Cutting Holding tank access hole

The Jabsco Motor/pump is about 2.5-3 years old, if that.
Replaced just before I bought the tub 2 years ago.
No visible corrosion, wiring and power good.
Probably an impeller problem, lack of use: Guesstimating 3 minutes each pump, 10 pumps per year. Rotten impeller and internal corrosion, maybe.
No point in buying the cheapest macerator pump on the market, same problem over and over again.
Been replacing and even overhauling these $110 Jabsco pumps on client’s boats, not my fondest memories.
Would rather pay twice the price on my own boat for something that will last longer and work better.
Hopefully this Raritan will do just that.

The deck to holding tank hose could be collapsing under the suction. Have you investigated that area?

Took a quick peak in there, but did not really investigate.
I doubt this little impeller can create enough suction to collapse a proper sanitary hose, but I will take a closer look.

True.
Will do a Pump-Out Cruise tomorrow Friday to suck everything dry, rinse, repeat then some with liquid soap and more water and suction before I start tearing into the system replacing pumps and hoses.
Looking for friends and/or volunteers to help, We are all good buddies, stop by for a few minutes of manual labor doing hoses and hoses clamps with your face 6” from the affected area. I will of course supervise and the Coors Light is on me. Thx Guys.

Yup, will do, thx

Almost ready for installation of new pump and new plumping.
The surgery is being done through a small opening: Picture.
Took me 2 hours to get the old pump and hoses out and disconnected, laying flat on the belly with a flashlight strapped to the noggin and sweating like a 220 lbs pig.
Installation should be easier, 1/2 hour max..


Something to be said for bigger boats and more space..

They all look the same to me..

Just now realized I highjacked this thread.
My bad, Mea Culpa.
Should have started a brand new poo-poo-pump thread.
Next time.

Rub it in Bro..

Missing a double clamp on the inlet? There is also a soloution that uses bacteria to target the waste in the hoses. I think its a Raritan product? CO something....

I knew some eagle eye would see the single clamp..
That particular barb did not have enough real estate for a double SS clamp.
I tried and measured, but forcing 2 clamps on a shortie could do more harm than good.
Will look into the Raritan product you talk of...this one?

Yes I believe that's it. Let us know if it works as advertised if you use it ? My rairatian macerator has a rubber "nipple" on one end that you can slot a screw driver if it binds. I load mine with grease. Dunno if it helps....

Single clamp was only an observation on a hose that does not lead from below the water line - so I think that was me being me?

Not sure I need it.
You get calcium buildup in the hoses if not pumping enough. On my tub I counted 18 strokes minimum on the handle to empty the discharge hose.
Instructed guests and crew to do minimum 18, but bonus for 25 pumps.
(Learned that the hard way on previous boat. Calcium clogged up the hose and caused the famous exploding head..)
