How to Use High Pressure Water Jet Cleaning Equipment for Sewer and Drain Pipe Unblocking

1. Why Sewer and Drain Cleaning Is Necessary？

Blocked or slow-flowing drainage systems are a common challenge in cities, residential communities, and industrial facilities. Over time, pipelines accumulate grease, sludge, sand, roots, and other deposits, causing drain blockages, foul odors, and overflow problems.
Traditional manual cleaning methods are often time-consuming, inefficient, and may even damage the pipeline structure. For municipal maintenance teams, property management companies, and industrial service providers, an effective, safe, and long-lasting pipeline cleaning solution is essential to maintain smooth operation and environmental hygiene.

2. Common Sewer and Drain Cleaning Methods — Comparison and Advantages

There are several ways to clean and unblock drainage pipelines, each with its own characteristics. Below are the most common options:

(1) Mechanical Rodding

This method uses a rotating metal rod or spiral tool to physically break up the blockage.

• ✅ Advantage: Low cost and simple tools.

• ❌ Disadvantage: Ineffective for long-distance pipelines; limited to partial blockages; may scratch or damage pipes.

(2) Chemical Cleaning

Chemicals are poured into drains to dissolve grease and sludge.

• ✅ Advantage: Quick surface effect, suitable for household drains.

• ❌ Disadvantage: Harmful to the environment, unsafe for operators, and may corrode the pipeline.

(3) High Pressure Water Jet Cleaning — The Most Efficient and Eco-friendly Solution

The High Pressure Water Jet Drain Cleaning Machine uses high pressure water flow (200–250 bar) to generate a strong water jet stream, which removes deposits, roots, and sediments from the inner pipe wall through impact and shear force.

• ✅ Advantages:

  • Efficient & Time-Saving: Cleans large sections quickly without dismantling pipes.

  • Safe for Pipelines: No mechanical friction or chemical corrosion.

  • Environmentally Friendly: Only clean water is used, with zero pollution.

  • Versatile Application: Suitable for municipal sewers, residential drains, industrial wastewater lines, and school drainage systems.

  • Long-Term Effect: Restores pipe flow and prevents re-blockage.

Because of these advantages, high pressure sewer jetting machines have become the mainstream choice for professional pipeline maintenance companies worldwide.

3. Selecting the Right High Pressure Water Jet Cleaning Equipment

When choosing a high pressure drain cleaning system, the key parameters are pressure, flow rate, and drive type.

Recommended Selection Range:

• Pressure Range: 200 – 250 bar

• Flow Rate: 50 – 170 L/min

• Drive Options: Electric motor drive, diesel engine drive, or gasoline engine drive

The pressure and flow should be selected according to the pipeline diameter and blockage level.

• For small residential or property pipelines (50–150mm) → choose around 200bar / 50LPM

• For municipal or factory drainage systems (150–400mm) → choose 220–250bar / 100–170LPM

Drive type can also be customized:

• Electric drive: Quiet, low maintenance, ideal for indoor or residential areas.

• Diesel drive: Strong power, suitable for outdoor or municipal operations.

• Gasoline drive: Compact and portable, ideal for mobile service teams.
