Reclaimed water and your drinking water
The City of Largo supplies reclaimed water, which is recycled wastewater used to water lawns and in some businesses. It is not meant for drinking, and its pipes must be kept separate from the drinking water supply.
That separation is the reason backflow devices and cross-connection checks exist. In November 2019, Largo told reclaimed water customers to stop using it after tests showed it was not meeting disinfection standards, and the city said drinking water and indoor tap water were not affected. A plumber can check that irrigation plumbing has the right backflow protection. See backflow testing and prevention.
A large residential city
Largo has roughly 82,000 residents and almost 48,000 housing units, and it grew as a bedroom community after farming declined in the 1960s. That means many kinds of homes, from older neighborhoods to newer subdivisions.
In a city this size, the plumbing problem often tracks the age of the house. Older homes bring corroded galvanized pipe and cast iron drains, while newer ones bring plastic lines and failing fixtures. A good first step is to say how old the house is when you call. See repiping for older pipe and leak detection for hidden leaks.

Geography
ZIP codes in the Largo area
ZIP codes that cover parts of the area include 33770, 33771, 33773, 33774, 33778 and 33779. This is for orientation only and is not a coverage promise. Largo spans many ZIP codes, so read your address to the dispatcher and ignore the ZIP when in doubt.
Drains, sewers and everyday repairs
Slow drains, running toilets and weak water pressure are the common calls anywhere. A drain that clogs again and again usually has a cause in the pipe, so ask for a camera look before paying for another cleaning.
See drain cleaning, toilet repair and water line repair for what each involves. A sewer problem after heavy rain may point to a cracked lateral, covered under sewer line repair.
Water heaters
Many Largo homes have tank water heaters in garages or closets. A tank that is ten years old or more is worth watching, and a leak at the base means replacement. See water heater replacement and tankless service for the options.
Condos, rentals and who to call first
Largo has plenty of condos, townhomes and rentals. In a condo, a leak can reach the unit below, and the association may control the main shutoff and the repair rules. Tell the association or property manager at once, and mention it to the dispatcher.
Renters should report a leak to the landlord in writing and keep photos. If water is still running, shut off the valve under the fixture or the main valve and call the line. Ask who approves the repair, since that can decide how fast the work starts.
Common questions
Largo plumbing questions
Yes. The City of Largo says its reclaimed water is recycled wastewater for watering lawns and some business uses. It is not for drinking.
Reclaimed pipes must never connect to the drinking water supply. Backflow devices and cross-connection checks protect against that.
Look at the year the house was built. Older homes may have galvanized or early copper pipe, and newer ones usually have plastic. A plumber can tell what is in the walls.
Largo is a big city, so give the dispatcher your street address and ask whether a contractor covers that part of town.
