Re: Fresh Water Pump

gallivantbob <bobh@...>
 

Ian,
Last year I had a similar challenge to get the pressure up to the cut off point. Adjusting the switch as suggest is necessary, BUT I found that after a storage period there was a build up of rust colored gunk in the little pipe that the pressure switch sits on, which prevented the switch from sensing the correct pressure. After disassembling and cleaning the small tee and pipe, all was well.

couple of times now I have forgotten to trip the pump CB last thing at
night leading to a massive discharge of the batteries after the pump
failed to reach cut off pressure.

Looking at the impeller there does not seem much that can wear, but
maybe changing it will result in more pressure? Has anyone replaced this
impeller with a noticeable improvement please?

Because letters can be different sizes I am looking for the horizontal measurement of the space available in inches for the first line (name) and second line (hailing port). Centimeters will work also!

Thanks Craig,
Very timely article. I think Id like to be able to go to depths of 25-35 ft to allow retrieval of a fouled anchor. I'll do some more research and let you know what I come up with.

Somehow I don't think that solution would have ever occurred to me, Danny...Glad you took pictures so the rest of us will know what to do in a similar situation (~;
Then again, I might heave to and drop over the side head up instead.

knots at the time and didn't want to lose time by heaving to so with a

thanks for this. I have a higher output pump (as an optional extra)

envisage no problems if I purchase a new impeller.

One of the good points in the design is that the deck fitting and the

Hi to all and tank so much to all,
Problem solved !
- it was possible, as suggested, to insert up-down a long stick through the
deck hole into the full tank. I used the spear gun rod, I'm a very bad
underwater fisherman. so I found a new use for it . I felt with the tip that
the white tube was free ( the skin inside was smooth) up to the valve. So
the block had to be through the valve or between this and the sea exit.
- from the top side I used a "L " hard wire to check and to have the
connection free up to the valve from outside hole.
- little by little something came out and than the block dissolved !
- than I poured 3 lt vinegar to fill the column, with valve closed, to
better have it cleaned.
Thanks again and Buon Vento !

Re: [Amel] Re: rear holding tank clogged

Ann-Sofie Svanberg <kanalmamman@...>
 

Hydrochloric acid works perfect, but it affects the mercerator electrical motor. We used to use hydrocloric acid, but after destroying two engins we don't put the acid in the toilet any moore. If it is the tank that has clogged, put the acid in the tank from deck. But you need to leave the acid there for maybe one hour. The tank is made of GRP, so the acid doesn't affect that. And when the clogg is gone, the acid will pour out, as long as you leave the valve open. Rince thoroughly with water.

Or use vinaigre through the toilet instead. It does the same work, but needs longer time. Use 2-3 liters or more, leave it over night and then try to empty your tank. Repeat until the tank is clear.
This way you get both the tank and the hoses clean in the same time.

When you have (or if) you remove the lid to the tank you can also use some long stick to get the opening wider. The evacuation hole is mor or less straight under the deck hole.

Ciao Gianni,

I do not know if this was the correct thing to do...BUT...I used a form of acid that was some solution of Hydrochloric acid on BeBe's aft tank valve. I poured it in the deck pump-out opening, let it sit for about 15-20 seconds, then worked the valve handle back and forth. I repeated twice, then flushed with baking soda and water solution to neutralize the acid. I believe once you get it working freely you may be able to pump some lithium grease into the valve to lubricate it.

If your tank is full, you will have to have it pumped out before you try above.

Hope this helps.

Hi to all, I remember that some used to pour acid into the tank to dissolve the organic obstruction. But I don't remeber which, from which hole and how to work. Please, any suggestion may help.
All the best

Per Kent's comment that many of these systems are much too expensive for what you actually get, take a look at David Lynn's article in the December 2012 issue of Ocean Navigator about how to simply and cheaply construct your own.
