I have attached them to my system or aquariums by drilling holes in the lids. Just be sure to install a check valve so you can work with any setting with ease. I leave the valve closed when not in use so you don't have to worry about leaks if something breaks unattended. So far I open the valve to fill all the tanks at once in about 20 minutes with no leaks. Be sure to use Teflon tape. Thanks for a great product for the price.
