Agree with a few of the previous posters, you are on borrowed time with the age of the water heater. Get multiple quotes for replacement and make sure they are all similar in regards to size of the tank, including expansion tank, etc....

I doubt they was as lucky as you, they probably had theirs replaced. You have several contractors/plumbers you can call and get estimates. Or big box stores? Or TECO has program I think 🤔 some said added cost to there bill in increments?

:ho: Link to TECO Rebate Program......

Thanks so much. We’re in the market for a new tank, including an expansion tank.

Expansion Tank on top of a Water Heater??? I never heard of that??

Why? Is it to cushion the variable water pressure in the Water Heater???

To absorb the pressure caused by heating the water. Also to comply with the local plumbing code.

FYI, our new hot water heater with expansion tank and drip pan were installed on Thursday. After checking with four recommendations, we had Roger Pearce do the work and we are well pleased with the work and price. I always like dealing directly with the owner of the business who also does the work.
Thank you for all the helpful posts.
