Frequently Asked Questions

Water flow is the rate water is pushed out of the lance, with the higher the water flow, the larger the amount of water forced and used. It can be measured in litres per hour and is important for removing and washing away dirt on patios and driveways.

This is the force at which the water is pushed out at, the higher the force easier it is to remove dirt. Lighter jobs including cleaning your car and washing patio furniture don't need much pressure as tasks such as cleaning your driveway. The extra bar pressure makes it easier, quicker and will give you better results with a higher pressure.

A lance is the part that is connected to the trigger gun you hold and press to release the water - the lance is a nozzle where the water comes out. You can get different lances or adjustable ones to change the way the water is forced out, which could be as a pencil jet or perhaps a fan depending on the task. Setting it as a pencil jet is perfect for removing stubborn stains on a patio, a fan is better suited for cars where the pressure won't damage the paintwork.

Follow these simple steps to fix this issue

•  Connect the machine to a water supply and turn on the tap.
•  Remove the filter from the water inlet and have it cleaned.
•  Turn on the pressure washer on without the steel pipe and allow it to run until there is no air coming from the spray gun.
•  Check the accessories you are using are correct.
•  If the pressure and suction valves have started to leak and there is water coming out of the casing, or if the machine is throbbing please get in touch with Aquawash Ltd and we can arrange an appointment with you to assess the problems
•  If the pressure washers valve is stuck, we would also recommend getting in touch and we can advise the next course of action.

Clear it immediately as having a clogged nozzle will make the pressure build up in the pump which can quickly damage it.

First make sure your fuel shut-off valve is in the off position which prevents fuel from spilling out. Ensure your pressure washer is secure and not tipping everywhere and make sure other things will not fall on it during the journey.

If you are cleaning a more delicate surface (such as a house) you will want to hold the nozzle roughly 3-5 feet from the surface of the house. For more abrasive and hard materials you will want to hold the nozzle around 6 inches from the surface. The further you are away from the surface the lower the impact pressure will be on it.

Here is our five step guide to cleaning clogged nozzles.

1. Disconnect your spray wand from the gun before cleaning the nozzles
2. Clear the nozzle with a small rigid piece of wire (perhaps a paper clip)
3. Flush the nozzle backwards using water
4. Reconnect the lance to the gun
5. Finally, restart the pressure washer and depress the trigger on the spray gun

If your nozzle is partially or completely plugged, we recommend repeating steps 1-4.

Depending on the use of the pressure washer there are different detergents to help with your cleaning tasks. There are specialist detergents for car cleaning plus ones especially for patio cleaning too. Browse our Detergents range and find the one for you.

We would recommend no longer than a minute, When the trigger isn't pulled, the water will cycle through the pump, and the heat from the pump causing the water to heat which can burn and melt the internal components of the pressure washer.

No, pressure washers fitted with a special High Temperature Pump are designed specifically for hot water use. If you own a cold water machine, running water through the machine will damage the pump and can cause serious defects to the pressure washer.
