This good quality concealed toilet cistern includes WRAS-approved filler and flush fittings and dual flush, with an attractive chrome button. The cistern is ideal for use with back to wall toilets and provides 3 and 6 litre flush options. For a budget cistern, this product offers some of the best quality fittings around. While most budget cisterns will be fitted with PVC seals around the toilet pan's water inlet, this one has a reliable seal made of rubber making this cistern both installer friendly and effective. The polystyrene packaging (if carefully removed) can be used as an insulation jacket, if you choose, to help prevent the build-up of condensation in the cavity. A 10 year quality-backing manufacturer's guarantee comes with this product.
