Keeping a Key Biscayne septic system healthy
A septic tank in Key Biscayne only needs a few things from you. Pump it on a schedule, keep heavy vehicles off the drain field, and send only water and waste down the drains. Grease, wipes and harsh chemicals shorten the life of the tank and the field. A quick yearly look at the lids and the ground above the field catches small problems early.
Early septic warnings Key Biscayne homeowners notice
The first signs in Key Biscayne are usually subtle. A toilet that takes an extra second to clear, a faint smell near the tank after rain, or a patch of grass that stays greener than the rest. Each one on its own may be nothing. Two or three together mean it is time to have the tank and drain field checked.
Getting a fair quote in Key Biscayne
A fair septic quote in Key Biscayne spells out the tank size, what is included in the visit and what would cost extra. Pumping prices vary with tank size and access. Repairs should come with a written description of the problem. If a company recommends a full replacement, ask what a repair would look like instead.
Septic permits and rules around Key Biscayne
Septic permits near Key Biscayne are handled at the county or state level rather than by the city. Repairs, replacements and new installations usually need a permit and an inspection. Your septic company can pull the permit for you. If you are buying or selling a home, ask whether a septic inspection is required at closing.
