What to Do in a Plumbing Emergency Before the Plumber Arrives (St. Charles County Guide)

Plumbing Tips & Guides
April 3, 2026

Plumbing emergencies can happen without warning—and when they do, every second matters. A burst pipe, sewer backup, or major leak can quickly cause serious damage to your home if not handled properly.

If you’re facing a plumbing emergency in St. Charles County, knowing what to do before the plumber arrives can save you time, money, and stress.

This guide walks you through the exact steps to take—and when it’s time to call a professional.

What Is Considered a Plumbing Emergency?

Not every plumbing issue needs immediate attention, but some situations require urgent action.

You may be dealing with a plumbing emergency if you have:

  • A burst or rapidly leaking pipe
  • Sewer backup or foul sewage smell
  • No water in your home
  • No hot water (especially during winter)
  • Overflowing toilet that won’t stop
  • Water pooling on floors or walls

If water is actively damaging your home or creating a health risk, it’s an emergency.

Step 1: Shut Off the Water Supply Immediately

The first thing you should do is stop the water flow.

  • Locate your main water shut-off valve
  • Turn it clockwise to shut off water
  • For smaller issues, shut off the valve near the fixture

This step alone can prevent thousands of dollars in damage.

Step 2: Turn Off Your Water Heater

If your plumbing system is compromised, your water heater could be at risk.

  • Turn off power at the breaker (electric units)
  • Turn off the gas valve (gas units)

This helps prevent overheating, pressure buildup, or internal damage.

Step 3: Shut Off Electricity (If Needed)

If water is near electrical outlets, appliances, or your breaker panel:

  • Turn off electricity in that area
  • Avoid standing water
  • Do not touch wet electrical components

Safety comes first—never take risks with electricity.

Step 4: Contain the Water and Minimize Damage

While waiting for help:

  • Use towels or mops to soak up water
  • Place buckets under leaks
  • Move furniture, rugs, and valuables away from affected areas

Quick action here can significantly reduce repair costs.

Step 5: Avoid DIY Fixes That Can Make It Worse

In emergencies, trying to fix things yourself can sometimes cause more harm.

Avoid:

  • Using chemical drain cleaners during backups
  • Overtightening pipe connections
  • Taking apart plumbing without proper tools

Temporary fixes often fail—and can make repairs more expensive.

When Should You Call a Plumber Immediately?

Some situations should never be delayed.

Call a professional right away if you notice:

  • Continuous leaking or flooding
  • Sewage backing up into your home
  • No running water
  • Sudden drop in water pressure across the house
  • Water heater failure or leaking tank

If you’re dealing with any of these, it’s time to request emergency plumbing service immediately.

I needed a plumber ASAP. I called five different companies and they all said they didn't have appointments available until next week. I called Arch Plumbing and they said they could be at my home within 2 hours. I asked how much the service fee and diagnostic fee would be and was told that there is no charge for coming to my home. Tony was here in less than 2 hours. He quickly found the problem and he gave me a quote for repair and the quote was very reasonable. Tony said he would finish in about an hour. He finished in less than an hour. The problem was fixed and I could not have asked for more. I highly recommend Arch Plumbing and Tony in particular, although I'm sure that all of the other Plumbers are excellent as well.
