"We ended up going with a tankless solution that was installed the next day. Everything was completed in a single day (including removal of the old tank). I can't speak highly enough of the guys who were here, they were all professional and courteous. I would definitely recommend Water Works and hire them again (so much so that I signed a service contract with them for the new unit)"
