Pressure washers wear out. Seals go, valves stick, hoses split. We keep the common parts in stock so you're not waiting around.

If you know the part number, search for it. If you don't, ring us with the machine model and we'll figure it out. Been doing this long enough to know most machines inside out.

What Goes First

Pump seals and valves - usually the first thing to need replacing. You'll notice the pressure dropping or water leaking from the pump head.

High-pressure hoses - check them regularly. Bulges, cracks, worn spots mean it's time for a new one. A burst at 200 bar is dangerous.

Nozzles wear out slowly. The hole gets bigger, pressure drops, cleaning takes longer. Easy to miss but worth checking.

Frequently asked questions

What power washer parts are most commonly replaced?
Pump seals and valves are typically the first components to require replacement, often indicated by pressure drops or leaks from the pump head. High-pressure hoses and nozzles also wear over time and may need periodic replacement.
How do I identify the right pump for my pressure washer?
You will need the machine model number or the existing pump model. Interpump models like the W98 and W154 are common replacements, but matching the correct pressure rating and flow rate to your machine is essential.
What is the difference between bottom entry and rear entry pressure gauges?
The difference is the orientation of the threaded connection. Bottom entry gauges connect from underneath, while rear entry gauges connect from the back, allowing you to mount the gauge in the position that suits your machine layout.
When should I replace a pressure washer hose?
Replace a hose if you see bulges, cracks, or worn spots. A burst at operating pressure is dangerous and can cause injury or equipment damage.
What are turbo nozzles and which one do I need?
Turbo nozzles rotate a concentrated jet to cover more area while maintaining high impact. Choose based on your machine's maximum pressure: standard turbo nozzles suit up to 200 bar, medium duty up to 250 bar, and heavy duty up to 310 bar.
Can I fit a Honda GX200 or GX390 engine to my pressure washer?
Honda GX engines are common replacements for petrol pressure washers. The GX200 suits smaller machines, while the GX390 fits larger units. You will need to match the shaft type and mounting configuration to your pump and frame.
How do I know when a pressure washer nozzle is worn out?
Nozzles wear gradually as the orifice enlarges, reducing pressure and cleaning efficiency. If jobs are taking noticeably longer or the spray pattern looks weak, the nozzle has likely worn beyond usable tolerances.
