Plumbing requires occasional maintenance, repairs, or just updating the hardware. Sometimes these repairs are hidden in the walls and usually when it is bathroom plumbing that needs attention it is behind tiles walls. This makes for very tricky situation and a highly skilled and experienced plumber is best for these types of situations. If you don’t hire the right guy you might have to hire a tile guy after to fix the mess that the plumber left behind. In this case we had to replace the shower tub valve that was located behind the tile. We replaced the valve and left the tile unharmed.
