What to Do in a Drain Emergency

Drain emergencies are stressful — especially when they happen at night or on a weekend. Here's a clear, step-by-step guide on exactly what to do while you wait for a professional drain engineer to arrive.

Step 1: Assess the Situation

Before doing anything else, identify exactly what type of drain emergency you have:

• Sewage backing up into the property — highest priority, call immediately
• All toilets blocked — urgent, call as soon as possible
• External drain flooding — urgent if water is entering the building
• Single sink or bath blocked — less urgent, but still requires attention

Step 2: Stop Making the Problem Worse

The most important thing you can do while waiting for a drain engineer is to stop adding more water to the system:

• Do not flush the toilet if sewage is backing up
• Do not run the dishwasher or washing machine
• Avoid running taps where possible
• Tell everyone in the household what's happening

Adding more water to a backed-up system can cause overflow and increase the risk of sewage entering your home.

Step 3: Protect Your Property

If there is any risk of flooding or sewage overflow:

• Move rugs, furniture, and valuables away from the affected area
• Place towels at the base of toilets or around floor drains if overflow is imminent
• If you have sandbags or flood protection products, deploy them
• Take photos for any potential insurance claim

Step 4: Call a 24/7 Drain Engineer in Derby

Once you've taken these immediate precautions, call a professional drain engineer. Make sure you call someone who is genuinely available 24/7 — not just one who has a 24/7 webpage but requires you to leave a voicemail.

Step 5: What to Tell the Engineer When They Arrive

Help the engineer diagnose the problem faster by telling them:

• When the problem started
• Which fixtures are affected
• Whether you heard gurgling sounds or noticed smells before the blockage
• Whether you have had this problem before
• Whether there are any known drain runs near trees or large shrubs

What NOT to Do in a Drain Emergency

• Don't pour chemical drain cleaners down the drain — they are rarely effective on serious blockages and can damage pipework
• Don't try to dig up or dismantle drain access covers — this is a job for a professional with the right equipment
• Don't ignore sewage smells — these can be a health hazard
• Don't wait and hope it resolves itself — drain emergencies do not get better on their own
