Water pressure at my home connection

A few weeks ago I had a conversation with an American colleague regarding the maximum water pressure at home connections. He was amazed to hear that the water pressure at my house is about 9 bars. To show him I was not mistaken I connected a pressure gauge in my garden and took a few pictures:

According to the guide line the maximum pressure should not exceed about 60 or 65 meters (and that is also very high!). When we bought the house, a few years back, I installed a pressure reducing device and set it to 35 meters (I get no complaints from my girls).

A block down the hill from my house the city installed about two years ago a set of pressure reducing valves. During the construction I took the following (bad) pictures:

    Hi, I find this very interesting, since I’m living in a house that has the same problem now. The pressure can get very high sometimes and that causes leaks in the water pipes. I’ve had to solve that issue many times over the last 2-3 years. And we decided to install that valve. The supplier told us to also install a filter to protect the valve, which I did. I’m wondering if you did as well.
