How to prevent frozen pipes in Tampa (yes, it happens)

Why Tampa pipes are more vulnerable than you'd think

In cold-climate homes, plumbing runs inside the insulated building envelope, protected from freezing temperatures. Tampa homes? Built for heat. Supply lines run through uninsulated attics, along exterior walls with barely any insulation, through crawlspaces and carports with zero freeze protection. Outdoor hose bibs, irrigation backflows, and pool equipment are completely exposed.

So when Tampa does get a hard freeze (typically 2-4 nights per winter, occasionally a multi-day cold snap), the pipes at risk have absolutely no protection. Homes up north have pipes buried 4 feet deep and insulated inside walls. Your Tampa home might have bare copper running through the attic with nothing around it.

Which pipes are most at risk

Pipes in unheated attics and attic crawlspaces. Pipes in exterior walls, especially on the north side. Outdoor hose bibs, irrigation backflow preventers, and pool equipment. Pipes in garages, carports, and screened porches. Any exposed run with no insulation.

Material matters too. Copper freezes faster than PVC or PEX because metal conducts heat away from the water. Smaller diameter pipes (1/2-inch supply lines) freeze before larger ones. And pipes with standing water (no flow) freeze before pipes where water is moving.

How to protect your plumbing before a freeze

Insulate exposed pipes in attics, crawlspaces, and exterior walls with foam pipe insulation sleeves. They cost about $1-$3 per 6-foot section at any Tampa hardware store and take a few minutes to install. Focus on any pipe running through an uninsulated attic.

Disconnect and drain garden hoses. If your home has an interior shut-off for outdoor hose bibs, close it and open the outside faucet to drain the line. Put insulated hose bib covers on exterior faucets. They're about $3 each.

Make sure you know where the main shut-off valve is and that it works. If pipes do freeze and burst, shutting off the water fast limits the damage. (See our guide on shutting off your water main.)

During a freeze warning

Let faucets drip. A slow drip on both hot and cold lines keeps water moving through the pipes, which significantly cuts freeze risk. Prioritize faucets served by pipes in vulnerable spots: exterior walls, attics, unheated spaces.

Open cabinet doors under kitchen and bathroom sinks on exterior walls to let warm indoor air reach the pipes. Keep the thermostat at a consistent temperature (at least 55 degrees) and don't turn the heat down at night during a freeze.

If you have a pool, run the pump continuously during the freeze. Moving water through the pump, filter, and heater prevents freeze damage. Most modern pool controllers have a freeze protection mode that kicks the pump on automatically when temperatures drop.

If your pipes freeze

If you turn on a faucet during a freeze and nothing comes out, a pipe is probably frozen. Do not use a torch or open flame to thaw it. That's a fire hazard and can crack the pipe. Use a hair dryer, heat lamp, or space heater pointed at the suspected frozen section. Apply heat slowly and evenly.

If you can't find the frozen section, or if you see signs of a burst (bulging pipe, crack, or water spraying when things thaw), shut off the main valve and call us at (813) 219-8764. We handle freeze-related pipe repairs 24/7 during cold snaps. Our burst pipe repair team can usually get to you within an hour during freeze events.
