Relief valve. It should be piped down to the floor or to a funnel floor drain I reckon. It goes off if there is too much pressure in the tank. I have also never seen push-connect fittings on a hot water tank.
Thanks. I’ve contacted a plumber about installing a funnel floor drain. And a mixer valve.
I suppose those fittings should be welded and not push connect but I guess whatever they had at the time.
Is it a good idea to replace them?
If they work fine I wouldn't touch somethin that aint broke. Also you do not need a funnel floor drain. As long as there is a floor drain in the room then the water will drain there if there is a leak or the PRV goes off. I have seen the PRV piped down to the floor beside the tank.
Temperature & Pressure relief valve. It should be piped to within 6” of the floor but not closer than 2” in an appropriate material, not pvc, in at least 3/4” piping. If the water heater is sitting on material that can be damaged in the event of a leak, then there should be a water heater pan under the water heater that is piped to a drain with an air gap. The water heater supply lines should have been soldered in since there’s already unions there. It does look like you have some oxidation above the push-connect fittings. This is based on code at my location and does not include all the code requirements.
It is indeed a relief valve
I'd reckon it's a relief valve.

Does look that way. I’ll ask when the plumber drops by. Thanks
So if you zoom in on your picture it reads “relief valve” on top
Aha! Thanks
