I was recently looking at my pipes and they look corroded. I think I can access all my plumbing from the basement without tearing down walls except the maybe the radiators. I dont think it's the original plumbing. I was wondering how much a plumber gets for this and if it's something that's easy to do yourself. Do you think my pipes should be replaced soon. The water heater is from 2015 and the boiler is 1972 which I'm replace this next summer. I plan to install a water softener since the water is like 27000 grains
