We are at a campground with high water pressure and use a regulator(we always do)and a filter. By the time it gets to the tap, pressure is really low...if I take the filter off it's ok. Do you think the filter (it's new) somehow slows the flow even more?

Do you think the filter (it's new) somehow slows the flow even more?if the regulator is one of those cheap, screw-on types you might want to take it off and see if the inside pressure changes. it's sure one or the other.

Could be a couple of problems. What is the micron rating on your new filter? the lower the micron rating the more restriction placed on water flow. Have you removed the regulator to see if flow improves? We upgraded to a whole house regulator by Watts which I set at 60 pounds. it made a big difference in flow. Lastly have you cleaned the screens in the end of your faucets lately. Every time I check mine I find build up from hard water which restricts flow. On my last coach there was a back flow valve in the coach water supply that I had to remove as it was restricting the flow too much.

In general, flow rates for sediment filters are higher than for equally sized carbon or media filters. The tighter the filter, the slower the recommended flow rate is also a generalization you can count on. One manufacturer, for example, gives the following maximum flow rates for its pleated 9.75" X 2.5" filter cartridges:1 Micron Absolute -- 3 gpm.2 Micron Nominal -- 4 gpm.5 Micron Nominal --7 gpm.20 Micron Nominal -- 8 gpm.50 Micron Nominal -- 10 gpm.Carbon block cartridges in the same size are usually rated at a maximum flow rate of 1 gpm, and if serious chemical removal is expected, the flow recommendation would be slower.so yes the filter can effect flow.

Turn water source offDisconnect hose from city water connectionTurn water on and check flow (with regulator & filter in place)Then check flow without filterHow high is CG water pressure?What type of regulator....brand.....fixed or adjustable?What type of filter...whole house/canister or in-line screw on type?Also check city water inlet screen/washer......is it dirty?Have you tried the on board pump.....any change in flow vs city water?Have you removed/clean faucet aerators?

If you haven't done it already, place the filter before the regulator. Then their pressure drops do not add together.

Is the pressure just as bad with water pump only. Mine did this, an A Change of filter did the trick.

I just got my new filter cartridges that I ordered online. This is the replacement element for the under the counter water filter. This is a 3M filter element so it is not some cheap Chinese knock-off. On the enclosed paperwork, that I usually throw away, it states that the service flow rate of the filter is 1.5 GPM with an input pressure of 25-125 PSI.
My water pump has a flow rate of 5.5 GPM which is one reason why the flow rate for the kitchen faucet is less than that at the other faucets.
