Pressure Regulator

[pjtaia]

How important is a separate water pressure regulator where the hose connects to the Airstream? There is an internal regulator, right?

I want the best pressure possible, but I don't want the risk of blowing out the plumbning system. If I check the internal regulator and it is good, am I safe without a separate regulator?

Thanks for your help!

For the minimal cost of external regulator, (10 dollars or less), you are better safe than sorry.

I think that would depend on where your internal regulator is located. If it is six or eight feet from the from the city water hookup it leaves that much plumbing exposed to potential high pressure.

The problem is really if you have a source with high pressure. I think the factory relief valve on mine will lift at 75 psi. Well I found out it works just fine when I hooked up at my house for the first time! It turns out that the "city water" supply at home is around 100 psi. I simply bought one of the hose end regulators (with the gauge on it for curiosity purposes) and it regulates it right down to about 60 psi. Never had a problem since. Cheers!

Here is the reason you should get one of the screw on regulators and use it on the campground faucet.

When the last person has used their shower at the local campdround and their water system finally catches up the pressure can exceed the bursting pressure of your water hose. Leading to a very soggy site as well as no water in the AM for your morning shower. The reduction in pressure to 45 PSI or so will not be noticable and then you will be protected from any excessive pressure. As the hook up hoses age and get baked in the sun they will develop weak spots and that is where they will fail.
