What type of plastic? If it is styrene, there are many good solvent based adhesives that could work. It it is any type of polyethylene material, there is no adhesive that will work.
There are thousands of potential blends of plastic. Need more info.
What did they tell you at the pool store? (It was years ago, details now forgotten, but when I showed the pool store expert various parts disassembled from a filter, he told me two items were broken, i.e. ought to comprise a single unit: and recommended an appropriate adhesive: which worked.)

epoxy works underwater. but getting a clean surface to bond to might be a problem. gotta rough it up,too.maybe dril some holes for extra bonding surface. Can you unscrew or remove the broken part and glue it above water?
My pool store would send you home with a stick of 2 part epoxy paste, made for the purpose. It is also what the appliance repair store sells. The trick is getting it to bond. You really need to work it in to both surfaces well to expel the water. I fixed a skimmer once and it did work. Be sure you wipe the parts down well to get any surface oil scum off before you start. Scuffing it up with some 150 grit wet dry paper can help too. You usually just get one shot at this so preparation is everything.

Ideal for all types of household bonding and repair needs. It provides excellent adhesion to ceramics, china, glass, wood, concrete, metal and most plastics.
Unfortunately, they don't have anything whatsoever on their site that says it will work under water.
Their glue calculator, for example, to glue "plastic" to "plastic", simply comes up with:
"If you are gluing PVC plumbing pipes, we recommend: PVC Adhesive If you are gluing something else and your joint needs to be flexible use: Household Goop Otherwise, use: LePage's 5 Minute Epoxy or LePage's Regular Minute Epoxy"
devcon has a 2 part putty epoxy. available at home depot. i use it to attach corals to rocks in my salt water tanks. it cures underwater just fine, but it has to have some sort of mechanical lock, so you have to rough up the 2 surfaces well.
Well, the 'cannister' is a good foot below the base of the skimmer so I'd be pumping out thousands of gallons of water (maybe even a foot and a half below the base of the skimmer).
Yes, I could pump the water out (disabling the pool until I put 'back' thousands of gallons); but I was hoping for an underwater glue.
