I just bought a Ryobi sprayer P/N P2803. It worked for about 20 minutes and quit building up pressure. Pump still runs but fluid only dribbles out, no pressure. Took everything apart and cleaned it. Tried a different known good battery. All to no avail. Still doesn’t work. I’ll return it, but that’s inconvenient. Any ideas what’s up?
