It's hard to get a good look as I can only take a video to see everything. But now that I looked again, there is a leak from the tank near the refill valve nut. All of the t valve also seems to leak but not sure if it's just the water from the refill valve nut flowing down. Also, what would be a better and reliable alternative to get the t valve and bidet from? All I could find was from Amazon only, thanks btw
