Connecting PVC to plastic?
What would be a good way to connect PVC to plastics?
Would the PVC glue melt the plastic? would silicone not adhere to the PVC?
Can't really explain what I'm trying to do (as it's a suprise...of sorts), but let's give an example that might help.
Lets say I have a rubbermaid bowl..and I'd like to turn it into a funnel, or sorts. This way water, pouring into the bowl, can drain out of a pipe at the bottom.
What would be a good way to do this?
I was thinking of just connecting PVC to a hole in the bottom of the bowl...but not sure what issues I'd run into with the seal/connection.
any help would be appreciated.

trial and error with a bunch of different advesives.  unfortunately PVC does not like to adhere to most normal adhesives. you can try cyanoacrylates. you will need a decent amount of surface area though to be sure of decent holding power. you can also try PVC cement, but that does not seem to work well on other plastics.
HTH,

It can be done with plumbers putty and a bulkhead. the roundness issue I am not sure about, but you can buy a bulkhead-like PVC fitting and connecti it to a rubbermaid tub and the fit the PVC to it. I have done that before to make a cheap sump with more volume.

Red lable Oatey multipurpose pvc/ppvp/plastic cement.
Most plumbing stores have it and it will work on almost any plastic and still be pressure rated if the fitting is made correctly, although I would test it a few times before making my final fittings.

maybe the blue lable glue for flex pvc as well if the fitting isn't so good. Use a lot of primer on the unknown plastic to get ti flexible and molded to the bottom fitting before gluing.
