Outside pvc pipe leaking

Outside of my basement I have two pvc pipes side by side. One is pressure relief for the hot water heater. The other is tied to the houses cold water supply. There is a fitting between the house water supply and the leaking pipe. This is not connected to the A/C drain system. I have a picture that might help. The hot water heater is 12 years old if that makes a difference. Thanks in advance for any help you can provide.

Welcome to the forums.

That looks like a PRV (pressure reducing valve). It should say it on it.
That reduces the incoming water pressure to a lower usable level.

If that is definitely the leaking pipe then it may need to be replaced.

Since this is like a one way valve..... it requires a pressure tank to be on the water heater. Otherwise when the water heater heats the water and it expands.... it can be forced out of unexpected places.

If it's the drain from the heater then you'll need a new t&p valve or a new heater because something is wrong
