There is a wide range of plumbing issues a capable homeowner can handle independently — a leaky faucet, a running toilet, a slow drain that responds to a plunger. But there is another category of plumbing problems where the right move is to stop what you are doing, shut off the water if possible, and call a licensed plumber immediately. Attempting to DIY these situations without the right tools, training, or knowledge can turn a bad situation into a much worse one.
Christian Heating, Cooling, Plumbing & Electrical serves homeowners throughout Bucks County, Montgomery County, and Chester County with prompt emergency plumbing response. This guide covers the plumbing situations that always require a professional — what they are, what to do in the first moments, and why waiting or attempting a DIY fix can cost you significantly more than calling for help right away.
Know Where Your Main Water Shutoff Is Before an Emergency Happens
Before diving into specific emergencies, there is one thing every Southeastern Pennsylvania homeowner should know: the location of the main water shutoff valve for their home. In most homes, this valve is located where the water supply line enters the house — often in the basement near the foundation wall, in a utility room, or near the water meter.
In a plumbing emergency involving water flow, shutting off the main supply is almost always the first critical step. Knowing exactly where that valve is and confirming it works before an emergency occurs is one of the most valuable pieces of home maintenance preparation a homeowner can do. If you are not sure where your main shutoff is, a plumber can locate and identify it during any service visit.
Burst or Severely Leaking Pipes
A burst pipe is one of the most urgent plumbing emergencies a homeowner can face. Water at household pressure — typically 40 to 80 PSI — flows at a rate that can cause catastrophic damage to walls, ceilings, flooring, insulation, and personal belongings within minutes. A pipe that bursts in an unoccupied space can flood an entire floor before anyone notices.
In Southeastern Pennsylvania, burst pipes most commonly occur during and after extended cold spells when pipes in unheated areas — crawl spaces, garages, exterior walls — freeze and then rupture as the ice expands. A single Pennsylvania winter night with temperatures well below freezing is enough to freeze an inadequately insulated pipe.
What to do immediately: shut off the main water supply to the house, turn off the water heater to prevent it from running dry, open cold water faucets to drain the remaining water in the pipes, and call Christian Heating, Cooling, Plumbing & Electrical. Do not attempt to thaw a frozen pipe with an open flame — this is a serious fire hazard. A hair dryer or heating pad applied carefully is the safe approach for visible frozen sections, but if the pipe has already burst, the priority is stopping the water flow, not thawing.

Sewage Backup Into the Home
When sewage backs up into your home through floor drains, toilets, or bathtubs, it is both a plumbing emergency and a health hazard. Raw sewage contains bacteria, viruses, and other pathogens that pose genuine risks to anyone in contact with it. This is not a situation for DIY fixes or waiting to see if it resolves on its own.
The cause of a sewage backup is almost always a blockage or failure in the main sewer line — either from a clog, root intrusion, a collapsed pipe section, or a problem in the municipal line. None of these causes can be resolved without professional equipment. Stop using all water in the home immediately, keep children and pets away from the affected area, and call for emergency service.
If sewage has entered a living space, avoid contact with the water, wear rubber gloves and boots if you must move through the area, and document the damage with photographs for your homeowner’s insurance claim. Professional remediation of sewage-affected areas is strongly recommended even after the plumbing issue is resolved.
No Hot Water Combined With Unusual Sounds or Smells From the Water Heater
A water heater that has stopped producing hot water is not automatically an emergency — it may simply be a failed heating element, a tripped reset button, or a pilot light issue. But certain water heater symptoms require immediate professional attention because they indicate potentially dangerous conditions.
Call a plumber immediately if your water heater is:
• Making loud rumbling, popping, or banging sounds — these can indicate severe sediment buildup that is causing the tank to overheat, or in extreme cases, a condition that can lead to tank failure
• Leaking from the tank itself, not just a fitting — a leaking tank cannot be repaired and requires emergency replacement before it fails completely
• Showing signs of corrosion, rust-colored water, or a strong metallic smell — indicators of internal corrosion that compromises both the tank’s structural integrity and water quality
• Producing a rotten egg smell — in a gas water heater, this may indicate a gas leak rather than a plumbing issue, which requires immediate evacuation and a call to your gas utility
• The pressure relief valve is actively discharging water — this valve opens when pressure or temperature inside the tank reaches dangerous levels. If it is releasing water, the system has a serious pressure or temperature problem that needs immediate professional attention
Gas Line Leaks or Suspected Gas Leaks
A suspected gas leak is not a plumbing situation to investigate yourself. If you smell natural gas — a rotten egg or sulfur odor — in your home, leave immediately without turning any lights, switches, or appliances on or off. Once outside, call your gas utility’s emergency line and 911. Do not re-enter until emergency responders have cleared the building.
