The house is three years old, on a slab in Fl and it just started. I have been told to put on a reduce pressure regulator and water hammer arrestors. I would need 5 arrestors in the bathroom or how could I find out which pipe is the culprit. Someone also mentioned an expansion device on the water tank. What is the best thing to do? I am handy. Thanks

It is extremely unlikley that you have a pressure problem in Florida that would require you to install water hammer arrestors or a pressure regulator at all.

Pressure regulators and arrestors are usually only required in regions of naturally high water pressure, and these regions are usually only found in mountainous areas of the country where water reservoirs occur at elevations hundreds if not thousands of feet above your home.

Since the highest elevation in Florida above the end user's home is but a mere 100 feet or so above the spigot, the highest pressure normally attained in Florida is but about 6-lbs PSI, or a completely normal pressure for public or private water service.

Depending upon what 'type' noise you have experienced, it sounds a lot more like you have some pipe expansion problems possibly associated with clamps too tight or pipes going thru holes in wooden framing members of your house that are too small for the pipes.

Not a water arrestor nor a pressure reducer problem at all in my humble opinion.

Thanks for the reply. The noise is like a hum or moan.I have been trying different things to locate the pipe making noise. I cut back on the water coming in, main water line and the cold pipe under the bathroom sink you can feel it vibrate and got louder when the toilet is done filling up. I opened the main valve a little more, flushed the toilet and after tank filled less humming.We get a slight humming in the the bathroom, not all the time, when the kitchen water is shut off quickly. We can shut it off quickly 3-4 times and it would make noise once. Does this still sound like it's pipes expanding in the frame or tight clamps?

Thanks for reply. The noise is like a hum or moan. I cut back on the main line water and after the toilet filled up in the bathroom the maon /humming was louder on the cold line under the sink and I felt vibration in the line. I opened the main line more and the sound was less. Any new suggestions
