Attention all Millennials: not all your problems can be solved by sitting back and pushing buttons on you phone or computer to access Google. At some point in life you may have to use those things that dangle below your torso, we call them legs.. you “could” use your legs to walk into a plumbing supplier and ask for a “Dickfour” cartridge adaptor, like I said… But If that offends you or you just can’t bring yourself to use your legs or you can’t leave your safe space then call, hire and pay a lic’ed plumber to solve your simple problem, and if you’re nice enough to the plumber they/he/she will help you to use your legs. [/QUOTE And here you are : sitting your much older butt behind a keyboard, commenting on a plumbing forum where the public can come to to seek insight…. Such a great response to a simple question to gain insight. Smh..
