Red "inhibitor"

[Susiep]

Hi everyone,

In our block we have so I am led to believe there is a indirect heating system which has worked well for approximately 20+ years. Approximately 4 years ago our boiler was swapped out of with a Megaflo system. Sunday I went to have a shower and was greeted with a pink / red coloured liquid. I believe this is possibly inhibitor fluid that has some how got into the shower hot water system (all taps also have red water when hot is selected, cold is still white water). I asked security if any one else had raised any concerns (800 apartments) no only you was the reply. I am wondering how this liquid could have got into the shower system as it is a closed system? I left the shower running for 30 minutes (15l minute) but the colour remained?

Does anyone have any ideas as to where I should look to resolve this issue?

I will probably be shouted down by every man on this website, but if you think the inhibitor has managed to get in to the DHW (domestic hot water) circuit I would have thought there must be a leak in the internal coil in your DHW cylinder. If it is a fully indirect system then I think the hot water is heated via a coil that runs through your cylinder which heats the water from the CH (central heating) system as opposed to direct, which is heated through an immersion heater. If the coil inside your cylinder has shafted itself then you could be getting all the crap out of the CH circuit mixing with your DHW. It may not be anything too harmful as a lot of inhibitors are just a balancing substance to prevent hard water and mixed metals buggering up the internal gubbins of the system, but is probably not recommended by L'Oreal. I am probably wrong, but worth checking I would imagine.

Sealed heating system = 1.5bar working pressure with a 3 bar PRV
Sealed UV hot water system = 3bar working presure

Im thinking if the coil was holed the heating system would be discharging via the PRV too because of the 3 bar pressure added to it via the mains.

You havent had an expansion vessel changed/added to the hot water system and they have used a red vessel (they rust with oxygenated fresh water) is the cold the main or just the hot?

I'd be more concerned with the cold water being white

I think that you need a professional diagnosis because it could be dangerous either to you or to the system.
