Need more information, loss of pressure where? Thanks

John

When the washer is filling I have no water upstairs in the kitchen or the bathroom

Age of house? Material of pipes? Pump or city water? If on city water Is there a PRV, (pressure reducing valve) installed? Problem just came on all of a sudden or was it gradually? Let's have more information. Cheers, Tom

Once again respond to Tom's question, Thanks.

John

1970,copper,well, it has beengetting worse over about 1 year. This well is 5 years old new pump and tank at the same time

Post just once not 3x. Pressure is likely fine but volume very low. Do you have an outside spigot, how is its flow? Done any plumbing work recently? We will have answers after we hear back from you

Sorry new at this. Yes out side is fine (the one closest to the well, the one one opposite side of house is weaker). No new plumbing work in about 4 years, except new field system this past June.

When the washer is filling, I have no water upstairs in the kitchen or in the bathroom.

Do you know how many gallons per minute your pump is producing and at what psi?

No I don't, all I know is that is a Gould 1/2 hp

If you have a water softener, put it on bypass and see if the problem is still there. Also check for a water filter and change it if you have one.

I tried bypassing the softner, still the same. We don't have any filters.
Thanks

Bladder or pressure tank? If a bladder tank what's the charge on the bladder tank? What's then cut in and cut out limits on the control box? Any air in the lines? Any dirt in the aerator screens? Let me know, Tom

Bladder tank pressure is 28 psi, limit switch says 30-50. Screens at the faucets are clean.

Also the pressure starts good at faucet then gradually drops.

What's the pump doing during this loss? Does it kick on attempting to build the pressure back up? On the front hose bib does the pressure drop when you run it for any length of time? Back to you, Tom

Pump doesn't come on until the pressure gauge drops.the hose will go and neverlose pressure, does this sound like build up in the lines or possibly the pump ?

The hose doesn't lose pressure, no matter how long it runs, the pump will kick on when the gauge pressure drops.

Is there a cut-off valve where the pipe enters the house?

Yes,after the bladder tank and this will shut off all.
