Review: Took 2 WEEKS and cancelling/re ordering to arrive! - Great value and worked as is should, it's nice to have heat in the garage again! The only negative thing to say is that what was supposed to be a 4 day shipment, took over a week! At which point I was forced to cancel and re place the order, which added an additional 3 days of shipping. I think next time I'll just spend the extra $15 and purchase locally to avoid having to deal with a freezing garage for 2 weeks!!
Review: Perfect fit for my Reliance 909 water heater - My local supplier told me I'd have to find a Reliance dealer to get a new thermocouple because they weren't standard. This sounded pretty fishy so I ordered two of these replacements. Perfect fit and now my water heater is up and running again. It was relatively easy to install considering the nature of the job.
