On the handle, remove the little blue cap, you will find a screw in there, that might help .Kids hanging on the faucet pulled the faucet off. There are female splines in the handle but the male splines on the sink side do not extend enough to engage. If I manually pull the plastic splines from the sink side, they will come up, but they won't stay up.
I think that the sink side needs to come off and then re-install the splines into the handle before re-attaching but I can't figure how exactly to do this. I tried wrenching on the sink side (not at the base but in the middle, the skinnier part) but it doesn't seem to want to budge.
Can anyone offer any suggestions on how to proceed?
I apologize for the reflective picture of myself
