Intelligence, it would seem, is something often lost in the plumbing world. That is not the case however with this Royal Flush company. These guys are truly as good as they come. Our plumber, Matt, was able to solve an ongoing issue that had stumped "the best" that four other companies had to offer. Matt B is a true hero to us and we will sleep much more sound now that we do not have to worry about our water being contaminated.
