Water box overflow

I read an old thread somewhere about Hydramaster CDS water boxes overflowing when the float valve fails and it can flood the van and destroy the floor. Newer CDS 4.8 models have an overflow built in from the factory, I included a pic below.

Some have installed these themselves and plumbed it through the floor so excess water will just go out through that. But some say the overflow tube doesn't drain fast enough and water just overflows through the water box lid, or the pressure just blows the overflow off the side off the water box and it floods the van that way.

Have any of you experienced this and done a successful mod to prevent catastrophe? I'm thinking of installing an overflow with a sort of compression fitting that threads together from each side of the water box (sorry I don't know what it is called), with a larger diameter drain tube that I may have a local shop crimp together or something. So hopefully it doesn't blow the fitting off the side, and the water can drain out of the tube fast enough to keep up with the input from the garden hose...
