water pressure regulator

Hi guys,
we are getting ready to set the plumbing in the Avion and one of the thing that we will like to replace is the Water Pressure Regulator.
Looking for some of them at HD and Lowes and they all look pretty similar.
So just any pre-set to 45psi with a back flow valve will do it? any suggestions will be great to help in the decision process.

You could just install an Airstream water connection and have a clean installation. Item 14765 on this site

well this is the original design that uses the same door for water city connection and fresh water tank fill up, so I really don't want to make a new whole in the trailer and really don't trust the little plastic ones

Keep one thing in mind. This thing, sold as a pressure regulator, will do NOTHING.

Camco 40055 Brass Water Pressure Regulator - Walmart.com

A regulator has to have a means of stopping flow in order to control pressure once the set pressure is reached. This thing are an open bore and can not control pressure. At best they might control flow volume in an full flow request but I doubt that would even work.

What you have pictured is a standard Watts Pressure Regulator available at any plumbing supply house. Generally they are adjustable as noted by the screw on the top.

True and that one says it has a range of 25-75psi they are normally preset to 45psi. I can't tell from the picture if it is for 1/2" or 3/4" pipe just get one with the same size fittings, unless it's 1/2" and you want to get 3/4" and adapt it down(this would help eliminate a flow restriction since a regulator can't flow as well as a hollow pipe).

Do you know that the regulator you have is bad. I don't trust any of them unless you have a gage down stream to tell you if it is working.

I've used this one a few times. If you are replacing all the plumbing with PEX it is a good fit. Your old regulator may be good, but like Perry says, you'd have to check it with a gauge to be certain. They do sell regulators with a gauge attached.

Hi Guys
thanks for all the inputs.
We are not aware of the regulator condition, BTW any way to test it?
we will be re-doing everything on pex so we are thinking that replacing the existing as an extra insurance.
We were thinking on getting one with a gauge and wondering about the chance to have a "remote gauge" so the pressure can be easily monitored.

How about this one, can the gauge be re-located for monitoring purposes?
Or maybe we should ask if the gauge indicates the incoming or the outgoing pressure into the system?

A remote gauge is fairly easy just run a line to where you want it put a fitting on the end for the gauge to screw into. It is a little harder setting it up for winterizing need to have a T-fitting for the gauge and a valve or leading to a faucet ect... so that line can be drained, blown out and/or filled with anti-freeze.

Well the gage is on the outlet so it reads the regulated pressure not the supply pressure.

Where was the source for the pressure regulator with gage with hose fittings?
