Adjustable water pressure regulator
Those of you with an adjustable water pressure regulator, what pressure do you set? I hear the large shower head in the newer DS requires more pressure. I have one on order and am trying to decide if I want to mount it inside. I like having it mounted in the wet bay but I m concerned about the hose. Has anyone had their hose or any fittings damaged by high pressure?

Not sure how high you'd like to set it.....I have one and it is at the water bib hookup...so covers the hose as well.....I set ours at 50 lbs
I read on here that the Oasis people recommend no more than 45 to 50 lbs on the regulator ...anymore not good for the Oasis pumps....C

50 lbs gives good pressure and won't damage anything. I mount it on the water softener intake.

I have the adjustable Watts regulator and it is set at 50 psi. Seems to work very well with the current coach; we'll have to re-evaluate with the 2018 MADP when we get it in June.
As has been discussed in other recent threads, "flow" is every bit as important as "pressure." Be sure that the regulator you use is rated for high flow. Most of the inexpensive ones are not.
A very good alternative, though not adjustable, is the Fairview 55 unit available from the RV Water Filter Store ( https://www.rvwaterfilterstore.com/Fixed.htm). It is preset at 55 psi (which should be fine for the Oasis system), has very good flow and costs less than $30.

Same one I use except that mine is the stainless steel version. Excellent units.

I can address the shower issue, it’s pretty poor in the 18 DS. After taking the square head apart, I have concluded that it is the design of the shower arm and the shower head. Poor flow and poor pressure. I did replace the shower head with a Price Pfister unit with marginal improvement. I have a whole house adjustable regulator set at 55. It is mounted in the wet bay. The incoming hose on the reel is rated at 150, not too worried about that.

I've had mine set at 65 psi on my last two coaches for the last 14 years. As stated, the water reel hose is rated at 150 psi, so I mounted mine in the wet bay. I also added a splitter so that the water that runs to the black tank wash, doesn't first run through the water filter.

With the small-diameter braided hose in the system, I would think your flow would be seriously affected. Have you experienced any issues with it in the line?

We love the new shower head in our 18 DS.
Over the years I have found that the pressure in many RV parks is not adequate for my satisfaction. I have the Watts pressure regulator. The regulator on prevents high pressure. It does not boost pressure.
I keep my water tank full and always use my water pump. In doing this I have consistent pressure.
