i have a chance to get a surface cleaner with vac at a great price and i was wondering if could connect it straight to a trash pump then into a tank?
is this possible?
Most likely no. Any trash pump I have ever used requires a good priming and a consistent load/flow. You need to think more in the direction of a shop vac. What size surface cleaner and what size pressure washer?
Check these, industrial style shop vacs. http://www.pressurewasher.net/vacuums . A high end home depot shop vac will work for point recovery, as in moving a puddle of water from corner of parkinglot to landscape but you will need more to effectively capture at the 21" surface cleaner. Whats your gpm?
