There are generally two reasons for low water pressure in high-pressure cleaning machines: internal factors and external factors.

1. Internal factors

The main internal factors include seal wear, pressure relief valve breakage leading to abnormal pressure regulation, nozzle wear or damage, which may all cause insufficient pressure.

Solution: Replace the damaged parts.

2. External factors

External factors often manifest as unclean water supply, insufficient water supply, and clogged water supply filters, which are common faults that most users do not notice. They generally believe that the cleaning equipment is malfunctioning and only inspect the equipment, but cannot find the cause of insufficient pressure.

Solution: Increase the pressure on the water source. If the direct water supply is insufficient, it is recommended to first find a container to store water, as the inflow flow is sufficient. If the filter is clogged, it is recommended to clean it first. If the filter is damaged, it should be replaced with a new one in a timely manner to prevent foreign objects from entering the high-pressure cleaning machine, causing equipment failure and muzzle blockage.
