toilets work off of siphon.more correctly it's the timely transfer of water from the tank to the bowl through the ports that starts the siphon and carrys the solids and water downstream,thus completing a flush.i also live in florida and due to lots of hard water everywhere can tell you that most likely the toilets are full of deposits and need to be replaced or are of poor quality.all of the toilets from home depot are trash i would suggest getting one from the factory or from a plumbing supply house.DO NOT GET A 1.28gpf...1.6gpf is still legal
They advertising 24/7 service, when I called on Sunday February 11 2018, I was told Sunday service was not available. I even called twice to be sure I heard the correct information. Again I was informed no service on Sunday. I mentioned their advertising said 24/7 service. I was told no service on Sunday. I asked what 24/7 meant and did not get an answer. I am Advantage Plan member but this made not difference. This is a complete waste of money. Don't buy the Advantage Plan. This company is a complete fraud.
