Thank you for your question, Marty! Model 59436-SS-PK is tested to perform up to 80 psi, however a small amount of water may still drip out of the Touch-Clean spray holes when switching modes as this is a normal release of pressure. This may also occur once the unit is turned off so as to allow drainage to prevent potential stagnant water.
Best regards, Edward
