fig 2) the water enters on the left. The inlet and outlet are attached to the bypass
valve which is marked with arrows as well.
3. Make sure there is a working gate or ball valve before the Fleck 2510 system and also one after as
shown in Fig 2. The pressure gauges are optional and perhaps not necessary but a hose bib (which is
a faucet that you can attach a garden hose to) is strongly recommended after the neutralizer filter
and before the second ball valve. This makes it easy to rinse your new filter on start-up and gives you
a place to test the water before it enters your household plumbing. It also makes it much easier to
perform maintenance in the future.
4. If you will be using copper piping, do not sweat the copper pipe directly on to the Fleck 2510 control
valve. Avoid heating up the Fleck 2510 control valve plastic with the torch.
5. If have copper pipe before the neutralizer and it is too difficult to change out, you may still experience
some copper staining of fixtures and have a copper residual in the water because this section of pipe
will still have acidic water flowing through it. We recommend PEX or PVC pipe up to the neutralizer
and then copper after it, if you have copper plumbing.
6. You do not need unions to install your Fleck 2510 control. If you need to remove it, the Fleck 2510
has quick-release couplings that make it easy to put the system on by-pass and remove the filter
system from the piping.

7. The drain line tubing (not supplied) is connected to a drain from the drain outlet using flexible ½” ID
tubing. Note that the drain can run up above the Fleck 2510 control and into a drain, it does not
have to drain down as the filter backwashes under line pressure from your well pump. Most plumbing
codes require an air-gap connection, so that if your sewer or septic tank backs up it cannot cross
connect with the drain tubing.
How Your Neutralizer Works
See Fig 1. In your neutralizer, the water enters the top of the tank and flows down through the media and up
the distributor tube. The downflow type neutralizer removes sediment and can be backwashed, which
cleans and re-classifies the Calcite, preventing channeling. During backwash, the water flow is reversed and
water flows down the distributor tube and up through the media, lifting and expanding the Calcite media.
During the backwash the Calcite is cleaned by the action of the water flowing through it.
