The Monument Tools Drain Down Hose is designed for draining down central heating systems. It comes with a hose clip to attach it firmly to the drain-off cock, as well as hook and loop fasteners for storage. The hose is made from silicone rubber which is soft and flexible, and features an anti-kink design so it lies flat once uncoiled, allowing water to drain quickly. At 15 metres long, the hose is suitable for use in most domestic situations and is designed and manufactured in Britain. Specifications: 15m length, 12mm internal diameter, 19mm outside diameter.
