The Pneumatic Drain Unblocker can be used to quickly clear most blockages in sinks, basins, baths, showers, washing machines, dish washers, WC’s etc. The set comprises the pressure gun plus four adaptors to enable the tool to be used with both 1.25″ and 1.5″ waste outlets from sinks, baths etc, shower trays and WC’s. A few pumps of the incorporated hand pump charges the gun and having fitted the appropriate adaptor produces a compressed air charge in the pressure gun. Place the adaptor over the blocked outlet and squeeze the trigger. A slug of compressed air breaks up the blocked and the water flushes the pipe clean. This can be used as a regular maintenance tool for keep waste pipes clean and free running. No chemicals or other hazardous products are used when clearing the blockage.
