Your Unit's Plumbing —
What Every Owner Should Know

Water damage is the single most expensive risk in a high-rise condominium. Understanding your unit's plumbing protects your investment, your neighbors, and the building as a whole.

🔧
Section 01

Your Main Water Shut-off Valve

Location: mechanical closet — usually near the water heater
Lever in line with the pipe = ON  •  Lever across the pipe = OFF

This valve controls all water entering your unit. In a flood — burst line, failed heater, ruptured connection — it's your only way to stop the water.

⚠️
If your valve is old, corroded, or stiff, it may not work when you need it. Replace proactively — it costs a fraction of a water damage claim.

Look for a modern quarter-turn ball valve. One quarter turn fully opens or closes flow. If yours is stuck or leaking around the stem, call a plumber.

Locate your valve today and confirm you can turn it.

Pressure Reducing Valve (PRV)

Controls the water pressure delivered to your unit
A healthy PRV holds your unit at 50–70 PSI. A failed one lets pressure spike.

Your PRV reduces incoming building water pressure to a safe level (50–70 PSI). Without it, every fixture in your unit is under excess stress and will wear out years ahead of schedule.

📈
A failed PRV can push 110+ PSI through your unit — damaging your water heater, faucets, supply lines, and washing machine hoses simultaneously.

Lifespan: 5–7 years. They can fail open (too high) or closed (too low). A plumber can test your pressure with a simple gauge.

Warning signs: banging pipes, fluctuating pressure, high water bills, or corrosion on the valve body.

💡
PRV replacement is straightforward and far cheaper than replacing fixtures damaged by chronic overpressure.

Water Heater Replacement at 10 Years

Insurance requirements, state law, and the real risk of aging tanks
Aging tanks corrode from the inside out — a small drip can become a flood overnight.

Water heaters must be replaced at or before 10 years. After that mark, tank rupture and leak rates increase dramatically.

$50,000$150,000+
Typical damage from a failed water heater in a condo unit — including units below

Insurance: Many policies require heaters under 10 years old as a condition of coverage. An out-of-compliance heater can be grounds to deny a claim entirely.

Florida law (SB 4-D): Buildings must maintain records of equipment age and condition. Water heater compliance is part of building-wide inspection programs that affect association insurance standing.

The risk: Aging tanks develop internal corrosion and thinning walls. A small leak becomes a catastrophic failure with no warning.

Don't know your heater's age? Check the serial number label — most manufacturers encode the date in the first few characters.

Toilets — Parts, Seals & Stability

Four separate issues, each with serious consequences
A silent flapper leak quietly drains water — and money — around the clock.

Running toilets waste money. A silent leak from tank to bowl loses 1–3 gallons per minute — thousands of gallons a month.

💧
Most toilet leaks are silent. A worn flapper leaks constantly, but the only sign is the toilet briefly "running" every 20–30 minutes. Many owners never notice.

Base seal failure. The wax ring under your toilet seals it to the drain. When it fails, flush water seeps into the subfloor invisibly. By the time you see warped floors or ceiling stains below, the damage is extensive. A simple fix when caught early — an expensive renovation if ignored.


A moving toilet is a failing toilet. Any rocking or shifting means a broken flange, missing bolts, or bad seal. Every movement makes it worse. If it moves, it needs attention now.

⛔ Signs of Trouble

Rocks or shifts. Water at the base. Soft or discolored flooring. Odor in the bathroom.

✅ What's Normal

Completely solid. No water at base. Clean caulk line. Tank refills once then goes silent.

Section 05

Keep Your Drain Traps Wet

Especially important in seasonal / unoccupied units
Unused drains dry out → the water seal disappears → sewer gas drifts in. Just run the tap!

Every drain has a U-shaped trap that holds water to block sewer gas. When a drain goes unused — common in seasonal Florida condos — the water evaporates and the seal is lost.

🦨
Dry traps are the #1 cause of mystery odors in seasonal condos. Foul smell after returning? Run water down every drain for 30 seconds — problem solved.

How to Do a Simple Toilet Dye Test

Takes 10 minutes — reveals silent leaks you'd never otherwise find
No tools, no plumber — just a few drops of dye and 15 minutes.

The simplest way to check for a silent toilet leak. No tools needed.

  1. Don't flush for 15–20 minutes. Let the tank settle.
  2. Lift the tank lid. Add dye tablets, food coloring, or a dye strip to the tank water. Do not flush.
  3. Wait 10–15 minutes.
  4. Check the bowl. Colored water = leaking flapper. Clear water = pass.
🔵
Use red dye if you have blue cleaning pucks in the tank — it's easier to distinguish.

A new flapper costs $10–$15 and takes 10 minutes to replace. It can save thousands of gallons per month.

Spotting Corrosion on Valves & Supply Lines

Florida's environment accelerates deterioration — know what to look for
A 60-second visual scan of your fittings twice a year catches most problems early.

Florida's heat, humidity, and hard water accelerate corrosion dramatically. What takes 20 years elsewhere can appear in 8–10 years here. A quick visual check prevents failures.

Where to look:

Toilet supply line & shutoff valve Under-sink shutoff valves (hot & cold) Washing machine water supply box Water heater connections Dishwasher supply connection Exposed pipe joints in mechanical closet

What to look for: Green buildup (corrosion), white chalky deposits (seeping), rust staining (metal degradation), or any moisture around connections.

⚠️
Washing machine hoses are under constant pressure — even when the machine is off. Replace rubber hoses with braided stainless steel. Inspect and replace every 5–7 years.

When in doubt, call a plumber. A service call costs far less than an uncaught failure.

Leak Detection Systems

Priceless protection for occupied and unoccupied units alike
Sensor spots the drip → your phone gets the alert → the smart valve shuts the water off.

Smart leak detection systems are brilliant — we've seen them save millions in damages!

Fully automated systems can be installed and operated from most Smart Home Apps. There are reputable installers and brands available. You can install your own system too, all you need are a few components (DIY instructions coming soon, contact Crystal if you're interested in having the instructions sooner). Automatic Smart shutoff valves have to be installed by a Plumber, you can DIY the rest.

🛡️
Fully automated systems: $3,500–$7,500 installed or $1,000–$2,000 DIY. Insurance companies are discounting around 5% annual policy for automated installations.
⚠️
Note: Flow-based valves not recommended in South Florida due to calcium buildup.

These systems are CHEAP insurance and peace of mind for you — and your neighbors!
