Although Shane Tucker, the Limric plumber, specifically asked for a 50-gal hot water heater no taller than 42 inches (due to space limitations), the unit delivered to him was over 60 inches. Shane asked me whether I could live with sent unit or wait for shorter unit. I told him that I could live with the taller unit if he could make it fit. Shane had to re-pipe to make the unit fit, but the end result was exceptional. Although the installed unit id great, Limric parts people need to deliver what is requested.
