ALWAYS consult with Sanatoga Water Conditioning before self-service for proper procedures.

Neutralizer Service R 502

Read below to self-diagnose the problem OR call (484) 524-5802 to reach the technician on call.

  • Determine if water is being used in the house and if so, ask if it can be shut off or bypass the unit if possible. You may not want to do this in high iron situations.


  • Shut off water into and out of the unit.


  • Relieve the built-up pressure in the unit by placing the valve in backwash mode. Once the pressure is relieved, return the valve to normal service position.


  • Remove the access cap.


  • Measure the level of neutralizer material in the tank in relation to the top of the tank. Maximum fill height is typically 13-14” from the top.


  • Siphon out the appropriate amount of water to allow room to add neutralizer material. (Typically, about 2/3 of the volume of material you plan on adding.) For example, if you plan on adding a full bucket of R-502, siphon about 2/3 bucket of water out. Siphon off about ½”-1” of old neutralizer material as well.


  • Add neutralizer material to the desired level. (Typically, 13-14” from the top) Check as often as necessary with tape measure to get accurate level. Avoid overfilling as this will waste material and possibly clog drain lines.


  • Put valve into the backwash position again.


  • Open the inlet valve and fill the tank up to the level of the fill hole, close valve.


  • Return valve into the service position again.


  • Reinstall access cap.


  • Re-pressurize the unit.


  • If more than ¼ cuft of material has been added, allow 5 minutes for material to become saturated, and then put the unit into an immediate regeneration. If less than ¼ cuft has been added, set the unit to regenerate that night. This prevents the finer particles from working their way down into the tank and causing pressure drop.


  • Check timer and reset if necessary.


  • Close bypass valve, open outlet valve to restore water to the house.


Generally, 1 bag will add 3-4” in a 12 or 13” tank.


We offer 24 hour emergency service. Call (484) 524-5802 for the technician on call.
If you would like to bypass your equipment, please read below for step-by-step instructions. If successful, you’ll be able to schedule your service appointment in the normal schedule and save money.

Newer water softeners and acid neutralizers have the bypass built into the back of the control valve.

Below you will find instructions on how to operate your water valves in the event of an emergency.

Our dedication to our customers is continually rewarded with referrals and testimonials about our water quality solutions!

"Never disappoints! I've had two water tests conducted on my home. During the most recent John shared his knowledge and expertise on not only the Well tank pump that was in serious need of replacement but also options for my water softener. I never felt pressured to commit to something I didn't need. They made sure I had all the information and let me make a decision based on what made sense for me. Great experience from first call to final product!"

"We are new to the area and new to well water. We have used Sanatoga twice now - for routine maintenance and a water softener install. Juan is always on time and very attentive. We feel fortunate we have someone who cares about our house as if it were his own and a company we can count on in the years to come.
Thank you for excellent service!"

"We have used Sanatoga Water Conditioning as a residential client as well as for our business customers for several years now. I could not be more happy with the customer service and professionalism that they provide. I always get a cheerful and helpful person on the other end of the line when I call the office, and the technicians who installed our water treatment system were clean, professional and answered all of my questions. I can definitely recommend Sanatoga, 5 Stars."
