We continually have great experiences with Paradigm Plumbing Services. They come in and identify the problem, then they get the parts to fix the problem--and everything works. Not too long ago, the water filter was changed by them. It had a leak, so they had to replace one of the filtration units. They did that and replaced a toilet. Their technician also did us a favor and turned off our water for the sprinkling system outside, just to avoid freezing during the wintertime.
