Leaky city water inlet - I ordered one off Amazon. It came, I put it in, and then realized old one was marked 50 psi, and new one is 65. Tech curves show 50 actually allows 58 at 100 psi input, and 65 allows 70 at 100 psi input. I wish I had known to order the 50 first, but anyone with real world experience to determine if it is worth swapping lower at this point? Seems like 12 more psi won't matter in real use.
The one I took out was dated 1997, so it went in when the coach was 22 years old, and lasted 24 years...not bad for plastic and rubber piece.

I wouldn’t want to deal with 70 psi pressure in my coach piping. I would put a pressure regulator at the hose bib set for around 40 psi and call it good.

I had my lines blown apart by high city water pressure. In about 2010 I got
a filter/pressure reducer and used that for a season, still hooked up to
city water systems. Finally got tired of fixing plumbing because I was
hooking up to city water, so I solved that issue by improving the potable
system in our coach.put in a new pump and much of the plumbing, and we just
use the potable system. It works well for us.

My coach had a regulated city water inlet on it, I assume from the factory. It developed a leak, so I replaced it with a new one from Applied GMC. I think it was a 40 # rated inlet, but I could be wrong.
