A reliable water supply is essential for effective pressure washing, but many people don’t realize the system involves more than simply connecting a hose to a machine. The process includes several key components that ensure steady water flow and protect the equipment.
Most pressure washing setups draw water from an external source, such as a hose bib, spigot, or water tank. However, before the water enters the pump, it usually passes through a buffer tank. This tank acts as a reservoir, ensuring a consistent water supply even if the external source has fluctuations in pressure or flow rate. Without a buffer tank, the pump could “starve” for water, leading to cavitation—a damaging condition where air bubbles form inside the pump.
Once water is held in the buffer tank, the pressure washer’s pump pulls from it at the rate needed. From there, the pump pressurizes the water and sends it through the hose and wand, allowing the operator to control the flow and cleaning power with different nozzles or attachments.
The use of a tank provides several benefits: it protects the pump, reduces wear, and allows flexibility for jobs where a direct water hookup isn’t available, such as remote worksites. Some pressure washing contractors even carry large mobile tanks on their trucks or trailers for this reason.
In short, the buffer tank is the silent middleman in the system—making sure the pump always gets a steady water supply so the job can be done safely and effectively.
