Hi,
I just replaced my kitchen sink faucet and it all works fine, except the sprayer can't be tightened enough - the base wiggles all around and you can lift it up - there is a huge gap. I assembled it before installing it in the sink to make sure there was only one way it would go together. There were no written directions, just an assembly drawing. I followed the directions step by step and there are no extra parts left over - but the sprayer assembly just won't tighten up enough. Any suggestions?

And you have all the parts?(see image).
Could the handle mount be cross threaded? Let me know, Tom

My husband helpfully showed me that I had put the plastic washer assembly on backwards, so I was able to fix it. Thanks!

Thanks for the update. If we can ever be of assistance in the future we're as close as a click. Cheers. TOM
