Summer in Largo means long days, dry spells between storms, and lawn irrigation systems running hard to keep up. For homeowners with a dedicated irrigation well, that setup offers real advantages — independence from city water restrictions, lower utility bills, and consistent pressure for the yard. But a lawn irrigation well in Florida also comes with its own set of responsibilities, and a handful of mistakes can quietly turn a reliable system into an expensive headache.

Here are the most common irrigation well mistakes Largo homeowners make — and what to do instead.

Skipping the Permit Process Before Drilling

Florida takes groundwater regulation seriously, and Pinellas County is no exception. Any new irrigation well requires a Florida irrigation well permit before drilling begins. This involves coordination with the Southwest Florida Water Management District (SWFWMD) and local county requirements.

Some homeowners try to skip this step to save time. That’s a mistake that can result in fines, required abandonment of the well, and complications if you ever sell the property. Permitted wells are also documented in county records, which protects you down the road. Always pull the proper permits — and work with a licensed driller who handles that process as part of the job.

Running the Pump Dry

A well pump dry run is one of the fastest ways to destroy a submersible pump. When a pump runs without water — due to a dropping water table, a clog, or a mechanical failure — it overheats quickly. Submersible pumps depend on the water moving through them to stay cool.

In Largo and across Pinellas County, the Floridan Aquifer system sits beneath a limestone geology that can shift seasonally. During a dry summer, water levels can drop in shallow irrigation wells faster than homeowners expect. Signs of a dry run problem include the pump cycling rapidly, reduced pressure at the heads, or strange sounds from the system. If you notice any of these, shut down the system and have a professional evaluate it before running it again.

Installing a dry-run protection device or a low-water cutoff switch is a straightforward way to protect your investment. Ask about these options when your system is installed or serviced.

Ignoring Changes in Water Quality

Florida groundwater is not static. Over time — and sometimes season to season — the water coming from your irrigation well Largo property sits above can shift in chemistry. Common issues in this region include increased sulfur content, iron-rich water, and sand intrusion from the aquifer.

These changes matter more than homeowners often realize. Sulfur and iron deposits can clog sprinkler heads, corrode fittings, and stain driveways, sidewalks, and home exteriors. Sand intrusion causes accelerated wear inside the pump itself, shortening its service life significantly.

If your concrete driveway or fence posts are developing orange or yellow staining, or if your sprinkler heads are clogging more frequently than they used to, the water quality from your well may have changed. A water test is a simple step that can identify the problem early and prevent bigger damage downstream.

Neglecting Routine Maintenance

Irrigation wells are out of sight, which makes it easy to operate on a “set it and forget it” mindset. That approach leads to problems that compound over time.

What Routine Maintenance Should Include

• Annual inspection of pump performance and pressure output
• Checking for sand or sediment in the system
• Inspecting the well casing and cap for integrity
• Testing water quality for mineral content and pH shifts
• Reviewing the condition of pressure tanks and electrical connections

A well maintenance agreement is one of the most practical ways to keep an irrigation well running efficiently without having to remember to schedule individual service calls. Scheduled check-ins catch small issues before they become full system failures.

Sizing the Pump Wrong for the System

Pump sizing is a technical calculation, not a guess. An undersized pump can’t keep up with irrigation demand, leaving sections of the yard dry. An oversized pump creates excess pressure that stresses sprinkler heads, fittings, and the wellbore itself.

This mistake usually happens when a homeowner adds irrigation zones after the original system was installed — without upgrading the pump — or when a replacement pump is chosen without proper evaluation. The pump needs to be matched to the total gallons per minute required by the irrigation design, the depth of the well, and the static water level.

The team at Accurate Drilling Solutions in Largo evaluates these variables before recommending any pump installation or replacement. Getting this right from the start protects both the well and the irrigation system it supplies.

