Claim 10:
11. A condensate trap comprising:
a back portion comprising a first passage enclosed between a first wall and a second wall, the back portion further comprising:
a first opening connecting the first wall and the second wall;
a first float placed over the first opening such that the first float does not travel below the first opening; and
