3.1 الأدوات المطلوبة
- مفتاح ربط أو مفتاح ربط قابل للتعديل
- Screwdriver (flathead or Phillips, depending on existing fittings)
- Bucket or towels for residual water
- قطعة قماش للتنظيف
3.2 خطوات التثبيت
- إيقاف تشغيل إمدادات المياه: Locate the shut-off valve for your toilet, usually on the wall or floor near the base of the toilet, and turn it clockwise until the water flow stops.
- Flush and Drain: Flush the toilet to empty the cistern. Hold the flush lever down to drain as much water as possible. Use a sponge or towel to remove any remaining water.
- Remove Cistern Lid: Carefully lift off the cistern lid and set it aside in a safe place.
- Disconnect Old Flush Valve: Depending on your specific Geberit cistern model, the old flush valve may be twisted out, unclipped, or unbolted from the base. Refer to your toilet's original manual if available.
- Clean Cistern Base: Clean the area where the flush valve sits to ensure a good seal for the new part.
- تركيب صمام تدفق جديد: Insert the new Geberit Twinco Bell Flush Valve Mechanism into the opening at the bottom of the cistern. Ensure it is seated correctly and securely. If there are retaining nuts or clips, tighten them appropriately, but do not overtighten.
- Reconnect Water Supply: Slowly turn the water shut-off valve counter-clockwise to restore water supply to the cistern.
- التحقق من التسريبات: Allow the cistern to fill. Carefully inspect all connections for any signs of leaks. If leaks are present, turn off the water supply and re-check the installation and seals.
- اختبار التدفق: Once the cistern is full and no leaks are detected, perform several test flushes to ensure the mechanism operates smoothly and the toilet flushes correctly.
- Replace Cistern Lid: Carefully place the cistern lid back on.
4. Operating the Flush Valve
The Geberit Twinco Bell Flush Valve Mechanism is designed for standard toilet flushing operations. When the flush button or lever is activated, the mechanism lifts, allowing water from the cistern to flow into the toilet bowl, initiating the flush cycle. Once the desired amount of water has been released, the mechanism reseats, and the cistern begins to refill.
This specific model is a complete bell-type flush valve, which typically provides a single, full flush. Ensure the flush button or lever is fully depressed and released for proper operation.
5. الصيانة
Regular maintenance can extend the life of your flush valve and prevent common toilet issues.
5.1 التنظيف
- Periodically inspect the flush valve for mineral deposits or debris, especially in areas with hard water.
- Turn off the water supply and drain the cistern as described in Section 3.2.
- Carefully remove the flush valve if necessary (refer to installation steps in reverse).
- Clean components with a soft brush and a mild, non-abrasive cleaner. Avoid harsh chemicals that could damage plastic or rubber parts.
- اشطفها جيدًا ثم أعد تجميعها.
5.2 التفتيش
- Check the rubber seal at the base of the flush valve for wear, cracks, or deformation. A worn seal is a common cause of continuous running water.
- Ensure all moving parts operate freely without obstruction.
