Sorry guys, you could argue whatever, but while you were doing that i just improvised a new solution to unblocking practically anything, here is how:
1. Get a 2l bottle of Coca Cola, the brand is important and must be reguLAR COKE, do not get diet one.
2. improvise a cap for a pipe or a cover for your wc bowl, such that it will fit air tight when needed, and keep it ready nearby.
3. then Pour 2L bottle of Coca cola into your blocked drain pipe, or your wc pan but save a glass full of this for later on you will need and i will tell you for why
4. get the cover ready to fit very very quickly.
5. Did I say you also need some Mentos, so when you go and buy Coca cola get some Mentos too.
6. drop these in and quickly cover the pan or the pipe end with the cap, for the pan you will also need to put all your weight on it.
7. in the next few seconds there will be a huge woosh! it will either clear your blockage or you will be pushed through your roof!
8. When doing the WC Pan, ensure that your cistren cover is held down with weights, as back pressure can get into it through the pan rim and into the cistren tank and blow the cover off.
If blockage is not cleared, go back to shop and buy 2 bottle s of coca cola and more Mentos, and repeat again.
Good luck, hopefully this new latest technique will render all existing drain clearing expensive equipment good for a scrap heap,
9. Finally when the blockage is cleared, take that glass of Coca Cola I asked you to save, nothing is more refreshing than a glass of chilled Coca cola after
using a smashing technique clearing a blocked drain !
