Plumbing problems love bad timing. A pipe lets go on a Saturday night, a drain backs up on Sunday morning, or the water heater quits during a cold snap. When that happens, you do not want a list of maybes. You want an emergency plumber in Katy who picks up the phone, and you want to know what to do until they arrive.
If you live in Katy or nearby communities like Fulshear, Richmond, Sugar Land, or Brookshire, this guide covers the seven plumbing emergencies we get called about most after hours. For each one, you will see what to do right away to limit the damage, and how to tell a real emergency from a problem that can wait until morning.
Quick answer: Call an emergency plumber in Katy right away if water is flooding or spraying, sewage is backing up, a toilet will not stop overflowing, your water heater is leaking, you suddenly have no water, or water is coming through a ceiling. First, shut off the main water valve and stay clear of electrical hazards. If you ever smell gas, leave the house and call your gas utility or 911 before anything else.
What Counts as a Plumbing Emergency?
Not every drip needs a midnight call. But if water is spreading, sewage is involved, or the problem is getting worse by the hour, waiting can turn a repair into a restoration project.
Treat it as an emergency if:
- Water is flowing, spraying, or pooling and will not stop
- Sewage or dirty water is coming up from a drain
- Water is near outlets, appliances, or your electrical panel
- A ceiling is sagging, bulging, or dripping heavily
- You have no water at all, or the pressure suddenly drops
- You smell gas near a water heater or gas appliance
A slow drip under a sink, one slow drain, or a running toilet can usually wait for a regular appointment. Shut off the water to that fixture and call during business hours.
1. Burst or Leaking Pipes
What you will notice: Water spraying from a wall, ceiling, or under the house, a sudden drop in pressure, wet drywall, or the sound of running water when everything is off.
What to do first:
- Shut off the main water valve. It is usually near the water meter, along an exterior wall, or in the garage.
- Open a few faucets to drain the lines and release pressure.
- Turn off power to the wet area at your breaker box, but only if you can reach it without standing in water.
- Use towels and buckets to contain the water, and move belongings out of the way.
What a plumber does: Finds the break, repairs or replaces the damaged section, and checks the pipes around it. When the leak is hidden inside a wall or under a slab, our leak detection and repair service finds the source without tearing apart more of your home than necessary.
2. Sewage Backing Up Into Your Home
What you will notice: Dirty water rising in a tub, shower, or floor drain, gurgling from several drains at once, or a strong sewer smell indoors.
What to do first:
- Stop using water. That means toilets, sinks, the washer, and the dishwasher. Everything you run goes into the same blocked line.
- Keep kids and pets away, since sewage carries bacteria.
- Wear gloves and boots if you have to go into the area.
- Skip the chemical drain cleaners on a main line backup.
What a plumber does: Finds the blockage, which is often tree roots, a collapsed section, or built-up debris, and clears or repairs it. When several fixtures back up at once, the problem is usually in the main line, and that is exactly what our sewer line services are for.
3. An Overflowing Toilet or Stubborn Clog
What you will notice: A toilet that keeps rising after you flush, water coming over the bowl, or a drain that will not move no matter what you try.
What to do first:
- Turn the toilet’s shut-off valve (behind the base) clockwise to stop more water entering the bowl.
- Lay down towels.
- Try a flange plunger with firm, steady strokes.
- If it does not clear in a few tries, stop. Forcing it can make it worse.
What a plumber does: Clears the clog with professional equipment and checks whether it is a simple blockage or a sign of a bigger problem. If the same drain keeps clogging, our drain cleaning removes the buildup instead of poking a temporary hole through it.
4. A Leaking or Failed Water Heater
What you will notice: Water pooling around the tank, rusty hot water, no hot water, or loud popping and rumbling. A burst tank can release a lot of water quickly.
What to do first:
- Turn off the power at the breaker (electric) or set the gas control to off or pilot (gas).
- Close the cold water supply valve on top of the heater.
- Use towels and a bucket to contain the water, and keep clear of hot water on the floor.
What a plumber does: Figures out whether it is a simple fix, like a valve or connection, or whether the tank itself has failed. A leaking tank cannot be patched. Our water heater repair and replacement team can get your hot water back and walk you through your options.
5. No Water or Sudden Low Pressure
What you will notice: Taps that run dry, a trickle where there used to be strong flow, or pressure that drops all at once.
What to do first:
- Check whether your neighbors are affected too. If it is a city supply issue, a plumber cannot fix it.
- Make sure your main shut-off valve is fully open.
- Look around the house and yard for wet spots, which can point to a broken line.
- Check your water meter. If it keeps moving with everything off, you likely have a leak.
What a plumber does: Pinpoints the cause, whether that is a broken service line, a failed valve, a pressure regulator problem, or a hidden leak, and makes the repair.
6. Water Coming Through the Ceiling or Walls
What you will notice: Brown or yellow stains spreading on the ceiling, bubbling paint, a sagging or dripping ceiling, or water running down a wall.
What to do first:
- Shut off the main water valve if the source could be plumbing.
- Move furniture and valuables out of the way.
- If the ceiling is bulging or dripping heavily, clear everything from underneath it and keep people away from that spot.
- Stay clear of light fixtures and electrical items near the water.
A sagging ceiling is not a DIY job. Let a professional deal with it.
What a plumber does: Traces the leak to its source, which could be a supply line, a drain line, or an upstairs fixture, and repairs it. Katy gets heavy rain too, so a plumber can also help you tell whether the water is coming from your plumbing or your roof.
7. A Gas Smell Near Your Plumbing or Appliances
What you will notice: A rotten-egg smell near the water heater, stove, or gas lines.
What to do first, and this is the most important one: Do not flip switches, use your phone inside, or light anything. Get everyone out of the house, then call your gas utility or 911 from a safe distance. A gas leak is an emergency for the gas company and fire department first.
What a plumber does: Once the utility has made the area safe, a licensed plumber can inspect, repair, or replace damaged gas lines and connections.
What to Tell the Plumber When You Call
The more detail you give, the better prepared the plumber will be when they arrive:
- Your address and a good callback number
- What you see, hear, or smell
- Where the problem is (kitchen, bathroom, garage, yard)
- Whether you have shut off the main water or power
- How long it has been going on
If you can send photos, even better.
What Not to Do During a Plumbing Emergency
- Do not ignore it and hope it stops by morning
- Do not keep running water to see if it clears
- Do not use chemical drain cleaners on a backup
- Do not touch electrical items while standing in water
- Do not try major repairs yourself at night
Towels, buckets, and repair tape buy you time, but they are not repairs. Always follow up with a licensed plumber.
