This is the exact waterfall pipe and red cap used in the RAIN2. The Green Grabber screen is not included.
Note that the fit of the pipe into the black tray varies from pipe to pipe, and we test fit each one and adjust it for a final fit. So if you get this replacement pipe and it is too tight, you will need to sand or grind the pipe a bit, or the hole in the tray, for a looser fit. And if it is too loose, you will need to melt small marks into the pipe, or squeeze it out-of-round a bit, or use plumber's tape, for a tighter fit.
