11 WATER SYSTEMS
11.1 GENERAL POINTS
- It is essential to rinse the entire on-board water system the first time the boat is used (The
water system is protected in the factory by a dietary anti-freeze).
- The water tanks may have had an anti-algae treatment using a copper sulphate based
product. It is advisable to renew the treatment according to the area in which the boat is sailing.
- Drain all the water systems during winterisation (in particular the cockpit shower and water
heater) to avoid damage from freezing.
- Clean/change the filters regularly.
- Regularly check water-tightness of joints in the water system installations.
Check that screws and bolts are well tightened and replace them if they are
worn or corroded.
- Disconnect shore water supply before leaving the boat (if fitted).
- If the boat is sailing in temperatures below freezing, it is possible to use anti-
freeze in the water systems: use a non-toxic anti-freeze marked for dietary use.
NEVER USE AUTOMOBILE ANTI-FREEZE: RISK OF POISONING.