After the immediate safety situation is resolved, a licensed plumber or gas fitter needs to locate and repair the source of the leak before gas service is restored. Christian’s licensed plumbers handle gas line repairs and can work with your utility to safely restore service after a leak is addressed.
Major Water Line Leaks
A leak in the main water supply line — the pipe that runs from the street or your well to the home — can cause significant water loss, property damage, and in severe cases, erosion and foundation issues. Signs of a water line leak include an unexplained wet area in the yard between the house and the street, a sudden drop in water pressure throughout the entire home, or a water bill that has spiked dramatically without explanation.
Water line leaks are underground and require locating equipment and excavation to access. This is not DIY territory — and the longer a water line leak goes unaddressed, the more soil erosion and potential structural damage can occur. Shut off the main water supply and call for professional service.
Overflowing Toilet That Cannot Be Stopped
A toilet that overflows and keeps running even after the tank fills is usually a float or flapper issue that can be addressed by reaching into the tank and lifting the float. But a toilet that is overflowing because of a blockage in the drain — where the water level is rising and not draining — is a different situation. If plunging does not resolve it within a few attempts and the water is continuing to rise, stop flushing and call a plumber.
An overflowing toilet that cannot be controlled can quickly cause water damage to flooring and the ceiling of the room below. If the water level is rising toward the rim, shut off the water supply valve at the base of the toilet — it is the small oval valve on the wall behind the toilet — to stop additional water from entering the bowl while you arrange for service.
Frozen Pipes That Have Not Yet Burst
If you turn on a faucet during or after a cold Pennsylvania night and get little to no water, you likely have a frozen pipe. A frozen pipe that has not yet burst is a time-sensitive situation — as ice melts and re-freezes through temperature cycles, the expansion and contraction stress on the pipe increases and the risk of rupture grows.
Frozen pipes in accessible locations — under sinks, in basements — can sometimes be safely thawed with a hair dryer. But pipes frozen inside walls, in crawl spaces, or in other inaccessible areas require a plumber. Attempting to access pipes inside walls without knowing what you are doing can cause more damage than the original freeze. A plumber can locate frozen sections, safely thaw them, and assess whether any damage has occurred.

Sump Pump Failure During a Storm or Heavy Rain
Southeastern Pennsylvania sees significant rainfall and periodic heavy storm events, and a sump pump that fails during an active weather event can result in a flooded basement within hours. If your sump pump stops working during rain — you can hear it is not cycling, or you see water rising in the sump basin — this is an emergency.
If you have a wet-dry vacuum available, using it to manually remove water from the basin while waiting for service can slow the rise. But a failed sump pump during a rain event needs professional attention as quickly as possible. Christian can replace a failed sump pump and assess whether a battery backup system should be installed to protect against future power-outage failures.
Significant Leaks From Supply Lines or Valves
The supply lines that connect water shutoff valves to fixtures — toilets, sinks, dishwashers, washing machines — are under constant water pressure. When these lines fail, they can release a substantial volume of water quickly. Washing machine supply hoses are a particularly common source of significant indoor water damage, as they are often behind appliances and out of sight until a failure occurs.
If a supply line is actively leaking, shut off the individual valve controlling that line if accessible, or shut off the main water supply. Replace braided stainless steel supply lines periodically as a preventive measure — older rubber supply hoses are prone to failure and should be upgraded if they have not been already.
Frequently Asked Questions About Emergency Plumbing
What should I do if I cannot reach my main water shutoff?
If the main shutoff is inaccessible or stuck, the next option is the shutoff at the street — typically requiring a special tool to operate. Your local water authority can also shut off supply at the meter in an emergency. A plumber can repair or replace a main shutoff valve that is stuck or inoperable.
How quickly can Christian respond to a plumbing emergency in Bucks or Montgomery County?
We prioritize emergency calls and aim to respond the same day in most cases. Call us as soon as the emergency is identified — the sooner we arrive, the less damage occurs.
Are emergency plumbing calls more expensive than regular appointments?
Emergency service outside of standard business hours may carry an after-hours rate, which Christian communicates transparently before any work begins. In most emergency situations, the cost of prompt professional service is far less than the cost of the additional damage that results from waiting.
