DIY Pump out station?

[Top Shelf]

Searched the forums and didn't really find an answer. Has anyone ever done a mobile DIY pump out station?
Ie: plastic 50 gallon drum on a cart with a pump and the associated plumbing and connectors. And if so'
which pump did you use?

120vlt on the dock, seems like an easy project. I said "seems", but always defer to experience. Thx.

All the wheeled pumpout carts I’ve seen use Whale diaphragm pumps, as do some of the fixed facilities.

Self priming up to 10' it says...... https://www.campingworld.com/sealan...ps-plumbing/marine-sanitation/macerator-pumps

The Sealand is a great pump to install on board. It may work depending on the dock height. Typically it s about 6’ to 7 feet from the tank to the Gunwhale...

Some of the best pumps are made by Headhunters. They make waste transfer pumps although not cheap

I don't think he wanted an onboard pump. We got a gun-shy, so to speak, dock boy who got blasted and basted with a pressurized fecal fountain here some time back. Not sure how the boat's pump got energized but sure of the result. Better to pull than push, me thinks.

That s what I meant. The sealand maybe close to the limit priming from the dock especially if there is a small leak at the deck connection. A larger 120v pump maybe a better option

I have 120v Oberdorfer onboard pump , 1 hp , I believe they claim 10 ft of suction. It would probably work great on a dockside cart . It lists for about $1400 . It is for offshore discharge where allowed. As Robert mentioned, I would not like to try pumping out at the dock with it.

OK, the bigger question...once you get it into the “50 gallon drum on a cart” then what are going to do with it?

 

[jmooney]

This is a situation where over thinking never hurts.

When offshore I just turn on my Jabsco Macerator pump from the helm station and drain the holding tank via a pipe that discharges at the waterline starboard bow. I paid $115 for the pump and plumbed the line via a hull through. Easy.

The neighbors lawn.......no, no just kidding. We renovated our dock and pool area last year. I had a 3" waste line with a thread cap added.

I was contemplating doing the same thing this summer. I was going to use one of these: https://www.campingworld.com/barker...ank-32-gallon-100607.html?gclsrc=ds&gclsrc=ds .
And then set up an extractor vacuum motor (something like a ametek) on the top.

I am also interested in what others have done, dockside. May use my boat for guests to stay on at the dock. Would be nice to be able to pump from the holding tanks to a sewer clean out behind the house. I don't have an on board macerator at this time. With two holding tanks I think it will take a lot of plumbing, running 12 volt wiring on a 32 volt boat, etc. Would be easy for me, if I found the correct set up, to pump dockside into a clean out much like the marinas do

Not sure if 7' rise is enough.

You mean the SSK (Soviet state of Kalifornia) allows overboard dumping within 100nm of its shoreline? Wow, I m
Surprised ...

Seriously, one thing to watch out for with the cheap Jabsco is that it can’t run dry. Yeah they’re have the price of the sealand but the sealand is bullet proof.

Thats a good template for building my own but I sure don't want to hold that spring loaded switch down for it to pump 150 gallons of waste. Also 12 volts would require some rigging on my 32 V boat but not impossible. I would prefer a 110V model.

For some reason all I can imagine is a 55 gallon drum of kaka on wheels getting away from someone and going bouncing down the docks to it's inevitable $#itty demise like a scene from Caddyshack.

Sorry, but I just can't get it out of my head.

The cleanest, cheapest, easiest, alternative is to go to the local fuel dock and get pumped out. If nothing else, it gives you a reason to run the boat.
