sneaky_ho 1 Report post Posted February 22, 2013 Hi,My common toilet water basin outlet is chocked. I think the problem is with blocked drain between the wall outlet of the basin and other end to the main water disposal. Most likely need some kind of high pressure water blasting to clear the chocked deposit in the drain. Anyone have good encounter with plumber utilising such technique to clear chocked pipe ? Pls recommend. Share this post Link to post Share on other sites
