I feel I must give a review of my new one, since it is so different from the original.
I had a Ritchie automatic heated waterer that lasted over 30 years with little repairs. I was very happy with it, recommenced the brand and style to others, and put in a new one in a new location 4 years ago. I have repaired and replaced so much of it. And in talking to others locally, apparently Ritchie waterers just aren't what they used to be.
I had trouble with the heat tape right away, but managed to fix it with the existing heat tape. Earlier this fall we had to replace the two heaters under the water pan. And yesterday we had to replace the heat tape. All on a 4 year old waterer. That is more repairs than i ever did on the old one in 30 years.
So...Not a brand I would recommend.
