Method 1: Measure with a specialized instrument (pressure gauge).

Operating method: Connect the pressure gauge to the angle valve and measure.

Criterion: Pressure of the inlet water (dynamic pressure): 0.15-0.75MPa (1.5kg ~ 7.5kg)

Method 2: Measure with a non-specialized tool.

Operating method: Turn on the angle valve (the original angle valve in the customer's house), collect water from the inlet hose for 10s with the help of a bucket, turn off the angle valve, pour the collected water into more than 5 empty ordinary 500ml mineral water bottles.

Criterion: If the collected water is more than 2.5L, the flush effect will be good.

Note: For a toilet with requirements for the water pressure and the water flow, measure before installation and make sure the inlet water flow is stable.
