🚰 Blocked Drains: What Causes Them and How High Pressure Water Jetting (HPWJ) Clears Them
Blocked drains are one of the most common plumbing problems for homeowners and businesses. What starts as a slow-draining sink or bad smell can quickly turn into an overflowing manhole or sewage backup if left untreated.
At Clean A Drain Ltd, we use powerful High Pressure Water Jetting (HPWJ) equipment to remove stubborn blockages and restore your drains to full working order. 💧
🚨 Common Causes of Blocked Drains
🛢️ Fat, Oil and Grease (FOG)
Cooking fats and oils harden inside pipes, trapping food waste and creating tough blockages.
🧻 Wet Wipes and Hygiene Products
Even “flushable” wipes can build up and cause major obstructions.
🌳 Tree Roots
Roots can enter drains through tiny cracks, restricting flow and damaging pipework.
🛁 Hair and Soap Scum
A common cause of slow-draining baths and showers.
🧸 Foreign Objects
Toys, sanitary products, and other items can cause sudden blockages.
🏚️ Collapsed or Damaged Pipes
Structural issues often lead to recurring drainage problems.
⚠️ Warning Signs of a Blocked Drain
Look out for these signs:
🚿 Water draining slowly
🚽 Toilets not flushing properly
🔊 Gurgling sounds from sinks or toilets
👃 Unpleasant smells
💦 Water backing up
🌊 Overflowing external drains or manholes
💥 What Is High Pressure Water Jetting (HPWJ)?
High Pressure Water Jetting uses specialist equipment to pump water through your drains at extremely high pressure.
A specially designed nozzle blasts water forwards and backwards to:
✅ Break up blockages
✅ Remove grease and sludge
✅ Cut through tree roots
✅ Flush debris away
✅ Clean the full pipe wall
⚙️ How HPWJ Works
1️⃣ Inspection
We assess the blockage and choose the right jetting nozzle.
2️⃣ Setup
The hose is inserted into the drain or manhole.
3️⃣ Jetting
Powerful water jets break up and remove the obstruction.
4️⃣ Full Pipe Cleaning
The pipe walls are thoroughly cleaned.
5️⃣ Final Checks
We test the flow and can carry out a CCTV survey if required.
🆚 Why HPWJ Is Better Than Drain Rodding
Traditional rods may only poke a hole through the blockage.
HPWJ:
🧼 Cleans the entire pipe
💪 Removes stubborn build-up
🔄 Helps prevent repeat blockages
⚡ Fast and highly effective
