Hi. I have a strange problem with the hot water in my bathroom sink. The hot water in the shower and the kitchen are perfectly fine. The problem exists only in the bathroom sink. When I turn on the hot water, the water pressure goes from full pressure to a drip in a matter of seconds. It's not always the same result. Sometimes it maintains a weak drizzle for about a minute before it goes down to a drip. But it always starts out strong and gradually weakens. Here's a video so you get a better idea: https://imgur.com/a/bGCggbo Does anyone have any clue what could be the problem and how I might be able to fix it? Thanks!
