My truckmount dont have this just wonder is any way to make your own pump out system or somebody have one used for sell thanks
Although it would be possible to build one there are some that I know of that are fairly cheap compared to the really expensive ones. Here is the one I may buy at some point, but I don't have a real need for one on most of my jobs. http://cgi.ebay.com/ws/eBayISAPI.dl...7003572&ssPageName=STRK:MEWAX:IT#ht_939wt_756 This one fits down inside your waste tank. The pump you will see inside it is the exact same one as this one at Jondon. http://www.jondon.com/catalog/produ...=3216&osCsid=0be9ef85beb4bb063a07ba7367468861 You can see they are made similar with the same pump. Only the outer housing is different. The pump that is in both of them is a standard bilge pump which can be bought pretty cheaply online. Maybe this can give you some idea of what to do. APO's must be either put inside the tank like this one or put outside the tank like the very expensive ones. I'm pretty sure this will fit inside most waste tanks, but you may want to check to make sure it will fit.
I have a little setup I put together that is relatively inexpensive (< $250), reliable and portable. Its just not automatic. In short it utilizes a Pelican 1430 toploading hardcase and a Little Giant sump pump a couple of 2"threaded PVC elbows and a bulkhead fitting. I use it by hooking up a short hose to the drain line of my recovery tank. I open the valve to drain it into the case and the sump pump is connected via 50 ft of garden hose to the cleanout of my sewer line. It works great It does need a filtering solution to help keep debris from stopping up the pump screen. But with very little maintenance it is a viable economical solution. The Pelican case is very very sturdy and is o-ring sealed and has a carry handle. The unit is portable and could be used as a manual pumpout on location. You just need to stop and go out, hookup and empty the recovery tank into it. I also installed the diaphram switch to control its turning off and on. I originally built this system to be an inline pumpout and while the case would hold 15+" of lift the challenge was how to pumpout against the vacuum. I got that resolved but the case was too narrow such that the vacuum hose could move and knock it over on its side. But it works great for my application right now. If you duplicate this design be careful in that the LG pump puts out something like 30 gal/min. That is enough if the hose were run inside to a sink or toilet that it could jump out and create a huge problem for you. The solution is to have a valve to recirculate the flow back into the Pelican case this acts as a throttle for the output flow. So for what its worth here was my solution.
