5 Litre Heavy Duty Sink & Drain Unblocker | Strong Cleaning Liquid Plug Hole Toilet Cleaner Tool For Home, Office, Garage & Shops (1 x 5 Litre)

My drain was blocked for days, I tried everything even other so called drain unblocker. Nothing worked until I bought this drain unblocker and the blocker was removed.

Works really well. Kitchen drain blocked so I plunged, dissembled u bend etc to no avail. Blockage must have been beyond the ubend in the vertical bit behind the kitchen cabinet, how do I even fix this, beyond my diy skills. Looked online and bought this. Fed it into downpipe via tube, 1 lhr at a time over a few hours and 1ltr overnight. Reassembled u bend and blockage cleared. Used about 1/2 of the 5 ltrs.

As far as I can tell it seems to work, but short of shoving a camera down the waste pipe can't be 100% sure. Not as thick as I thought it would be.

Good product arrived promptly

Used on a kitchen sink, so a u bend then long straight run out through external wall to outside gulley. Problem long straight pipe gradient is too shallow so overtime grease gathers at the bottom of the pipe until you try a liquid sink unblocker then this might move some of the grease further down the pipe until it completely blocks. I hoped that this product has some magical properties which could just dissolve away all blockages, no it hasn’t, i guess that level of caustic ness would be potentially dangerous so instead. Solution to unblock, disassemble the sink u bend to long pipe run connection and pass a stainless steel sink unblocker cable through until you hit the block and push through until it is cleared, then run plenty of hot water through to clean thoroughly. Then routine maintenance every week empty a sink full of hot water through to keep the pipes clean. Or for mild blockages use boiled water and a sink plunger, once flowing pass lots of tap hot water to clean out, but if this doesn’t work, it usually does, disassemble and rod as above. Bleach can be used also of course for hair, so better for bathrooms and is cheaper.

Did not work as much as I thought it would

Works very well and very quickly good price for action and positive impact

This is value for money and worked wonders on my blocked outside drain. I poured it down the drain and you could actually hear it bubbling and just like that the blockage was removed. If ever I have another blocked drain this is the product I will be buying. Well recommended
