Can 2 sewer pipes from 2 rvs be connected to a dumping station or what would be the best method to connect 2 rv to a dumping sewer.

I am at a camp where there is a trailer hooked up to the main dumping station and was wondering if I could also connect to this main dumping station with a "y" is this possible.

I'd use a wye to tie both lines together, Good luck, Tom
