I’m currently servicing our beer engines, and have discovered black slime in the water jackets which also blocked the silicon hose waterways.
On checking the chiller in the cellar, there are signs of a creamy coloured slime in the water as well. I assume it’s the same thing.
Before I reconnect the clean beer engines, I shall empty the chiller water bath and give it a good clean.
This is the only chiller affected, so I hope it’s a one-off, but are there any recommendations for an additive to the water, to prevent this kind of thing?
I seem to remember someone saying Milton fluid [basically bleach], but I think that this could have an adverse effect on the copper coils.
