Water in Firebox

Hello, in need of some pointers!

I have a Foden 4 1/2” that is steady dripping water directly down into the fire!

Is this a fuseable plug issue as it has been retubed quite recently in over the last year.

I’m an Agricultural mechanic so any pointers to dive into this is greatly appreciated.

Sounds like either the plugs leaking around the threads or the leads wasted out of it.

If you put the shovel in and it ends up getting wet directly below the plug then thats the issue, I'd start by changing the plug, you should carry a spare anyway, along with things like a gauge glass.

Yes, I do have a spare plug and will have a go at replacing it!

Thanks for the reply.
