A. In the past, Ifo toilets were popular in the U.S. because there were many people who were seeking a low water consuming toilet, and virtually no domestic brands fulfill that need. In the 1990's it became a Federal law that all toilets in the U.S. must be able to flush with 1.6 gallons or less. At that time all American toilet manufacturers started to produce 1.6 gpf toilets (with varying results). After a bit of trial and error, the bugs were worked out and within a few years of that low-flow ruling, most toilets available in the U.S. flushed well. This created great competition for the uniquely designed Ifo toilets. As the market in the US decreased for the unique Ifo toilets, so did the distribution avenue for parts, until Ifo finally decided to stop distributing in the US entirely. While we still have limited stock of some parts, it is becoming increasingly difficult for us to be able to offer genuine Ifo toilet parts at low prices due to the limited availability. We are exploring options for "will-fit" parts, and will offer them as we find parts that meet our high standards and expectations. In the meantime, if you plan to keep your Swedish Ifo toilet for the foreseeable future, we recommend stocking up as supply of genuine Swedish Ifo parts will eventually dry up in the US.
