The gas pressure to your house is controlled by the meter governor which
is
the property of the gas supplier and is not to be interfered with by you
or
by anyone other than the gas supplier/transporter. If your gas pressure
is
steadily getting lower it is indicative of perhaps a blockage building
up in
the governor filter (if there is one) or a problem in the supply main.
You
may also have a problem in the sizing of your house interior pipework.
Whatever the actual problem you can connect your manometer to the meter
test
point and measure the governed pressure under load. This should be about
21millibar.
If the pressure is significantly lower then your course of action is to
contact the supplier who's telephone droid will recite the usual litany
about turning off the supply and opening all doors and windows etc
before
sending a man in a van along to sort it out.
Don't start messing about with any of the gas system unless you have
read Ed
Sirrets gas FAQ "AND" you are competent to do so. (Your comment about
"I've
heard that--------" makes me wonder if you really are)



Well, the "CORGI" man that came to certify my install (and found all just
fine)
twiddled the gas meter regulator to give the correct 21 mBar - it was a
bit low
apparently.
Didn't involve BG though !


Ah! But he KNEW what he was doing :-)
