Now that you know you have a PRV we KNOW you have a closed plumbing system and the 100psi spikes are the result of thermal expansion. You can refer to the link 14 posts above for a detailed explanation of thermal expansion. The PRV creates a closed plumbing system. Since your internal pressure is 60 psi we can assume that portion of the PRV is working. We can prove that if we know the street side pressure. The N35B does have a built-in bypass feature that limits the internal pressure to 10psi above the supply pressure. I don't trust the built-in bypass because the intent of a closed plumbing system is to prevent back-flow into the main system from homes. Click here for N35B details and read the TROUBLESHOOTING section CAREFULLY. You may be experiencing the dribble now just because the new fridge has a valve that is sensitive to excess pressure. The bypass on the PRV might have just failed and is now causing you a thermal expansion problem. That is why the preferred thermal expansion control device is a thermal expansion tank. Here's what I would do... 1. Measure supply (street side of the PRV) pressure for reference and to know how much the PRV is reducing the pressure for future troubleshooting. 2. If the PRV is not reducing pressure then replace it. 3. Install a thermal expansion tank at the cold inlet for the WH and sized from the link 14 posts above including a 1/4 turn ball valve so the tank is easily serviced in the future. 4. When that is done, if the fridge leak persists then back to GE, BUT, without a receipt from a plumber you may be banging your head against a wall with them unless you get a GE tech that has field experience and is knowledgeable.

I don't recall the poster asking for advice about whether to get the instant hot. Her query was about the best way to get the cold water. But since you brought it up.... For me, getting the instant hot was a big plus for daily life. I make French press coffee a few days a week. I run the Bodum pot under the hot water for a few seconds to get it nice and hot and then make the coffee. Thirty seconds of prep time. When I want to use broth concentrate to make a cup or two of broth and don't want to open a fresh box, the instant hot lets me make the broth in a flash. It is great for adding really hot water to a simmering pot that needs liquid replenished. And it works great in a really hard to clean pan. I had never understood what the big deal was about the instant hot. But now that I have it, I think it provides a great deal of convenience. Sure, it uses energy, but so does a dishwasher. But few people suggest that a dishwasher is a frivolous use of energy. I still don't get why chilled water is such a big deal. It seems to come out of the tap pretty cold already and there are always ice cubes. But there are people who drink water all day long and want it really cold right then and there. So I guess it is all about what is important to you. Yes, it uses energy

Refrigerators that dispense chilled water have a reservoir or tubing loop in the refrigerator section, typically behind the crisper drawers. Perhaps Samsung isn't designed with such?

I think eam44 means to filter the water for your ice makes also, giving you filtered ice in filtered water. I think it's a great idea... prob because that's what we did : ) Frankly, we have a basic 3-filter water system under our sink, with water dispenser above. I fill a glass pitcher and keep it in the fridge, changing the pitcher every couple days to wash. Be aware there are several kinds of water filter systems if you should go that route. Reverse Osmosis is one (RO). We opted out of that as we found the water to be too flat for coffee and tea, but that's our preference only and I understand other's do like it. To best answer your own question, I'd ask how important is immediate hot and cold filtered water, countertop accessible, to you and yours? If it's high on the list, then you may not want a simpler solution of 'just filtered' and refrigerated, as we chose.
