Dear All,
I have new hanse388, and it is the second time I found significant amount of water under the floor collecting mainly at storage for wine bottles but some also in the storage room under the couch. I have washed the boat today and filled up the water tank. Had minor usage of the the water system as well but much less than what I found. The service of the dealer tried to fix it couple of weeks ago ( seems like with no success). Rest of the boat is completely dry. Are you guys have any idea? Thank you in advance Laszlo Radvanyi

Do you have AC? Our condensation tank float stopped working and allowed water to overflow the collection tank under the floor and filled the stringers underneath.

Lazlo, this is the place where all the water ends up. Check the filling pipe of the fresh water tank and the seal of the flange. I ended up filling the tank only 90% instead of waiting for water coming our thru the tank vent. If you have a leak there you fill not only the tank but the stringer as well.
The second culprit could be the sink(s), check the elbow connections! Less likely would be the water heater, I ended up having a hose connected to the pressure valve. BTW a small oil change pump is most helpful sucking (most of ) the water from the stringer

I think most of us appear to have water loss from the pressure relief valve on the water heater. I had this valve replaced under warranty but it made little difference. I now have a hose attached to this running to a collection bottle in the engine compartment. This needs to be emptied a few times a season.
I have also had water leaking from the inspection hatch on the fresh water tank. This was my fault as I didn't tighten the cover sufficiently after the winter cleaning. I now use vaseline to ensure a watertight seal. Also check your stern shower is fully turned off. Does your water pump occasionally run momentarily when no taps are open? That may indicate a leak somewhere in the pressurised side of the water system. I don't get any water in the boat in rain or when washing the decks.

I have had a few problems with the fresh water system leaking, twice where hoses have blown off and pumped the tank into the bilge. The indicator is if the water pump surges occasionally when in standby.
Check around the pump / filter, I had loose hose clips here and pipe came off. Check SS braded hoses on back of cockpit show taps, I had one leak and kept finding water in bilge. In fact check all water pipe fittings and make sure crimp and clip connections are tight. Not had any problems now for a whole season, so finally sorted. It’s probably all down to settling in or maybe an apprentice was responsible for plumbing my boat. Happy sailing ⛵️😊

Hello Laszlo,
I have as well a new H388 and I am facing as you the same issue of the water under the floor in the same position. So far I checked a bit everywhere but have not found the main reason of the leak. I saw some water from the pressure valve of the water heater but I don't believe this is the main reason of the water under the floor . I also checked and the water pump do not run when taps are closed : so it cannot be a leak in the pressurised side of the water system. As Fendant suggest I will double check the filling pipe of the fresh water tank: if I discover something I let you know...

On our 418 we had some leakage from the fresh water inlet pipe to second water tank that accumulated in the bilge as you mentioned. Our dealer Insperation Marine soon fixed before we took delivery and not a problem since but the fresh water piping area would check out. Hope your enjoying your new boat.

At the handover check for our new H388 we noticed the connection to the plastic exhaust muffler (if that's what it's called) was leaking. A Hanse engineer replaced it with a new one. The replacement wasn't identical to the original but had a better connector design.

I had water collecting under the motor for a long time, which was driving my crazy ! After checking all hoses and valves, I finally found the culprit: there is an anti-siphon device installed in the saltwater circuit, just before the muffler. It is a valve from Vetus, in the shape of an inverted Y. When the motor is working, depending of sea conditions, it can leak trough a small hose. Changing the internals of this device did not help. According to the manufacturer, it WILL leak (having a hose to direct this leak to the bottom of the motor is, in my opinion, very stupid...). Anyway, I diverted this hose to the companionway door compartment. Problem solved, without much work...
