My pressure tank on my water system doesn't keep up pressure I am pumping from a private well in sandy soil


Question:I have changes teh filter, cleaned the screens in the faucets bt he presure is still low. The pump is submersible

Answers:
look at the points on your pressure switch. if they are burned or discolored then you need a new switch. turn off your pump at the breaker and allow th water in the tank to drain to zero psi. turn on you breaker and your pump and see if the water pressure returns to normal. then turn on a facet and watch you psi on your pressure tank. chances are (if it your pressure switch) that your switch will not cut on when it reaches it lower pump pressure ,normally bout 30psi. take an air pressure gauge and check your air pressure. if you get air then check the pressure to make sure it what it should be. if you get water then you need a new tank. the last option is that if your switch is working and the tank is ok then its a blockage somewhere or its your pump. chenck the tank first. (doesn't cost anything) replace the switch. (turn off the power at the breaker, take off the switch cover, look at how the wires are placed and then put in the new switch. you will also need to turn off the water from the well because when you remove the switch water will come out of the hole. make sure you use teflon tape or paint when you install the new switch.) if you find water in your tank then repalace it. get the biggest one that you can afford even if you don't need it. its better for your pump and your switches and it ensures that when you have that blowout party you won't have to worry about your water pressure going kaput when 90 people use yur toilet and you don't have to worry about that pressure surge when you take your shower. the bad answer is that its your pump. if it is replace it with a constant pressure pump. it has a variable speed and pumps based upon the amount of water you need.


u need a second tank to store the water,before it goes to the main tank
Perhaps your air blatter in the tank has a hole in it or the pressure is low?
It's also possible that the pressure switch is faulty.
Have you taken out the pump and inspected it?
you could have a ruptured line as well.
When it's out you can check the strainer on the pump.
