The Arctic Hayes Rapid Radrain Radiator Draining Kit will drain a radiator in just 15 minutes compared to 45 minutes when using other methods. Clean and quick, it helps avoid unnecessary mess and damage to floors and carpets from spillage. The water drains into a strong, reusable plastic bag. The bag can then be disconnected and drained easily. The bag will hold approx. 15 litres of water. For maximum protection always work with plumb-pads or absorbent sheeting.
