Replaced Whole-House Water Filter - Now Low Flow

[69RoadRunner]

replaced my whole-house water filter today and went to fill the fresh water tank. It was filling VERY slowly.

I flipped the valve and went inside and had low pressure to the sink.

I used the same filter that came with the coach.

I had removed the old filter last fall when I winterized, so I wasn't 100% sure about the installation.

I pushed the end with the O rings up into the lid on the coach and then screwed the housing over it.

Did I do something wrong or forget something?

When I was dewinterizing with no filter, flow was fine (although it did say, "Kiss my grits").

If you remove filter and have normal flow would say the filter is faulty. Check new filter outlet with ring and see if hole is plugged with some plastic or something else.
Do you have old filter try using that and see if you have better flow.
Make sure there isn't a "O" ring stuck in hole, where you plug in, from old filter.

Also check the screen where the hose attaches to the inlet...mine has clogged in the past and limited the flow.

What micron rating? Possibly to high, we are using 30-no problem.

[69RoadRunner]

What other brands fit? Mine didn't have a micron rating.I'm at Ocean Lakes in Myrtle Beach. I had to be pulled out of my site when I sunk axle deep in the sand/ dirt while straightening out.More later when I can use my laptop instead of the phone.

Hi 69RoadRunner,
MB has a lot RV parts places. Consider taking the filter to CW and any parts place the CG recommends. They should be able to provide choices.

There is a RV parts place right next door to Ocean Lakes. I believe its part of the CG.

I went to several & none had something that would fit.I bought one that screws on to the hose connection and removed the one in the factory canister.I didn't see anything blocking the flow.

[GaryKD]

When you made the change to the screw on hose filter, did you see a difference in the water flow?

[69RoadRunner]

Flow was much better, as expected. I know the filter is the problem because flow was good 2 weeks ago when I dewinterized with no filter.

I suspect you have installed a very fine filter that filters out most everything and jas a low micron size. These reduce the flow volume substantially. If the filter says it removes cysts, various germs and most chemicals, then it will be one of these. If it just filters sand and off-tastes, it will be a simple carbon filter with a coarse (high micron) mesh and the flow rate should be high.

Verify that you have restricted flow to all the fixtures. If it is just one or two fixtures check the screen/flow restrictor at the faucet outlet. This is often overlooked.

There are TWO measures of importance in a water filter cartridge replacement 1) micron (size of particles trapped) AND 2) flow rate in GPM. You can buy a very fine (1-5 micron) filter with a very low flow rate (1 GPM) which tend to be the cheapies and the typical filters sold in the big box hardware stores and camper supply stores OR you can look around for the a 1-5 micron filter with a 5+ GPM flow rate for which you'll pay a little more for. It is hard to find flow rates on filters, you might have to look up the specs online for certain filter models.

It is NOT correct to say that all fine filters have low flow rates. Installing a higher flow filter will solve your problem AND you CAN get fine micron filtration as well as flow. The filters from the RV maufacturers are almost always very low flow - i.e. lower cost.
