This is another shout out to Ori and his son Daniel at Galaxy Plumbing. I had a very complicated problem with water hammering, banging and all sorts of pressure problems. They were relentless in figuring out what needed to be done and stuck with the job. My plumbing is like brand new in a house that is 31 years old. I had tried with approximately 15 plumbers before them and none of them could figure it out.
