29 years out of a hot water tank

Wife goes into the basement Wednesday to get some meat out of the freezer, "I think the hot water tank is leaking". Sure enough, a puddle around the bottom of the tank. Must be starting to rot out from the inside. The tank was here when we bought the house in 2019 and is no spring chicken, an Estate brand with a date code of 1996. She's well past her prime. It still made decent enough hot water, but I will say the water kinda stank. The colors and chunks that drained from this bad boy were impressive! Literally last week I was telling a friend of mine how old my tank was and "I'm gonna run it until it croaks".

There was a lot of corroded copper (sweated pipe to the tank + unions and general corrosion from no dielectric nipples) and the two shutoff valves didn't function anymore, also pair that with some old piercing valves for whole home humidifiers, it was time to cut a lot of this mess out.

Some hate then, but I think Sharkbite are some of the easiest and very reliable (IF prepped/installed right) ways to transition from copper to PEX. So I cut the old corroded and pierced stubs back to clean copper and installed two 3/4 Sharkbite Max ball valves. From there, 3-4" stubs of PEX-B with PEX-B to 3/4 male pipe thread 90* elbows. Then the tank is connected with corrugated 3/4 FIP to 3/4 FIP hoses. I wanted this to be (A) serviceable in the future, (B) little to NO strain on any piping and (C) clean and routed well. Since the old sweated lines to the tank were effectively supporting this long copper span, I took some copper strapping and secured both hot/cold runs to a floor joist near the tank so they do not have any undue strain.

The old tank was a 40 gal and I upgraded to a 50gal Rheem Performance Platinum from Home Depot. 12 year warranty, 40k BTU... nice unit. My bright self totally did not realize how much wider this new one was until I got it home -- I also had to re-work my gas feed. A couple of black iron 1/2" 90s and 1/2" nipples and we were all set. BTW, 3 different stores were out of black iron 1/2" 90s... how lol. Replaced the vent ducting, excellent drafting when running.

After lighting, we had hot water in about 40 minutes. That was fast! I put it on 'B' and it is supposed to be 130* water. Seems way hotter than the old tank. I am super pleased with the quick hot water and in general how this replacement turned out, especially for never changing out a HWT before. I have been the flashlight holder for Dad many of times, but this was my first go around.
 
Sweet and nice looking job!!

We have the same hot water heater installed 2016 (ruh roh 9 years lol). I too wish I had the chops to have DIY'd. the guy who did it was a HD contractor and he did it all by himself. He even did the ground wire from hot to cold (I am curious if there is any way to test it, because I put in a shark bite but copied his work where a heavy gauge wire connects both sides of the shark bite.

Flash forward to 2020, got a high efficiency furnace, and so that co. installed a stainless steel chimney liner for the hot water heater, since it was orphaned....

Also believe it or not an inspector eventually came to look at the hot water heater, but never for the furnace. Also, I don't get the feeling the inspector even knew what he was looking at.

You've never done one before? Congrats, it looks great! (I have not done one, only helped a buddy)
 
Don't you have to have an expansion tank?

Also, since the water stank, I'm betting if the Anode rod had been changed, the old heater would have lasted even longer.
No expansion tank, we are on older municipal water (old farm town), no pressure reducing valve or back flow preventers, old water meter. When/if the time comes for service update from the water authority, then I'll probably add one. But as it stands any excess water pressure harmlessly goes back into the main.

I know I never touched this old tank's anode. I am going to ensure this new tank is annually flushed and the anode serviced.
 
Correct me if I'm wrong, but isn't a longer lifespan of a water heater usually indicative of a lower mineral content in the water?
Where I'm from, you're lucky to get 10 years out of one.
 
Nice job.

If you nice stinky water with the new heater, it is likely due to a reaction with the anode rod. In that case the best fix is a powered anode rod.

Good to know. Thanks. It is early on but so far no smell at all.

I think to a point yes, the anode will just give all its got and the tank will slowly rot away. But I’ve always thought we had decent municipal water here.
 
Kudos for including the spider webs. We also have a utility basement that looks similar. I go through it several times a year to clear out the spider webs. They must be eating some type of critters down there, so are probably beneficial.
 
Looks great! I'm a shark bite plumber at best and haven't had one fail me yet. My Lowes purchsed "Whirlpool" brand 40gal tall is pushing 20yrs old. I believe it's a US Craftmaster. I replaced the leaking plastic drain valve with a brass one 10+ years ago and had to replace the thermocouple once about 5yrs ago. We tend to get a decent lifespan out of water heaters in western NY. Great Lakes water quality? I dunno.

I have assembled a sharkbite flex line / shut off kit, new gas line w/ shut off, brass replacement drain valve, etc and have it all in a box near the water heater so I hopefully have all the accessories needed when she starts to leak. Hopefully at that point, all I'll have to do is load a new WH in the back of the Traverse and have at it. I have no idea what the going rate is for a commercial outfit to R/R one for you. I'd guess at $2-3K these days?

Installed the same Rheem 4 years ago. With kids, we keep between B and C, as somehow everyone takes a shower around the same time. Very quick unit!

I would have to figure that would be an accurate price. Plumbing sure isn’t cheap. The new tank was $869 at Home Depot, about $125 for fittings, hoses, etc. and a $15 lunch at Piccassos… had to treat my old man for picking me up and running me to Depot to get the tank in the back of his Silverado. Prob could’ve fit in the Tahoe and Burb but I think Dad enjoys helping. I’ll never say no to that.

It's crazy. I put the same Whirlpool brand water heater in my last home in West Falls around 2006. My brother helped me. IIRC, it was just over $200 at Lowes at the time.
