I am having a problem recently with the plumbing in my entire home. When I turn on a faucet, water pressure will be fine, but then after 5 seconds, the water pressure will diminish to almost nothing, but then it will come right back strong and pretty much stays strong depending on how long I am running the water. This same problem happens when I flush a toilet or turn a shower/tub on. It just started doing this a few weeks ago. Some details: I have well water, I just changed the inline filter 3 days ago because I thought it might be plugged. There was no difference after I changed the filter. Is this being caused possibly from a clogged vent? I appreciate any feedback!
