Emergencies: what to do in the first ten minutes
These answers are general. They tell you what to do while you wait, not what your pipes need. A plumber who sees the problem gives the real answer.
What should I do right away during a plumbing emergency in Cedar City?
Find the main water shutoff and close it, stop using the fixture that is failing, and keep people away from any standing water near outlets. If you smell gas, leave the building and call the gas utility or 911 from outside. Then call and describe what you see.
Step-by-step help for the worst case is on the burst pipe emergency page.
A pipe burst. What do I do first and what can wait?
Close the main water valve inside the house first, then open a low faucet to drain the lines and switch off the water heater. Photograph the damage and move belongings off wet floors. The repair, drying and insurance calls can wait until the water is off.
What should I do if I smell gas?
Leave the building at once with everyone, including pets, and do not flip switches, light a flame or start appliances on the way out. From outside, call the gas utility’s emergency line or 911. Call a plumber only after the utility says the home is clear.
What a plumber can and cannot do about gas is on the gas smell and leak steps page.
How do I keep pipes from freezing during a Cedar City cold snap?
Insulate pipes in garages, crawl spaces and exterior walls, disconnect hoses, and open the cabinet doors under sinks on exterior walls. In a hard freeze, keep the heat on and let a faucet at the far end of the house drip. Cedar City’s January lows average about 18°F, so know where your main valve is before the first freeze.
The full steps for a frozen or split line are on the frozen and split pipes page.
Leaks, high bills and who handles what
My water bill jumped and I cannot see a leak. How do I check the meter?
Turn off every fixture, read the meter, wait thirty minutes without using water, then read it again. A changed number, or a low-flow indicator that keeps turning, means water is leaking after the meter. The test does not show where, so describe the result when you call.
The full meter test, with what each result means, is on the leak detection page.
Does Cedar City look for leaks on my side of the meter?
Cedar City’s 2024 Water Conservation Plan says the city does not run an active leak detection program, and it reads customer meters monthly. A leak after your meter is yours to find, so start with the meter test. Confirm anything about your own account with the Cedar City water department.
Where the leak is determines who fixes it. See tracing a house or yard leak.
What are the signs of a hidden slab leak?
Warm spots on the floor, the sound of running water with every fixture off, a meter that keeps turning, damp carpet or a stained baseboard, and a higher water bill. Several signs together are more telling than one, and a plumber still has to locate the leak.
More is on the slab leak signs page.
Why does my toilet periodically run on its own without being flushed?
This phantom flushing is almost always caused by a deteriorating rubber flapper or a misaligned fill valve inside the toilet tank, allowing water to slowly leak into the bowl until the tank refills. It wastes water between flushes and is usually a small repair. Dropping a little food coloring in the tank shows whether the flapper is leaking.
More is on the toilet tank parts and fixes page.
Can I test or run outdoor lines during Cedar City’s watering restriction hours?
Cedar City’s 2024 water plan lists a standing limit on outdoor watering from 8 AM to 6 PM between April 1 and October 31, under ordinance 37-7-1. The city can also issue temporary limits, as it did in August 2026 after a well pump failure. Hours can change, so confirm the current rule with the city before running a sprinkler test, and ask the plumber whether the check needs water running outdoors.
Water you cannot stop, or a smell of gas?
Close the main valve or leave the building, then call.
Water heaters and hard water
My water heater is leaking. Is it the tank or a fitting, and can it be repaired?
Check where the water starts. A leak at the inlet, outlet, relief valve or drain valve is usually a repair. Water coming from the tank body or the base usually means the tank has corroded through, and the answer is replacement. Shut off the cold water valve above the heater and call with what you see.
Repair choices are covered on the water heater repair page.
Is Cedar City water hard, and what does it do to my water heater?
A USGS estimate for Iron County puts hardness at about 13.1 grains per gallon, which is very hard. It is a county estimate, not a tap reading. Hard water leaves scale in tanks and on elements, so ask a plumber how to manage sediment and whether treatment makes sense.
Testing and treatment questions are on the water softener page.
How long do standard water heaters last in Cedar City, UT?
Traditional tank water heaters in Cedar City generally last 8 to 12 years, while tankless units can operate for 18 to 25 years with annual descaling maintenance. Hard water speeds up scale, so a tank that is flushed and checked on a schedule tends to reach the top of that range. A leak from the tank body is the usual sign that the end has come.
Choices when the time comes are on the water heater replacement page.
Should I replace a tank heater with tankless or a heat pump model?
It depends on household size, space and fuel. A tank is the simplest swap. Tankless suits larger households and tight spaces but needs the right gas line and venting. A heat pump model saves energy on electric but needs open space and airflow. Ask the plumber to compare the options for your house.
The tradeoffs are laid out in replacing a water heater and, for tankless, tankless water heaters.
Drains, sewer lines and digging
My sewer is backing up. What should I document before the plumber arrives?
Note which drains are affected and where the backup shows first, when it started and whether anything triggered it. Take photos or video of the water and note any recent digging or roots near the line. Stop using water in the meantime.
See sewer backup and line repair for what a camera inspection should record.
Why does the same drain keep clogging, and is snaking enough?
A snake clears the clog in front of it but does not explain why it formed. A drain that clogs again within months usually has a cause the cable cannot show: grease coating the pipe, roots, scale, or a sag or break in the line. Ask for a camera inspection and a record of what it finds before paying for another cleaning.
Repeat clogs are covered on the drain cleaning page.
How do I know if tree roots are in my sewer line?
Slow drains, gurgling and repeat backups that follow a cleaning are common signs, but only a camera can confirm roots. Ask the plumber to record the camera pass, note where the roots enter and tell you whether the pipe is damaged there.
When is trenchless pipe lining (CIPP) recommended over traditional sewer excavation?
Trenchless lining is ideal when the underground sewer line has cracks, root intrusions, or corrosion but has not completely collapsed. It installs an epoxy sleeve inside the existing pipe through a small access point, so most of the yard stays in place. If the pipe has collapsed or sags so that it holds water, digging is still needed. A camera inspection tells which case you have.
See what lining involves for how the process works and what to ask.
How often should residential drains be professionally cleaned or hydro jetter cleared?
Standard preventative drain cleaning is recommended every 18 to 24 months for single-family homes. For properties with mature tree roots or frequent kitchen grease, the interval is shorter, and a camera pass shows how fast buildup returns. A drain that clogs again within months needs a diagnosis, not a fixed schedule.
Scouring a main line is covered on the hydro jetting page.
Do I need to call 811 before a sewer or water line repair that involves digging?
Digging near buried utilities needs a locate. Blue Stakes of Utah takes locate requests online at any hour. Ask your plumber who requests it and how the marks are handled.
Hiring, calling and costs
How can I check that a plumber is licensed in Utah?
Ask for the name the license is held under, then search it in the Verify a License tool run by the Utah Division of Professional Licensing. Confirm that the license is active and that the name matches the person or company you are dealing with.
The state tool is <a href="https://secure.utah.gov/llv/search/index.html" rel="noopener">Utah DOPL: Verify a License</a>.
What happens when I call, and what will the plumber quote before starting?
You talk to a plumber about what you see, and the plumber explains the likely causes and the options. The price for the work is quoted before it starts. Hidden problems change the price, so nobody can give a fixed figure by phone, and this site does not promise an arrival time.
How are plumbing costs decided, and why can nobody quote a fixed price by phone?
Price follows what the job turns out to be: the cause, access to the pipe, the materials and whether a permit or a second visit is needed. Ranges can show what is typical, but only a plumber who has seen the problem can quote it. Ask for a written quote with each part on its own line.
See typical price ranges for wide planning figures.
