If you are unhappy with your purchase for any reason you can return the items to us for a full refund within 14 days of receiving or collecting your order. Unless agreed with Boswells a return will be required for the refund to be completed. Within the UK we provide a freepost returns service. If the items require collection due to size or weight or is requested by the customer the cost of the collection will be deducted from the refund value.

Outgoing postage refunds: The maximum postage that will be refunded is the current least expensive delivery charge offered by Boswells for your region. In the UK this would be our Saver charge and outside of the UK the Airmail charge. As these can change over time please see our Help on Delivery page for exact costs. This means that customers choosing a more expensive despatch service such as Standard or Express in the UK or Courier overseas will receive a partial postage refund unless the delivery service did not meet its requirements.

A small number of items are excluded from return for common-sense reasons and these are marked as non-returnable on their product page. All returns must be agreed in writing with Boswells before customer action is taken.

For more information and to see any exclusions to the above rules please see Help on Cancellations and Refunds page.

HG 132 Liquid Drain Unblocker 1L - unavailable


HG Liquid Drain Unblocker is a unique, safe, but extremely powerful unblocker that offers many advantages. It does not have to be diluted, thus reducing the chance of splashing. It does not foam or splash when poured into the drain. Unlike other granular unblocking agents, it cannot make the blockage worse and does not harm plastic drainpipes.

Directions for use: Carefully pour 300ml (approx 3 cups) into the blocked drain. Leave to pentrate for about 30 minutes and then rinse vigourously with water. Where there is a stubborn blockage fill the sink with warm water and add 300ml of the unblocker and leave to stand overnight. Rinse with warm water in the morning. The HG Liquid Drain Unblocker is heavier than the water so it will gradually sink through the water to the blockage. The combination of the action of the unblocker and the pressure from the water should remove the stubborn blockage. If you have a blockage caused by food remnants and grease you will need a different type of action and we recommend the HG Kitchen Drain Unblocker. If you have a particularly stubborn blockage that is not specific to kitchen waste we recommend the HG Duo Unblocker. Warning: Do not use on aluminium or zinc or gold plated fixtures. The unblocker will not work on cement or metal object blockages.
