I recently moved to a home with a well, previously only living in homes with
city water.

The previous owners had valves set to bypass the water filter. A few weeks
ago, I opened valves to divert the water back through the filter. In the
past week, the house water pressure has dropped significantly. If I close
the flow to the filter and reopen the valve to bypass the filter, the
pressure is fine. A couple weeks ago, I also drained and refilled my hot
tub, which required alot of water.

What's going on with sudden low pressure through the filter line? The
filter looks OK. Incoming and outgoing water is clear.

Also, my well tank had a preset pressure of 38 psi. There is a pressure
gauge between in the incoming house water and the tank that reads 50 psi.
Does this mean the air in the tank is 50 psi, and is this too high?

Try replacing the filter first. Even though it may look clean, it could be
saturated with particles causing the lack of pressure

I am not familiar with maintenance on filters but yes, the filter is
the problem. Probably clogged. Require some kind of back flushing or
replacing he medium.

As to the pressure. Not enough information. Is your set-up running a
'constant pressure' system, i.e., does the guage show the pressure
going up to a certain pressure - cutting off- then coming on at a lower
pressure? Or does the guage show the same pressure all the time? You
need to watch the guage while you are drawing water to check.

If it is the most common type - has a hi cut off/low cut on the proper
tank precharge is 2 psi below the cut-on setting. That is set by
shutting the pump off and then drawing all the water you can out of the
system (empty tank).

Normal setting for that type switch a

20-40 - rare as 20psi is not really very acceptable on sprinklers,
showers, etc.
30-50 - common but even 30 psi will give problems with some sprinklers.
40-60 - common and very nice performance throughout the range.

Settings above 40-60 are not recommended for residential use as they
cause excessive stsrain/wear on fittings.

Your reading of 38 with a guage reading of 50 (if it varies) would be
correct for a 40-60 set up.

I haven't worked with a constand pressure set-up so I can't answer if
the 38 setting is correct for those.

Assuming a simple candle type sediment filter, you can replace it yourself.
I do mine every 6 months or sooner if they look very dirty.

Filters have different micron ratings. A 2 micron filter will plug with
particles larger than 2 microns and a 20 micron filter won't catch
particles smaller than 20 microns til it starts to plug up. I 2 micron
filter will also restrict water flow more than a 20 micron filter will.
Personally I prefer the better filtration of the smaller micron
filters.
I banked 4 ea 1" inlet/outlet filters in parallel so I could have my
smaller micron filtration without sacrificing Gallons per minute of
flow.
If filter plugging is a frequent problem you might want to install an
automatic back washing filter 1st in line.
You should also check to see when the last time your well was
serviced. With some wells it is necessary to redevelop them
periodically.
One method is to pull your suction line and run a 3/8" or 1/2" line
attached to an air compressor down the well. This will bring sediment
up out of the well and help clean your screens. Be prepared to divert a
lot of water. Also you need to anchor your blow line or your air line
will shoot out of the well like a missile. Fun to watch, but not the
preferred method.
