After a company came into my house to replace my hot water tank after a flood damaged my previous one the technician turned the water back on and commented that someone seems to be using the water. We could hear water running through the pipes. After checking that no one was using the water the technician just left. The sound was definitely not happening before the water tank was installed but I assumed that it was just from the new water tank being filled. 5 hours later I woke up to get ready for work and I heard the same sound and went to the basement to check. Sure enough water was still running through my pipes somewhere. I grabbed a step stool and started following the pipes from the water main and discovered this... junction or valve? It clearly looks like there has been some corrosion on it, and even holes on the nut. It seems that it should be replaced but I have to identify it before I can buy a replacement. Water comes in on the one side, and exits out in-line on the other side going to my bathroom in the back of the house. The outlet on the bottom is attached to a pipe that leads into a plastic pipe in my basement floor that I believe is just a drain of some kind (the furnace uses this pipe to drain condensation into, and the humidifier for the furnace also has a tube draining into it).
Anyone know what this junction is called? Is it a valve of some kind? My water is currently shut off at the main so I'm not wasting water. There is also a hissing sound coming from the holes in the nut that you see. If I block the holes with my fingers the hissing stops (but the water doesn't stop flowing) and my fingers will be slightly wet after.
