I THINK I saw a post about this about 2 weeks ago, but for some reason I can't find it. Here's the situation. I had a nozzle start "clogging", or so I thought. I then took the "white" nozzle and put it where the "red" nozzle is, just the tip. That worked perfect, thereby assuming that the clogging was in the nozzle body itself, or somewhere up the line, between the nozzle body and the switch to go from "hi" to "low", since I get good flow out from where the red nozzle was, now with the white tip. Anyways, I spray again the beginning of this week, a late call to spray 6 parks. I get the first 3 done, no problems. The 4th one, started 2 days later, and the nozzle "clogs" up again. I pull everything apart with the hoses, clean it all out, and nope, no go. I then proceed to pull the entire "white" nozzle body off of the right side of the machine, the one that's working good, and put it on the left side. Works perfect. So, now I'm back to something clogging this nozzle body. I've got 2 new nozzles, including the bodies, so I put the entire new one on the right side, where I took the one from to replace the one on the left. It works for about 30 minutes, then..... drip drip drip...... like it's plugged again. In the meantime, the one on the left, still the original nozzle and body that came with the unit, although in a different location, is spraying just fine. If I shut the pump off, and then turn it back on, it'll pump fine out the right side for about 20 seconds, then just drip again, while the left side pumps fine. I ended up just shutting off the right side and spraying a 2 acre park with just the left side, trying to get these finished before I tear down the machine, possibly saving it for a winter project since this is the last job I'm sure I'll have. Anyways, my question, for those that have experienced pump failures, does this sound like something that you've had happen?? I have a hard time thinking my pump is going out, since I get good flow out of the left side. However, it's almost like the pump heats up and doesn't push enough fluid out, but if that's the case, then both should decrease in flow, not just the one. Any ideas???
