Well so far its been a day with my new rheem tank. Install was about an hour as I had already drained the tank and also the guy didnt replace the venting pipe with a new one because he said if I was too have a inspection today it would fail on the furnance piping as its the same stuff. So I will address that at a later date.
I can see the part that people have to replace on rheem tanks and other tanks with intellivents. The gas ignition goes on and off multiple times a day and this is the bit that is required to be serviced. You can order the part from amazon.ca for $20 - I was thinking of ordering it just so I had it on me if I ever do have that issue.
