Rusted pipe connections only

[Jgaro]

Hi all,

In the picture attached, you can see that I have a handful of rusty connections only in the joints of the pipe coming off of my hot water heater. Any thoughts on whether this should be addressed proactively and why?

Thanks!

where is the valve for the water heater?

More pictures attached. Not sure which valve you are referring to. The one going into the heater looks fine. All connections on the exit side and beyond are rusted on joints only.

It looks like the valve is on the galv. nipple in the picture and the flex does a 180 loop.

If you wanted it to look nice sure go ahead and replace it but other than that no need.

Galvanized should not be used for gas . Black iron should not be used for water .

The pipe is typically coated. The fittings are just oiled. This is normal. If you are worried how it looks you can brush it off and give it a coat of paint.

I would be more concerned with the draft hood connection...

Water heater draft hoods serve a very important purpose and if not installed correctly, carbon monoxide gases may be expelled into the living space. I’m pretty sure you’re aware how dangerous Carbon Monoxide can be…

Just might wake up dead...

Except steam and condensate are run in black pipe . As are chill water and condenser water .

That is the way they do it here .
