Pay attention to your water bills! I didn't and paid the price (literally). I didn't realize that both my toilets had leaks in the tanks. Which means wasted water--24 hours a day. I finally caught the problem (18 long months after it had started) and called Roy at Mayday Drain Services to come and have a look. A friend recommended him and Roy is highly rated here on Homestars. The fact that Roy showed up at all makes him better (in my experience) than most of the contractors out there. Even better, Roy showed up with a good sense of humour and promptly identified the problem (which was much less drastic than I had imagined). Roy is a drain specialist, but he did a great job in attending to my plumbing issue. Everything was sorted out quickly and efficiently. If only I'd called Roy a year and a half ago! So I would definitely recommend Mayday Drain Services.
