Sprayers Plus Bleach Sprayer

Worked great the first time I used it. Tried to use it today. When I tried to pump it bleach and water came spurting out around the pump handle. Ruined the pants I was wearing. Left if sitting when I went to change pants, when I came back the bleach and water was bubbling out of the top of the sprayer around the pump handle. Everything is secure and tight where it screws in. Comes out where the handle locks in. It is useless.
