“These types of water treatment devices for softening water going to espresso machines used to be more common. Today, most installations choose a replaceable and throw-away cartridge. A few coffee shops still prefer this inexpensive option. The model supplied by Espresso Parts is solid, dependable, and straightforward.”
“I am enjoying this softener very much. It is providing water to my single brew head espresso machine. There is no effect on the flavor of the water-it remains neutral.
The copy of this softener I received has a faulty three position valve. When changing from the machine supply position to the off position, water is passed through to the pressure relief outlet. This causes a puddle every time. Also, if I open the valve completely to the machine supply position, water will also pass through to the pressure relief outlet.
I think I got lucky and drew a bad valve. I don't want to be on hard water while returning and replacing the product, and I don't want my machine to be down either. I found that if I open the machine supply position nearly completely, but not all the way, it will seal and not pass water to the pressure relief outlet.
I would recommend this product to any espresso machine owner. It is well built and a good size for single or dual head machines. Time to recharge is very reasonable.”
