Title: missing part
Review: I have purchased several chapin sprayers over the years and always been pleased. This version was surprisingly less well built (ie, less sturdy). After simple assembly according to instructions, the sprayer worked fine for awhile and then the sprayer handle started falling off. I went back to the instructions and they showed a piece called the locking mechanism but said it was not on all models. This part was not on the handle I received and wasn't in the parts list. Fortunately this piece was on one of my older models so I put it on the new sprayer handle and the problem was solved. Called Chapin and they sent the part within a few days. Normally I would have written this off to an isolated packing problem but I also purchased the 2 gal version of the same sprayer with the same problem. If I wasn't familiar with the product design the sprayer would have been unuseable.
