The Turkish Bath Steam Generator on the Yacht Leaks Water from the Base or Cap

The steam generator of the Turkish bath on board a yacht is designed to operate in a sealed system, producing steam without leaks. However, when water is observed escaping from the base or from the generator cap, this issue can compromise both the correct operation of the Turkish bath and onboard safety. In this FAQ, we analyze the possible causes of these leaks and provide useful guidance to identify and resolve the problem safely and effectively.

 

Possible causes of water leaks from the generator

Water leaks from the Turkish bath generator can originate from various components or conditions that affect its proper operation. The most common causes include:

  • Worn or improperly closing drain valve: the valve may remain slightly open due to limescale, corrosion, or damaged seals.
  • Water inlet solenoid valve not closing: if it remains open, the generator continues to fill and water escapes from the overflow or cap.
  • Damaged internal seals: seals on flanges, caps, or drain connections may leak due to wear or yacht vibrations.
  • Excessive limescale in the boiling chamber: limescale can cause micro-cracks, overpressure, or distortions that lead to leaks.
  • Drain cap not tightened correctly: vibrations during navigation can cause it to loosen.
  • Cracked tank or boiler: rare, but possible in older or heavily worn generators.

 

How can I tell if the Turkish bath generator on a yacht is leaking?

A steam generator that is leaking water shows some easily recognizable signs on board the yacht. By carefully observing the cabin and the generator, it is possible to identify symptoms that indicate a leak and intervene promptly. The most common signs include:

  • Water droplets under the generator
  • Leakage from the cap or drain
  • Collection tray underneath filling up
  • Continuous “cycling” of the generator (repeated filling and emptying)
  • Limescale or hot water smell around the generator

 

Steps to identify leaks in the Turkish bath onboard

To identify any water leaks from the Turkish bath generator on board, it is important to perform some basic checks directly on the system. These inspections help determine whether the issue is caused by faulty components, limescale buildup, or malfunctioning drain or solenoid valves.

  1. Check the drain valve and ensure it closes completely.
  2. Verify whether the water inlet solenoid valve remains active even when it should not.
  3. Inspect the drain cap, tightening it only when the generator is switched off and fully cooled.
  4. Examine the generator for limescale buildup or deposits.
  5. Listen for water entering the system when the generator should be off.
  6. Check for persistent moisture even when the generator is cold, which indicates leaks or infiltration.

 

Practical solutions for leaks in the onboard Turkish bath

To resolve water leaks from the Turkish bath generator on board, it is important to intervene on the most critical components:

  • Replace or clean the drain valve to remove any limescale deposits.
  • Check the water inlet solenoid valve and replace it if it does not close properly.
  • Restore or replace seals on the cap and flanges.
  • Carry out professional descaling of the entire generator to remove limescale buildup.
  • If the tank is cracked, evaluate replacing the boiler or the entire generator.

In the meantime, until technical intervention is carried out, it is advisable to place a temporary collection container under the generator to prevent water from leaking and damaging the cabin or furnishings.
