Catalysis of the reaction: RPO-R' + H2O = RPOOH + R'H. This reaction is the hydrolysis of any phosphoric ester bond, any ester formed from orthophosphoric acid, O=P(OH)3. Catalysis of the hydrolysis of phosphoric monoesters, releasing inorganic phosphate. Catalysis of the conversion of phosphatidylinositol-3-phosphate, phosphatidylinositol-4-phosphate, and phosphatidylinositol-3,5-bisphosphate, but not PI-4,5-bisphosphate, to phosphatidylinositol; PPIPase activity is a key regulator of membrane trafficking and actin cytoskeleton organization.
