Don't turn the bidet knob to WASH unless you're sitting on the toilet!
To clean before you use, simply turn the knob to the right and the nozzle will run water over itself.
Take a seat and SLOWLY turn the knob left to determine how much pressure feels comfortable.
The water pressure of your home’s plumbing system will affect the water pressure of your bidet.
When testing the bidet, ROTATE SLOWLY while you figure out how much pressure is comfortable.
If the water pressure is too strong, you can slightly rotate the water supply valve clockwise (righty tighty) to decrease the flow.
