Evening, I've recently moved across from the coffee forums and wondered if I could tap into the forums knowledge. I'm thinking of upgrading from my 2007 classic to a possible end game machine. However, as part of my budget verification, could I ask about my water hardness and content. I.e do I need to also invest in a RO machine too. I'm based in sheffield and I do think we are blessed with really great water but is it suitable for use straight into a machine?

@Rob1is our expert, but your water report looks excellent. I wouldn't have thought you would get much scale build-up at all. Obviously it won't be zero scale build up. I would still recommend filtration to remove some of the other stuff such as chlorine, particulates, off tastes. Something like a Britta jug might be good.

See if you can find a more detailed report from the supplier. You need to know the bicarbonate or alkalinity (expressed "as CaCO3" or not).

@"Rob1"#p12316 I know when I looked a while ago I could download a report. Let me see if I can find it

@"Rob1"#p12316 Yorkshire waters website expands to this [URL=https://i.imgur.com/iLtfz2c.jpg][IMG]https://i.imgur.com/iLtfz2c.jpg[/IMG][/URL] The figure in the image is based on the average calcium. The detailed table suggests a lower value of 3.9mg/l which I think calculates to 9.75 CaCO3?

That's the hardness. You need alkalinity.

@"Rob1"#p12328 thanks! Doing some googling, I can't seen any details on line regarding alkalinity in my area. I'll drop YW a line tomorrow to see if they have further details. Otherwise, I've seen on a home brewers forum that I can test myself and use an alkalinity test such as the salifert alkalinity test kit?

@"Gav86"#p12330 Yeah! A drop kit should do. You can test on 20 ml of water to improve accuracy.

@"Gav86"#p12330 I contacted YW Regarding my water Alkalinity and found them to be very helpful. I have just checked my area again and the YW water report has changed quite a bit.

@"Meldrew"#p12340 thanks for letting me know. Did you call their contact line and ask for details on alkalinity? I'm sure I ran the report a few years ago and was trying to find it but can't for the life of me remember where I could have saved it!

Water composition help

Meldrew You could, yes. You wouldn’t completely eliminate either descaling or regular flushing (service boiler only). With use even a harness of 22mg/l would rise quite quickly in a service boiler.

Rob1 Thanks Rob. Much appreciated. Need to monitor water quality and decide if to get the RO.

Rob1 Hi, so I’ve just done 2 alkalinity drop tests (as I couldn’t believe the first one) and I’m getting a dKH of 0.3 which I think is 0.1071 meq/L or 5.366ppm CaCO3

What would you recommend the alkalinity be, I assume a bit higher than this?

For taste I like between 40-50mg/l. The water will be on the corrosive end of LI. I can’t comment on how much you should be concerned by this, if at all, water will either be scale forming or corrosive at different temperatures, you basically have to decide which way to go. I may decide to go for water that is really good at brew boiler temps but scaling at service boiler temps…..or I may try and find a way of getting hardness and alkalinity without scaling potential (alkalinity would have to come from non-carbonate sources).
