Hole on top of hot water tank

[mnicholet]

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.

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 would report the use of PVC on the TPR valve.

[Ian Gills]

Probably to be told that it's CPVC.
