Constantly dripping pressure relief pipe?

start off by replacing the valve. be aware though that the pressure gauge may be faulty. unless you have manually opened the valve then make sure that the filling loop is off after use and re-pressurise the expansion vessel as the valve wouldn't have started leaking for no reason.

Replace the pressure relief valve Dave - they are notorious for not shutting off fully once opened. Cost around a tenner.
