I use the Watts pressure regulator set at 60 and the Oxygenics shower head. More than adaquate.
Watts Pressure Regulator
Much cheaper at
RVwaterfilterstore.com - $64.95 Excellent service from this place too. (Amazon can be a ripoff sometimes.)
An exterior mounted inline "regulator" is not really a regulator and is simply a flow restrictor. They only have a very small dia. hole inside them, nothing else. It will reduce pressure when there is a flow, but when there is zero flow, the pressure will equalize on both sides of it and you can end up with excessive pressure in your system.
A real regulator is a much better choice like the Watts H560 mentioned above. Even better for a few more $$ is the Watts 263A with about twice the flow rate of the H560 and is what we have. I have ours set to 60 psi.
You are better off always using a regulator. The pressure in a CG can vary a lot from night to day and can go up quite a bit during the night. I have a tell-tale gauge ahead of our regulator and the highest pressure it recorded for the season was 100 psi and I have no idea when or where. I've read some saying pressure can reach close to 200 psi. Best to use good protection 100% of the time.
