Over the years I have purchased well over 20 Rubbermaid Stock Tanks both 150 gal and 200 gal tanks. I have had leaks in at least half these tanks, some I was able to repair and some were not because of the size of the leak. I called Rubbermaid to request information as to the best way to repair the cracks and leaks. They were very unhelpful and disinterested in providing any information. They were only concerned with selling me a new one. The warranty is not much help because it is only a limited one-year warranty. This product is as good as others on the market and works well until it cracks and it will crack if used regularly. We keep over 40 head of horses and they are not abusive to the tanks. I'm not sure, because of the lack of information from Rubbermaid, but it appears that the temperature changes from winter to summer over one or two years time causes the tanks to loose their strength and crack from stress. In all fairness, I will say that we do have some tanks that are over five years old and have not cracked.We also have a stack of them that need to be removed but the land fills won't take them.
I own 5 Rubbermaid stock tanks ranging from 100 gal. up to the largest a 250 gal. Rubbermaid's product is great. The structure is strong built, holds up to my bull abusing it and it holds up to winter weather conditions.
This tank is the perfect size for horses. It does not rust and the Rubbermaid water float that is purchased separately fits perfectly. It also is big enough that it is not easily pushed around and does not dent if it gets kicked. In addition, it holds enough water that the stock tank heater works well. Also, its material is easily drilled into to attach any guides, etc to the top. The drain on the bottom works well.
