I sent off an email to ePlasics but figured I would ask here also. Has anyone used colored/transparent tubes in their plumbing? Anyone know if (for example) 1" PVC fitting would work with 1"OD tubes? The sump gets little/no light, so having transparent tubes 1)would look kinda cool and 2)would allow to visually monitor for buildup and any wayward/deviant "critters"....
