Hot water coming from expansion pipe into header tank.

[Phill Peck]

If that arrived to me as a pre piped cyl I'd be somewhat disappointed!

I can see that the bypass connection above the pump is not an end feed fitting so maybe it is part of a kit.

Either way the problem is the air Sep. Cleaning/replacing bother require it to be removed

Was it "pre-plumbed" into the ark before you acquired it?

No sorry, 2 spanners, one for 22mm and 15mm compression fittings.

One adjustable will be fine.

But what are you waiting for?

Every hour you run with pump over the more new oxygen is drawn into the system and is rusting the rads from the inside.

Have any shown the pin hole leaks yet?
