How to increase water flow AFTER the filters?

Ok, I recently installed a RVwaterfilterstore.com filter system. The filter sequence is: a 1 micron sediment filter, a .5 micron carbon filter and the final one is a metal trap canister. The campground I permanently camp at has strong well water pressure (65 psi) and great flow. After I connected the filter system the water barely flows from the hose and all the fixtures in the camper have less than ideal water pressure.

So, I would like to keep the filtration system but need an increase in water flow after the filter system. How can this be achieved?

how can filters be parallel ?
don't they have to be in series

sediment > micron > charcoal taste filter

in parallel sediment would clog the other two

and sulfur taste in the water is not removed by a sediment filter

the water has to go thru each stage sequentially

each stage is going to add some restriction to flow rate
I can explain it to you.
But I Can Not understand it for you !

Only other possibility I can think of t the moment is the Ys you are using.
look in them they almost all are squeezed down to nearly a quarter inch, especially the ones with valves fro both sides.
I have found a few full flow Ys or splitters but they are plastic or shiny plated junk metal that no on wants.iahve lookedin the aisles of Lowes, Home Depot and Ace and some others and they are all the same junk, with different labels.
Full flow splitters or Ys should be out there I just haven't found them yet.
Three filters in Paralel should have very little flow restriction unless...they are stopped up with sediment

Doesn't make any sense. Nobody would buy filters if they blocked as much water as is claimed in this thread. Something is setup wrong or broken.

or as I stated before, use multiple filters in parallel.

Well, Higher filtration higher resistance to flow.
In previous psot I tried to rule out any things that might have possibly clogged up the media.
Since that wasn't it then the obvious that we all experience.
Higher filtration more resistance to flow, then larger amount of same filter media will increase the flow.
The more effective the media the higher the resistance to flow, and the more and smaller particles etc is filtered out and the more often you have to replace filters. In South Georgia, northern Florida, and La and in Michigan among others we have run into low pressures and mud and iron an sulfur etc and bad stuff.
We have turned n the water pump and the water from the tank added to the volume and pressure, except when the pressure exceeds the pump's output pressure setting or capability.
We have had to flip the lever and fill our tank and then use the wter from the tank through the pump.

But as far as filtration restriction larger filters of the same media is the only way I can think of.
I've seen the three filter setups advertised, with larger micron pores and just filter media in the first filter housing to get sediment, and it is the cheapest filter and the most frequent to be replace, and the type of media in the second and third one to et smaller bugs and one to get metals and poisons etc.
I've done the same thing with individual filter housings and on and on.
No way around it the better the filtration the more restriction. Bigger filters the only solution, or fill your tank and use the filtered water. A water pump set at 65 psi, the one we have is sold to be used on ac instead of dc at 65psi...but our with dc motor only delivers 5 gallons a minute at 55 psi. I do love a shower from an 80psi source like we encountered in Ky, though and the filters did take some pressure out. The biggest problem is the plumbing especially with the new pex and the cheap clamps at joints.
So bigger filters and housings seems the only solution.

Well I was going to suggest higher pressure park side of filter but 65 is about as High as I'd care to push that (well 70)

The small micron filter is likely the culprit a larger micron filter might help increase flow.

Another option. one I use for totally different reasons is to fill 'er up and use the onboard pump and storage tank.

My Reaons are 2 fold: Originally the city "Super Chlornated" and my coffee tasted like bleach even after a carbon filter. So I recalled some fish tank instructions and filled the on-board. Without pressure the bleach vanished swiftly and coffee tasted better.
Then my wife died
Now I go up to 4 weeks on 80 gallons (or more) which is the capacity of my tank

Summer I spend half my time in one CG half in another moving every 2 weeks. So I only hook up at the one park (The other park) here I run on tanked water and save the work of the hookup.. Same for sewer hookup (Tanks are well matched) and the result is I have a very nice 50 amp pull through site here that I like (it is clean and level) and management likes that I like it cause there is no sewer so nobody else likes it. Don't bother me. So I'm basically not tying up a site when I'm here.
Home was where I park it. but alas the.

Have a pressure gauge installed before filters and see what it reads when you turn on your water.

You said 3 part system
Each part is going to add restriction to the flow of water
If I couldn't resolve the issue
I would use the filter system with a fill hose and
Fill my tank, and use my water pump
It might not be ideal, but it eliminates the issue of the sulfur odor, which is why you bought that system
I can explain it to you.

I have not run three but have run two in series. Perhaps and only perhaps this is contributing to partial blockage or restriction. On thing I have doe in fill the tank when pressure is low then use from the tank. Our last water pump would kick in when it was on and water pressure from the outside source was low and bring pressure up. This new identical pump not quite the same even though rated at 55 psi. Does your coach have its own pressure requlator somewhere set to 45psi?


Carbon filter was flushed of fines prior to install, per instructions. There is no onboard pressure regulator on my RV.

If you were to put a pressure gauge on the outlet side of the filters or at the faucet you should see the pressure as the same as at the source. When you open the faucet and the flow slows its an indication of a volume issue. .5 seems pretty small but as mentioned others have used them. Pressure is created at the pump and builds when you shut off the faucet. Again, volume and pressure are two different things. You say increase the pressure after the filters which you might think could be solved with an additional pump after the filter but it doesnโ€™t work that way. You would then be restricting the intake flow to the pump. Some pumps are damaged by low intake flow because they can have cavitation


You are correct, I mixed up the terminology. I edited the original post to reflect the correct information.

Hereโ€™s another idea. I originally had a weeping toilet valve issue which I figured was a spec of sand or dirt in the valve seat. Thatโ€™s when I installed two Home Depot GE filters. One is sort of a woven cloth and the other is carbon and Iโ€™ve had no more toilet issues. We then bought a Berkey Traveler water filter set up. Its a little smaller than the regular model and serves two people well. The two primary filters last a long time and two additional filters can be used to take out much smaller stuff. You could still use whatever part of your filter system that would take the grit and other stuff out. The Berkey is a very good filter

The Berkey can sit near the edge of the counter or they sell an optional chrome steel stand to set it on so its high enough to fill a cup or whatever

I used two filters in parallel to get double the flow rate.

First, troubleshoot the system by removing one canister at a time and checking the pressure/flow after each removal.

Second, if you can't isolate the trouble by removing individual filters, then use a different strategy. Fill your water tank, turn off the external water source, and use your water pump to pump water from your tank. The pressure should be much better.
