Do I have to use water regulator

I never use one. I have been a plumber for over three decades and I have seen pressures up to 400psi on systems more "fragile" than an RV's system. At my last home, my street (and house) pressure was 120psi and I kept the water hooked up and on to my RV all season long. So many people have no idea about plumbing and are just spouting what somebody they think is smarter than them said. You can feel comfortable subjecting your RV to pressures well above the 40-45psi that I so often see posted here.

Take a real shower.

I don't want to insult you but do you think it wise to advise people to ignore the rating imposed by builder of the unit? Maybe it is completely capable of withstanding the pressure you're talking about, but will you stand behind your statements with money to repair the damage if their particular plumbing won't withstand 120 psi because the dealer only installed a part built that was only good to 60 psi? Or they have some fittings that won't leak at 80 psi, but develop a seep/drip/leak at 130 psi? Some of these units are really poorly assembled and may not stand up to very high pressures.

I had the anti-siphon device, a cheap all plastic unit, on my toyhauler pop its top off when subjected to the high pressure of the water at Fishing Bridge in Yellowstone. There was a warning about using pressure regulators because of the high water pressure. I did have one on the water inlet, but hooked up the toilet flush straight to the faucet and it cracked the glue on the anti-siphon unit. Discovered it when I notice water running out the bottom of the toyhauler.
