Rated 2 out of 5 by from somewhat disapointed Got the sprayer a couple weeks ago and have used it once. I used it to spray fruit trees, but it doesn't reach very high. I sprayed 3 gallons of spray and after each refill it took it longer to pressurize. The third gallon took a long time to build up to spray. when I rinsed the tank out and tried to run clean water through it the sprayer never did start pumping. I checked the pickup tube for clogs, but still not pumping.

Rated 5 out of 5 by from Well build machine I’ve been waiting for a replacement for the pump sprayers. Quiet with solid valve and quality brass nozzle for fine adjustment. Already bought another one for my son in law.
