🔌 Function

Provides a manually controlled drain or isolation point so the connected fluid circuit can be serviced without disturbing unrelated components. Flush the connected circuit, confirm port orientation and calibration, renew seals and verify pressure/flow operation through a complete operating cycle.

⚠️ Common Signs of Failure

• Incorrect or unstable controlled temperature or fluid flow
• Flow remaining in the wrong circuit or failure to change mode
• Valve sticking, sluggish movement or incomplete travel
• External leakage or internal bypass across the valve
• Abnormal circuit pressure or alarms in the connected system

🛠️ Service Notes

• Have a container ready and drain the system down before removing the old tap; note what fluid the circuit holds and dispose of it properly
• Clean the threads in the housing and use a thread sealant suitable for the fluid and temperature involved, or the sealing washer specified for that fitting
• Do not over-tighten into a cast or aluminium housing — tighten enough to seal and no more, since a stripped drain thread turns a small job into a large one
• Confirm the tap opens fully and, more importantly, closes fully and holds dry before the boat goes back into service
• Work the tap open and closed occasionally in service so it does not seize, and renew a seized tap rather than forcing it
