Water Heater Repair
Water heaters in cold spaces can suffer supply line freeze damage.
When the temperature drops and a faucet only sputters, water inside a pipe has likely turned to ice. We thaw lines safely, find and repair any section that split, and protect the runs most exposed to the cold so it does not happen again next winter.
Water expands as it freezes. In a closed pipe, that expansion builds pressure between the ice and the closed faucet, and the pipe often splits in a section that never looked frozen at all.
Pipes freeze where cold air reaches them: along exterior walls with thin insulation, in crawlspaces with open vents, in unheated garages, in attics, beneath kitchen sinks on outside walls and at hose connections. Wind makes the problem worse by pulling cold air through small gaps around rim joists, foundation vents and utility penetrations. A single bitterly cold night can freeze a line that has been fine for years if the wind direction or a new gap changes the conditions.
The first sign is usually a faucet that delivers only a trickle or nothing at all while other fixtures work normally. Frost on an exposed pipe, a bulge in the line or a toilet that does not refill are other clues. At that point the goal is to thaw the pipe gradually and to be ready for a leak, because a split often reveals itself only when the ice melts and pressure returns.
Safe thawing starts by opening the affected faucet so melting water and steam have somewhere to go. Heat is then applied slowly from the faucet end back toward the frozen section using tools such as warm air, heat lamps kept at a safe distance, or pipe thawing equipment designed for the purpose. Open flames, torches and propane heaters are never used on frozen pipes because they can ignite building materials, damage pipe and fittings, and create carbon monoxide in enclosed spaces.
When a line has already burst, the priority is stopping the water. Knowing where the main shutoff valve is located can save thousands of dollars in damage. Once the water is off, we locate the damaged section, which may be inside a wall, ceiling or crawlspace, and repair it with materials appropriate to the existing piping. Copper, PEX and CPVC each require different fittings and techniques, and the repair is pressure tested before the wall is closed or the area left.
Repair alone does not prevent the next freeze. After the immediate problem is resolved, we look at why that section froze. Solutions may include insulating the pipe, sealing air leaks near it, rerouting the line away from an exterior wall, installing frost-proof hose bibs that keep water inside the heated space, or adding self-regulating heat cable listed for use on water pipes where rerouting is impractical.
Homeowners dealing with water damage should photograph the affected areas before cleanup when it is safe to do so. Insurance policies differ, and documentation of the damage and the repair can help if a claim is filed.
Recognizing these signs quickly can limit damage.
If other fixtures work normally, the line feeding that faucet may be frozen somewhere along an exterior wall or unheated space. Open the faucet slightly and call for help before trying to heat anything.
Visible frost, a bulge or a split in a pipe indicates freezing. Do not strike or twist the pipe, since frozen piping can crack further under stress.
A pipe that split while frozen often starts leaking once temperatures rise. Stains on ceilings or walls after a cold spell deserve immediate attention.
When supply and drain lines in the same area freeze, odors can appear because water is not moving through traps normally.
An unexplained jump in the water meter reading during or after a freeze can reveal a hidden leak.
A toilet on an exterior wall that stays empty after flushing may have a frozen supply line.
Safety, water control and a lasting fix, in that order.
We confirm the location of the main shutoff and close it if a leak is present or likely.
Exposed runs, exterior walls, crawlspaces and hose connections are checked to find the ice.
Controlled heat is applied from the open faucet back toward the frozen area, never with open flame.
Damaged sections are exposed, cut out and repaired with fittings suited to the existing pipe material.
Water is restored slowly and the repaired line is checked for leaks under normal pressure.
We recommend insulation, air sealing, rerouting, frost-proof hose bibs or listed heat cable as appropriate.
Every frozen pipe call covers these steps.
Thawing a frozen line with no damage is the simplest scenario. Costs rise when a pipe has burst, especially if the break is inside a finished wall or ceiling, beneath a floor or in a tight crawlspace that is difficult to reach.
Material and location matter as well. Copper repairs require soldering or press fittings, PEX repairs use crimp or expansion fittings, and older galvanized piping may need a larger section replaced because it cannot be joined easily. Nights and weekends during cold snaps are our busiest times, and any after-hours rate is shared before dispatch.
Prevention work such as insulation, heat cable, frost-proof hose bibs or rerouting is quoted separately after the emergency is resolved, so you can decide calmly what protection makes sense.
Water damage restoration, drywall and flooring replacement are separate from plumbing repairs. We tell you what we see so you can involve the right restoration professionals and your insurer.
Frozen pipes are stressful, especially in the middle of a cold night. Our dispatchers stay calm, walk you through shutting off the water if needed and send a technician equipped for thawing and repair.
Since 2011 we have helped Kyle, TX households through winter plumbing emergencies. Our technicians never use open flames on frozen pipes, and they explain what caused the freeze so you can prevent it next time.
After the repair, we look at the whole path of the affected pipe, because the same cold air that froze one spot may be threatening another nearby.
A little preparation before and during cold weather protects your plumbing.
Leaving the thermostat at a moderate setting, often suggested around 55 degrees Fahrenheit or higher, helps keep interior pipes above freezing.
Letting warm room air reach pipes under kitchen and bathroom sinks helps protect them on very cold nights.
A slow drip during extreme cold keeps water moving and relieves pressure if ice begins to form.
Hoses left connected can trap water in the hose bib and cause it to freeze and split.
Foam pipe insulation in crawlspaces, garages and basements slows heat loss.
Mark it clearly and make sure everyone in the household knows how to close it.
What homeowners ask during and after a freeze.
If the pipe is accessible and not leaking, gentle warm air from a hair dryer, with the faucet open, can help. Never use open flames, and stop immediately if you see water leaking. Call for help if the frozen section is hidden or you are unsure.
The split often occurs while the pipe is frozen, but water only escapes once the ice melts and pressure returns. That is why leaks commonly appear during the thaw.
It is often where the water line enters the home, such as a basement wall, crawlspace, utility room or near the water heater. Some homes also have a curb stop near the street that the utility controls.
PEX tubing can tolerate some expansion better than rigid pipe, but it can still freeze and fittings can fail. Protection is important for every material.
It is an outdoor faucet designed with its shutoff valve inside the heated part of the house, so water is not left sitting in the section exposed to cold.
Heat cable listed for water pipes and installed according to the manufacturer's instructions can protect vulnerable runs. Using the wrong product or covering it improperly can create hazards.
Coverage varies by policy and circumstances. Photographs, repair records and prompt action help when discussing a claim with your insurer.
Comments from customers after winter plumbing emergencies.
Our kitchen faucet stopped working on the coldest night of the year. The technician thawed the line safely and added insulation where cold air was getting in behind the cabinet.
A pipe burst in our crawlspace. The dispatcher helped me find the shutoff, and the repair was finished that morning.
They replaced our old outdoor faucet with a frost-proof model, and it has not frozen since.
