Been thinking about building myself a homemade pump out since I only have a 50 gallon waste tank. Has anyone ever built one? I plan on doing this within the next 2 weeks, so any pointers or tips would be helpful! Thanks in advance.:hi::hi:

what do you want to build? 12V or 110V
Would like to build a 12v system and run it off of the van.


Why can't you some kind of a sub pump
Thought about the sub pump, but the guy from my local boat shop said the sub pump would not last very long. We have a ton of Agriculture shops around here, so I am gonna use a 12v pump of some kind and run it directly off of the waste tank with a 50-100' water hose. I would just like to know what GPM and PSI you guys would reccommend? Thanks

Farm supply would be a great resource. I got a diaphragm pump from them when my froze up. Great price, and I just bolted my 12V motor onto it, replumbed and I was back in business.

I have been looking at this one on Ebay. It uses the exact same pump set up as one sold on Jondon for about half the price of Jondons'. It looks pretty simple as it's just a metal housing with a screen, a cheap pump, float switch, and a screen to keep debris out of it. Here is the one on Ebay sold by Chemtex. http://cgi.ebay.com/ws/eBayISAPI.dl...3801266&ssPageName=STRK:MEWAX:IT#ht_720wt_939 and here is the one on Jondon. http://www.jondon.com/catalog/product_info.php?products_id=3216 . They appear to be basically identical. I looked up the pump that is used in both of them and it's fairly cheap and is 12v. That's called a bilge pump and can be bought in lots of places. Here is one very similar if not exactly the same. http://www.drillspot.com/products/67562/Rule_Industries_14_A_Bilge_Pump I think this is the replacement pump for the one sold by Jondon. http://www.jondon.com/catalog/product_info.php?products_id=7184
Cobb supply also sells an apo pretty reasonable that mounts externally. It is on the right side of this page a few items down. http://www.this company does not support TMF.com/tmacc.html

Thanks for ideas guys!

Randy, will look into that one on Ebay and see what I come up with.

Rickie, I'm really looking for a 12v system. I guess I could always run an inverter.

This might help you guys out

Hey guys. This is an item I use for our TMs I think ours is a 2.85 c.i. or bigger. The relative investment is costly Because of the Electric Clutch. The pumps are cheap.
The reason We use these Pumps. They Cycle off and on when needed and allow positive water flow against the negative pressures of the blowers. And triggered with electric float switch. The drawback is lots of mods.Get them From eBay or northern tool Its a Haldex hydraulic pump

Floorguy, I am just wondering how your project turned out?

I am very interested in build on myself, but I want to do it correctly. (float, check valve and filer)

Any feedback, pictures and parts list would be very HELPFUL!!!

Auto pump-out install finished.

I just finished my autopump out install into my Boxxer 421.

I installed a float switch and a relay between the float switch and the pump.

Had to build a turbulence shield around the float level switch. I used 1 PVC end cap and PVC fittings and tubing to connect it all together. You need to know the fitting sizes in order to adapt all of it but its pretty easy. I drilled holes in the bottom of the tubing so the tube drains when the tank is emptied.

It works great and pumps out 4 gallons per minute even with the motor at full throttle.

All I need now is the Filter.

Sure saves me a lot of time not running to the car wash to dump so I can finish the job.

Items List:

From Grainger:
Madison Item # 2XC13 Liquid Level Switch,Poly Float
Dayton Item # 1EHY8 Relay,Power,SPDT,12VDC,Coil Volts

From Dultimier:
Shurflo 4 gallon per minute Diaphragm Pump

From the hardware store:
Various brass fittings and a short garden hose to cut up
A ball shut off valve, install between the waste tank and the pump.

From the auto parts store:
Wire and Wire Terminal connectors

I really got tired of trying to build an inexpensive APO that would last. Finally broke down and got a Cleanco external APO
and love it. Took about an hour to install and works flawlessly. Downside is it's rather spendy, about $1700.00.
My supplier said they have been using it for three years with no failures.
Now I don't worry about filling up on a job, EVER! As far as I'm concerned, it was money well spent.

That is what I am afraid of... having it work all the time while under vacuum. But I am still trying to figure out why this APO is $1700-$1900. What makes it that much? My guess is there is only one made so the price will be high.
