enviiFOG Klear – Strong Drain Odour Remover & Unblocker, Enzyme Drain Cleaner Breaks Down Grease & Fats in Kitchen Drains & Septic Tanks, 12 Tablets

It’s hard to say how well this works with clearing the drains however since using this my septic tank has worked better. I use this along with the toilet tablets once a month and have not had any problems since. Easy to use and good value

Had a blocked drain which had to be cleared out. Hopefully, regular use will prevent further blockages.

Been using this every month for the last eighteen months and it is massively effective. The fall on our drain is very shallow and it used to clog regularly. Clearing it was messy and stinky and expensive. This stuff keeps it running clear with no foul odours, no calls to the drainer, and no toxic cleaners to kill our septic tank.

using this to enable the clearing of pipes, not entirely sure if they work or not to be honest but benefit of the doubt.

Works well

Like most on here, I had an drainage issue from my treatment plant. I had it emptied the day after I realised it was nearly overflowing and was advised I would need a new drainage field / soak away. With the cost being £1000+, I went looking for other solutions as the install was only 3-4 years ago. I purchased these and took a stab in the dark the blockage was caused by grease. Upon first use I used 3 tablets devolved and poured 1 directly in the tank and the others as instructed. The next day there was no change and the level was slowly rising up again. I then purchased some drainage rods and rodded the outlet pipe. That also seemed to make very little difference. I added more FOG tablets direct to the tank. The next morning the level had started to go down! Slowly but going down at least. Day 4, the tank was back to normal level . My opinion is that the combination of the two allowed the speedy results seen. I will.be keeping up with the treatment going forward.

This is such an easy way after a sink problem to make sure one keeps the sink (kitchen) clean and smelling healthy. The individually wrapped tablet a bonus for me!
