Camco 40065 RV Water Pressure Regulator with Gauge
Camco 40065 RV Water Pressure Regulator with Gauge — Product description
The Camco 40065 is an adjustable RV water pressure regulator with a built-in gauge, so you can see exactly what a campground hookup is sending into your rig and dial it down before it does any damage. Lead-free polymer body, 3/4 inch hose thread, and a 90 degree design that keeps the hose out of your way at the spigot.
City water hookups at a campground are a gamble. One park runs a gentle, easy pressure, the next one slams your rig with 90 PSI or more, and your RV's plumbing never signed up for that. High pressure is how you end up with a cracked fitting behind a wall, a leaking water heater, or a blown supply line while you're out hiking for the day. The Camco 40065 sits between the campground spigot and your fresh water hose and takes that worry off the table. Turn the knob, watch the gauge, and set your incoming pressure to something your lines, fittings, and water heater can live with all season.
What we like about this one is the gauge. A lot of regulators are set-and-forget pucks that give you no idea what's actually coming through the line. This one shows you the real number right at the hookup. So you can dial it in the moment you connect, and glance at it any time you suspect a park is running hot. The knob is fully adjustable, not a fixed factory preset, which means you're in control of the number instead of trusting a one-size setting that may or may not suit your rig. Newer RV with PEX everywhere? Older trailer with tired fittings? You set it where it needs to be.
The body is a blue polymer, not brass, which keeps the weight down and won't corrode on you over the years. The connection is a standard 3/4 inch garden hose thread, so it mates up to any campground spigot and any RV fresh water hose you already own. Nothing special to buy. The 90 degree design turns the hose downward right at the tap. That's a small thing until you've wrestled a hose that wants to kink straight off a low spigot, and then you really appreciate the angle.
Drinking water safety is handled. The 40065 is lead free, carries CSA low lead content certification, and meets NSF/ANSI 372. So the water coming through it is safe to drink, cook with, and use to fill your fresh tank. If you've got kids along or you top off your tank for boondocking, that certification is worth having.
One honest note. This particular model does not have a built-in check valve. A check valve stops water from flowing backward through the regulator, which some folks want when they run an onboard water pump and a city hookup on the same plumbing. If backflow prevention is on your list, plan to add a separate inline check valve. For the vast majority of RVers who just want to protect their plumbing at the hookup, it's a non-issue, and skipping the check valve keeps the flow strong.
A couple of field tips from folks who've installed plenty of these. Wrap the threads with plumber's tape before you snug it down. Polymer threads seal fine on their own, but a wrap of tape keeps them from weeping under pressure and saves you a puddle at the connection. And when you're winterizing or storing the rig for the cold months, pull the regulator off the hose and store it inside. Gauges don't love a hard freeze, and the needle can stick if the unit sits out through a deep winter. Treat it right and it'll ride along with you season after season.
For most travel trailers, fifth wheels, and motorhomes, this is exactly the kind of gear that should live on your fresh water hose permanently. It's cheap insurance against a burst line or a blown fitting when you're parked a thousand miles from home. Screw it on at every hookup, set the gauge, and you can stop thinking about water pressure for good.

Frequently asked questions
What does the Camco 40065 do for my RV?
It regulates the water pressure coming from a campground or city hookup before it reaches your RV plumbing. High pressure can crack fittings, split supply lines, and damage your water heater. The 40065 lets you set a safe incoming pressure and see it on the gauge.
Is the 40065 adjustable?
Yes. It has an adjustable knob, so you set the outgoing pressure yourself rather than relying on a fixed factory preset. Turn the knob, watch the gauge, and set it where your rig is comfortable.
Does it have a pressure gauge?
It does. The built-in gauge shows you the real pressure right at the hookup, so you always know what's coming into your plumbing and can adjust on the spot.
What size is the hose fitting?
Standard 3/4 inch garden hose thread on both ends. It connects to any campground spigot and to any RV fresh water hose you already own.
Does it include a check valve?
No. This model does not have a built-in check valve. If you need backflow prevention, for example when running an onboard pump and a city hookup together, add a separate inline check valve.
Is the water safe to drink through it?
Yes. The 40065 is lead free, carries CSA low lead content certification, and meets NSF/ANSI 372. It's safe for drinking, cooking, and filling your fresh water tank.
What is it made of?
A blue polymer body rather than brass. That keeps the weight down and resists corrosion over years of outdoor use.
Why is it shaped at 90 degrees?
The 90 degree design turns the hose downward at the spigot, which cuts down on kinking when the tap sits low to the ground. It's a small design touch that makes hookups easier.
How do I keep the fittings from leaking?
Wrap the threads with plumber's tape before tightening. Polymer threads seal well, but a wrap of tape stops any weeping under pressure and keeps the connection dry.
Can I leave it on through winter storage?
We'd pull it off and store it inside. Gauges don't handle a hard freeze well, and the needle can stick if the unit sits out through a cold winter. Remove it when you winterize and it'll last for years.
