Hi,

Can some explain to me how to plumb my return external pump so that it can be removed for cleanings, etc? I have searched forever, and have come up with unions. What are those, how do they work?

Thanks

From what I have seen an union is a fitting that unscrews allowing you to break the con. You glue each end of the fitting to the pvc one going to the pump and the other side is going to the tank. It then bascically screws together having a seal on the inside so it doesn't leak. Hope this help don't really know how else to explain it. Maybe someone else will do better.
