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
My plan was to have an old kitchen faucet head replaced with a new one I had bought, a 5 minute job at most. The plumber told me it would first be a $28 assessment fee and then a "job " cost but they could not quote phone costs or give me any indication of a range cost. I declined to use them and to find a handyman instead. Plumbers stories significantly overcharging seem prevalent and I could see it could well happen to me. I got a handyman who did the job in 3 minutes flat! The Plumbing Costs Chart you sent out is good, it shows it would probably have cost me $200 for 5 minutes plus $28 assessment fee.
Fixing appliances is not easy. It is tough as well as risky. You stand the risk of getting an electric shock. You should never handle them yourself. It is the job of a good workman. Hiring a workman is also necessary for reliable work. An expert provides work that lasts long. This is true for all types of devices. If you are not hiring a workman with experience, the issue will come back. You need to take care while choosing the workman. A poor workman will cost you money and the issue will still be there. You need to avoid this at all costs.
Seriously, I've done a lot of plumbing repairs, from installing sinks and fixtures, toilet replacement and repair, caulking and recaulking to replacing a garbage disposal. Probably the most frustrating thing I've encountered was needing a specialty tool for one repair; for me it was a basin wrench. Some hardware stores will loan tools, so it's worth it to find that out ahead of time.
Sometimes you might need your sewer and drain lines inspected. For instance, if your sewage is backed up, then you probably want to determine what the cause is. In instances where we can't physically get to the problem to see what it is, we can use a sewer video camera to go down into your lines and take a video showing us what's the issue then. That way we'll know the appropriate way to deal with it.
