FLORIN 21 Report post Posted June 2, 2007 Just bought a used Landa hot water unit and am trying to work out the bugs before putting it in service. I am trying to downstream but am getting soap draw even with a 15degree tip. I have been having to go to the machine and turn off the soap valve that it has on the machine. my wand is the type that has two triggers, one for high pressure and one more forward on the wand for soap. On the the business end of the wand it has duall tubes, one for high pressure and one for the soap tip that does not come off. Any help would be greatly apreciated. I hope it all makes sense what i have written above. Share this post Link to post Share on other sites
Russ Johnson 141 Report post Posted June 2, 2007 If you're shutting off the valve on the panel to stop soap,you're upstreaming the soap, and the only way to shut it off is at the panel. The dual lance wand would be used to control a downstream injector, which should be mounted in the outlet of your coil. Share this post Link to post Share on other sites
