We have a Whirlpool refrigerator that's 2 years old which has always had slow running water since new. I noticed that when we remove the water filter water runs nice and fast, but with a filter installed, even a new filter, water runs slow. We discovered that some friends of ours actually have the same fridge and it suffers from the same problem. What can I do?
The filter will definitely restrict the flow, but it might be made worse if there is already a flow issue present.
Many DIY waterline install kits come with self-piercing saddle valves. Compared to the 1/2" pipe they are fitted on (and even the 1/4" supply line), the hole they make is relatively small which reduces water flow to the fridge.
Your best bet is to not use these types of valves at all and instead solder in a tee fitting with a new 1/4 turn ball valve. If you can't do this, an alternative is to remove the saddle valve and carefully drill a larger hole in the pipe, and then re-install the valve.
Look at it this way: with the filter installed, everything is okay, but without the filter, water runs extremely fast because it isn't being filtered.
Better slow and safe than fast and unfiltered, I say.
But seriously, unless the water you're feeding your fridge is pre-filtered and the pipes are all perfectly clean, you need that filter.
Of course, if you're going to filter your water anyway after it's cooled by the fridge (I can't see why, really), it's probably okay to not use a filter.
All water filters restrict flow to some degree. Generally, the more filtration/treatment the more flow restriction. If you are using an in-line filter, there are many types available. If you want to just filter out sediment you could switch to a simple (and cheap) particulate filter and probably see better flow. The ones that remove chlorine and some chemicals (charcoal activated) restrict the flow more; "residence time" of water contacting the filter media is required for the filter to perform as advertised, so restriction is required.
Like @alt said, bypass the filter if you want flow and don't care about the water quality/taste.
