Go to the hardware store and pick up the parts, 18 to 22 dollars.
Do it your self, takes about 15-20 minutes.
Save yourself about 85-100 dollars.
I used to be a Plumber, you are what I used to call a FISH.
You are what I would call rude.
Plumber is a family friend. He charges me parts and I feed him and the kids and let them swim.
