Not quite a rant yet, but I tried having a bath for the first time in my house, 2 years since moving in a couple weeks ago. It's a big corner tub, but not hot-tub massive or anything.
Started running out of hot water at about 1/2-2/3 full. I may have ran the dishwasher or done laundry that day so thought maybe it was a bit low. A week later I tried again and it was a the same result.
So today I tried flushing it. I'm assuming the previous owners probably never did it once. Water ran clear almost immediately so I don't think it's that the tank had a massive layer of sediment.
I'm not sure if it's that the tank is just too small or if my hot water tank is nearing the end of it's life. It's probably the original from the build so it's nearing 20 years old.
I might try putting in a new dip tube to see if that's the issue, and will probably throw a new sacrificial anode while I'm at it, but I'm wondering if the old gal just isn't long for this world. Really don't want to replace it, but it might be worth it in the end.
