I have made a recovery tank for my Prowler out of 2 plastic sealed 55 gallon drums hooked up to the pump out hose. I was wondering if this will be effective in the long term? It seems to work but I have not used it for very long. On the second drum I leave the cap off the second hole to exhaust it. Vacuum seems to be uneffected but wondering about any adverse effects to machine. The way I have it hooked is I run the discharge hose to first tank and than have a short section of 2 in hose running to second tank. I have not run it long enough to fill one tank completely and see if it flows into Second drum and how it will effect machine. Any thoughts on this are welcome.
