New solar system,losing pressure and skin infection

rolion

Hello,

Got a solar tubes system installed few months ago,new cylinder.
Working fine so far but i seen few things that worries me:

-pressure gauge on the combi boiler drops over couples of weeks from 2.5 to under 1 and require a top-up.
-all members of family reportig skin probles,iritations,infections,rush,spots

Major scare that i heard is that inside the cylinder,it may be a heating coil leaking and mixing it in the domestic water, causing the skin reaction.

Losing pressure could be anywhere in the system:radiators,pump,underfloor,in the ceilling while caused by anything.

Spoke with the plumber and he gave me few reasons,none of them i can believe / validate /trust. So i'm going to take water samples from all major points of entry / exit along the system and bring it for a test.

Anyone been in the same / simillar situation like me !?

Thanks.
