The De Vecchi Gaetano DVA LT8 is an indispensable 8-liter water softener designed for Espresso Machines, Ice Machines, or any other equipment necessitating a connection to a main water supply. This water softener tackles the problems caused by hard water, which contains high levels of calcium or magnesium. Hard water can lead to scale formation inside pipes, water heaters, and on espresso machine heat exchanger surfaces of boilers, adversely affecting heat transfer and water flow. It also reacts with soap to form a sticky scum, hindering lather formation which is undesirable for personal hygiene.

The DVA LT8 operates by replacing the calcium and magnesium ions in the water with sodium ions, thus softening the water. This ion replacement occurs as the water flows through a bed of small plastic beads or a chemical matrix called zeolite, both of which are covered with sodium ions. Over time, the beads or zeolite will need regeneration, which involves soaking them in a strong brine solution to displace the accumulated calcium and magnesium ions and replace them with sodium ions. The regeneration process is simple and can be performed with rock salt available at hardware, plumbing, or grocery stores. The DVA LT8 comes standard with 3/8" BSP (British Standard Pipe) fittings, and an adapter may be required to fit supply hoses to the unit. This water softener is engineered for maximum precision, equipped with high-durability grinding wheels, and a unique millimeter-level dosing device for easy handling even at maximum compression. Its design ensures reduced effort and noise during the coffee grinding process, promising a seamless operation for your commercial espresso machine, and other related equipment. DVA Water Softener Instruction Manual
- Initial Setup:
- Remove the lid (fig. 1, G) and add the required quantity of salt according to the model (see the table at paragraph 2.6).

- Regeneration Process:
- Turn the water inlet tap lever (fig. 1, C) on the left.
- Let the salt water come out from the drain pipe until the water is fresh (around 40 minutes).
- Put the water softener back in service mode by turning the water outlet tap lever back on the left (fig.1, D).
