JOINING DISSIMILAR PIPE ILLUSTRATED

there is a fitting called a DESANKO fitting but you mention that at a home depot people are gonna look at you funny. all it is - is a beefed up plastic hub that fits into a cast iron hub and can be oakumed and leaded in place without melting. instead of using hot lead use the newer two part epoxies.

drawings etc. are submitted by mostly the moderators of that specific section. lazypup used to be the moderator of the plumbing section as I am of the electrical section. If it helps to straighten out a situation then we will add a drawing or two.
Reason for the bowl level not to be consistent is how soon the flapper snaps shut when the tank is flushed. sometimes it closes later or sooner and the time the tank fills as well as the bowl fill tube is later or shorter.

Brass is acceptable to join copper to galvanized. A nipple of at least 6" in length should be used.

Brass is much closer to Galv. on the galvanic scale than copper is and makes a good transition material.

The all rubber Fernco is not allowed above ground an inside under many codes a banded coupling such as a Fernco Proflex should be used.

haven't seen this stuff since I was a little youngun
thought it was chromed copper-soldered together at joints "copper" no less
but the main tubing is thin walled steel? I know magnet sticks to it
could not get it to solder-any clues on the age or what I'm into here?
