  If your A.R.I. Control Unit valve is continuously leaking, first check the line pressure to ensure it's at least 0.2 bar (3 psi) for a tight seal. Consider whether the valve is connected to a booster pump or installed level with the water level in a tank, which could prevent proper sealing. Additionally, perform the steps for BASIC MAINTENANCE to address potential debris lodged in the seal or O-rings.

  If your A.R.I. Control Unit valve leaks from the threads, the issue could be a damaged O-ring or stripped plastic threads. Try replacing the Base O-ring and check for cross-threading. If the threads are stripped, replace the Base. You might also consider replacing it with a metal Base.
