The maker's water guidance
From Slayer Espresso's general guidance.
pH: 7–9
“Water Treatment Requirements ... pH: 7-9”
Total hardness: 2–6 grains
“Water Treatment Requirements ... Total Hardness: 2-6 grains”
Total dissolved solids (TDS): 50–200 ppm
“Water Treatment Requirements ... TDS: 50-200 ppm”
Total alkalinity: 40–100 ppm
“Water Treatment Requirements ... Alkalinity: 40-100 ppm”
Chloride: up to 30 ppm
“Water Treatment Requirements ... Chloride: <30 ppm”
Silica: up to 10 ppm
“Water Treatment Requirements ... Silica: <10 ppm”
Chloramine: up to 0.1 ppm
“Water Treatment Requirements ... Chloramine: <.1 ppm”
Total chlorine: up to 0.1 ppm
“Water Treatment Requirements ... Chlorine: <.1 ppm”
Chloride: up to 30 ppm
“Chlorides also encourage pitting corrosion, which causes damage to the machine. Incoming water should have no more than 30ppm chloride content.”
Hardness, highest: up to 9 grains
“Reverse osmosis may be a good solution for water in the range of 6-9 grains of hardness and is mandatory for water above 9 grains.”
Total hardness: 2–6 grains
“The desirable range of hardness is 2-6 grains.”
Water filter
“All SLAYER Espresso Machines need to be connected to a carbon water filter to remove chlorine, sediments, odor, and undesirable tastes. This requirement is in addition to any other necessary water filtration systems.”
Remineralization: 75–125 ppm
“When blending minerals with the filtered water, target a TDS (total dissolved solids) value of of 75-125 ppm. Experiment with various TDS levels to determine what produces your preferred taste.”
Water filter
“Carbon filtration is necessary for all machines. For water with 3-5 grains of hardness, carbon filtration is likely the only necessary water treatment.”
Softened water
“An ion exchange system should be used in combination with a carbon filtration system and is especially beneficial for water in the range of 6-9 grains of hardness.”
Warranty
“IMPORTANT: Damage to or failure of your machine due to inadequately treated water is not covered under warranty.”
Testing
“SLAYER recommends testing water pre-and-post filtration by an experienced espresso technician during routinely scheduled Preventative Maintenance.”
Total hardness: 4–5 grains
“The desirable range of hardness is 4-5 grains.”
Water type
“Slayer’s recommended water recipe for ultimate taste and limited scale: pH: 7-9 Total Hardness: 2-6 grains TDS: 50-200 mg/L Alkalinity: 40-100 mg/L Chloride: <30 ppm Silica: <10 ppm Chloramine: <.1 ppm Chlorine: <.1 ppm”
Chloride: up to 30 ppm
“incoming water should have no more than 30ppm chloride content.”
Warranty
“Any and all damage resulting from inadequate water treatment is expressly excluded from the coverage of this warranty.”
Hardness, highest: up to 50 ppm
“Water hardness cannot exceed 50ppm, otherwise a ... water softener is needed”
