How to increase water flow AFTER the filters?

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 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.

Dont confuse pressure with volume as you trouble shoot. If your pressure at the source is good then you have a flow/volume issue. Trouble shoot with a process of elimination. 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 doesn’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.

Here’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. That’s when I installed two Home Depot GE filters. One is sort of a woven cloth and the other is carbon and I’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.

The link holds 60 gallons. but you can get smaller ones (And larger ones) Camping world has some listed as well assorted sizes For you I would choose 15 or 30 with transfer pump

Water Bladder

Small storage space needed Also a towed to haul it
