Joining PVC pipe without glue

I have a waterfall feature in my landscaping that I think has a leak in the discharge line from the pump. It goes up about 20 feet. I have laid a temporary 2" pvc line for a test, and I thought I could just duct tape the connectors as this is a high volume, low pressure pump (about 4000 gph). However, the joints leak. Is there a way I can make these connections not leak without using pvc cement as I want to remove the line after the test.

If it is just straight pipe, you could use rubber couplings (fernco couplings). But they will only work on pipe, not fittings. If you have fittings, you could glue in short stubs of straight pipe to allow use of rubber couplings.

But given cost of rubber couplings and pipe, you'd be better off gluing and then replacing the pipe later.

Another option is to use 2" pump hose for the test, but again, that will cost more than just replacing the pipe after the test.

you might be able to add some pipe dope to the joints but not sure it's going to work. Just glue it up and cut off the fittings, the pipe will still be usable.

Actually not Fernco couplings but PVC Dresser fittings.

Fittings are less than a buck apiece, Temp. fittings 4 or 5 dollars each, just glue it up and cut out the fitting when done.
