No water in my pressure tank/ water pressure is low in house.
 
Hi, recently I noticed that we started having low water pressure in the faucets, especially in the shower. It will start off with a nice full flow, then eventually drops low. I went to check to make sure the well switch was on, and yes it was. However, when I touch the pressure tank, I was able to move it/ or rock it back and forth. It felt empty. It was very light as if no water was in it.

How old is the well pump?
If there is nothing open in the house and the pressure tank is filling up, How long does it take to fill the tank to turn off the well pump?
Could be that the pump can no longer pump the water to the tank and house.
The other idea is that there is a hole and a good size one at that between the pump and the house.
If you go to the well head and with the pump running you hear water spraying then there is a hole and best for a pump man or well driller to deal with fixing or if there is no spraying noise still a driller or well pump man to deal with it.
While it might cost a few coins over what you might spend on your own, the time in which they would get in and get it done will be less than the hours of going to and from the store to get the different parts to get back in water.

Could also be that your well is dry. The water level is too low and there is no water to pump.

When the pump shuts off, is the tank at least partially full of water. (Usually the pressure tank should not fill more than halfway (you can't see it) before the system pressure reaches maximum and the pump shuts off.

When the pump first kicks on (a sensor detects minimum system pressure to turn the pump on) the pressure tank should be almost empty.

Well the house was built in 1986. We moved in 2004, I don't know how hold the pump is. I also checked the pressure gauge by the pressure tank by turning off the power to well waiting a bit and turning it back on, It first went to 20 psi and then went back down to 10 psi. I also checked the air in the pressure tank and its at 28 psi. The pressure switch is a 30/50. Fed up and don't know what is going on. My fear is I may need a new well pump.

I can also hear the water coming in. However, there the water tank still has no water/ is not filling to where it needs to be. Tank is still empty.

Don't rule out the pressure switch going bad.

Can you manually override the pressure switch and get the pump to run longer? How high can you get the pressure to go (don't exceed the maximum set on the pressure switch)?

Going above 28 PSI the tank pressure and pressure showing on a gauge attached to a pipe should be about the same. (Below 28 PSI in the system the tank will stop at 28 or whatever the tank was set to, when the bladder is properly holding tight.)

Well pumps do not last forever , at some point they need to be replaced.

It is also possible that there is a leak in the line.

Have you gone to the well head to listen for spray?

Don't think the well is dry, went out there with a flashlight and I can actually see water.

Peaches1 03-31-2013 05:36 PM

The pressure switch is new, as well as the pressure gauge. My old pressure gauge was stuck on 55 psi. Wouldn't move at all. The new one i think is fine. It first went to 20 psi then held there a bit, then slowly went down to 10psi hasn't gone back up.

When the well is running do you hear water spraying? does the water that you see in the well go down?

Peaches1 03-31-2013 09:09 PM

No spraying in the well and the water doesn't go down.

Akpsdvan 03-31-2013 09:38 PM

My money is on the pump no longer able to pump water like it should.
A driller or pump man will be able to pressure and flow test the pump to make sure it is in need of replacement, but I would be looking at the pump as the reason.

Pump and Foot valve is what it looks like.

Peaches1 04-01-2013 09:12 PM

I want to thank all u guys for the help and ideas. Will be replacing the well and tank. I will also keep u guys updated on my results. Thanks.
