The A2000 Pressure Plumber is the 21st Century way to clear obstructed and slow moving drains quickly and safely without using acids or harsh chemicals. Even stubborn obstructions caused by hair, soap build up and fat can be removed in seconds using the Pressure Plumber’s unique controlled pressure system. Simply fill your sink or bath with enough water to cover the green cap, form a water tight seal over the overflow and press the Pressure Plumber to send a jet of pressurised gas into the drain. This forces the blockage clear from the pipe and the sink will drain once again! Can be used on all types of interior drains and is harmless to sound plumbing. Contains no CFCs. Refills also available.
