Lol! Let’s have a battle of ADHD blockades on this. I have forgotten for over a week to check the website well forgotten during times when I could and remembered while showering or driving or walking the dog with phone left home…you know true ADHD style! My new filter appliance has arrived so I have to try to figure out best practices for now and figure out whether I will need additional supplies above what is supplied and typically used.
BTW, he was an excellent plumber, his work was so refined that the rough plumbing that he did could have easily been on display out in the open rather than hidden away. The problem was that he had started his career with a focus in commercial work with emphasis of restaurant and food industry. It’s a fact that commercial ice machines go better with hot if clear ice is desired. My refrigerator plumbing situation happened near the start of his transition to high-end residential but many of his initial  clients for obvious reasons were chefs who had commercial equipment and finishes in much of their kitchens.my ex was a chef with one of  his old bosses being one of the aforementioned chef clients which is how we wound up there. He was a five star level contractor and made one error. We are all human. Not many contractors can sell their business. His reputation and business model were good enough to do so. I am sure that it was partially a brain fart, partially an experiment. It worked for a little but eventually didn’t.

– We do have low volume/pressure but it is adequate enough to run a complicated drip irrigation system in the garden which has the lowest flow of the house.
– I have zero desire to use the water or ice in the  refrigerator/freezer – so little that when I get around to selecting which model I want for my future renovation I will be asking you for recommendations for units without either.
– The filter appliance that I have purchased is the Coway Aquamega. To be able to use it, I have to connect it to a water line. The manufacturer give two options the first being drilling a hole through the counter and tapping into the sink supply. There are a surprising number of companies with systems that use this concept but that is not gonna happen here ever. Option 2 is to tap into the water line for a refrigerator or other appliance. They supply a T-shaped connector so that people can literally pop it into a cut made in the refrigerator water line tubing allowing for one line to feed both appliances. The great thing is that after my remodel, I can run a water line to a bedroom and have an endless water source without actually having a sink and under sink filter. For now, since I do not want to use the refrigerator water and ice and have not for a decade or so, I am wondering if it would be problematic to use a straight connection rather than the T and just leave the refrigerator disconnected. Will that risk a leak or other problems?
– You have mentioned refrigerator water and ice components developing mold if not in use for a little while. Since mine has not been used for an eternity, I am sure that there is mold involved. I am wondering if that mold might go as far as contaminating the water line in any way. If so, I will have a new one run.
– Finally, so that I know what my future maintenance needs will be, do you know if the concept of a water dispenser getting moldy if not used for awhile would apply to a countertop unit?

I think that that is all of the questions for this topic but once I get this out of the way, I have more for you! 😅
