Drain Cleaning a VERY Blocked Drain - Drain Cleaning

Cleaning a blocked drain from the grease trap at a commercial fast food outlet. Using a water jetter to clear the blocked drain which was full of food scraps and rubbish. The water jetter cleans the inside of the drain thoroughly which the old school mechanical auger does not. Once we completed the clearing of the blocked drain, we flush and test all drains throughout the property to make sure all is 100% clear.
