Why is the capacity of my Runxin 63504 decreasing?
- C
  Cassie FrySep 12, 2025
  If the capacity of your Runxin Control Unit is decreasing, it could be because the unit fails to regenerate or doesn't regenerate properly; regenerate according to the correct operation requirements. A fouled resin bed can also cause this; increase the backwash flow rate and time, and clean or change the resin. Check if the salt setting is not proper and readjust the brine drawing time. If the softener setting is not proper, recount and reset according to the test of outlet water. Raw water quality deterioration can also lead to decreased capacity; regenerate the unit manually temporarily, then reset the regeneration cycle. Finally, a stuck turbine of the flow meter can be the cause; disassemble the flow meter and clean or replace the turbine.

What to do if Runxin 63504 softener fails to draw brine?
- R
  richard56Aug 27, 2025
  If your Runxin Control Unit softener isn't drawing brine, it could be due to several reasons. First, ensure that the line pressure is adequate; increase it if it's too low. Check for any blockages in the brine line and clean it if necessary. Inspect the brine line for leaks and replace it if needed. Also, the injector might be plugged, so clean or replace it. An internal control leak could also be the cause, requiring replacement of the valve body. Additionally, check if the drain line is plugged and clean the drain line flow control. Finally, ensure that the sizes of the injector and DLFC match the tank requirements according to the P20 requirements.

Why is there excessive water in the brine tank of my Runxin 63504 Control Unit?
- D
  danielle73Aug 28, 2025
  If there's excessive water in the brine tank of your Runxin Control Unit, it could be due to several reasons. The refilling time might be too long, so reset it to the correct duration. Check the brine line for any foreign material and clean it. Also, inspect the brine valve for foreign material and clean both the valve and the brine line. If a safety brine valve isn't installed and there's a power failure during salting, stop the water supply and restart, or install a safety brine valve in the salt tank. Lastly, the safety brine valve itself might be broken down, requiring repair or replacement.

Why is there pressure lost or iron in conditioned water with my Runxin Control Unit?
- S
  Sheila HoustonAug 31, 2025
  If you're experiencing pressure loss or iron in the conditioned water from your Runxin Control Unit, start by cleaning the water supply pipe if there's iron present. If there's an iron mass in the softener, clean the valve, add resin cleaning chemical, and increase the frequency of regeneration. For a fouled resin bed, check the backwash, brine draw, and brine tank refill, and increase the frequency of regeneration and backwash time. If there's too much iron in the raw water, iron removal equipment is required to install before softening.

Why is my Runxin Control Unit softener supplying hard water?
- D
  Daniel FrancisNov 20, 2025
  If your Runxin Control Unit softener is supplying hard water, several factors could be the cause. Check if the bypass valve is open or leaking and close or repair it. Ensure there is enough salt in the brine tank, maintaining the salt level above the water level. Inspect the injector for any blockages and clean or replace it if necessary. Also, verify that sufficient water is flowing into the brine tank by checking the brine tank refill time. Inspect the O-ring on the riser pipe for leaks and ensure the riser pipe isn't cracked, and check the tube pilot. If there's an internal valve leak, consider changing the valve body. Confirm that the regeneration cycles are correctly set in the program. Check for resin shortage and add resin to the mineral tank, looking for any resin leaks. Finally, b...

Why is there salt water in the softened water from my Runxin Control Unit?
- A
  Ashley MasseySep 9, 2025
  If you notice salt water in the softened water from your Runxin Control Unit, it could be due to foreign material in the injector or injector malfunction; clean and repair the injector. If the brine valve cannot be shut off, repair and clean it. Also, the rapid rinse time might be too short, so extend it.

Why is the brine interrupted or irregular in my Runxin Control Unit?
- M
  Mallory ParkerSep 6, 2025
  If you're experiencing interrupted or irregular brine in your Runxin Control Unit, it could be due to several reasons. Ensure that the water pressure is adequate and stable; increase it if it's too low. Check the injector for any blockages or faults and clean or replace it if necessary. Look for air in the resin tank and find the reason. Also, check for floccules in the resin tank during backwash and clean them.
