Hard water in Apopka and what scale does to heaters and fixtures
The City of Apopka's 2025 water quality report calls its water moderately hard. Recent tests ran from 120 mg/L to 200 mg/L, which is 7.0 to 11.7 grains per gallon. Water in that range leaves mineral scale on heating elements, tank bottoms, showerheads and faucet aerators.
Scale makes a water heater work harder and can shorten the time before it needs service. A tank that rumbles or pops as it heats is a common sign, and water heater repair usually begins with flushing and testing it. Your own tap may sit above or below the city range, so a home test kit tells you more.
Tankless units are sensitive to scale because water passes through narrow channels. In hard water they are normally descaled on a schedule, and the maker's manual sets the interval. If your tankless water heater throws errors or runs cold, scale is one of the first things to check.
Hard-water symptoms around the house and what to do about them
Not every symptom is scale. This table shows what it usually means and what a plumber looks at.
| What you see | What it often means | First step |
|---|---|---|
| White crust on faucets and showerheads | Mineral scale left as water dries | Clean or replace aerators and heads, then test the tap |
| Water heater rumbles or pops | Scale layer on the tank bottom | Have the tank checked and flushed |
| Tankless unit shows errors or runs cold | Scale in the heat exchanger | Descale per the maker's manual, then recheck |
| Flow drops at one faucet only | Clogged aerator or cartridge | Remove and clean it before assuming a pipe problem |
| Scale returns soon after cleaning | Hardness is steady at the source | Ask about a softener or filter |
A softener helps with scale but is not a fix for a failing heater.
Scale, leaks or a backed-up kitchen line?
Call the 24/7 line and tell dispatch whether it is a home or a restaurant, and what the water is doing.
Reclaimed irrigation: a second water system in your yard
Apopka's reclaimed program delivers about 8 million gallons a day to over 9,300 homes and businesses, and the city has run reuse for almost 50 years. Reclaimed water is treated wastewater meant for irrigation, not for drinking. If your sprinklers run on it, never tie that line into the house plumbing.
The city also runs a cross-connection program, which exists to keep irrigation and drinking water apart. A plumber doing any work near the meter or the irrigation tie-in should ask which water your yard uses. If you are not sure, call the city utility on 407-703-1731 before you touch the lines.
Grease, restaurant drains and the city program
Apopka runs a City Oil and Grease Management Program under Ordinance 3152. It has separate pages for residential and non-residential properties, and certificates go through the city's OpenGov portal. Restaurants and food businesses should read the city's rules and confirm what applies to their kitchen.
Grease is also what clogs most kitchen lines, at home or in a restaurant. Drain cleaning clears the blockage but does not replace the upkeep the city program asks for. A kitchen drain that backs up during service is an emergency, and our 24/7 line is open for it.
Apopka plumbing emergency: what to do before we arrive
Call our 24/7 line, then work through the case that matches yours.
Water flooding from a line
Close the main valve where the supply enters the house and open a low faucet. If the water is reclaimed irrigation water, keep children and pets away from it.
Kitchen drain backing up
Stop the dishwasher and sinks. Do not pour grease or chemical opener down the line, and tell dispatch whether it is a home or a restaurant.
Heater leaking or no hot water
Turn off the heater's power at the breaker and the cold water feed. If you smell gas, leave first and call 911 or the gas utility.
Trouble at the street or meter
That is the city's side. Apopka lists 407-703-1757 as its Public Works emergency line. If you cannot tell which side the leak is on, call us and we will help sort it.
After hours, dispatch decides with you whether the job needs a visit tonight. Lower-urgency work, such as a scaled-up faucet, can usually be booked as a same-day appointment when available.
Downtown 32703, the rest of 32712 and the neighborhoods between
The Town of Apopka plat was recorded in 1886. Downtown has Apopka Station on the West Orange Trail at 111 S Forest Ave and Tom Staley Historical Park at 211 E Third St. City hall at 120 E Main St sits in ZIP 32703. Older downtown lots may hold older plumbing, so a plumber confirms the house's age on site.
Most of the rest of the city falls in 32712. Subdivisions inside the city include Errol Estates, Kelly Park Hills, Rock Springs Ridge, Sheeler Oaks, Piedmont Lakes, Pines of Wekiva, Wekiva Run, Bluegrass Estates and Lake Doe Cove. We do not know build years for them, so we never guess a home's age from the subdivision name.
City utility, permits and dispatch from Ocoee
The city draws from 13 wells and runs five treatment plants, serving about 97 percent of Apopka. For billing or water quality, use the city utility. For anything inside your walls, Ocoee Express Plumbing dispatches licensed plumbers from 300 W Franklin St in Ocoee.
Permits go through the Building-Safety Department at 120 E Main St, 2nd floor, 407-703-1713. Applications run through the city's OpenGov portal, with trade-specific forms for subcontractors. Ask Building-Safety whether your job needs a permit, since rules vary by work.
The drive from Ocoee is about 10 miles and 14 minutes via SR 429 and US 441, an estimate that is not an arrival time. Pine Hills lies east of Ocoee, so neighbors there should read our Pine Hills page. Winter Garden to the west has its own water and permit offices on its own page.
What Apopka homeowners ask about water, ZIPs and urgent calls
Apopka has two delivery ZIPs, 32712 and 32703. By area, 32712 covers a bit over half the city, and 32703 covers most of the rest, including downtown and city hall.
A small part of Ocoee also lies in 32703, so that ZIP alone does not mean Apopka. The PO Box ZIP 32704 is not a place we can drive to, so give a street address.
Yes. Our 24/7 line takes emergency calls day and night, and dispatch sends licensed plumbers for floods, sewage backups and leaking water heaters.
Less urgent jobs can often be booked as a same-day appointment when available. A clear price comes before work starts.
The city's 2025 report calls it moderately hard. Recent tests ran from 120 mg/L to 200 mg/L, or 7.0 to 11.7 grains per gallon.
Your tap can differ from the city range, so test it. Ask about a softener only if scale keeps coming back.
Not by itself, but scale in the narrow channels can cause errors and cold output. Descaling on the maker's schedule helps limit it.
If yours already acts up, ask a plumber about tankless service before you replace the unit.
No. Reclaimed water is treated wastewater for irrigation, and the city runs a cross-connection program to keep it separate from drinking water.
Call the city utility on 407-703-1731 if you are unsure which water your yard uses.
Often, yes. Apopka's City Oil and Grease Management Program, under Ordinance 3152, covers non-residential properties, so confirm the rules for your kitchen with the city.
We can clear the line through drain cleaning, but the city program sets the upkeep rules.
