The most common cause of a temperature and pressure relief valve leaking is simply malfunction due to age. After years of use, the t&p valve can be too old to work properly. In this case, simply replacing the t&p valve should fix the problem. If the temperature and pressure relief valve is faulty, it can also leak.
