INITIAL DRAIN TREATMENT-Treat your drains with Fuller Drain Line & Septic Tank Cleaner for three days in a row.
1. Run warm water into the drain before treatment.
2. Pour 1-1/2 to 3 ounces of Fuller Drain Line & Septic Tank Cleaner down the drain.
3. If the area of build-up is beyond the drain where the cleaner is added, a minimal amount of water should be added to sweep the treatment into the problem area.FOR BEST RESULTS-Do not run water for 6 to 8 hours. It may be easiest to apply treatment at bedtime or before leaving for the day. If tough drains still run slow after initial use, plunge and repeat 3-day start-up treatment.
If you wish to treat several drains in a multi-story building, treat lowest drain first to prevent dislodged materials from clogging drains on lower floors.
TO KEEP PIPES RUNNING CLEAR-Repeat treatment every two to four weeks.
SEPTIC TANK TREATMENT-For a 1000 to 1500 gallon capacity septic tank, flush one half bottle (16 ounces) down the toilet bowl each month. For other sizes of septic tanks, adjust treatment accordingly.
