The heater should come with a fibre sealing washer, but some sealant

More amateur tripe. Appalling.

You put NO compound on the thread. The immersion is supposed to have
none whatsoever. Just clean the surfaces and tighten the immersion. The
fibre washer may initially weep. But as it absorbs water it will expand
making the seal. Try this first. If still a leak after the system has
heated up, take it off and then lightly smear compound on both edges of
the washer.

Great way to do things. If it doesn't work, try again. Like hack sawing
through plastic pipe.

Remind us once again how you earn a living? But obviously with no repeat
customers?

Putting compound on the thread with act like glue and weld it in, in
time, making some of them near impossible to remove.

Love the 'compound' bit. Anyone with more than one brain cell would name
the product on a DIY group.
