I had a clog, loud running water noises and prolonged post flush struggles coming from the toilet this morning. Given that it's the only toilet in the condo, I called GTA plumbing services and they sent someone out within 2 hours - not to mention that we're in a pandemic.
My technician was EDRISS. He wore a N95 mask and gloves. He was extremely helpful and definitely knew what he was doing. He unclogged the toilet and he diagnosed the struggling flush that the toilet was making. He removed the flapper and showed me that it was eroded. He quickly changed then heard further noises coming out of the tank. After a quick check, he showed me that the fill valve was leaking. He had everything handy and he quickly changed that too. After quadruple checking, the toilet flushes perfectly with no post flushing noises! He cleaned everything up and it works like new again! It costed $250+ tax for parts and labour, which I think is extremely reasonable giving the circumstances of these times. The 1 year warranty puts me at ease. Thank you Edriss!
