are there any true hi-flow pressure regulators?

[larry2c]

This would actually be for my stick house hose bib and not for our trailer. Our hose bib in the front of the house is on the street side of the house pressure regulator so it can see water pressure over 100 PSI at times. I love that for blasting the dirt off the vehicles but it also kills my hoses and anything I put on the end of them (sprinkler, foam canon, you get the idea).

I tried a couple of the screw on 40 - 50 PSI regulators I have for camping and none of them has a decent flow rate - even the ones that have "Hi-Flow" stamped on them. Anyone know of a regulator that really does have high flow and gives around 50 to 75 PSI of pressure?

Something like this? https://www.amazon.com/RVGUARD-Press...a-885437404462
If you're looking for a higher pressure for the shower, consider an Oxygenics shower head. It increases the oxygen in the shower and you get a more pressurized experience.

RS sent you exactly what we have too.

It's not cheap, but I got 10+ years out of my last RV Water Filter Store water pressure regulator:

A trailer pressure regulator is designed for a 1/2" hose. You need a 3/4'"one or larger. Likely near $100. 125% greater flow rate likely.

you said 100psi at times, is this 100psi all the time or only shows that if you use one of the gauges on hose bib that shows you max pressure?


Most times this pressure spike is caused by hot water heater. As water heats it expands, but because water will not compress the pressure raises. A simple 2 gallon bladder expansion tank on the cold side of the house will fix

OP explained the hose bib in discussion is hooked up before the regulator.

MY house doesn't even have a pressure regulator. Backflow preventer is inside my house not out at the street.

Yes. This is the one we use on our whole house. The city delivers water to us at 140 psi, to compensate for undersized mains when this neighborhood grew faster than anticipated. Out of the box, this one is set for 75 psi, but it is adjustable. It 3/4" IP threads. You would have to unscrew the hose bibb and place this in-between or make up some IP to Garden Hose (GH) adapters for both sides.

These last about 15 years here before the thin internal diaphragm gets a pinhole.

When I was was in the underground business we used this one. Watts LF25AUB-Z3

Thanks all, I appreciate the suggestions. I could go for the one Reverse_snowbird suggested if I was pretty sure it had a higher flow rate. Not sure I'd be willing to invest $100 or more for one of the actual "house" versions. FWIW, we have the Watts LF25AUB Z3 that services our house and it works fine - but, they don't last forever - we're on our 3rd one in 35+ years.

The one I referenced in Post #7 is only $67.

I mentioned the ~15-year lifetime in that post.

If you install a 1/2” pressure regulator you will not like taking a shower on wash day!

Less than 50% of the flow. Tolerable in a trailer. Not so much in a house.

The one I recommended was 3/4".

All pressure regulators last longer if they have a pre-screen or filter.

Be aware that high flow and low pressure are counter intuitive. To get high flow at low pressure you need larger hose and fittings.

Thanks but this is something I want to attach to the hose bib - so it will only be reducing the pressure for that garden hose. That's why I started out with the little brass ones you get with your RV
