Rusty water heater woes - repair or replace?

A puddle around the base is a reason to have the leak traced, not proof that the inner tank has failed. Water can come from a fitting, a valve or condensation as well. Rust and unusual noises deserve attention, but the repair-versus-replace decision needs a diagnosis rather than a guess from those signs alone.

Popping or rumbling can be associated with sediment, but that still needs checking rather than an assumption that the tank has failed. If there's an active leak, stop using the heater and arrange safe assessment. Maintenance may help a serviceable unit; it isn't a patch for a leaking tank.

Had a similar issue last winter - tried the quick fix route, thinking it'd buy me some time. Nope... ended up with a flooded basement and an emergency replacement. Sometimes biting the bullet early saves headaches later.

Yeah, quick fixes rarely pan out with rusty tanks. How old's your heater? If it's pushing 10+ years, replacement usually makes more sense... avoids bigger messes later.

Fair point, but age alone isn't always the deciding factor. I've seen heaters pushing 12-13 years still going strong after a proper flush and anode rod replacement. Worth checking those first before dropping cash on a new unit... might buy you a few more years.
