Water Piping Noise

Hello:

I replace my city water service piping to the house from half inch to three quarter inch. Since then, every time if the second floor kitchen and washroom faucets were to shut off, there would be banging behind the walls (water pipes).

I measured the water pressure in the basement with a water gauge (range to 60 psi). It was way over the limit.

I spoke to the sales associate in home depot. He advised to install a couple "water hammer arrester". But the water hammering did not go away.

Is the water pressure too high?

Should I install a water pressure regulator?

What should be a reasonable psi such that the second floor would have a good shower even water is been used on the main? ( Poor water pressure to the second floor was the reason that I increased the service pipe.)

Any advice is greatly appreciated. Thank you.

60 psi is a good psi...
There are a lot of variables.
What material pipe is it?

Need more info.....

The system is all 1/2 inch copper with 3/4 inch coming into the house.

My first trial with the water hammer arrester was the second floor kitchen faucet. I installed two, one for the cold pipe and one for the hot. These were installed to the elbow valve (3/8 inch), one end to the valve and the other reconnect to the flexi tube to the faucet. See picture link;

660-TR1 - Sioux Chief 660-TR1 - Mini-Rester Water Hammer Arrestor - 3/8" O.D. Compression x 3/8" O.D. Female Compression Tee

The faucet is a moen single handle; see link

The psi is over 60. My gauge measured only to a max of 60. Maybe I need to reduce it?

You need to get a new gauge that will read actual psi of the home. Then we can move forward. Max psi is 80psi.

Your house being all 1/2 you lose volume. Meaning when multiple fixtures are on you will notice a decrease in water flow.
