I purchased two of these devices and originally did not return them due to constant dripping because I was informed that it was my problem due to water from an RO filtration system that I was led to believe did not deliver sufficient water pressure. I believed that I could install an inline pump to increase the pressure. The problem is with the device and its vented faucet. If I were to install an unvented faucet it would probably explode the heater, so I turn it off and will eventually discard it and replace with a better device.
