Water filter first ?? Then Regulator ?

[Funseeker Mike]

Would it be OK to run the water through the filter first, then add the regulator, then the hose to the rig? The reason I am asking is, wouldn't the filter reduce the flow a bit?

Most regulators are set for 45 PSI-ish. More than enough to get thru your filter.

You'll not notice the difference unless you've got a bad filter or you're trying to flow 20 gallons a minute. Your sink aerator probably limits you to 1.5 GPM.

Don't sweat it unless you're somewhere with really really low water pressure.

What pressure is your filter rated for? Some places have pretty high water pressures and water hammer can be a beast as well on some municipal systems.

No way IMO. I use a watts regulator with a pressure guage thats upstream of the filter. I also place a "Y" on the hose with a water pressure guage that has a needle indicating the maximum pressure. You reset it by turning a know in the center face of the guage. I've seen water pressures exceed 100 psi in some CGs. There's no way I'd subject the filter or the filter housing to those pressures.

If your filter is noticeably reducing the water pressure or flow it's time to replace it. I don't like the blue in-line disposable water filters. I use a 10" canister filter with replacement filter cartridges. They provide more media area for filtration while reducing restrictions .

Regulator FIRST. And not a cheapo plastic/metal one piece. Get a real one:

My setup is hydrant - hose - whole house sediment filter - regulator - hose - RV.

The sediment filter protects the regulator. One little piece of grit and the regulator no longer regulates. I've rebuilt many huge regulators that failed from debris getting inside, the little ones used on RVs are disposable.

We use our Watts regulator, connected to a high pressure stainless steel mesh flex hose off of the hose bib, then the filter. At least the Camco filters are max rated to 60 psi, and I wouldn't think pressure over 60 psi would be good for any other style of filter.

I don't use a pressure regulator as I always fill my fresh water tank and use water from there. However, in my earlier days of RV ownership, I did use a water pressure regulator and attached it directly to the campground shore water spigot. Why? Because the pressure regulator also reduced the pressure in the garden hose. I had one blow up once (a long, long time ago). That's when I decided the regulator had to be attached directly to the shore water spigot first!

Since then, I fill my fresh water tank and pump from it. I still use a filter (sometimes), and it's attached at the end of the garden hose and before the trailer. Why? To remove any foreign taste from the garden hose.

I use one of the non-adjustable units threaded directly to the campground hydrant, a 5' hose, filter, then a couple of 15' hoses.

I would say that it would be easy to get in a hurry and leave the pressure reducing valve behind threaded onto the hydrant. I usually just leave it attached to the short hose.

i keep my regulator on a flexible “Y” connector on the campground spigot…then a 25’ no kink hose and the blue canister filter is located directly at the camper….i have a brass 90 deg fitting on the water inlet of fifth wheel…a 6” flexible hose on the filter and the incoming water hose connected to that.

we drink bottled water so the filter is not for drinking ..i change the blue filters seasonally and i always blow back thru the filter when i disconnect so i dont have water stuck in the filter.

Ditto on this.

Locally, I have excellent water in my area. Who knows what you're getting at some campgrounds.

Anyone ever camped around Flint, Michigan?

Regulator first. On two occasions I've had water pressure explode water filters. I eventually learned.

After traveling all across this country I'd highly recommend ALWAYS connecting an adjustable regulator, not the worthless little restrictor, to the park spigot 1st then add filters or whatever else after that. We were in numerous parks that had extremely high pressures, 100+ psi & others that were on a water wells that during times of low usage the pressures would increase considerably.
Recommend the same with the EMS on the power pedestal, every time everywhere you plug in.
Better to have both items connected all the time than to wish you would have had it that one time. IMHO both should be mandatory for every rv sold.

+1. Been using the same for almost 5 years. No issues. I use a "Y" then regulator, then filter, water hose, anti-kink adapter, then TT.

What Chuck said. I use the same regulator. Regulator first, than hose, then filter to RV. These regulators are adjustable . If there is enough water pressure, I run mine at 48psi. If water pressure is low, I’ll fill my freshwater tank and use my pump. It is also psi adjustable, and is set at 48psi. Never go above 50psi. I don’t find campground pressure below 45psi very often but it does happen. There was a campground stayed in with 105 psi and I watched my neighbor blow up his filter with it being the first hook up. An adjustable regulator is needed to adjust to these different psi at the campgrounds. Happy camping!

I usually have my regulator at the source. Most filters or filter enclosures will have operating pressure limits as well as the hose. Hot a filter or enclosure with 80 or 100+ psi it could blow them.
As long as you control the psi going into the RV you won’t have a catastrophe. Maybe a blown hose or filter.

Me to. I use a filter to fill my tank and just use the pump. No worry about over pressure or leaks. Or turning off the water when leaving the cg

Pressure regulator first, drops pressure right at CG connection, then hose, then filter with 90 degree elbow onto trailer connection. Since I have a valve that lets me fill the fresh water tank from the incoming supply I always keep it topped up in case I have to boondock. This way I only have low pressure filtered water in the rig. I use the in-line blue filters only because I haven’t had the time to come up with an easy way to add a larger filter.
