Brown heads on an underfloor manifold (Why?)

magnethead · 2018-09-06 10:02:08

Hi There, Why do these once clear plastic flowmeter things, turn brown over a few years? Too much Iron in the water? It's a sealed system...Just wondering if something is breaking down or reacting? Like it does with an old Boiler, rad situation, this would happen without inhibitor in the system.

Probably not enough or no inhibitor added to the system when new.

Do you have any problem with having to repressurize often?

I'll be meeting the plumber who did this (sisters house) on Monday, I'l ask about the inhibitor, Not sure if it's being repressureized at all since install 5 years back.
