If you notice your shower pressure dropping or your faucets running weaker than usual in the spring, you are not imagining it. Seasonal pressure fluctuations are common across Naples, Bonita Springs, and the surrounding Southwest Florida communities, and several specific causes tend to cluster around the spring months.
At A-1 Plumbing & Gas, we field a noticeable uptick in plumbing repair and water pressure calls every spring. Here is what is usually behind it.
Spring in Southwest Florida means snowbirds are still here, tourist season is at its peak, and seasonal residents are running irrigation systems full-time. Municipal water systems in Collier and Lee County see elevated demand during this period, which can result in lower line pressure reaching your home.
If your pressure drop is slight and affects the whole neighborhood at certain times of day, demand is likely the cause. It typically improves as seasonal residents leave and summer demand normalizes.
Most homes in Collier and Lee County have a pressure reducing valve (PRV) installed where the main water line enters the house. This regulator steps down the incoming municipal pressure to a safe level for your home's plumbing, typically 50 to 80 PSI.
PRVs have a lifespan of 10 to 15 years. When they begin to fail, they either restrict pressure too much (low pressure throughout the home) or stop regulating (too-high pressure that can damage fixtures). A failing PRV is one of the most common causes of sudden, whole-home pressure loss.
Replacing a PRV is a relatively quick job for a licensed plumber. If your home's pressure was fine last year and has dropped noticeably this spring, the regulator is a strong suspect.
Florida's fast-growing tree and shrub root systems actively seek water during the dry season (which peaks in late winter and early spring). Roots frequently infiltrate sewer and water lines at joints and fittings, restricting flow and causing pressure loss.
If you have mature landscaping between the street and your home, and your pressure loss is gradual rather than sudden, root intrusion in the main water line is worth investigating. A water line inspection with a camera can confirm this quickly.
Florida's hard water deposits calcium and magnesium inside pipes, fixtures, and appliance connections over time. Shower heads and aerators are the most common victims, they clog with mineral scale and restrict flow noticeably. If the pressure issue is limited to one fixture, start by cleaning or replacing the aerator or shower head.
If buildup is occurring throughout the home's supply lines, a whole-home water filtration system or softener addresses the root cause and protects your plumbing long-term.
A gradual pressure drop across the home, not tied to usage patterns or time of day, can indicate a slow leak in the main supply line or a slab leak. If your water bill has also increased, a hidden leak detection visit is a smart next step.
Start by testing your pressure with an inexpensive gauge that threads onto a hose bib. Normal residential pressure is 40 to 80 PSI. If you are below 40, call a plumber to check the regulator and main line. If you are above 80, a new PRV is needed to protect your fixtures and appliances.
