All,
I've seen multiple complaints about the ryobi backpack sprayer. I've experienced multiple problems with it myself, but after two failed repair attempts by my local ryobi service center, I finally figured out the problem with my unit. There are two problems I had with my sprayer. I'll list each one below with pictures.
Problem 1 - pump never building up to full pressure despite pump always running. This problem was the easier of the two. There is a pressure adjustment screw on the bottom of the pump motor. I simply tightened this screw about 1 full turn and it was fixed.
Problem 2 - sprayer builds pressure but immediately loses pressure after the initial burst when you pull the trigger. This is the problem I initially couldn't figure out and even the repair center couldn't figure it out. I finally noticed a sharp bend in the hose between the tank and pump. It was kinked. I replaced it with a new piece of hose and made the new hose a little shorter to relieve the kink. This worked. It's still partially kinked so my plan is to insert a 90 degree hose barb with 2 straight pieces of hose.
