Plumbing notes

Carlo DeLuca on condensate lines, overflow pans, and the leaks people treat as an HVAC problem.

Coastal Florida air-handler closet with metal overflow pan holding water and a white float switch mounted high above the water line, PVC lines above, palm light through the open door

The Closet Float Never Cut the Coil

The pan was full. The unit was still running. The float switch never saw the water. Check the height before you open the PVC.

Coastal Florida air-handler closet with white PVC condensate trap that holds no water after a quiet week

The Closet Trap Went Dry After the Quiet Week

The unit sat. The trap dried. The pan held water the next morning. Prime the condensate trap before you chase the line.

Coastal Florida air-handler closet showing white PVC condensate pipe running uphill from the coil, with standing water in the metal overflow pan

The Primary Line Pitched Back to the Coil

The outdoor dump was dry. The closet pan was not. The primary PVC line pitched the wrong way and sent condensate back into the pan.

Read note
Coastal Florida air-handler closet with a white condensate pump, a clear check valve on the discharge hose, and standing water in the metal overflow pan

The Check Valve Failed and the Pan Refilled

The pump emptied the pan. By morning it was full again. The check valve on the discharge hose had failed and let the line siphon back.

The Condensate Pump GFCI Tripped Overnight

The hallway felt cool. The pan under the coil was a pond. The pump was dry because the outlet had tripped while you slept.

Read note
Beige coastal Florida stucco with a chrome outdoor shower valve and riser, a dark wet streak under the escutcheon, and a puddle on the concrete pad in palm shade

The Outdoor Shower Wept Into the Stucco

The pad was still dark after the rinse. The streak left the valve escutcheon, not the eave.

The Expansion Tank Wept at the Tee

The pan had a film. The relief pipe was dry. The drip left the brass tee under the small tank on the cold line.

The Closet Supply Line Sweated Into the Pan

The Sprayer Hose Split Under the Sink

The dishwasher hose was dry. The gray coil under the pull-down faucet was not. An October Saturday cook left a wet patch on the cabinet floor.

Blue whole-house filter housing on a coastal Florida garage wall with a drip at the cap seam, a wet patch on the slab, a dry condensate pump beside it, and palms through the open door

The Filter Housing Wept on the Slab

Read note
Coastal Florida laundry with a utility sink holding a clear condensate pump hose and a gray washer drain hose, a pump on wet tile, and palms outside the window

The Utility Sink Took Both Hoses

The closet was dry. The utility sink held the pump hose and the washer drain. Both dumped, and the tile paid.

Read note
Coastal Florida kids bathroom with a white toilet tank beaded in condensation and a small puddle on beige tile beside a blue step stool

The Kids-Bath Tank Wept on the Tile

The hall felt fine. The tank wept on the tile. Porcelain sweat is water on the floor, not overnight rain in the bunk.

Read note
Coastal Florida workout room with a white portable machine hose ending in a puddle on black rubber gym mats, utility sink unused in the next doorway

The Workout Hose Never Reached the Sink

The hall felt fine. The hose sat in a puddle on the mat. A dump that never reached the sink is a drain, not morning sweat.

Read note
Coastal Florida crawlspace with a white PVC condensate hose ending in a wet dirt puddle instead of a daylight dump

The Crawl Dump Never Made Daylight

The dining room felt fine. The crawl hose sat in its own puddle. A dump that never left the dirt is a drain, not Sunday steam.

Read note
Coastal Florida soffit with a short white PVC secondary drain stub and a faint stain on the stucco below

The Soffit Secondary Never Dripped

The closet felt fine. The secondary stub at the soffit stayed dry. A quiet warning pipe is a drain, not Saturday air.

Read note
Coastal Florida garage with a white air handler on a metal stand and a full condensate pump overflowing onto wet concrete

The Garage Pump Sat in Its Own Water

The bonus room felt fine. The pump under the garage handler sat in a puddle. A full reservoir is a drain, not Saturday air.

Read note
Coastal Florida guest bedroom with a wall mini-split, a stained PVC drain, and a puddle on the tile at the baseboard

The Mini-Split Line Wept on the Wall

The hallway felt fine. The guest-room wall had a tea stain under the cassette. A wall drain is not overnight bath air.

