I'm in the same area and I kit brew, but I gave up using tap water years ago as it's so hard. I use Asda spring water which is about a quid for 5 litres.
Will this hard water affect the effectiveness for Star San ??
I have tested PH it is circa 7.2 , but isnt this different to water being hard ?Potentially. Star san needs to be kept at (iirc) ph 3. The alkaline minerals in hard water can up the PH so it's not effective anymore. My (London) water is hard but I just dilute the star san with it as it doesn't seem to be hard enough to raise the PH above 3, although it does seem to make it cloudy. You can get loads of PH strips from fleaby for about a quid to test it

Yes , my tap water ph is 7.2 , sorry to be so dim, does this mean i shouldnt use Star San ?I take it you mean your water is PH 7.2? Yes I think this is different to water being hard. Tbh I really try to keep things simple when it comes to water PH, treatment , etc as things can get REALLY complicated. As I understand things if you have 'hard' water (whatever this means as when it comes to water treatment for brewing rather than just for starsan, as I understand things ,there is a difference between hardness and alkalinity) this can effect the PH of your diluted starsan, bringing it above the PH level (of 3) where star san is effective

Thanks, I understand now, my ph test strips only do the mid range so have ordered some full range ones. :thumb:no, its not the PH of your water that counts but the PH of the diluted starsan. iirc stars san in its undiluted form is a concentated acid. when you dilute it with water at the correct ratio of 1.5ml per L the solution becomes PH 3. However hard water can make the PH higher (but not mine even though my water is hard)
