Water Pressure limits?

I received an add from RVupgrades advertising a Remco Aquajet water pump that puts out 60psi at 3gpm. While it would be nice to have that much pressure for some uses, I am wondering how the typical RV plumbing would handle the pressure. I have a pressure regulator on my input hose set at 40psi to protect from high water pressure you may encounter at some parks. I would hate to have water lines popping off under the floorboards. Has anyone had any experience running higher pressure and are most coaches water systems designed for this?

I am going with that the water pump itself is not going to rupture you internal fresh water plumbing lines. I have a 5.7GPM Shure-Flo that delivers 65 PSI. It has never entered my mind that the PEX system on our motorhome would be compromised. I have been using the pump for 8 years and so far so good.

I will always use a regulator if the water pressure is sufficient to push a stream of water across the street! Better safe than sorry but I don't always use a pressure regulator.

I think PEX is rated for 100 psi (for the tubing) and the connections should be able to handle that much without a problem. I use a regulator with a 50-75 psi range of capability.

I agree with Doc, PEX is rated @ 100psi. I've heard others say their mfgr says not to exceed 80. Where we are in Az right now, the psi is over 100. Since I have a '99, I set my regulator at 60psi to be safe. Plenty of pressure so no need to test the limits.

Having been a plumber I can tell you that all manufactures of faucets, residential toilets etc. like to have 55 psi MAX. I carry a simple pressure gauge and always check the pressure at the standpipe. I have seen 100 psi in campgrounds. Also keep in mind that most water pressure will creep up at times of low use (late nite) I went with a residential main line pressure reducing valve that has a gauge port on the body. These are easily adjustable and with the gauge you see exactly the incoming pressure. I also have before my hose because hoses are not rated for more than 55 psi. I did spray the bronze valve flat black to deter theft. Never had much luck with the cheapo walmart reducing valves.

I bought a regulator after reading about them on this site, never new there was such a instrument. I use it faithfully just because the pluming is 32 years old. So far so good best 50 bucks I have spent on the old gal. Again better safe than sorry. JMO
