wagner 1420 sprayer not working

I have a basement to paint, and have a sprayer. It's a wagner 1420. However, it's not working. I can't get it to spray at all. It seems like it never reaches pressure, and not much ever comes out.

I have a couple questions:

1. Is this the right forum for this question? If not, please tell me where.

2. Are there some things I can try that'll help me understand what's going on with it. Is there a valve I need to close? I'd really like to try to figure out what's up with it, I don't really have the time to take it to the repair place.

I have a titon 440 airless that did the same thing. Turns out there is a check ball inside that needs to seal in order to build pressure. My sprayer just sat there churning away but wouldn't build pressure or stop churning. I took it in to SW and their repair center took it apart and cleaned everything out and repacked it for $150. Mine didn't have a lot of time on it and would sit for long periods of time without being used. I think that's worse for them than not using them.

Make sure your inlet filter and any other filters are clean. There should be a ball, it may be stuck. Sounds like its not priming fully. Make sure the inlet hose is clear inside of it. Some sprayer have a button to unstick the ball valve, check for that. Try running some thinner through it. Followed by water. It may be caked up with paint inside. Make sure to add the proper throat oil to it also, sometimes the oil will free it up too.

It's a wagner, so i'm not familiar with it, but on most professional pumps there is a metal part at the top of the syphon (the pump housing) that attaches to the body of the sprayer. Try hitting that with a hammer a couple of times while you've got the machine priming and see if it un-sticks the ball inside it. That is almost certainly the problem.

Never could get much production out of a Wagner. Usually we would just buy their cheap version and use it one time.......that's about all it was good for. Pain in the butt to clean up........
