How do you safeguard your pressure washer?

As winter approaches, the nights are becoming longer, and temperatures are dropping. It is essential to consider how to safeguard your pressure washer from freezing conditions.

Pressure washers contain water throughout their systems, and when this water freezes, it expands, potentially causing damage to various components such as pumps, filters and hoses, which are not covered under warranty and may result in expensive repairs.

To prevent this, storing the unit in a warm, frost-free environment is advisable. If possible, run an anti-freeze solution (Mono Ethylene Glycol) through the machine. (Do not use Ti-Ethylene Glycol)

Additionally, consider wrapping it in blankets or insulated covers.

If these options are not feasible, ensure all water is drained from hoses, lances, and pump components. Leave the easy bleed valve open if available, unscrew the unloader valve, remove the filter bowl, and take out the bottom bung on the head to drain the water completely.

• Before winter storage: Drain the petrol from the carburettor and fuel tank (refer to the owner’s manual for the correct procedure). OR Add fuel stabiliser, which will extend the storage life of the petrol remaining in the fuel tank and carburettor. Fill the fuel tank to the recommended maximum level, using treated petrol. Run the engine for at least 5 minutes to allow treated petrol to enter the carburettor before storage.

Lifespan

E10 petrol has a shorter shelf life compared to E5, making it crucial to limit its storage to no more than 30 days to avoid operational issues.

The increased ethanol content in E10 renders it particularly vulnerable to water contamination and fuel separation during storage. This issue is exacerbated when the storage container is not airtight or is left open, allowing the ethanol to absorb moisture from the atmosphere.
