Grease and fat

When hot oil cools, it can solidify and cling to the sides of your drain, eventually causing a blockage.


Hair is often the culprit for blocked shower drains. As hair accumulates, it forms a "lint ball" that can trap other debris and cause a blockage.

Soap scum

Soap scum can build up on the sides of your drain, just like grease and fat.

Tree roots

If there are trees close to your home, their roots can grow into your drains and cause a blockage.

Foreign objects

Toys, jewellery, and other small objects can quickly become lodged in your drain and cause a blockage.

Electric Eel Drain Clearing

An electric eel is a long, flexible rod inserted into the drain. The eel is then turned on, and the rotating head will clear any blockages in the drain. Electric eels are the most effective way to clear blocked drains, and they're also the quickest and most convenient option. 

Our electric eel drain clearing services are available for both residential and commercial properties. National 1 Plumbing offers a fast and effective electric eel drain clearing service. Our plumbing team will have your drain cleared in no time so that you can get back to your regular routine.

High-Pressure Root Cutting
