    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.

    Looks to be a trap primer, it`s to keep a trap seal in a floor drain. It should only release water to the trap when another faucet is turned on. May be faulty.

    That is definitely a trap primer. If your able to find the same one. You can undue the nut and just change the guts and nut. Pay close attention to the flow. There will be an arrow on it

    Most people don't have a trap primer in their homes.

    Thank you guys, you are absolutely correct. A quick search of the internet for trap primer and I found exactly the same part, with a local plumbing supply shop that has them in stock.

    The next question is however so I need to actually replace it? One of the guys on staff at the supply shop suggested that since my furnace and humidifier both already drain into that floor pipe that they will keep the trap plenty supplied with water so the primer is overkill.

    Any thoughts?

    As long as things drain into it ALL YEAR ROUND, you do not need it. A humidifier and "furnace" would normally only drain during the winter months.
