I recently moved into a home which has an acid neutralizer installed. It is a 1-NF Hague Neutralizer. Can you instruct me as to how I can add the filter medium to the neutralizer?
The process of adding filter media to your neutralizer tank may differ a bit depending on what type of tank you have. Adding filter media to a backwashing (downflow) neutralizer is different than adding media to an upflow neutralizer, and is further differentiated by the presence or lack of a top fill plug on either type of tank.
Since your neutralizer is a backwashing neutralizer with a top fill plug, adding filter media should be rather easy - simply follow the steps below:
Check pH before and after neutralizer periodically. A pH of less than 7.0 pH is acidic and a range of 7.2 to 8.0 is best for preventing corrosion of pipe and fixtures. Once or twice a year, depending on pH levels, add more calcite media to the neutralizer filter as follows:
1. Begin by putting neutralizer filter on bypass, or turning the water pressure off before the neutralizer.
2. Initiate a manual backwash cycle. Since it is on bypass, this will relieve the pressure inside the control valve so you can safely unscrew the media fill plug located on top of the neutralizer tank. Unplug the control valve cord from the wall outlet.
3. Unscrew the media fill plug with a channel locks or pliers and, using a tube or hose, syphon 2 to 3 gallons of water out of the filter tank. If you don't syphon water out, water will flow out of the fill plug hole and onto the floor when you add your media. If water on the floor is OK then you do not have to syphon water out first before pouring calcite media into top fill plug hole.
4. Add neutralizer filter media until the tank is 2/3 full. Do not over-fill: be sure to leave at least 12" of free space above media to allow room for the media to expand during a backwash.
5. Plug the control valve back in, and slowly turn the bypass valve back to the service position (if it’s in "service" this means it’s in the proper position for filtering and neutralizing). Allow the system to go through a complete backwash and rinse cycle. Repeat backwash cycle by starting another manual cycle, so the neutralizer is thoroughly backwashed and rinsed before putting it back into service.
