Anecdotal, but it was true for the company I worked for. Used to make ten brands of sump hose - the only difference was the bag we put it in and which fittings were included. The material, molds, and specs never varied.

I was thinking about this game yesterday and for the life of me couldn’t remember the name. Thanks!

Mine’s the same age and it’s almost unbelievable how almost everything needs replaced at 30 years. Roof, furnace, well pump have been done, a long with some faucets and other small things. I’m terrified the fridge, stove, and washer and dryer are next. Can’t afford much more!
