Adding a couple of comments... To add a window, you might replace the cap with a piece of 1/4" plexiglas acrylic sheet. It will bond with PVC cement just fine, I believe. To make it more secure, use a coupling for joining two pieces of pipe and cut the window to fit in the open socket, instead of just doing a butt joint directly to the end of the pipe.
You'll probably want to move the inlet and outlet fittings to the side of the pipe. That will keep you from having to put them through the window, which would weaken it, or the cleanout plug, which has to be removed using a wrench or pliers for servicing the unit. Be well, Mike D.
