Freshwater leakage

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Dear all,

I have a problem with leakage of freshwater (not salt). It ends up in the bilge under the sink. Since it is only fresh water I think it is leaking somewhere from the water pump. Has anyone experienced a similar problem and solved it? Where can I find the pump? Or what is the best way to tackle this problem?

Thnx,

Robert

PS: It is not the toilet since it is 'clean' water and it is not the shower since if we do not use it there is still leakage.

	Check all single handle faucets from the rear. They are pretty cheap. On my boat the mixing unit of the shower faucet was leaking behind the panel where it was mounted.

	1. check if the pump starts acting after some time without taking water from a faucet. 2. If so than there is a leak in the watersystem. On my boat it was several times the cockpitshower. But there are many possibilities for this. 3. If the pump does not restart without using water, than it could be rainwater aswell as condenswater from the fridge.

	Hi Robert, I found my leak coming from the faucet in the forward head. Also found the deck shower head leaking. Rich S/V Susie Q

	Shure that its freshwater? Or possibly rainwater? But my first controls would be freshwater as well. Check also the warmwater boiler if there is a leak.

	Thnx for all suggestions above. Elimination of options brings me to the following conclusions: - rainwater is out since it was 40 degrees hot and dry; - shower was not used; - don't have a forward head faucet; - cockpitshower was not used; Leaves: toilet, kitchen faucet or water pump in general. I emptied and dried everythingone evening and next morning was again lot of water. Only 'heavy usage' was of kitchen faucet and drainage so I assume problem has to be in pump in general or kitchen tap. How do I get to the pump? Kind regards, Robert

	If you use water you will hear your pump! If not, than you have a really good pump installed! In my 370 the pump is in under the shower seat in the toilet room. But i do not know if it is the same on the 400. BTW. You wrote: cockpitshower was not used. Did you check this shower? Mine lost a lot water without ever using it. BTW2: The first year i really was disappointed about this loud pump! I wanted a quieter pump. Now after more than 3 years, this loud pump saved me 2 times from flooding my boat! Both times i heared the pump starting to work without using any faucet. So i could stop the pump from working and searched for the problem. BTW3: I always turn of the pump when i am not inside the boat and at night aswell Edited by Peter-Blake - 18 July 2011 at 07:34

	I have had a similar problem. In my case it was the cockpit shower valve not being in the fully closed position, allowing a slow drip from the shower head into the bilge at the stern. As the shower head also has a valve on it, this is not always obvious. The area under the sink appears to be the lowest part of the boat so no matter where the leak initiates, it always seems to end up there. Mike

	I had a leak in the hose that runs from the water tank to the fresh water pump. The boat was new and the hose was probably punctured during some phase of the build. It did not leak enough to affect the pressurized fresh water system. The water would accumulate in the deepest part of the bilge under the sink. The solution was to run a new hose from the tank to the pump. Ed

	Hi I had internal leakage from faucet in galley, also there is a pressure valve on the isotherm hotwater tank that opens when pressure is too high, on this there are mounted a hose which leads to a bottle. otherwise the water goes directly to the bilge.... Pressure in hot water tank rises when potable water system is pressurized before the water is warm, when water is warmed up it expands and have to go somewhere. I changed the faucet in galley to a proper one and are going to change the others later.
