Hello

I was getting about 5 gallons drawdown from my 8 year old 40 gallon
pressure tanks.

I have a 50' well. Recently, my water pressure started to go down to
nothing, and I noticed my untreated water looks green, not the usual
iron-brown color.

I decided to install a new pressure tank. I thought that solved the
problem...but no.

To regain water pressure, I turn on a faucet on and turn (on and off)
the incoming water valve (after the tank).

That works for awhile.

Any suggestions?

I'm not sure what purpose the incoming water valve does. It sounds to
me like:

A) Your well is going dry.

B) Your pressure tank is not charged correctly. With the tank
drained, the shrader valve on the bladder should show 2 PSI below the
cut-in pressure setting on your well pump pressure switch

C) Your pressure switch differential setting is too low.

Most likely B, then A, then C.

But that is just a guess based on limited information.

Although it is a common misconception, the water tank has absolutely
nothing to do with system pressure (unless it is totally waterlogged).
System pressure is set by the pressure switch.

In additon to what Stretch posted, a common cause of poor pressure is a
plugged water filter/softener. Others are corroded pipes, partly
closed valve, some crud partly blocking a fitting.

I bypassed both the water softener and iron filter and it is the same.

But by opening and closing the valve I can get water back.

Perhaps I should get a solenoid to that on the hour?
turn the water on and off?

I can't think of anything that would cause that effect. Sorry.

Debris getting lodged on the valve? Opening and closing the valve may
be allowing this debris to pass. I actually know nothing about these
systems though.
