Londinium I - Water Recommendation

i stand to be corrected, but i don't believe that raising the permanent hardness will matter for our purposes (use in espresso machine boiler) and the pH is allowed to go up to 8, so i think you should be fine you're absolutely correct about getting rid of the chlorine by running your tap water thro...

Londinium I - Water Recommendation

there are others here who can answer your question more ably than i, however my understanding is that you only need to concern yourself with temporary, or carbonate, hardness as only this aspect precipitates out when the water is heated. with a carbonate hardness value of 89.5mg/L you are about as h...

Fittings in the top of the boiler - Teflon tape or thread lock?

bear in mind the Loxeal & Loctite type products are available in a range of strengths, thread sealing being the weaker range and nut locking being the stronger range but within these ranges the strength also varies - it is important to take the time to read the spec & application sheet on the manufa...
