You just pluged in one end of the hose to the end of your A/C drain line (3/4 inch PVC pipe) and the hose from your shop vac to the other end and it sucked ALL of the water and gunk out of the line.
The clear visual inspection tube really helps to know if you are done or if the wet vac had even started sucking any water.
It includes an adaptor for 3/4" pvc as this is used on many HVAC systems for drainage.
This device can effectively solve the problems of pipe angles and the size of the vacuum hose adapter,When it is connected to the vacuum cleaner, it can thoroughly clean the drainage pipes.
