The product worked great for my home made rain barrels

I use these as an overflow drain in my irrigated planters. They work great.

I'm trying to use these to connect blue barrels for rain collection. My plan was to attach a large, grey fitting to the side of each barrel, then connect those with the white fittings. It is extremely difficult to connect the grey fittings tight enough to stop leaks. Four of my six connections are leaky. This is just the nature of trying to get a water tight seal on a round surface. If you have two pipe wrenches to fit around the 2in nuts you will be alright. It won't happen with finger strength. The real pain is that there are simply not enough gaskets to seal the white fittings to the grey, and they do not sell this size gasket at hardware stores. You'll have to order double what you need just for the extra gaskets, as only the plugs come with that size on them, not the white connectors. The white connectors are guaranteed to leak without the extra gaskets no matter how tight you get them.

I would buy them again the Construction of them are top-notch
