The Florida Homeowner Plumbing Maintenance Checklist (Sarasota & Charlotte County)

Florida is a great place to own a home. It is also a place where your plumbing works harder than it would almost anywhere else in the country.

Hard water, high humidity, year-round heat, hurricane season, and aging infrastructure in many neighborhoods create a combination of stresses that accelerate wear on pipes, fixtures, water heaters, and water treatment equipment.

The good news: most plumbing problems are preventable. A consistent maintenance routine catches small issues before they become expensive ones.

This checklist is organized by frequency — monthly, quarterly, and annually — and is tailored specifically to the conditions in Sarasota and Charlotte County.

Open the cabinet under each bathroom and kitchen sink and look for:

• Moisture, water stains, or discoloration on the cabinet floor
• Drips or slow leaks at supply line connections
• Corrosion on shut-off valves or drain connections
• Musty odor (a sign of hidden moisture)

Slow leaks under sinks are one of the most common sources of water damage in Florida homes. They are easy to miss because the cabinet door is usually closed — and by the time you notice a problem, mold may already be growing.

Turn on every faucet, shower, and tub drain in the house and observe:

• Is the water draining quickly or slowly?
• Any gurgling sounds from drains?
• Any odors coming up from drains?

Slow drains are early warning signs of partial clogs. Gurgling sounds can indicate a venting issue or a blockage further down the line. Catching these early is far less expensive than a full drain cleaning or camera inspection later.

For each toilet:

• Flush and observe — does it flush completely and refill properly?
• Listen after flushing — does the fill valve shut off completely, or does it run intermittently?
• Check for any movement or rocking at the base
• Look for water around the base of the toilet

A running toilet can waste 200 gallons of water per day. In Florida, where water bills are already significant, a running toilet adds up quickly. Most running toilet issues are a $10–$30 fix if caught early.

Look at the braided stainless or plastic supply lines connecting shut-off valves to toilets and faucets. Look for:

• Bulging or blistering (a sign of imminent failure)
• Corrosion at the fittings
• Any moisture or mineral deposits around connections

Supply line failures are one of the most common causes of sudden, significant water damage in homes. They can fail without warning — but visible deterioration usually precedes failure.

Turn each shut-off valve under sinks and behind toilets off and back on. In Florida's humid environment, valves that are never operated can seize up over time — meaning when you actually need to shut off water in an emergency, the valve will not turn.

If a valve is stiff, do not force it. A seized valve is better replaced proactively than broken during an emergency.

Whether you have a tank or tankless water heater:

Tank water heaters:

• Look for rust, corrosion, or moisture around the base and connections
• Check the temperature and pressure (T&P) relief valve — there should be no dripping or discharge
• Listen for popping or rumbling sounds during heating (a sign of sediment buildup)
• Verify the temperature is set to 120°F (hot enough to prevent bacterial growth, low enough to prevent scalding)

Tankless water heaters:

• Check for error codes on the display
• Look for any moisture around connections
• Verify the inlet filter screen is not clogged (check annually or more often with well water)

If you have a water softener:

• Check the salt level in the brine tank — it should be at least one-third full
• Look for salt bridges (a hard crust that forms above the water level, preventing proper regeneration)
• Check the bypass valve is in the service position
• Look for any error indicators on the control head

If you have a whole home filtration system:

• Note the date your filters were last changed
• Check for any leaks at filter housing connections
• If your system has a pressure gauge, verify pressure drop across the filter is within normal range

If you have a reverse osmosis system:

• Check the storage tank pressure (should be 7–8 PSI when empty)
• Note filter change dates
• Verify the dedicated faucet is flowing at normal rate (slow flow indicates a filter or membrane that needs replacement)

Florida homeowners use outdoor water connections year-round. Quarterly, check:

• Hose bib connections for drips or leaks
• Irrigation system heads for clogs, misalignment, or damage
• Any signs of water pooling near the foundation (can indicate a slow leak in an irrigation line)

Florida water conditions change. Municipal water treatment practices vary seasonally. Well water quality can shift over time.

