155 Genoa for Sale, Holding tank pump

B

bbfields

Bill Fields
I have a 155 genoa in good condition on a Harken roller
furling system for sale or will trade for a good 130-135
genoa.This is on a Morgan 384.
Also, I would like to have the capability of pumping my
holding tank when in appropriate waters. The one estimate I got
included a diaphram pump located under the galley sink and a
through-hull all for $1800. I'm not too happy about another hole
in the hull and the price seems high. Anyone have any experience
with this? Suggestions? (The current system has the option of
pumping to the tank or overboard).
 
John, $1800 is too much! I don't have a system for doing this, but I was told that placing a t-valve in the hose leading to the waste pumpout on deck, a macerator pump ($150) and a discharge thru-hull above the waterline would do the trick. Of course, you'll want the high quality rubber hose leading to the thru-hull. The pumps I have seen advertised empty a 30 gallon tank in three minutes. Oh yeh, the electric. So ... $500 should do it handsomely. The starboard hanging locker out all the way to the hull would accomodate everthing with lots of room to spare.
 
Thanks, Cary, for what seems like an idea with merit. I am looking for the simplest solution. The one issue that may be a problem is the height from the bottom of the holding tank to the top of an anti-siphon loop which might be 10 feet(?).That's why they proposed a diaphram pump.
 
I put a $50 hand pump under the nav-station--in the wet locker. I put a y valve in the pipe going to the deck, and I can pump out of the tank and overboard, when appropriate. I do not and never have had a macerator pump, but I do use holding tank treatment. I put a high quality through hull in the wet locker, 1 1/2 inch groco, which I bought used fo $25. Major expense was the haul out and the throughhull placement, which I should have done myself, but I had less time than money. Puttin in a through hull is very easy witha hole saw--just remember to epoxy a wood backing plate. I figure this cost me a couple of hundred, and if I had done the work on the hole myself, would have been $100. If you do this or something like it, please let me know how thick the hull is. My shipyard lost the plug, which I asked them to keep.
 
<div>1. You don't need an anti siphon since you will be openening and closing the valve as you need it. Open it, pump, then close it.2. How much for the 155? How old? What do you mean by good condition?My email is fcbob@cwix.com

Re your question about pumping the holding tank: I don't know that this has ever been done, but I have thought about it. If there were a "Y" valve connecting the holding tank pump out line and the manual bilge pump hose (both are in close proximity in the bilge), you could empty the holding tank using the cockpit pump. The cost would only be one each "Y" valve, a pvc wye, and 10,000 labor hours.
 
Add an 1 1/2" tee valve, located under the cabin sole, in the holding tank discharge line that goes to the deck fitting. A whale diaphragm pump, located under the galley sink, takes it's suction from that tee valve and discharges into another 1 1/2" tee valve located in the galley sink discharge line. The pump costs $135, the Y-Valves are $68 plus some 1 1/2" hose and hose clamps. A days work, some skinned knuckles and a few curse words and your ready to pump your stuff overboard.
 
Using the manual bilge pump to empty the holding tank via a Y-valve is a fairly creative idea. Unfortunately, I believe there will be a problem because any sewage remaining in the bilge suction hose will flow back into the bilge just as soon as the Y-valve handle is turned back to bilge pump position. There may not be much backflow, but in any amount it will be more than your nose wants.
 
Good point. A check valve would solve the backflow problem, but also the line should be flushed with fresh water, or sea water after each pumping. May be too much of a hassel if you have to do this on a regular basis.
 
A dedicated diaphragm pump under the galley, sink which pumps the holding tank out through the galley sink overboard via a Y-valve, would eliminate the backfeed into the bilge by using the cockpit bilge pump. Besides, we all know that the cockpit bilge pumps never work when you want then to.

 
Why pump sewage through a galley sink drain? I installed a separate thru-hull on the stbd. side with a macerator pump, or you use a valve and manual pump. You can then pump out from the shore or pump.
 
Thanks, guys, for all the ideas. It sounds like tapping into the existing pump out line would be the easiest solution.
 
Thanks guys, also, I just installed the macerator on the pump out hose in the wet locker and ran the output hose to a Y-valve off the galley sink.
It was a real pain getting the right fittings because of the 1" macerator output doesn't easily T into a 1.5". I have looked through 7 marine distributor catalogs for the right stuff. The job was easy once you have all the parts! Like most of our projects!!
Thanks again for all your comments and suggestions!

Using the galley sink drain avoids having to drill another hole in the hull. The Y-Valve in the holding tank discharge line allows you to have the tank pumped out from the deck or to pump it out overboard with the diaphragm pump.

 
I installed a diaphram pump in the locker under the aft port bench seat. I put in an access plate in the top of the holding tank for the just in case problem. Thru that access plate I made a fiber glass tube which became a new pump stanchon/ pipe (down to bottom of tank). I ran a hose from this pipe to the pump in the locker then ran the hose up the port side under the port settee following (parallel to the exsting head to holding tank hose). I then added a Y valve to the head dischage side. This then connects to the existing Y valve for the head. (holding tank or overboard). So when the two (2) y valves are set I can pump the holding tank overboard thru the existing head hull valve. NO additinoal hole in the hull and it keeps it out of the galley in a line that is not open to the atmoshpere to prevent any ordor.
I would like to know about your macerator pump. I tried a Jabsco macerator with little success. I mounted the pump just above the holding tank top to reduce the lift distance as much as possible. Still the pump didnot lift much, hence I went to the hand diaphram pump which has proven to have great lifting power and pressure for pumping over board. You can hear the rush of water/etc thru the hull at the hull valve while pumping in the main cabin.
Appreciate any ideas, I still have the macerator pump and would like the option of just flicking a switch and "away it goes".
