Emergency drain unblocking in Salisbury — a real customer story

Emergency drainage issues can bring a home to a complete standstill. When water backs up into sinks, toilets or outdoor drains, quick action is essential to prevent flooding, damage and health hazards.
This real case study from Salisbury Drains24 shows how our team handled a late-evening emergency callout in Harnham — restoring full flow within an hour using high-pressure jetting and CCTV diagnostics.


The emergency call — water overflowing from an outdoor drain

At 8:45pm, a homeowner in Harnham, Salisbury noticed water overflowing from an outdoor gully near the kitchen. The smell was strong, and multiple household drains had become slow during the day.

They contacted Salisbury Drains24 for urgent help.

When our engineer arrived, they found:

  • Standing wastewater around the gully
  • Gurgling noises in the kitchen sink
  • Slow-flowing bathroom drains
  • Surface water pooling near the back door

These were clear signs of a mainline blockage.


Step 1 — Locating and assessing the blockage

The engineer lifted the nearest inspection chamber and found wastewater sitting almost at the top — meaning the blockage was further downstream.

Because the property had a mix of clay and PVC pipework (common in older Salisbury areas), the engineer used a manual rod to test for soft blockages. The rods hit solid resistance, indicating something more substantial.

This required high-pressure jetting.


Step 2 — High-pressure jetting to clear the obstruction

Using a WJA-approved jetting unit, water was introduced into the pipe at controlled pressure. Within minutes, the jetting hose broke through the obstruction and released a surge of water.

What emerged?

  • Grease buildup
  • Tissue and sanitary waste
  • Silt
  • Fine tree roots

This mixture had compacted into a solid blockage inside the pipe, causing the household system to back up.


Step 3 — CCTV inspection to check for deeper problems

Once the blockage was cleared, the engineer carried out a CCTV drain survey to inspect the pipe condition and identify the reason for the blockage.

The camera revealed:

  • Hairline cracks in the clay pipe
  • A small joint displacement
  • Fine roots entering through the crack
  • Minor silt accumulation caused by slow flow

These issues were not serious enough to require immediate repair, but preventative action was advised.


Step 4 — Recommendations for long-term protection

The homeowner received a detailed report showing:

  • Pipe condition
  • Root intrusion location
  • Recommended maintenance schedule
  • Suggested future repairs (non-urgent)

We advised:

  • Annual CCTV check
  • Jetting every 12–18 months
  • Root cutting if intrusion worsens
  • Considering relining in future if cracks widen

The customer was relieved that no excavation was needed, and the system was fully restored the same night.


Why emergency unblocking is common in Salisbury

Salisbury’s combination of older clay drains, tree-heavy areas (Laverstock, Harnham, Bemerton Heath) and seasonal rainfall makes emergency blockages quite common.

Typical causes include:

  • Grease buildup in kitchen drains
  • Root intrusion
  • Silt and mud
  • Misaligned pipe joints
  • Flushed wipes
  • Heavy rain overwhelming gullies

Regular maintenance helps to reduce emergency callouts significantly.

Emergency Drain Unblocking FAQs

What causes emergency drain blockages?

Blockages in Salisbury are often caused by grease buildup, wipes, silt, leaves, or root intrusion. Heavy rainfall also pushes debris into gullies, leading to sudden overflows and backups.

How fast can you respond to emergency callouts?

Salisbury Drains24 provides 24/7 rapid response. Most emergency arrivals occur within an hour, depending on traffic and location.

Do I always need jetting for a blockage?

Not always. Some blockages clear with rodding, but stubborn or recurring issues usually require high-pressure jetting for a complete and safe clearance.

What if my drain blocks again after clearing?

Recurring blockages often indicate cracks, root intrusion, or silt buildup. A CCTV survey identifies deeper issues and helps prevent repeat emergencies.

Can you fix damaged pipes during an emergency visit?

Temporary fixes are possible, but long-term repairs like relining or patching are scheduled after camera inspection. Emergency visits focus on restoring flow safely.
