BIO-ENZYM Ltd Industrial strength biological enzyme treatment for grease traps and waste pipes

we have had a grease trap inline to our septic tank in france (4 bedroom house) for about 4 years and twice a year my OH has faithfully dug out about 5 inches of solid fat from the top of our trap - not pleasant work - this year as i sourced new eco tablets for the septic tank i discovered this product - and bought it to see if it would ease the workload - yesterday after 3 weeks we uncovered the trap and - brilliant - only a wafer thin layer of fat in one section and really good looking waste in the rest - no work needed!!i have also noticed that the septic tank (despite having two hi-stack carbon filters) always gave off an odour first thing in the morning - this has disappeared since using the new treatment (which has to be easily mixed and poured down each outlet from the house leading to the the trap and tank)i had a few questions to ask BIO-ENZYM prior to purchase but their communication was fast/ first class and extremely helpfulwill certainly be buying more of this so that i have it in to redo in the 3-6 months suggested by bio-enzym
