What is a buffer tank?
I've been getting this question a lot on the comments on my videos. What is the blue bin used for?
A buffer tank in pressure washing acts as a water reservoir between the main water supply (like a garden hose) and the pressure washer pump. Its primary use is to prevent pump damage and maintain consistent pressure by ensuring the machine never runs out of water, which is especially crucial when the local water source flows slower than the litres-per-minute (LPM) requirement of a heavy-duty professional pressure washer.
Additionally, it absorbs sudden changes in water flow and pressure when the trigger gun is released, protecting the system from overheating and extending the lifespan of the equipment.
