    I'm guessing you mean the same thing as a pressure regulator for the city water going into the unit? If so, I'm sure its a yes. I called 2 days ago to ask the question about my 369RL. Grand Design said yes you need to protect the system from spikes in water pressure. Bought one on amazon for about $8-10.

    Does anyone know what the water system lines in the Reflection have been pressure tested to?

    But for a pressure regulator, throw away those cheap 8-20 dollar units. They reduce pressure, but also reduce flow to a fraction of what you desire. Spend a few dollars more, get a pressure regulator that provides a decent flow rate, minimum of 2-2.5 gallons per minute (what your 12v pump will put out), and you can actually adjust the pressure on. Mine cost me about $45, 10 years ago, but well worth it. It came with a gage that I could see what pressure I was setting, but the gage stopped working long ago. I just haven't replaced the gage due to having set 50PSI of pressure then, and have not changed it since. I do have another gage that I put on the spicket to see what pressure is prior to hooking up hoses. If it is 50 PSI or under, I just leave the regulator off. I have been in some campgrounds that have over 100 PSI of pressure. You will definitely need a regulator there. Most of those also state somewhere on their info packets that the pressure is that high.

    I've used a pressure regulator in the past and found that there's less pressure than if is was running the 12V pump. In that case I ditch the regulator and adjust the faucet to have about the same pressure as with the 12V pump. I've never found many campgrounds that have much pressure due to their distribution system.

    The city connection on our is stamped as 80 psi max though I wouldn't ever want to run it there. When you don't have a sewer hook-up as with most our camping, the higher pressure just helps to fill the tank faster.

    I do a little test (some might consider this a little silly) by hooking up one end of the hose to the campground supply and turning it on full blast. If the water shoots out of the hose about 5-6 feet, which is what it does at home, I figure I'm good. I know the house pressure is 45-55 so I use that as a gauge. If it shoots out much further than that, the regulator gets installed.

    Along with the water pressure regulator, don't forget to add an in-line water filter. You never know what kind of particles might be in the camp ground water supply.

    If using inline water filter, be sure to put your pressure regulator on prior to connecting the filter. Reason is high pressure can blow the charcoal pieces out of the filter throughout your water system, clogging various things. My son-in-law had this happen to him, all his faucet screens had to be cleaned due to being clogged by charcoal. He put his filter on first, then the regulator, only did that once he said.
