So ... hooked it up yet? Or still waiting on the metric PVC parts?
Man, that sounds sort of like a nuisance if you can't plumb it in without mail ordering pipe from somewhere
If not setup yet, maybe you can satisfy some of my curiousity nonetheless: How are you hooking it up? i.e. on the floor next to the sump? Does it have to sit higher than the sump water level? What kind of feed pump are you using?
