Hole on top of hot water tank

This hot water tank has a hole on top (missing cap?) and has foam insulation in it. I dont think it is a problem but I wanted to get some other advice. Any issues with this? Thank you.

Thats so you can see how full it is…:lol:
(sorry I couldn’t help it)

Anode rod location?

My guess is the tank jacket is universal for other models and the hole is either for a top mount TPR valve or an electrical connection port for electric models.

I believe Mr. Newland Is the winner !!!..Congratulations Bob…Dale …tell him what He’s won…

I would report the use of PVC on the TPR valve.

Probably to be told that it’s CPVC.

I’m waiting Dale? Well??? :stuck_out_tongue:
