Is my hot tank coil split

[dazzlerpalmer]

I am in the process of updating all my rads in the house.

I am draining and refilling the system alot as I do each couple of rads.

I was replacing a oldered T piece the other night and because of the water in the pipe I could not get the pipe hot enough. I cut the T piece off with a jigsaw (broke the blade) and remade it with a compression T.

The other night the wife was having a bath and she was sharing it with a piece of the hacksaw blade. I suspect the blade segment has travelled into the coil and mixed with the domestic water. Either that or it has been collected up in a wet towel and found its way into the bath,

How can I tell if the coil is leaking. I will be filling the central heating with flush and inhibitor soon and obviously I don't want to waste it.

I thought of stopping the header tank feed and checking the level. Any better suggestions (dye etc)

Thanks

I`d go with the wet towel theory

I`d go with the wet towel theory

ditto

watch the water levels if the coil is split the f&e tank will usually start rising

thanks for your help again

I will keep and eye on the F&E tank.

What level will it usually rise to ?

I was kind of worried the drain downs and refills is stressing the coil.

Tank approx 15 years old. I will soon be de-sludging and putting inhibitor in.
Cheers

It'll go up and down as the water in the system heats and cools. It'll only fill from the big cold tank if that has a higher water level.
It should be at a low enough level to allow for expansion without overflowing.
