Water regulator question

[tjwoods1]

Camco water filters recommend using a water regulator attachment. My 2015 Bambi Sport specs say that I have a built-in water regulator. That being the case, does that render the Camco regulator unnecessary?

The inboard regulator protects the Airstream, you'll also need one for the hose too!

It's a good idea to use one on the hose anyway. I've had to replace the inlet with the regulator twice in 10 years, it's prone to cracking and leaking so I think keeping the input pressure at 50# is helping with keeping the stress on the internals to a minimum.

The inlet connection is also a water pressure regulator, no need for another.

The campground connection has an anti-reverse flow valve on it, expansion in the hose from the sun and heat of the day will flow into your Airstream. That excessive pressure if any, as well as expansion in the water system from the gas/propane water heater, will be taken by the air bubble in your water heater (that's how they are designed, believe it or not). That air bubble must be maintained or water will leak out the water heater temp/pressure relief valve, may find a weak connection in the plumbing to leak, and may over stress the connection hose or connection.

The hot water heater bubble is frequently lost. We added a backup by simply putting a water pressure accumulator in the cold water plumbing line that goes to our bath sink. Camping World and Amazon has them.
