We all know to use a water pressure regulator on our campers, but was just wondering, at what pressure are TT build to withstand ?

I think you'll find that the answer varies; some people have said particular makes/models are supposed to be able to handle over 100 psi. But given the potential from water leak damage, go with the regulator. It's not worth the risk.

i respectfully suggest that you really need to read your owner's manual. You'll be surprised at all the great info you'll find in there.

From new, mine leaked at zero pressure, so that is my answer.

I bought a brass Valterra high flow regulator at 55 psi and the high flow is alot nicer than the junky white plastic one I had before. My owners manual said I had a built in regulator, but either it failed or it's not there. I had a supply line to the kitchen sink seperate. Presure at the spigot >100psi. Owners manual, Schmowners manual!

Don't trust those cheap regulators. They are flow restrictors but still allow your system to see full pressure when water isn't flowing. Once I installed an accumulator (after the 12V pump to smooth out flow), I saw 100psi at the faucet for the first second of use.

For me, it's not so much how much pressure it can handle, but the effects of bouncing down the road and how high(er) pressures in the future might play into the whole scheme of things.

This is not true. I always checked for leaks in water systems with air.I would grab up the first cheap regulator i found. Pressurize the system and check the system for leaks. The system would be pressurized for 15 to 20 minutes and the pressure stayed the same.

Both my TT's have residential grade PEX lines throughout, which is rated to 150 psi or so (IIRC). However, they both have plastic fittings such as elbows and valves which do not sport any kind of pressure rating labels as far as I can tell. In fact, the smaller unit has plastic faucets and one of those (the kitchen) blew the curved neck right off, even with water pressure below 50 psi.
I'd recommend taking a look at your water pump to see what pressure it is rated at and set a pressure regulator to that value for your city water inlet.

I use a cheap water regulator with no issues. I believe mine is set to 40 psi.

Most people worry about having high pressure but what you what is high volume. Volume flow of 2-1/2 to 3 gallons per minute will give a "household" shower feel. The low cost regulators are good for 2 gpm when new but quickly drop to 1 gpm. In line hose filters are only good for 1-2 gpm.

For the good of your RV plumbing, 45-55 psi is enough. Remove the other flow restrictions to get that good shower feeling. Use high volume pressure regulators and household water filters.
