Caslon, Cimarron

Caslon on a Kohler Cimarron

A month ago, we noticed that our pump was coming on when we weren’t using any water. We immediately suspected the toilet because there was no evidence of water anywhere (on the floor, leaking under the house, etc.), but when we shut off the water supply to the toilet before going to bed, the tank was still full of water in the morning. The gaskets in our kitchen faucet were starting to fail, and it was occasionally leaking down the stem of the faucet, so we replaced the cartridge hoping this would solve our water problem. The faucet works a lot better, but we were still losing water.

We tried turning off the pump at night to confirm we really were losing water, and when we got up in the morning, we had no pressure. The combination of turning off the pump and the toilet supply resulted in no loss in pressure, so the leak was somewhere in the toilet after all. It wasn’t the flapper valve (or the tank would be empty in the morning), and we didn’t see any drips or leaks, so the supply must have been leaking into the top tank somewhere under the water and draining into the bowl where we didn’t notice it.

The obvious fix for this is to replace the stuff in the tank. But the toilet didn’t really work very well anyway, and used the full 1.6 gallons per flush. Andrea installed a dual flush kit that was supposed to use less water for liquid waste, but it didn’t work: the lower “number one” button didn’t release enough water into the bowl for it to actually flush. 1.6 gallons of water doesn’t sound like much, but we’re currently paying 10 cents a gallon for water, so we’re spending more than a dollar a day just to flush the toilet. We have an outhouse, but because we’re so close to Goldstream Creek, it can’t be in the ground and needs to be pumped out whenever it gets full. So our best option was to replace the leaking toilet with something that won’t leak, and uses less than the standard 1.6 gallons of water per flush.

The two current strategies to lowering water consumption in a toilet are to make the top tank smaller so less water is used for every flush, or to implement a dual flush setup where a small amount of water is used for liquids and the full volume flushes solids. Consumer Reports doesn’t give the dual flush models very high ratings, mostly because the bowl isn’t rinsed as well when so little water is used. As a result, we decided to get a toilet that uses a smaller top tank (1.28 gallons per flush). The highest rated model by Consumer Reports is an American Standard one-piece “Cadet 3,” but the local plumbing place and the box stores didn’t have that model in stock. Getting one shipped to Alaska would have taken more than two months. The next place models were the two-piece version of the Cadet 3 and the Kohler Cimarron. Consumer Reports gave the Cimarron slightly higher marks overall, with better bowl cleaning but worse solid waste elimination ratings. While we were in the store, we went to the web site for the company that rates toilets for solid waste elimination (www.map-testing.com) and consulted the latest ratings (from April 4th (!)). The Cimarron was better rated for this statistic (1,000 vs. 800), so that’s what we got.

Installation went smoothly. Thus far, we’re satisfied. What is surprising about the toilet is how fast it flushes. It empties the top tank into the bowl in less than a second, and the bowl empties almost immediately after that. It seems that the strategy is to dump almost all of the top tank water into the bowl as quickly as possible to eliminate waste, and use the small amount remaining to wash down the bowl. So far so good! We’re saving more than three cents each time we flush, and hopefully we will have many fewer double (and more…) flush events.
