Question about Plumbing

I bought my home in 6/09, there is a omnifilter wholehouse water filter u25 installed, in the basement. On the top of the product it says bypass. My question is What does this filter do exactly and what maintenance should i be doing on it? I would really like to get a hard copy manual for this system, any suggestions?

Inside the housing is a replaceable filter cartridge. Filters used for this type whole house filter housing come in micron ratings from 5 micron - 50 micron. The smaller micron the finer it filters (that is not always good because it can significantly reduce flow rate and pressure in home). 30-50 micron filters are the most common used. The filter should be changed every 3 months minimum and sanitized with a a cap full bleach when reinstalling filter. Omni filter housings are notorious for the bypass leaking when turned and the bypass freezing up to where it won't turn. There are no manuals for this.
You can find filters at most any hardware store or water treatment company.

I have a Maytag French Door Bottom Freezer / Refrigerator. Model MFI2568AEW. I changed the water filter today and 10 seconds after installing the new filter it started making a very loud noise like

Sounds like water hammer, has the water supply got it's own shut-off valve behind the fridge or in the basement ? Try shutting the valve then open it just a little. Perhaps the water supply was opened fully after installing the new filter.

Ge smartwater wholehouse waterfilter main housing failed flooded house

Why did it fail? How did it fail? Was it the plumbing that failed? Replace it with a Pentair filter housing, 10" housing, 20" housing or Big Blue housing and make sure it is plumbed in properly. It is very unusual for a filter housing to fail unless it freezes up.

Water filter is so effective that it clogs completely very quickly. At $45 or more, 5 or 6 replacements a year seem excessive. Is a less efficient filter or a bypass the answer?

Hi and welcome to FixYa, I am Kelly.
Actually there is another alternative and that is to install an in-line water filter behind the refrigerator. If your having to change filters that often then your either on a well system or your local utility water supply is nothing short of very bad. In line water filters are much cheaper and by installing another IN-LINE filter behind the unit it will make your expensive filter last a lot longer. I have had to double up filters on well water and utility water systems where particulate persists in the water supply. Each filter is only good for about 500 liters / 132 gallons of water. The more expensive wall mounted type ones can supply up to 2000 gallons. Lowes, Ace, Menards, Home Depot et al.

Thanks for choosing FixYa,
