Here are some of the questions we will ask you to determine the necessary doses:
What is the diameter of the line?
How long is the portion of line where grease is accumulating?
How many manholes are involved?
How many restaurants or other high grease generators are on the line?
Historically, where are your most troublesome sections of line?
Do these lines have sags?
Applying EHC-33™ is a simple process. It comes packaged in 8 oz. water soluble packets. It is safe to handle and requires no pre-mixing, pre-measuring or pre-soaking. Simply open the manhole and drop the packet into the flow of the line.
If you are a new user, we suggest that you begin the program in a historically troublesome line. Our experience tells us that virtually every operator contends with a line that frequently backs up.
Occasionally, a backup occurs when buildup is being removed from the line by EHC-33™. Sometimes the grease buildup falls off in large pieces, blocking the line. For this reason, many operators choose to mechanically clean the line before starting the program, then apply EHC-33™ to keep it clean.
The Cleanup/Inoculation Phase
The line to be treated should be inoculated with EHC-33™ in 500-foot sections. This phase accomplishes the following:
Clears the line so that the grease coming from upstream has a place to go
Establishes a grease eating bacteria population that continues to consume grease
Starting at the downstream section, the line is treated for four days. Then the next 500-foot section upstream is treated in the same manner until the entire line has received its initial dose. If you are treating more than 1,000 feet, it will be necessary to start the maintenance dose in the first 1,000-foot section while beginning the inoculation phase in the upstream section.
After the initial doses have been completed, maintenance doses begin. You may treat up to one mile of line from one spot. Simply take the maintenance dose and multiply by 5.2.
We recommend that after the maintenance dose is begun, you inspect the sewer line every week for at least four or five manholes to monitor for grease buildup. If after six months or so you have no buildup, cut your maintenance dose by 50 percent and continue to monitor the line for buildup.
Many operators choose to apply the product on a designated day of the week. For particularly troublesome lines, we recommend the weekly dose be divided in half and be put in the line twice a week. Monday and Friday are generally good days because restaurants are busiest on weekends and a lot of grease is generated. This is not a hard and fast rule. You may choose other days. However, it is important to be consistent. Try to stay with the days you choose. If the program becomes inconsistent, the results will be inconsistent.