An annual water test gives you a current picture of:

• Hardness levels (important for sizing and maintaining softeners)
• Chlorine and chloramine concentrations
• pH and TDS
• Any contaminants specific to your water source

We offer free in-home water testing throughout Sarasota and Charlotte County. It takes about 30 minutes and gives you a clear baseline for your water treatment decisions.

Tank water heaters: Flush the tank annually to remove sediment that accumulates at the bottom. Sediment reduces efficiency and accelerates corrosion. In Florida's hard water, sediment buildup is faster than in softer water regions.

Tankless water heaters: Have the unit professionally descaled annually. In Sarasota and Charlotte County's hard water environment, this is not optional — it is the single most important maintenance task for extending the life of a tankless unit.

Know where your main water shut-off is and verify it operates properly. In an emergency — a burst pipe, a failed supply line, a plumbing disaster — you need to be able to shut off water to the entire house immediately.

If your main shut-off is a gate valve (an older style with a round handle that requires multiple turns), consider having it replaced with a ball valve (a quarter-turn lever). Gate valves are more prone to seizing and less reliable in emergencies.

This is one of the most useful annual checks you can do:

1. Turn off all water in the house — no faucets, no appliances, no irrigation
2. Note the reading on your water meter
3. Wait 30 minutes without using any water
4. Check the meter again

If the meter has moved, you have a leak somewhere in the system. Even a small leak — a dripping faucet, a slow toilet, a pinhole in a pipe — will show up on the meter.

In Florida, many homes have plumbing routed through the attic — especially in homes built in the 1980s and 1990s. Attic temperatures in Sarasota can exceed 140°F in summer, which accelerates wear on older copper and CPVC pipes.

Annually, inspect any accessible pipes for:

• Corrosion or green discoloration on copper pipes
• Cracks or brittleness in CPVC (it becomes brittle with age and heat)
• Loose or missing pipe insulation
• Signs of previous leaks (water stains on insulation or framing)

If your home has copper pipes that are 20+ years old, or CPVC that is showing signs of brittleness, it may be worth having a licensed plumber assess the condition of your plumbing system.

Once a year, having a licensed plumber walk through your home and assess the overall condition of your plumbing system is one of the best investments you can make. A professional inspection can identify:

• Aging pipes that are approaching end of life
• Water pressure issues (high pressure accelerates wear on fixtures and supply lines)
• Water heater condition and remaining lifespan
• Drain line condition (camera inspection if warranted)
• Any code compliance issues

The cost of a professional inspection is a fraction of the cost of a burst pipe, a failed water heater, or a slab leak.

Before hurricane season:

• Know where your main water shut-off is and verify it works
• Have a licensed plumber's number saved in your phone
• If you have a well, check your pump and pressure tank condition
• Consider a whole-home surge protector if you have electronic water treatment equipment

Every day that hard water flows through your pipes, fixtures, and appliances, it is depositing minerals. The best maintenance you can do for your entire plumbing system is treating the water before it enters your home. A properly sized water softener reduces scale buildup in pipes, extends appliance lifespans, and makes every other maintenance task easier.

Many Sarasota and Charlotte County homes built before 2000 have copper plumbing. Florida's aggressive water chemistry — particularly in areas with low pH or high chloramine levels — can cause pinhole leaks in copper pipes over time. If you are seeing unexplained water stains on walls or ceilings, or your water bills are creeping up without explanation, have a plumber assess your copper pipes.

Some maintenance tasks are DIY-friendly. Others require a licensed professional. Call a plumber when:

• You find evidence of a leak but cannot locate the source
• A shut-off valve will not turn or is leaking
• Your water heater is making unusual noises, showing error codes, or is more than 10 years old (tank) or has never been serviced (tankless)
• You have low water pressure throughout the house
• Multiple drains are slow simultaneously (indicates a main line issue)
• You see signs of corrosion on pipes or fittings
• Your water has changed in taste, smell, or appearance
