I originally built my home myself in 2006. In 2012 I found the original Moen unit I installed was beginning to leak around the swivel area of the neck. In mid 2012 I replaced that unit with the ADLER series which is a mid range in inexpensive unit in the $112. dollar range..
Believe it or not like the 1st unit the 2nd replacement unit is failing just after 6-8 months on the job?
The neck of the Adler series (replacement 2nd series) is actually leaking through the metal itself. The problem lies squarely in the metal being porous along the entire neck of the ADLER. It is actually bleeding right through the metal and the chrome. It runs about 6-8 inches along the underneath of the neck itself.
That's it folks, Forewarned is forearmed!
