At approximately 9:00 am I received a call from a customer stating that when he
tried to start up the boiler it wasn’t igniting, meaning they had no hot water or
heating, which the customer was distressed about. Instantly I started to diagnose
the problem before I got to the property, and I knew that in most cases where
the boiler isn't igniting its most likely due to a faulty ignition electrode.
When I arrived at the property, I went to the boiler and tried to start it however
there was nothing. it wasn’t making the usual clicking sound to show that the
boiler is igniting. I also went to the taps to see if hot water was coming out
however that was also absent which indicated to me that i needed to look inside
the boiler. Before I done that, I conducted my visual inspection starting at the top
of the meter by making sure that the Emergency Control Valve (ECV) falls to the
OFF position and that there is a label indicating what position means the ECV is
on or off. Gradually I worked my way down the meter analysing that the
pipework/anaconda is in good condition (no paint or dents/holes), the brackets
holding the meter are secure and that the tamper seal has not been tampered
with and is sitting correctly on the regulator. When I finished my inspection and
was certain that I checked everything correctly, I moved on to the tightness test.
Prior to starting the tightness test I made sure that the U-gauge I was using was
in good working condition and that the water inside of it was level to zero-zero
millibar. I performed this tightness test to make sure that the installation that
was done before is safe. The first test that I performed on the meter was the let–
by test, to ensure that there is no gas that can pass through the valve when it is
turned off, so I isolated all appliances starting farthest from the meter. I removed
the screw from the test point and replaced it with the tube from the U-gauge. I
then put the ECV to the on position, to make pressure, so that the reading within
the U-gauge was at 10 mb (millibar) and then timed it to run for 1 minute. Once I
was fulfilled with my let-by test that proved no gas was passing through when
the ECV was in the off position I moved on to conducting my temperature
stabilisation. Temperature stabilisation is done to allow the water and gas in the
U-gauge to equalise in temperature so the reading from the tightness test will be
accurate.
With the tube still attached to the test point I made sure that the reading on the
U-gauge was back on its original position (zero-zero millibar). I Then turned the
ECV to the on position to allow the pressure to let the water rise to 20 mb,
subsequently timing it for 1 minute. When I was done with my temperature
stabilisation and content that my results were adequate, I moved on to the
tightness test. The tightness test is implemented to test the entire installation
(all pipework and appliances downstream of the meter) for gas escapes. Firstly, I
made sure that the U-gauge was back to the starting off point at zero-zero
millibars, then I turned the ECV to the on position to allow the pressure from the
