Adriatica Water Softener — Monobloc with 8100 Valve
Adriatica monobloc water softener with 8100 volumetric valve: 7 capacities (10–30 L), Dowex food-grade resin, SS bypass, 3 colours. DIMM stock Belgium & France.
General overview
The Adriatica is a monobloc water softener fitted with the 8100 volumetric electronic valve. Its monobloc design integrates the resin vessel directly inside the brine tank, significantly reducing the floor footprint compared with a conventional twin-tank system. Available in seven capacities — 10 L, 14 L, 16 L, 18 L, 22 L, 25 L and 30 L — and in three colours (black, white with blue cap, white), the Adriatica covers every residential need, from a studio apartment to a large family home.
The cabinet is moulded from injection-moulded polystyrene, reinforced with lateral stiffeners that guarantee structural rigidity even when the brine tank is loaded to its full 80 kg capacity. This mechanical robustness, combined with a high-quality composite resin vessel, gives the Adriatica remarkable longevity.
DIMM distributes the Adriatica range in Belgium and France. All models are held in permanent stock, with fast delivery and full technical support.
The 8100 valve — standard equipment
The Adriatica is primarily sold with the 8100 valve, a reliable and proven volumetric electronic valve. This controller manages the entire regeneration cycle autonomously.
Valve 8100 features
- Intuitive programming — large backlit LCD screen and 3 push buttons for quick setup
- 6 adjustable cycles — optimised regeneration based on consumption profile
- Volumetric regeneration — the cycle triggers automatically when resin capacity is depleted, measured by a built-in volumetric meter
- Programmable time-clock regeneration — option to force a cycle at regular intervals to prevent bacterial stagnation
- Combined mode — blends both modes for optimal management
- Manual override — a single button press triggers a regeneration at any time
Construction and technical specifications
The 8100/1600 valve stands out through the quality of its materials and performance:

- Brass piston with low-friction coating — reduces wear and extends service life
- Hydraulically balanced piston concept — quiet operation under balanced pressure with minimal mechanical stress
- Service flow rate — up to 4.5 m³/h, ideally suited for residential use including high-consumption households
- Compatible vessels — 6", 10" and 12"

Design and monobloc construction
The Adriatica stands apart from conventional softeners through its monobloc architecture. The composite resin vessel is integrated inside the brine tank, delivering several practical advantages:
- Reduced footprint — a single unit instead of two separate components (vessel + tank)
- Simplified plumbing — the stainless steel bypass is included as standard, ready to install
- Clean aesthetics — the monobloc cover features a translucent section that allows the valve status to be checked without dismantling anything
The Adriatica brine tank holds 80 kg of salt, which extends the interval between refills and reduces service visits. The dual-safety brine float protects against overflow and ensures optimal brine concentration at every regeneration.
Available in three colours — black (black tank and cap), white with blue cap, and all-white — the Adriatica blends into a utility room, near the water meter, in a garage or a pantry.
Dowex HCR-S/S resin
The Adriatica is charged with Dowex HCR-S/S resin, a high-performance strong acid cation resin manufactured by Dow Chemical. This resin is widely recognised for its outstanding qualities in drinking water treatment.
Technical properties
- Food grade — Dowex HCR-S/S resin is certified for contact with water intended for human consumption
- ACS approved — compliant with the French Sanitary Conformity Attestation
- Particle size 300–1200 µm — controlled size distribution for efficient ion exchange and manageable pressure drop
- High exchange capacity — stable performance over long periods, even after thousands of regeneration cycles
Good to know — The fine particle size (300–1200 µm) of Dowex HCR-S/S resin provides a larger exchange surface per unit volume, which improves treatment efficiency and reduces salt consumption per regeneration cycle.
The resin is housed in a high-quality structural composite vessel, engineered to withstand service pressures and repeated regeneration cycles throughout the lifetime of the unit.

Sizing — Which model to choose?
Choosing the right resin volume depends on the number of occupants and the hardness of the incoming water. The table below provides recommendations for hardness below 35 °TH:
| Model | Resin volume | Number of people | Typical use |
|---|---|---|---|
| Adriatica 10 L | 10 litres | 1 person | Studio, compact apartment |
| Adriatica 14 L | 14 litres | 1 to 2 people | Small apartment |
| Adriatica 16 L | 16 litres | 2 to 3 people | Small apartment, couple |
| Adriatica 18 L | 18 litres | 2 to 4 people | Apartment or mid-size house |
| Adriatica 22 L | 22 litres | 4 to 6 people | Family home |
| Adriatica 25 L | 25 litres | 6 to 9 people | Large house, high consumption |
| Adriatica 30 L | 30 litres | 6 to 9 people | Very large dwelling, very hard water |
Sizing example — For a 4-person household with water at 30 °TH, consuming an average of 500 litres per day: the 22 L model offers a good balance between regeneration frequency and footprint. If hardness exceeds 35 °TH, stepping up to the 25 L model is advisable to space out regenerations.
For very hard water (above 35 °TH) or dwellings with a large number of water outlets, contact the DIMM technical team for tailored sizing based on your water analysis.
Installation and connection
The Adriatica has been designed for quick and straightforward installation by any qualified plumber. The stainless steel bypass supplied as standard greatly simplifies the plumbing work.
Installation steps
- Position the softener close to the main water inlet, on a flat and stable surface, protected from frost
- Connect the water inlet and outlet via the supplied stainless steel bypass
- Connect the drain hose to a trap or drain point
- Plug in the Fleck valve power supply (transformer provided)
- Fill the brine tank with tablet salt (regeneration salt)
- Program the inlet hardness and resin volume on the SXT controller
- Run an initial regeneration cycle to commission the resin
- Adjust the mixing valve to achieve the desired residual hardness
Regulatory requirement — A non-return valve must be installed upstream of the softener, in accordance with Belgian and French regulations, to prevent treated water from flowing back into the public supply network. Ensure that regeneration waste water is properly drained.
Placement recommendations
The Adriatica should be installed in a frost-free, ventilated location close to a drain. A utility room, garage or pantry are ideal. Allow enough clearance above the unit for access to the brine tank and valve.
Routine maintenance
The Adriatica softener is designed to operate autonomously with minimal upkeep. A few simple tasks are all that is needed to ensure long-lasting performance.
- Salt level — Check the level in the tank once a month and top up with tablet salt. Avoid rock salt, which contains impurities that can clog the brine system
- Brine tank cleaning — Drain and clean the brine tank once a year to remove deposits and any salt bridges
- Resin cleaner — An annual treatment with a dedicated resin cleaner (e.g. Resinol or equivalent) extends resin exchange capacity and prevents bacterial contamination
- Hardness check — Test residual hardness at the softener outlet with a TH test kit every 6 months
- Float inspection — Check that the dual-safety float is functioning correctly during the annual tank clean
- Professional service — DIMM recommends an annual inspection by an authorised technician to check the valve, resin and the entire hydraulic circuit
