Advanced Gel DU 490ml Drain Unblocker - Makes 8 Litres

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. Advanced Gel DU is designed for systems where a condensate pump is fitted.

• 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
