VanDiesel99 14 Report post Posted August 26, 2004 Recently purchased a "Power booster" so that I could link my two machines together to run my surface cleaner more efficiently. The power booster is basically two hoses with one way valves that merge into one out hose. I have a hot 4.8 GPM 3000 PSI and a cold 4.0 gpm 3000 PSI. The hot has a flow actuated unloader and the cold has a pressure actuated unloader. When I connect them and try to run the surface cleaner, the cold/pressure actuated machine kicks on but the hot/flow actuated machine never builds up pressure. Will putting a k7 flow actuated on the cold machine remedy this problem? I know it will work with two pressure actuated unloaders, but I won't be removing the k7 from the large machine. Any other suggestions would be appreciated, Thanks! Share this post Link to post Share on other sites
One Tough Pressure 580 Report post Posted August 26, 2004 If you do not have the correct size tips on the surface cleaner, the unloader on the hot machine will stay in bypass. Before you change anything, check the tips with a nozzle chart. http://www.arnorthamerica.com/spraynozzlechart.html Share this post Link to post Share on other sites
VanDiesel99 14 Report post Posted August 27, 2004 I never actually hooked it up to the surface claner because I didn't have the larger tips. What I did was use a very large oriface 0 degree tip that should have been more than both machines together could max out. I do see what your saying about the surface cleaner tips they would have to be rated for the 8.8 gpm it would theoretically would be pushing. I also tried it with a 80 degree size 11 tip that I had to try for roof cleaning. Share this post Link to post Share on other sites
Scott Stone 604 Report post Posted August 27, 2004 The flow actuated unloader is sensing the flow fromt he other machine, so it thinks it does not have to activate. Get another pressure unloader Share this post Link to post Share on other sites
