Hello, I've been asked what my method is for improving the reliability of water gauges against trapped air bubbles and false readings. It is actually quite simple and anybody can retrofit it to water gauges with glass tubes:
Just take a piece of metal wire (non-rusting) and insert it down the glass tube. The wire inside helps the air bubbles that form during boiling move up, they don't get trapped any more, thereby ensuring a reliable water level reading.

Here's a picture of my set-up:


Let me know if you try this method too.

That sounds brilliantly simple!

I have done just that and it works just great, especially in my Wharfedale Boiler.
Go on folks give it a try.......

Cheers and any more steamy tips can also be passed on thru this thread........

Glad to hear it worked for you too!

But, the question is - - WHY does it work?

[Colin Bishop]

I would assume it is something to do with breaking surface tension.

Agreed Colin and I for one will certainly be trying it.  The interesting thing now is whether it affects the level sensor of the old Cheddar Boiler level sensor.  If this works to give a more reliable level indication and the sensor still works then the biggest problem with that level controller will have been solved in one go with nothing more than a piece of copper wire.

I can't wait to try it out!

how about some fiber optic ?

That is quite correct.

I tried this idea shortly after reading it, and WOW what a difference !! No more trapped air bubbles !!

Thanks,,,,,i have don it  on 4 boilers ,,,and my friends have don it to,,,,,,,,,,Works perfeckt

It' nice to read that you had good results. Why don't you post some pictures?
