Review on Sierra International 18 4226 Drain Plug by Ricardo Knight

Worked great to replace a cracked connector on my 2007 boat. I was told that old boats had brass plugs that lasted a long time. It would be nice to find a replacement. I've read that these plastic plugs become brittle over time and they all need to be changed at the same time. I just made one and we'll see how the other one holds up.
