Water pressure regulator...

When the hose sits in the sun the pressure increases. The hotter the hose, the higher the pressure, so the pressure in the RV goes up if the regulator is at the spigot. If the pressure goes up in the hose with the regulator right at the RV and the hose breaks no big deal , just buy another hose, or a mending kit. There has been no high pressure in the RV.

The pressure increase in the hose from sitting in the sun is negligible, only a lb or two at most; rather, the hose gets soft and expands, which actually relieves that pressure increase. And if the hose breaks, there has been no high pressure in the RV, regardless of which end the regulator was installed on. In fact, the hose is more likely to break if it is subjected to the un-regulated campground pressure.

I put my regulator downline (at the trailer) for several reasons:
1. Filter prevents clogging of the regulator
2. Pressure drop through the hose is avoided
3. If the regulator fails, the hose will not save you.

I understand #1, but #2 and #3 make no sense.
#2 There is very little pressure drop through a 25' 3/4" hose; about 0.5psi, certainly not enough to have any real effect.
#3 If the regulator fails, the hose will not save you regardless of which end has the regulator on it.


Personally, I use the regulator at the faucet; that way EVERYTHING is protected; I see absolutely no downside to that. YMMV.
