Leave the area. Do not search for the leak or operate gas valves, switches, appliances, or a phone inside.
PHMSA gas-leak guidance ↗Plumbing help: understand the problem and choose the next step.
Start with safety, identify the symptom, and prepare useful details before you contact a professional. This guide is national guidance—it does not claim that a provider serves your city or ZIP code.
Leave an unsafe area before trying to stop the plumbing problem.
If you suspect a natural-gas leak, leave without using switches, flames, or a phone inside and call 911 from a safe location. Do not enter standing water to reach an electrical panel. Avoid contact with sewage. Only shut off the main water valve when you know where it is and can reach it safely.
Do not step into standing water to reach a breaker. A qualified electrician should make the area safe.
CDC electrical-hazard guidance ↗Avoid contact, keep people and pets away, and stop using sinks, showers, and toilets if the sewer line may be damaged.
Red Cross utility guidance ↗Use the main water shutoff only if it is known and safely accessible. Do not cross water or another hazard to reach it.
Red Cross water-line guidance ↗Describe what is happening—not the repair you think you need.
Clear symptoms help a professional decide what information, equipment, and urgency the visit may require.
Visible or suspected leaks, dripping faucets, running toilets, overflowing fixtures, and appliance supply connections.
Slow or blocked drains, several affected fixtures, recurring backups, sewage, or a possible sewer-line problem.
No hot water, a water-heater concern, low or changing pressure, or a main/supply-pipe issue.
Fixture replacement, water treatment, remodel work, or other changes that may need local permits or inspections.
EPA WaterSense identifies common visible leak points at toilets, showers, faucets, water heaters, appliances, hose bibbs, and treatment equipment. Review the EPA technical sheet ↗
Notice what is happening before deciding what the repair might be.
These observations can make the next conversation clearer. They are not a diagnosis or a reason to enter an unsafe area.
Water heater is leaking
Keep away if water could contact electricity. Leave from a safe route if you smell gas. Do not remove panels or disassemble the heater. Only if the area is safe, note whether water appears near a visible connection, at the top, at the bottom, or at a nearby pipe.
Toilet keeps running
First distinguish running water from an overflow or sewage backup. Stop using the fixture if it is overflowing. When the area is dry and safe, a tank dye test can document a possible silent leak, but it does not identify every cause or prescribe a repair.
Drain is slow or backing up
Record whether one fixture or several are affected, whether the problem returns, and whether sewage is present. Avoid contact with sewage and stop using affected fixtures when continued use could worsen a backup.
Water pressure is low or gone
Check only from normal, safely accessible fixtures: is it one outlet or the whole home, and hot water only or both hot and cold? Check for a current utility notice. Do not adjust hidden regulators, pumps, valves, or equipment you cannot identify safely.
Open the complete location-aware guide →Sump pump stopped or water is rising
Standing water near electrical equipment is a stop condition. Keep people and pets out, and do not enter the water to inspect the pump, reach a plug, or operate a breaker. Describe the water level and equipment status only from a dry, safe location.
Only inspect what is visible, dry, and safely accessible.
- Look and listen for drips at exposed faucets and connections.
- Use a toilet-tank dye test to check for a silent leak.
- Clean an accessible faucet aerator or mineral buildup.
- Check whether a showerhead connection is loose.
EPA describes these as basic maintenance checks. Follow product instructions and stop if the work exposes wiring, gas, sewage, hidden piping, or an area you cannot safely isolate.
EPA WaterSense home maintenance ↗Bring in the right professional when the boundary is unclear.
- The leak is hidden, spreading, or cannot be stopped safely.
- Several fixtures are affected or the problem keeps returning.
- There is sewage, suspected contamination, gas, or electrical exposure.
- The work involves a main line, water heater, wall cavity, permit, or code requirement.
Licensing and permit rules differ by jurisdiction. Verify the applicable state, county, and city requirements before hiring.
