AdvancedGel DU

Drain Unblocker

  • The heavy-duty formula will clear organic and inorganic blockages
  • Heavier than water, it will sink and find the blockage
  • Safe to use with condensate pumps

Product Code
5×490ml – S010461GB

Condensate run-off from the coil will drain away slowly. If the coil is very dirty, some of this dirt will be carried into the condensate tray. Sludge and slime building up in the standing water in the tray will eventually run into the drain – causing blockages. Overflow from the tray may damage decoration and furnishings. AdvancedGel DU is designed for systems where a condensate pump is fitted.

How to ship Gels

Advanced Gels are classed as ‘Limited quantities’ (LQ) and can legally ship with any courier.

The majority of our other concentrate products are classed as ‘hazardous’ and would require a full ADR driver.


For all liquids, hazardous or not, labelling is required when shipping, on outer boxes, including:-
Contact details, weights and this way up arrows.

With ‘Limited Quantities’, if the wholesaler breaks down our outer box, they will need to transfer the ‘LQ’ diamond and the other information found on our packaging, to the new outer.
