High-pressure washers for pipe and sewer cleaning – HD-2500, HD-3000, and HD-4000 from the manufacturer

Drexl High-Pressure Washers in Detail

The HD-2500 is our compact entry-level model in high-pressure flushing technology: With 130 bar, 12 l/min, and a 35-meter high-pressure hose, it is suitable for workshops, plumbing applications, and house connections. It can be operated on a 230-volt power supply, making it usable even in enclosed spaces. The HD-3000 is the mobile high-performance model: A 13-horsepower Honda 4-stroke gasoline engine powers the washer with 220 bar and 20 l/min. With a 60-meter hose length and no need for a power supply, it is ideal for construction sites, outdoor use, and particularly stubborn dirt. The HD-4000 combines a powerful 8-kW electric motor with 150 bar and a flow rate of 26.7 l/min. This high water volume really comes into its own over long cleaning distances and with large-volume dirt, where consistent hydraulic performance matters more than peak pressure.

Nozzles and accessories – the right tool for every type of dirt

A high-pressure washer only achieves its full performance with the right nozzle: The nozzle directs the water jet, accelerates it, and adapts it to the specific type of dirt. We carry a comprehensive range of pipe cleaning nozzles, ensuring you have the right tool on hand for every application. Classic standard nozzles are used for normal flushing tasks, rotor nozzles and root cutters remove root ingrowth with a rotating jet, and pipe-bottom cleaners are specifically designed for cleaning the pipe bottom in larger sewers. For special profiles and specific applications, we offer egg-shaped nozzles, Tri-Jet nozzles, Quattro 3-Angle nozzles, as well as radial nozzles and the Pipe Wolf. In addition, we supply high-pressure flushing hoses in various lengths, swivel joints, and deflection rollers for the bottom of manholes, so you receive the complete, ready-to-use system from a single source.

Typical applications of high-pressure flushing

High-pressure flushing is the hydromechanical cleaning method of choice when contaminants need to be removed using water pressure rather than mechanical tools. Typical applications include grease, lime, and sludge deposits, sand and gravel deposits, root ingrowth, and residual contamination following mechanical work. In daily professional use, Drexl high-pressure flushing systems clean underground pipes, house connections, downspouts, industrial pipelines, and municipal sewers. They are used before newly laid pipes are put into service, as well as prior to TV inspections or as part of routine maintenance. Our typical users include sewer cleaning and rehabilitation companies, municipal maintenance depots, property management services, plumbing companies, and industrial facilities with their own plant maintenance departments.

High-pressure flushing or mechanical auger – when to use which

High-pressure flushing and augers are not competing methods, but rather complement each other in practice. A mechanical auger is the right choice for hard blockages, solid deposits, and heavily branched root systems that must be physically broken up. A high-pressure flusher excels at removing grease, lime, sludge, and sand, as well as thoroughly flushing longer sections, and is also ideal for the final cleaning after an auger application. Many professional companies therefore use both methods in parallel. If you do not yet have a mechanical solution in your product range, you can find our complete selection of pipe cleaning machines with augers in the corresponding category.

Consulting, Service, Leasing, and Financing

We don’t just sell equipment; we provide fair and expert advice on your selection, free of charge via our hotline, and have been serving our customers since 1986. We offer free shipping within Germany. For commercial customers, financing via leasing is also available upon request. As professional equipment, high-pressure washers are typically classified as fixed assets and depreciated over their normal useful life. Please consult your tax advisor regarding the specific classification.

Frequently Asked Questions About High-Pressure Washers

Which high-pressure washer is suitable for which application?

For workshops and smaller plumbing applications on a 230-V power supply, the HD-2500 with 130 bar is the right choice. For mobile applications and particularly stubborn dirt, the HD-3000 with 220 bar and a Honda gasoline engine offers the necessary power and independence from the power grid. If you’re flushing over long distances with high water flow, the HD-4000 with 26.7 l/min is the right choice.

What do bar and liters per minute mean for a high-pressure washer?

Bar indicates the working pressure the unit generates at the nozzle outlet. Liters per minute indicate the flow rate, i.e., how much water is delivered per unit of time. High pressure is good for mechanically loosening solid deposits, while high flow is good for flushing away large amounts of dirt over long distances. In practice, the combination of both is crucial for successful cleaning.

Which nozzle for which type of dirt?

Standard nozzles are suitable for normal flushing tasks and uniform cleaning. Rotor nozzles and root cutters are designed for root ingrowth and stubborn deposits, as the rotating jet delivers more energy to the pipe wall. Pipe-bottom cleaners clear the pipe bottom in larger channels, and egg-shaped nozzles are specifically designed for channels with an egg-shaped profile. For stubborn special cases, we also offer Tri-Jet, Quattro3Kant, radial nozzles, and the Rohr-Wolf.

How far does a high-pressure flusher reach into the pipe?

The effective reach depends on the hose length, the pipe diameter, and, above all, the nozzle. Our Drexl high-pressure flushing machines are supplied with hose lengths ranging from 35 to 60 meters, depending on the model. With the right thrust nozzles, these lengths can be utilized almost to their full extent because the hose pulls itself into the pipe due to the nozzle recoil.

High-pressure flushing machine or pipe cleaning machine with a spiral?

Coils and high pressure complement each other. For solid, mechanically wedged blockages and root systems, the mechanical coil reaches the target faster. For widespread, softer debris such as grease, lime, sludge, or sand, high-pressure flushing is the better tool. Many professionals use both in parallel, often even on the same job.

Can I write off a high-pressure washer as a business asset for tax purposes?

In commercial use, high-pressure washers are typically depreciable as movable assets under fixed assets. The specific depreciation classification, useful life, and treatment in individual cases depend on your company’s situation. Please consult your tax advisor. Upon request, we also offer leasing to commercial customers as an alternative to direct purchase.
