I have always used the non adjustable and was thinking of changing to an adjustable, just so i would know the pressure. After reading through the comments, I now think i will just stay with the non adjustable. Thanks for the topic, it has enlightened my thoughts on pressure regulators.

Seriously I always had the non-adjustable ones for years but a few years a go I bought an adjustable. I have never had to adjust it after the first time. Have to be more careful not to break it too. Not sure it's really necessary, I think I would have been fine with a non-adjustable. That's my .02 anyway.

Lol! Good one! And good advice! I started out with an adjustable about 8-9 years ago then I decided it wasn’t worth stressing over getting exact pressure I wanted! I’m fine with that in-line cheap-O one, no issues whatsoever!

I have never seen a regulator that is not adjustable. There are some that say they are adjusted at fifty pounds, but if you look at it real close they can still be regulated. The only ones I have ever used are all brass and I have it where it attaches right at the faucet, then the hose follows.

I have always found that a 50-55 psi fixed pressure regulator is all you need. I carried one spare and had two regulators fail over the years. Not bad and not very expensive. I also carry an inexpensive water pressure gauge (cheap Lowe's Rain Gauge type with a faucet connector) just because I like to know what a campground is putting out, but it isn't necessary to have one of those.

The problems with adjustable pressure regulators are (1) they fail, (2) they are expensive, (3) they are bulky, (4) people steal them, (5) they aren't all that accurate, and (6), you don't need an adjustable regulator. Save your money.

I started out with a fixed, non-adjustable and found the water pressure in the rig too low to suit my needs. It did not have a gauge, so I had no idea what pressure it was regulating to. I bought an adjustable regulator with a gauge on Amazon and can adjust it to 50psi which I find a good pressure. So, my preference is for an adjustable regulator with a gauge.

No need to adjust, but it's nice to "see" the pressure you are getting. I've always used the fixed 55psi regulator, which takes care of the guess work ... less to worry about.

I find that the non adjustable pressure regulators have to low pressure (40-45). I prefer to run at 50-55 so the adjustable allows me to do that.

I like the adjustable ones because I have noticed at some parks, we have very low pressure with a static regulator but when I moved to an adjustable one, I am able to increase the pressure in the coach. Don't ask me why but hey it works for me.

I started with plastic. Then I went brass adjustable. Then I went to brass fixed. I'm back to plastic. They all do their job. They're all going to end up in the trash anyway, no reason to make your trash more expensive than it already is. I keep a spare or two in the trailer.

I also chose to buy a Watts adjustable regulator because it worked as advertised. I have used this for about 5 years now & I am thinking it might be time to rebuild it. In the past I tried several fixed water pressure regulators that said they would give me 40 or 45 psi but when I checked with a pressure gauge I saw that I was getting somewhat less from each of them making for a poor shower each morning.

I agree with Old-Biscuit. I just read something about water hammer that could occur after water was shut off for a repair and then turned back on. The author claimed that no pressure regulator would stop the water hammer pressure. The recommendation was to fill the holding tank and disconnect. Use your water pump, it will keep it working better.

If all I want is this pressure, what would be the benefit of an adjustable regulator? Some may say how do you know that you are actually getting the 50-55psi with a non-adjustable regulator. Well, you got me there, but other than that, what's the benefit/reason for adjustable pressure regulator.
Thanks

I use non-adjustable. If water pressure is low/poor, I run my water pump.

Safe travels

Just out of curiosity I bought a water pressure with a second needle that indicates the maximum pressure since the last reset. I've had it go as high as 110psi. Make sure you use a regulator of some kind. I use an adjustable just because I like to control things.
However, I have found, as time goes on I hook up the plumbing less and less. I plug in right away, and lately only connect the water hose to fill up, or the stinky slinky to empty out, unless I know we're goin to use the shower that day.

Been using the same adjustable regulator with a gauge since we started camping in 2019. No problems, never been stolen. Only need to adjust it once in a while.

For those of you who have fixed regulators and want a pressure gauge, there are lots of them on Amazon. Just make or buy a T and keep it attached to the output of your regulator.
