Well my first attempt ended badly. I slopped purple primer all down the inside of the pipe and I didnt know if the primer was supposed to be dry or wet when the cement was applied (didnt say in the instructions). I waited a little bit but when I applied the clear cement, a lot of the purple smeared where it wasnt dry yet.. Is that joint going to hold?

This is for my fish pond filter - pipe for water exiting back into the pond -and it would be disastrous it gave out. Also is that purple stuff inside the pipe going to leach out and poison my fish? Or let me rephrase that - if it was drinking water flowing through there would you consider the water safe to drink. Hopefully I'm just being paranoid but thought I would check it out with you all
