BWT Perla Seta Duplex Water Softener 125686700

Product Overview

The BWT Perla Seta Duplex Water Softener 125686700 is a premium whole-home water softening system designed for larger homes, higher water consumption, multiple bathrooms, rainfall showers, and hard water conditions. It delivers BWT Pearl Water throughout the home with the capacity, comfort, and control expected from a luxury water treatment system.

The Perla Seta uses a duplex ion exchange design with two softening columns. This helps maintain soft water availability while adapting to changing household water demand. For homes where several fixtures may be used at the same time, the duplex design supports showers, baths, laundry, dishwashers, water heaters, boilers, and connected appliances.

Hard water can leave limescale on fixtures, reduce appliance efficiency, shorten the life of water heaters and boilers, and make cleaning more difficult. By reducing hardness minerals such as calcium and magnesium, the BWT Perla Seta helps protect plumbing systems, bathroom surfaces, glassware, appliances, and heating equipment from scale-related wear and buildup.

The system includes a 5-inch multi-touch display, automatic motorized blending, dry salt storage, ultrasonic salt level monitoring, smart connectivity, and BWT Best Water App compatibility. It also includes advanced AQA safety features, including AQA Watch, AQA Safe, AQA Stop, and optional AQA Guard wireless water sensors for expanded leak monitoring.

Installation Tips

Install the BWT Perla Seta in a frost-protected mechanical room, utility room, or service area with a flat, level floor. The installation area should be protected from chemicals, solvents, fumes, and direct environmental exposure.

A protective pre-filter should be installed upstream of the water softener to help prevent dirt, sediment, and corrosion particles from entering the system. A pressure reducer may be required if incoming water pressure exceeds the approved operating range.

The system requires a nearby drain connection, suitable wastewater routing, and a separate electrical power supply. The rinsing water hose and overflow hose must be routed correctly, must not be restricted, and must maintain the required air gap at the drain connection.

Adequate space should be left above the unit so the Easy Fill cover can open fully for salt refilling. The installation should also allow service access to the front, top, inlet, outlet, drain, and electrical connection areas.

For connected features, confirm suitable GSM reception, Wi-Fi, LAN access, or the intended communication method at the installation location. Optional AQA Guard wireless water sensors can be installed in higher-risk locations for added leak monitoring.

Professional installation is strongly recommended. Local plumbing codes, drinking water regulations, backflow requirements, and drain air gap requirements must be followed.
