Water pressure regulator...

I mount my adjustable water pressure regulator directly to spigot, our water filter is located inside our rig.

X2.
May as well protect everything.

SAME^^^^^
WHEN I use a regulator it goes on spigot then a 'wye' with shutoffs.
Potable hose then filter
Garden hose on other side of 'wye' for general use


And 'WHEN' I use a regulator is just for filling fresh water tank.
After a $6000 repair due to $0.50 fitting breaking and RV getting flooded I no longer stay connected to 'city water'-----use the pump exclusively

Thank you for the info so far.

I put my regulator right at the trailer or camper.
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.

I'd put the pressure regulator in the line before any of my stuff that I didn't want blown up by the high pressure the regulator is supposed to protect you from. This means at the hose bib from which I draw water, before my hose/filter/trailer inlet.

I learned this lesson the hard way. I once ran my white drinking water hose from the hose bib to the regulator, then into my trailer. Turned on the water, looks good, not even a drip, so I go inside to get an icy cold one, and glanced out the window to see water spewing from the bib/hose joint. The pressure was so high it split the hose right next to the fitting.

This lesson came in handy a year or so later, when I camped at a campground that was located on the side of a mountain. They put me in a site at the bottom, where the water pressure, had it been merely 20 psi nominal up at the lodge beside the highway whence the water supply was located, would have been boosted substantially in the course of coming the 300 feet or so DOWN to where I was located. Guy across the way from me split his water hose.

Park Regulator, LONG hose...

IF you use an external filter,, Filter and short hose, Keep filter OUT of sunlight

I put mine on the faucet. I got up one morning and my hose looked like it swallowed a pig.

This is exactly why I do the same thing. I never hook up the hose to the fresh water inlet. I always fill the fresh water tank and pump from there. And .... I've never had problems doing it this way either.

But, for the OP, if you are going to use a regulator, put it on the spigot. Hopefully, if it fails, your garden hose will blow before the pipes in your camper does!