FTC contractor-hiring guidance ↗A useful description can make the first conversation clearer.
Which fixtures are affected, when it started, whether it is active or intermittent, and what changed.
Say whether water is stopped and whether there is standing water, sewage, a gas odor, or electrical exposure.
Municipal water or well, sewer or septic, relevant appliance, and water-heater type if it relates to the problem.
Photos, visible model information, and prior repair notes can help—but never re-enter an unsafe area to collect them.
Questions to ask before work begins
- Do you serve this exact address and handle this specific problem?
- What license and insurance apply here, and how can I verify them?
- Is there a diagnostic, dispatch, minimum, or after-hours charge?
- What is included and excluded from the written estimate?
- Who obtains permits and schedules inspections when required?
- How are additional work and price changes authorized?
- Are cleanup, restoration, subcontractors, and warranty terms documented?
The FTC recommends checking required licenses and insurance and comparing written estimates that describe the work, materials, timing, and price. Read the FTC guidance ↗
There is no responsible single national price for “plumbing repair.”
The symptom, access, urgency, materials, labor model, permits, cleanup, and location all change the scope. This guide does not publish a numeric range without reviewed observations that match the actual job and market.
An advertised price, a phone estimate, a written estimate, an approved change order, and a final invoice are different things. Ask which one you are being given.
A ZIP code helps check rules and availability; it does not make this a local page.
Provider coverage, schedules, licenses, permits, utility responsibility, advisories, and prices require current local evidence. Call Home Help does not infer full-city coverage from one ZIP code.
If water pressure changes or tap water changes in color, taste, or smell, CDC advises contacting the water utility or health department; follow any local drinking-water advisory. CDC drinking-water guidance ↗

Read answer →Plumbing questions people ask first
Is this a plumbing emergency?
Leave and call emergency services from a safe place for a suspected gas leak. Keep away from water that may contact electricity and avoid sewage. An uncontrolled leak also needs prompt action, but only use a shutoff you can reach safely.
Why is my drain backing up?
A page cannot determine the cause from that symptom alone. Note whether one or several fixtures are affected, whether the backup returns, and whether sewage is present. Stop using affected fixtures and avoid contact if sewage or a possible broader line problem is involved. See the drain pathway.
What should I do if a pipe bursts?
Keep away from water near electricity and use a known main shutoff only when it is safely accessible. Protect people from the area, avoid disturbing hidden piping, and describe where water is appearing from a dry location. Review the safety boundaries.
When should I call a plumber instead of checking it myself?
Stop at visible, dry, accessible observations. Seek qualified help for a hidden or spreading leak, recurring or multi-fixture backup, sewage, a water heater, main line, wall cavity, permit question, or any gas or electrical hazard. Review the stop conditions.
Why is my water pressure low throughout the house?
Whole-home pressure can involve the home system or a utility condition, and this page cannot diagnose which. Compare hot and cold at ordinary fixtures, check current utility notices, and contact the utility or a qualified professional rather than adjusting unfamiliar equipment. See the pressure pathway.
What should I do before a plumber arrives?
Protect people from the area, stop using affected fixtures, shut off water only if safe, and record the symptoms and timing. Do not disturb gas, wiring, sewage, or hidden piping.
Can I check the problem myself?
Limit checks to visible, dry, accessible fixtures. A toilet dye test, an exposed drip check, or cleaning an aerator may be reasonable; stop whenever safety or the repair scope is uncertain.
How do I verify a plumbing professional?
Check the license required by your state or county, request proof of insurance, compare written estimates, and read the written scope and payment terms before work starts.
Why is there no national price range?
“Plumbing repair” does not identify one comparable job. A useful range needs reviewed evidence for a defined service, market, date, and set of inclusions; this national guide does not have that comparable price evidence.
Could the water utility be the right first call?
Possibly. Changes in water quality or pressure and suspected municipal sewer problems can involve a utility or health department. Responsibility and contact procedures must be checked locally.