Not Preparing for Hurricane Season

Largo sits squarely in Tampa Bay’s hurricane corridor. Power outages during storm season are not a question of if — they’re a question of when. Most irrigation well pumps run on standard electrical power, which means they go offline when the grid does.

Homeowners often don’t think about this until after a storm when the lawn goes unwatered for a week and turf damage sets in. More importantly, if your well system has any electronic controls or pump protection devices, a power surge can damage them.

Before summer storm season ramps up, make sure your system has proper surge protection. If extended outages are a concern, discuss backup power options with a qualified well service professional.

Waiting Too Long to Address a Problem

Irrigation systems give early warning signs before they fail completely. Uneven coverage, pressure drops, frequent pump cycling, unusual odors from the water, or sprinkler heads that won’t retract are all signals worth investigating. The mistake most homeowners make is watching those signs for weeks — or months — before calling for help.

Early service visits almost always result in simpler, less disruptive repairs. Waiting until the system stops working means more time without irrigation, potential turf loss, and frequently a more involved repair. For a closer look at what’s happening inside a well, video well inspections can identify issues inside the casing that aren’t visible any other way.

For pump-specific concerns, the water pump repair services offered by Accurate Drilling Solutions cover everything from submersible pump failures to pressure tank issues and control panel problems.

Assuming All Drillers Are the Same

Irrigation well drilling in Florida requires a licensed water well contractor. The licensing exists because drilling into the Floridan Aquifer system has real environmental and safety implications — improper casing, incorrect grouting, or a poorly placed well can introduce contaminants into the groundwater or damage the aquifer structure.

When selecting a driller for a Largo irrigation system, verify their state licensing, ask about their experience with the local geology, and confirm they handle the permitting process. If you want to review the kind of work that goes into a properly completed well project, the work photo gallery from Accurate Drilling Solutions shows real installations across the region.

Taking the time to vet your well contractor carefully is not overcautious — it’s the right call when you’re making an investment that’s meant to last decades.

Frequently Asked Questions

Do I need a permit for an irrigation well in Largo, Florida?

Yes. A Florida irrigation well permit is required before any new irrigation well can be drilled in Largo or anywhere in Pinellas County. The permitting process typically involves the Southwest Florida Water Management District. Working with a licensed well contractor means the permit process is handled as part of the project, keeping you in compliance from the start.

How do I know if my well pump is running dry?

Common signs of a well pump dry run include rapid pump cycling, a significant drop in pressure at the sprinkler heads, unusual motor sounds, or the system shutting down unexpectedly. If you notice any of these symptoms during irrigation, shut the system down immediately and contact a licensed well service professional to assess the water level and pump condition before running it again.

How often should an irrigation well be serviced?

Most irrigation wells benefit from an annual inspection that covers pump performance, pressure output, water quality, and the physical condition of the well casing and cap. Properties with heavier irrigation demand or older systems may benefit from more frequent check-ins. A maintenance agreement is an easy way to keep service intervals consistent without having to track them yourself.

What causes orange or yellow staining from my irrigation system?

Staining on driveways, fences, and exterior walls is typically caused by elevated iron content in the well water. This is a common issue in Florida’s limestone aquifer system. Beyond aesthetics, iron-rich water can clog sprinkler heads and reduce system efficiency over time. A water quality test can confirm the cause and help determine the right treatment approach.

Can I add more irrigation zones to my existing well system?

Adding zones is possible, but it requires evaluating whether the existing pump can handle the increased demand. Pump capacity is matched to a specific flow rate and pressure requirement. Adding zones without upgrading the pump can lead to underperformance across the entire system. Have a qualified well professional assess the current setup before expanding the zone count.

What should I do to prepare my irrigation well for hurricane season?

Before storm season, make sure your system has surge protection on all electrical components. Check that the well cap and casing are secure and undamaged. If your area is prone to extended power outages, discuss backup power options with a well service professional. A pre-season inspection is also a good opportunity to identify any components that may be vulnerable to storm-related stress.
