mine came with a small ball looking float, but if you have a sealed tank I don't know. you might want to contact the people you got it from. I only use mine for plant water, so I usually just fill a bucket then turn the system off. I also noticed a lot of waste for the amount of good water I get. I have a 5 filter system also.

i'd rather not be told by the all powerful state how far i may rise and how much i can accumulate. i'd rather have the freedom to fail than the mediocrity of an enforced comfortable poverty. a free market allows such a life. all else is slavery.DelusionsofNormalty
