I like to look at my body like a machine - if there's a constant flow of corrosive acid and the gears aren't turning nearly as often as they should, I, as a machine am not a very good one. 

What usually happens is that the problem points that are most susceptible to corrosion go bad, you replace them, and the system works just fine for decades on decades more.What you need to make sure of, though, is that the sewer line to the street is uncompromised.

I've listened to enough escapist fantasies to learn to hate all the empty, vapid, corrosive, soul-sucking dreams of something for nothing attached to those dirty little tickets.This thread has served to remind me yet again of how few people come from a broke childhood to real estate investing as a way to build lasting wealth and find financial independence for their families, of how incredibly fortunate I am, and how grateful I should be to those who have helped me along the way.

I also use dielectric grease on the battery connections to prevent corrosion.

Microbial influenced corrosion (in addition to others) often manifests with creating blisters on the outside of a pipe as the interior of the pipe develops a depression.

We inherited several older 100/150amp panels in a 6 unit that had to be upgraded, (buss bar corrosion etc).

I showed him the dust & corrosion on the window Al capping & he was still not convinced.

He could tell by popping off the doors they the insulation was falling off (sparks flied at one point) and the evaporator condenser was heavily corrosive which can leak harmful R22 refrigerant into the home plus found bio growth inside leading to potential health concerns.
