heater pilot lights ok fires up when tap is opened but clicks off quickly and pilot goes out.relights immeadiately,if temperature is reduced main burner stays on longer but stills clicks out and shuts down pilot.diaphram and thermocouple appear ok any ideas?

I agree with the other answer you received. also look @ a flue fault (ie) air intake blocked due to cement work or roughcasting being carried recently restricting the air intake for complete combustion. Easy way to check is to re-light the pilot, turn on the hot water tap and watch the flame through the viewing hole, if the flame starts to lift up away from the burner then it is serching for oxygen and will eventually go out as it cannot find enough oxygen for the gas to burn. Remember in school where they showed you a burning candle and put a glass over it and the flame would rise and go out. Same thing. Not enough air No Fire

Check that the pilot is warming the t/couplr correctly.These have a tendency to burn yellowy and loop upwardly rather than be blue and go at 45 degree angle to t/couple.It seems once the main burner is lit it is pulling the pilot away from the t/couple,hence we get shutdown.
