Roof Therapist 15 Report post Posted June 16, 2016 Can a simple water hose spray nozzle be used with a Delavan pump to water grass? I recently had some dozer work done away from any public water system. I have grass seed and straw down and need to water. Some of the ground is sloped so can't safely drive over with gravity flow system. I have a Delavan pump and 65 gallon water tank from my former roof cleaning business. Both have only had clean water inside. I have tried 4 different sprayers but can't produce enough spray to reach more than 10 feet. I sprayed for an hour and didn't empty the tank. Does a high pressure nozzle need to be on the end of a wand? When spraying roofs I had a trigger operated wand with a 4-nozzle head. It would spray much better. Unfortunately, I can't remember where I bought the wand online. Any ideas? Thanks, RT 1 ProCleanTampa.com reacted to this Share this post Link to post Share on other sites
ProCleanTampa.com 1 Report post Posted December 23, 2016 For roof cleaning ...try using a Soap Tip or pressure tip for a 8 gpm power washer fit your hose with a pvc handle with a ball valve and install a power washing quick connect at the end. Use those industrial tips to get more distance with the spray... In regards to watering the grass with a delavan pump I imagine you can rig the end of the roof cleaning hose to have a regular hose nozzle on it...... I once used my roof cleaning pump and set up to treat my yard for fleas that had gone insane and needed like five separate spraying's !!! hope that helped Share this post Link to post Share on other sites
