Pressure loss
Recently had a faulty check valve replaced on a well pump, and I have had problems regulating the water pressure since. The pressure tank itself is not losing pressure. It has been tested. The pressure in the tank is 35 psi. The pressure switch is set at 40-60 psi. The (I believe it's called) dead head pressure of the well pump is around 90 psi. There are no leaks to the house or in the house. To see what might be happening, I run water until the pump kicks on. I turn the water off and wait for the pump to shut off. After it shuts off at about 60 psi. I turn the power to the pump off. I let the system set without water usage for 6 hours. The pressure dropped from 60 psi to about 52 psi. That drop happened within the first 15 min to 1/2 hour then it stablized at 52 psi and did not move form there for the next 5-1/2 hours. Do you have any suggestions.

When you say there are no leaks in the house, are you certain that water isn't leaking past a toilet flapper valve?
If water is leaking past the flapper valve, then the toilet will fill incrementally to make up for the loss. Try turning the stops off at the toilets for awhile to see if the drop in pressure persists. |

I awoke to a complete lack of any water pressure. I checked the tank and it showed 20lbs of pressure. I found no leaks and no fuses were tripped on the pump. What should I check next? What could be the problem?
I recently made two changes and am not sure if the two are related. First, I changed both elements in my hot water heater which, unfortunately, didn't give me any additional hot water. Second, I changed my kitchen sink from one with a single handle to one with separate handles for hot and cold. ...
Here's the deal: Have seen a slow but sure loss of hot water pressure in the five plus years we have been in the house. Water source is a well, so lime and minerals are likely to blame. Pipes are copper. Water is heated through the furnace, a Smith (Westcast) 8 Series boiler-burner unit. We...
Our house is on a slab. We have copper pipes. Just recently and rather abruptly we began to lose water pressure. When we turn on the shower the water pours out for about 10 seconds and then drops off to a near trickle. We have not changed or added any fixtures. The showers are both single handle...
We recently bought a home and a few weeks after we moved in the water pressure in the shower went crazy. Sometimes it happens less than a minute after you turn on the shower; at other times, you can make it through your shower without any problems. There is a sound like a "thunk," then the water...
