Well I have a Eheim 2215, and I just explained what happend to me on the worst experience thread, so know I need someones help that has used this before. I have put the line connetors with valves on them so I can switch them off (the green tubes) so water doesnt come gushing out, but the intake and output things pour water out too when i take the lines off for servicing the filter, how do I stop the water from comming out the valves when i detach the green lines?? PLEASE I NEED HELP, I think I made this thread a little too confusing so If you think you can help me just post clarify and I will do my best to calrify the situation.