Read note
Coastal Florida attic with a metal air-handler overflow pan holding water and a dark stain spreading across plywood decking

The Attic Pan Stained the Ceiling

The hallway felt fine. The bedroom ceiling had a tea stain. An attic pan is a drain, not a night setback.

Read note
Coastal Florida laundry alcove with a white PVC standpipe overflowing onto stained concrete beside a front-load washer

The Laundry Standpipe Spit on the Slab

The hallway felt fine. The standpipe spit suds on the slab. A drain pipe is not a wet basket.

Read note
Coastal Florida screened porch with a brass hose bib dripping onto wet beige tile beside a slider

The Florida Room Hose Bib Wept on the Tile

The hallway felt fine. The Florida-room tile under the bib was a puddle. A hose bib is a pipe, not afternoon rain on the screens.

Read note
Coastal Florida garage with a wall-mounted tankless water heater dripping condensate into a white paint bucket on wet concrete

The Tankless Sat Over a Paint Bucket

The tankless still made hot water. The paint bucket under the tube was half full. A bucket is not a drain.

Read note
Coastal Florida air-handler closet with a white PVC P-trap stained green over a metal overflow pan

The Closet Trap Sat Green

The outdoor dump looked open. The U-bend under the coil was green. A slimed trap fills the pan while the hallway still feels cool.

Read note
Open Florida kitchen cabinet with a corrugated dishwasher drain hose and a dark wet stain on the particle-board floor

The Dishwasher Hose Sat in the Cabinet

Breakfast was over. The cabinet floor was dark. A slipped dishwasher hose soaks particle board long before the hallway smells it.

Read note
White PVC condensate elbow leaving a Florida stucco wall and ending in wet brown mulch

The Condensate Elbow Sat in the Mulch

The closet pan looked honest. The outdoor elbow was under last week's mulch. A dump you cannot see is a drain you will trust too long.

Read note
Florida condo plumbing chase with white PVC stack and a stained baseboard on tile

The Condo Stack Wept at the Baseboard

The hallway felt fine. The chase door was dark at the floor. A shared stack is a pipe, not a humidity reading.

Read note
Florida laundry pair on a slab with dark rubber supply hoses and a small puddle at the wall

The Washer Hose Softened on the Slab

The cycle finished. The slab behind the box was dark. A tired washer hose weeps where nobody looks until the baseboard swells.

Read note
White Florida garage water heater standing in a metal overflow pan with a capped drain stub and standing water

The Heater Pan Had Nowhere to Go

The tank looked fine. The pan was a puddle with no pipe. A heater pan with nowhere to go is a bucket with a reputation.

Read note
Florida kitchen fridge with a thin ice-maker line and a dark wet kickplate on tile

The Fridge Line Wept Into the Kickplate

The ice maker still clicked. The kickplate was dark. A fridge line weeps into particle board long before the hallway smells it.

Read note
White PVC condensate drain and trap on a Florida air-handler cabinet

The Closet Drain Had No Fall

The PVC looked fine. The reservoir was full. In a closet with no downhill run, the pump is the drain.

Read note
Florida water-heater closet with copper lines and a bronze circulator on the loop

Hot Water Without the Five-Minute Wait

Convenience is real. So is a 24/7 loop. Timer or a button. Do not pay to keep pipes hot while you sleep.

Leak sensor puck beside Florida washing-machine supply hoses

Five Places a Leak Puck Earns Rent

A five-pack is not a hobby. It is the rooms that ruin a Saturday if nobody is home to hear the hiss.

Leak sensor sitting in a wet Florida air-handler overflow pan

The Overflow Pan Should Text You

The float switch is a kill switch. The leak puck is a witness. You want both in a Florida closet.

Your Phone Knows Before the Ceiling

The future is not a gadget catalog. It is a text that the pan is wet while you are still at Publix.

Florida closet with wet baseboard after an indoor leak

The AC Was Cool. The Closet Was Dripping

The air felt fine. The overflow pan did not. In Florida the AC is a water machine. Treat the drain as the job.
