Irrigation Repair vs Replace in Bonita Springs: How to Tell What Your System Really Needs

LOCAL KNOWLEDGE

October in Bonita Springs marks the turn from daily summer rain to our long dry season, which runs roughly October through May. Your lawn and beds stop getting free water and start depending entirely on your irrigation system. That is when small problems — a cracked head, a sticky valve, low pressure on one zone — turn into brown patches, stressed palms, and HOA letters. The big question homeowners ask us is simple: can this be repaired, or do I need a whole new system? The honest answer is: most systems do not need to be replaced. Here is how to tell the difference.

Signs a repair will probably fix it

If the rest of the system is sound, these are usually repair jobs: one or two broken or tilted heads, a single zone that will not turn on because of a failed valve or solenoid, a controller that lost its programming after a power surge, or patchy coverage in one corner because the heads are clogged with sand or hard-water scale — very common in Bonita Springs. A leaking lateral line from a root or a mower strike is also a repair, not a rebuild, if the pipe around it is still flexible and in good shape. Fixing what is broken and re-checking pressure and coverage often gets a system running like it should for years more.

Signs replacement starts to make sense

Replacement — or at least replacing a major section — becomes the smarter money when problems are system-wide, not isolated. That includes pipe that has gone brittle and cracks every time it is touched, multiple zones failing at once, a controller and wiring so corroded that zones fire randomly, or a layout that never covered the yard correctly in the first place, with dry corners no head adjustment can fix. If you are paying for a repair every month or two and your water bill keeps climbing despite the fixes, add up those invoices: at some point you are funding a new system one emergency at a time, without ever getting one.

The 7 checks to run before anyone recommends replacement

A good irrigation tech should be able to show you why, not just tell you. Before anyone quotes a full replacement, these checks should happen: 1) Pipe condition — is the PVC brittle or cracked, or is the break isolated? 2) Roots — are roots crushing lines in one spot or throughout? 3) Valves — do valves open, close, and hold pressure, or are diaphragms and solenoids failing across zones? 4) Controller — does it hold a schedule and run each zone on command? 5) Wiring — is there corrosion at splices and in the valve box, common in our humid, sandy soil? 6) Pressure and coverage — is pressure even zone to zone, and are heads spaced to actually overlap? 7) Backflow — is the backflow preventer working and not leaking? If a company skips these and jumps straight to replacement, get a second opinion.

Bonita Springs specifics that matter

Local conditions change the math. Bonita Springs has sandy soil that drains fast, so run times and head spacing that work in heavier soil leave dry spots here. Hard water builds scale inside heads and valves faster than most homeowners expect. Many communities also have watering-day restrictions and HOA appearance standards, so a system that runs but leaves the front yard patchy is still a problem. And with reclaimed-water systems in some neighborhoods, filtration and clogged nozzles are a recurring maintenance item, not a sign the whole system failed.

What it typically costs

Every property quotes individually after a wet check, so treat these as typical ranges, not quotes: a single head or nozzle repair often falls in the $75–$175 range per visit depending on count and access; a valve or solenoid replacement commonly runs $150–$350 per valve; a new smart controller installed and programmed is often $300–$650. A full system replacement for a typical Bonita Springs home varies widely by lot size, zone count, and landscaping in the way — most full replacements land in the $3,500–$7,500+ range. A repair-first inspection that maps every zone is almost always cheaper than guessing.

Why October is the right time to check

Do this check now, not in January when the lawn is already stressed. A fall wet check — running every zone, flagging dry spots, and fixing heads, valves, and timing before the driest months — protects the sod and plantings you already paid for. It also lets you set a dry-season schedule that waters deeply and less often, instead of daily shallow watering that wastes water and encourages shallow roots.

The bottom line

In Bonita Springs, repair first unless the evidence says otherwise: brittle pipe throughout, system-wide valve and wiring failure, or a layout that never worked. Ask for the checks above, in writing, and keep any system that passes them. That approach saves most homeowners money — and it is the only honest way to sell irrigation work.

Frequently asked questions

How long should a sprinkler system last in Bonita Springs?

With basic maintenance, the underground pipe can last 15–20 years or more. Heads, valves, and controllers wear faster — expect heads and nozzles to need attention every few years and controllers to last roughly 7–12 years, especially with power surges and hard water.

How do I know if I have an irrigation leak?

Watch for unusually high water bills, soggy spots that never dry, a zone with low pressure, or heads that seep when the system is off. A wet check that runs each zone and inspects the valve boxes and backflow will usually find it quickly.

Can I just replace one zone instead of the whole system?

Often, yes. If one zone has brittle pipe, root damage, or bad coverage while the rest of the system tests well, replacing or reworking that single zone is a common, cost-effective middle option between a small repair and a full replacement.
