An acid neutralizer will help bring your home's pH to a neutral 7.


This is how to properly install an acid neutralizer for your home. It will take approximately 2 hours to install a standard acid neutralizer.


When you receive your acid neutralizer, carefully unpack the contents of the boxes to make sure all package components are there.


Required Supplies:

  • Acid Neutralizer Tank
  • Calcite Media
  • CPVC Pipe
  • CPVC Fittings
  • Sharkbite Fittings
  • Oatey Pipe Glue


Required Tools:

  • Pipe Cutters
  • Large Pliers
  • Fill Funnel


Step 1: Find location for tank

Locate a spot next to your well tank where you plan on installing your acid neutralizer. Most basement floors are not level so you will need to adjust the tank by lifting the tank and tapping the edge of the black boot on the bottom of the tank in order to get the tank vertically level. 


Example: If you tap the back edge of the tank against the floor the tank body will move towards the wall.  The tank is designed to move in the black boot that supports the filter tank.




Step 2: Gather plumbing supplies 


Decide what type of pipe and fitting you will use to connect the neutralizer to your water supply. We recommend CPVC with Oatley 1 step glue or Pex with Sharkbite fittings or crimping tool.  CPVC is the cheapest way to go.


You will also need pipe cutters channel locks and a screwdriver and assorted fittings for the installation. All of what you will need is available at Lowes and Home Depot.




Step 3: Turn off water


Turn off the water supply before you cut into the plumbing. You may already have a shutoff valve after the well tank if so turn off the valve and open a cold water faucet to relieve the pressure.


Once the water stops, grab a 5-gallon bucket and your pipe cutters and remove a section of pipe after the well tank.


We typically start from the well tank with CPVC pipe and run all new piping to the acid neutralizer. If we have to reconnect to copper we do so using a sharkbite coupling in the size that matches the size of the plumbing which is typically 3/4' or 1". 


If you purchased a backwashing system you will need to install a drain line for the backwash discharge. This can be discharged into a sanitary tub an existing washing machine drain line sump pump or you may have to connect to your wastewater drain in the basement.  If you live in a warm climate year round, you can discharge the backwash outside.




Step 4: Add Calcite Media


Add the calcite to the tank using the fillport on the tank and the service funnel. If you received FloMag (corosex) with your order you will mix 2-3 pounds of FloMag (corosex) to every 50 lb bag of calcite mix well then add to the tank. 


Continue this process until the calcite level is 10-12 inches from the top of the tank.




Step 5: Turn on water  


Fill the acid neutralizer tank with water and pressurize the tank.


With a cold water faucet open and the bypass in the service position, slowly open your water supply valve a 1/4 of the way and slowly fill the neutralizer tank.  Once the water starts to flow from the cold water faucet, slowly open the water supply valve all the way and let the cold water run for 10-15 minutes to rinse the calcite media.   


Once you have completed installing your acid neutralizer check your plumbing and drain line for leaks and drips.  Once the water runs clear you can shut cold water faucet off. 


If you have a backwashing system initiate a manual regeneration cycle to purge any air and rinse the calcite media bed and check the drain line connections for leaks.




Step 6: Retest water


Retest the water to make sure you are at a neutral level. After your acid neutralizer has been in operation for a few days retest the water to make sure you are at a neutral level.  Home test kits are available at Lowes and Home Depot.

  • I have a Aqua-Pure AP101T now that is between the pressure tank and the acid neutralizer but I’ve seen several photos of setups on google that have the filter “after” the neutralizer then serving the house water lines from there. Can anyone help with info on the proper setup. Thanks
