Most users only need to replace water hatches occasionally. Your software will show you warnings about the need to replace the water lock. If you don’t change it, the device will automatically turn off until you change it.
Water hatches have different lifespans. They prevent condensation from entering the device. Much more condensation can occur during exercise or sleep, requiring more frequent traps. Repeated use of the same test line will also shorten the life of the Trap.
Buy a Water Trap dryer if the separator change interval is too long.
