Hi, will this Ozito 800w constant pump hooked up to my rain water tank run a pressure washer no issues?
I have a 500l tank and just wanna use the water to wash my car and boat
Welcome to the Bunnings Workshop community @justsome. It's marvellous to have you join us, and many thanks for your question about water pumps.
Yes, the Ozito 800W constant-pressure pump should have no trouble running your pressure washer from a 500L rainwater tank. With a maximum flow rate of 3,600L/h (or 60L/min), it easily exceeds the 5–15L/min that most domestic pressure washers typically require. Your 500L tank will also provide ample runtime for washing your car or boat — at a flow of 8L/min you’ll have over an hour of continuous use, and even at 15L/min you’ll still get around half an hour of washing time.
Before setting it up, check your pressure washer’s manual to confirm there’s no maximum inlet pressure limit. Most models are fine when connected to a tank pump, but it’s always worth verifying.
The only thing to keep in mind is that the Ozito pump has an automatic flow switch. If you’re frequently starting and stopping with the washer trigger, the pump may cycle on and off rapidly, which can lead to overheating during extended use.
Please let me know if you have any other questions.

Hello @justsome
The Ozito pump does not come with its own filter. It will be necessary to purchase it separately. I propose looking at the Ozito Pre-Filter Kit or the Ozito 25mm Inlet / Outlet Pump Y-Strainer. Both are compatible with the full range of Ozito pumps.
If you have any other questions we can help with, please let us know.
