Water pressure regulators

When we purchased our trailer, we also picked up a water pressure reducer.

After reading on these forums, we now want to get a real regulator. The ones that were recommended were pretty expensive ($300-$500 range). This seems like a lot of money. Is there any reason one like this would not work?

https://www.amazon.com/dp/B07171VDQR...pa_dk_detail_1

It's only around $35. I could even purchase 2 so I have a spare.

Thanks,

Purchased one of these. Looks like the same one under a different name. Works great.

Mark, that is EXACTLY what you need. Absolutely no need to go any further!

This is the regulator I bought in 2016 (when my previous one was crushed when I ran over it). https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

Today, on Amazon, it's about $45. While I can't confirm that the one in the link you posted is/is not the same quality (it may be even better) I can say that the one I bought has worked flawlessly for the past 4 seasons and still looks/works like new.

The one in your link may be the same with a different branding. If so, it's a good buy at $35. On the other hand, if it has "less expensive internal parts" it may not be. I can't comment on the reliability of that regulator, but can on the one I bought. I'd buy mine again if I needed another.

That is the unit I've been using for 2 seasons with no issues. It is definitely much better than the cheap "pressure reducers".

Yup.... been using the $35.00 one for years! You will only need one.... no sense dragging around the extra weight!

We bought a Camco regulator from Walmart for around $35. They're not a stock item so you have to "click n collect". So far (1 season) it seems to be working ok.

looks like the one we got.

I don't trust those ones without a gauge.

I have the same one John linked to above and can testify it is a good regulator and all you need. Can't say I have ever even seen one $300+, let alone that be the recommended one. The only RV accessories I have seen that pricey are voltage regulators for the electrical, not water regulators.

A surge protector/ems is highly recommended as well as one the the above mentioned water regulators.

Good information from all! Let me ask this, what is the recommended water pressure for these Keystone rigs? We have an "in line " regulator set at 50 psi. Appreciate your input.

Most non-adjustable regulators are set at 40-45 psi. Mine is adjustable and I keep it at 45 psi

That is the type I use. Works better than the reducers.

I have used a pressure regulator like this one:
https://www.lowes.com/pd/Watts-Press...ulator/3309168
Plumb it in permanently (if you have room) and you will never have to think about the problem of water pressure as long as you own your RV. I have used one of these for about 40 years on several trailers and have never had a problem.

I purchased a water regulator about 5 years ago (on Amazon) and it's still working. It's still less than $30.

(Search Amazon for: Signstek Water Pressure Regulator)

I kind of cheated a bit in how I set up the regulator and how I reduce the pressure comming into our RV.
Many of the parks we stay at have high water pressure (much more than 65psi).

I like sufficient pressure in our RV for our showers and other uses so I do the following: I attached the regulator directly to the RV's water inlet and have it set at 65psi.

I connect two 50-foot high-pressure hoses together that connect directly to the campground's water spigot.
The 100-foot length that the water has to travel through reduces the pressure somewhat.
The hose then connects to my filter unit that has 3 water filters - 2 of which have a 1-micron rating
(which also reduces the pressure). At our home RV park, the hose from the filters attach to our softwater unit which is then attached to the pressure regulator. At other campgrounds, the hose from the filters are attached to the pressure regulator.

Also, years ago, I replaced our showerheads with the following:

https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

They cost less than $8 and give nice strong showers even in low water pressure times. They worked so great, I put them in our house, also.

I don't know if this is the right method to set the regulator, but it's what I did.
The water pump in our Outback has a sticker that says the pump produces 2.4 Bar. I think the number is correct, but I can't verify that at the moment. I looked up the conversion in PSI and I set our regulator for a bit more than that.
The water pressure in the shower when we're on mains water is a bit whimpy, but sufficient to have a shower with.
I set the pressure as I did for two reasons
1) To reduce the likelihood of causing leaks at the joints in our plumbing, especially those that aren't easy or possible to see and check.
2) To prevent excess inlet pressure from jamming the non return valve in the pump itself. We had this happen before we got a regulator.

We have used this regulator for years without issues. Don't buy two, you won't need a spare as this will last for many years. I set ours at 65psi. Most parks we stay at are less then that already. IMHO the plumbing in newer trailers with pex tubing is much stronger than older trailers with thin plastic tubes. I have tested ours at nearly 100psi w/o any leaks but that much pressure is unnecessary. Shower is where you need the pressure and 55-65 should be plenty.

Earlier I posted that I keep mine at 45 psi. I've been camping a long time and this is the number that was recommended a long time ago and I haven't really thought much about it for years. Perhaps time to re-evaluate. The plumbing systems have improved considerably. And now, with PEX being used, which is the same as in my house, it would stand to reason that higher pressures can safely be used. The main difference between my 5er and my house is the added stress of bouncing the plumbing down the road.

Keystone is quite silent on the matter. The owners manual recommends the use of a regulator but makes no statements as to pressure. It only says to keep an eye on it for leaks...not much help.

Any pressure system is only as good as it's weakest point. I don't know where that is in my rig. Is PEX used throughout? All fittings and joints?

Since it's not likely that we will get any definitive help from Keystone on the matter it becomes an experience/common sense thing. I've seen other online conversations that would support the notion that 60-65 psi is a safe range for newer RV's. No doubt the PEX will easily handle that pressure. I wouldn't mind a little better water pressure, especially in the shower so I'm inclined to give it a try and then do what Keystone says...keep an eye on it.

You're correct in stating that the PEX used in modern trailers is stronger than the PVC or ABS tubing used in older trailers. BUT: remember that the fittings are still PVC/ABS and just as weak as they were "years ago". Towing a modern trailer over the "rough roads" we all face these days, it's not uncommon to "twist and shake" the elbows, Tee and reducer fittings, causing them to either leak or weaken from being flexed. Most owners find that 40-50 PSI is enough pressure to have reasonable "shower performance" while still protecting the plumbing from excessive pressure. Of course, this is "just my opinion" and not a requirement for anyone else to follow.
