Why no water pressure from well tank?

Answer 1

It sounds like you do need to put air in your tank. Look here for a fairly clear description of the process: gremcoinc.com

The exact process will depend on your system.

No. Low air in the tank would only make the pump run more. Pressure is a factor of the pump and the well. The tank will only hold the pressure built by the pump. You could have a clogged screen at the foot of your well, a bad pump, or build up in your waterlines.

*If the pressure is fluctuating, the foot valve in the bottom of the well might need replacing. This is a check type of valve that sometimes fails when sediment gets in it. They are cheap and some are made of plastic. If this is not working properly, it will allow the water to seep back into the well. This valve keeps the water pressure up between the well and the pump and/or storage tank. The tanks bladder might be faulty with a small tear in it as well.

Is there a pressure regulator in the line? I've had pilot holes plug in pressure regulators for home water systems that don't allow the spring tension of the regulator to be in sync with the water pressure it's controlling. A simple cleaning of the regulator pilot hole with a small wire solved it instantly.3

Ans 3 The respondents above have little knowledge about how a deep well system works ! First, - low air in the tank will NOT ONLY make the pump run more , -it will not give an adequate pressure to the house - regardless of how much the pump runs . Second, there is NO foot valve in a deep well system, there is a screen, but the chance of a screen becoming blocked is miniscule. The entire issue of a foot valve that will allow water to 'seep back into the well' is only relevant to a well of 70 feet or less. That is NOT a deep well !

- A 'bad pump' is simply ridiculous ! -A deep well pump will either pump or not. There are NO in-betweens !

The questioner obviously has a tank problem. -If a galvanised tank, it needs to have air inserted PROPERLY to about 30 psi. If it's a bladder tank, then the bladder is shot and tank must be replaced. There is a slim possibility that the pressure switch is faulty - or the well is not replenishing fast enough. -These issues can only be assessed by someone who knows how the system works.

Assuming that you are referring to the water pressure found in residential Plumbing, there are a number of factors that can cause the pressure to be lower than normal.

The "main" water pipe that serves your neighborhood or community has broken. It is also possible that local plumbing has been damaged, such as a broken water supply pipe for the residence.

The plumbing fixture through which the water exits is constricted. Very often this includes a build-up of tiny pebbles and debris behind the filter screen that is located in many faucets.

The neighborhood demand for water is high. In other words, there are more households using water than the water supply system was designed for. This will likely occur during peak demand periods.

If you are referring to the water pressure found in machines or systems that are designed to operate with water, then the answer will depend of which machine or system.

Answer 3

The well water tank gets pressure in only 2 ways - 1 -from residual air pressure in the tank ( this is normal and should be 2 psi lower than 'cut on' pressure.) - 2. A tank that has very low, or no residual pressure will only gain pressure when the pump is operating. This pressure will quickly dissipate when any faucet is used.

There are basically 2 types of well tank - the older 'galvanised' tank and the more modern 'bladder' tank. - Both have their problems. -In times of power loss, the air in a galvanised tank can be released if the faucets are used continually without the pump running. This air can be re-charged using a simple compressor. -In a bladder tank, the bladder actually holds the water and air pressure surrounds it, held by the steel shell. The bladder can eventually develop pin holes and lose the water into the air section. When this happens a new bladder is needed.

Low water pressure is often caused by these problems in well tanks.

It's possible that pump problems can eventually cause low pressure, especially in a jet-pump that has air leaks. -The other type of pump, a submersible (down the well) usually works or simply doesn't work. These pump problems can only be checked by a knowledgable person with a multimeter.

Answer 4

low velocity of water from the source

ANS 2 - There can be a number of causes and you don't give enough data for an informative answer. First of all, most people mistake tank problems with pump problems. - Sub- pumps can have problems with the vanes in the wet section becoming worn. Jet pumps can have problems with the impeller warping or becoming worn. Either type can have leaks in the pipe to surface. -However, the MOST common cause of low pressure is not enough air in the tank. The tank, whether galv. or bladder, MUST have sufficient air pressure to give adequate pressure in the house. Measure air pressure with a common tire gauge at the nipple on top of the tank - if it's less than 25 psi then that's the problem. Your best solution is call a well tech to analyse it for you (NOT a plumber)

Answer 5

The water pressure depends on the residual air pressure in the tank. Normally it should be between 30 -50-psi.

Answer 6

Gauge is not worth properly
