Some water pressure issues. Pressure switch and/or sediment filter.
We bought our house three years ago, and since day one, we've fought pressure issues that are more prominent in certain areas of the home. We are on a well (unsure of the depth as I haven't taken the casing lid off to see if it's marked) with a sediment filter inline after the pressure tank. We currently have a 30/50 pressure switch that is working fine.

Our hallway bathroom shower, and our kitchen sink suffer the most pressure loss. I have to replace the sediment filters about once every 1.5-2 months, and you can really notice a difference in pressure as the filter gets more clogged. Even when the filter isn't scheduled for changing, the pressure is very odd. When we turn the water on in the shower or kitchen sink, it will be relatively slow for 30seconds-1.5 minutes, then build pressure, then kick down pretty harsh after a while, then repeat. I've watched the gauge when this is happening, and the switch is kicking on at 30, and off at 50. I don't know if it's dropping quicker than normal or if the problem is that at 30psi, the pressure isn't sufficient enough.

Could my problem be the inline filter? Would I be better off trying a 40/60 switch instead to account for the loss of pressure through the inline filter? I'm pretty sure the bladder in the pressure tank is alright, but then again, I've been surprised before. Any thoughts?

Also, as a side note, why am I bringing up so much sediment? I grew up in a home with well water, and we never even needed a filter. Is it possible the well pump is too low in the well and is pulling from the bottom?

Most pressure switches are adjustable, there is usually a diagram inside the housing. I suggest you kick it to 40-60, 30 is a little on the low side. As for the sediment, the aerators on faucets get clogged easily, which results in reduced flow. If sediment in the water is a continuing problem, you can get a whole house filter to remove the sediment.

Sometimes the gauges get partially blocked. Try a new gauge, and see if you get the same results. Same thing with the switch. If it's turning on and off, it's probably working, but if it's acting odd, it may have a blockage as well. Depending on how the switch is installed you may be able to clean the piping out.
