Can anyone please tell me where the sensor is that activates the bilge alarm on our 385? Raising the float switch on the electric pump does not seem to trigger the alarm.

Hello, is your 385 equipped with a Yanmar engine ? If i am well informed they have a double seal at the saildrive with an alarm build in to warn you if the outer seal is leaking. Volvo does not have this double seal.

I do not believe that there is any alarm fitted to the electric bilge pump and I guess that if you add one it would also get triggered when running the pump manually from the main electric switch panel.
As other threads have pointed out, without a "sump" to collect water in the bilge, you can get a considerable amount of water in the bilges before the float switch is triggered. It has been suggested that the area below the galley sink might be the lowest accessible point. I also like the idea that someone came up with of adding a T-junction to the pipe for the shower and using a flexible (garden?) hose to suck out water from all those difficult to reach places.

AFAIK Hanse does not install a water alarm in the bilge. They rely on the float switch.
The problem is that water accumulates in the cavities formed by the stringers The culprits mentionned were the shower sump, the water heater and leaking faucets or leaking pipe joints. Special attention apparently should be geared towards the external shower. I have a grey water collector sump below the pantry, which is another cause for bilge water. Therefore I have installed a cheapo water sensor from www.conrad.de below this sump. In order to have a really dry bilge you need to get the water out of the stringers. For this we have used a small oil change piston pump with a 6 mm hose about 2-3 times / season. You need a small pipe dia in order to get all water out, a garden hose is way too big This year I have bought a little gear self priming pump with a small pipe inlet. I will try to move the watersensor into the Stringer, although I assume that this might trigger more alarms as necessary |

I have bought some of these water alarms from ebay: https://www.ebay.com/itm/382307424941 I have placed several places around my H400 to warn of any water in bilge. If you place one under the sink this is more or less the lowest point and it will get water if you get some in the bilge. I have bought a dedicated oil extractor to vacuumed out any water in bilge, but not used it yet. I also bought a
cheap endoscope for smartphone om ebay: https://www.ebay.com/itm/332249758637 Then you can really find out what is going on inside the
stingers if you are allergic against water in bilge as i am. |
