I'll pick up one of those adjustable regulators if I need to. It was impossible for us to to a shower.
1. This has not been my experience. Other than the natural 'resistance' due to the plumbing there is no restriction downstream of the city water inlet other than possible blockage at the service points.
2. I did a qucik Google of this and it seems that around 40 - 50 psi is the alleged number. However the rvwaterfilterstore.com
suggests that RV plumbing is rated at 125 psi but 65 psi is good enough. Don't know the source of their information and I don't trust 125 psi either. I use 45psi on my Watts regulator.
I am a believer in the Watts regulators which regulate the pressure without significant reduction in flowrate. I have the Adjustable 263A Regulator (similar to the 263A-LF) on the same page in the link above (bought from this seller). Now has some rust on the gauge but still works like a champ after maybe 4 - 5 years.
