Hi, first time poster here! I've been having some issues with the water supply in my home. It started with my refrigerator losing water pressure when using the water dispenser right after I replaced the water filter. Then gradually making 'water hammer' noises when using the water dispenser or when the ice machine is filling up. Then the water pressure regulator valve started getting loud and makes a high pitched squeal when the water is used anywhere in the house. Adjusting the valve relieves the squealing noise sometimes, but I have to keep adjusting it. I've also noticed that the water heater is making a lot of loud bubbling noises, but not sure if this is related or if that is how water heaters usually sound. I think I've even heard the water heater make some noticeably loud bang noises from time to time. I'm not sure where to start on these problems. Any advice or help would be greatly appreciated. Thanks! P.S. Just found out that if we push hard on the water filter for the fridge, the water will flow again out of the water dispenser. So weird.
