Hi,

I have a big green outside oil tank (Home heating etc).

There is a clear thin tube on the outside, with a small floating ball in
which is supposed to be indicative of the amount of oil left in the tank.
At the bottom of the small tube is a button you press to sync the tube
with the tank.

It no longer works and I have no idea how much oil I have without looking
in the tank.

Does anyone know how to fix this problem OR is there another method to
help me?

Thanks

Paul

You say it no longer works? How do you know (sorry to ask such a simple
question). For example is there oil in the tank or has it run out. Ther is
little to go on to diagnose why it has failed. You could remove and clean
the tube if there is a blockage and that gives you an opportunity to see if
pressing the button release oil.

These guages are a potential source of leakage from the platsic tubes
degrading or coming off so some form of in-tank system is often better so
long as the old gauge is removed. For example see
http://www.caldo.co.uk/tank_monitoring.htm.

One way that often gives away the oil level is to go out in the morning
after a heavy dew fall. The oil level is often visible in the dew on the oil
tank. May not be practical as an alternative at all times.
