Can a foot valve get clogged?
A clogged foot valve could be reducing the rate at which the pump can pick up water from the lake. A worn, damaged, or debris-blocked impeller in the pump itself could be the trouble as could an air leak at the pump (do you see bubbles in the output water?)
How to diagnose and fix bad or total loss of water?
How to fix complete loss of water or water pressure/flow at a building: This article describes how to diagnose the total loss of water pressure and the need for water control, tank, piping, water supply main pipe & valve, or water well repairs. We discuss: Loss of municipal water pressure or flow – diagnostic guide.
How long does it take for a water pressure tank to recover?
[Click to enlarge any image] Photo: the main water shutoff valve at a water pressure tank (white arrow). In 8 days, if the problem was that your well was exhausted, it would have had time to recover. So the problem is probably one of the others listed above on this page. Start by asking if you are in a climate where piping may be frozen.
When to see water pressure at intermittent loss?
Water flow in the building simply stops dead. By contrast with these “no water at all” causes, if water pressure in the building gets very low or stops but later recovers, you have an intermittent or other water system problem and you should see a different diagnostic procedure found at WATER PRESSURE INTERMITTENT LOSS
When do you need a pressure reducing valve?
This condition occurs at buildings where there is a large water supply main to an apartment or office building whose water demand can vary enormously (0.5 gpm to 100 gpm) depending on the building occupants. Watts and other pressure reducing valve producers recommend a nice solution to this problem.
What does a leaky foot valve in a well do?
A leaky foot-valve or check valve allows water to drain slowly down the well piping and flow back into the well. At some point, this will reduce the pressure in the pressure switch, causing the pump to cycle back on to increase the pressure.
What causes a foot valve to not work?
When the system doesn’t hold pressure on the well side I think there are no leaks in piping, check valves, foot valve, pump body. So when a pump still won’t develop pressure I think that there is an impeller, seal, or voltage problem. Sometimes a 240V pump will work at low voltage or even at 120V depending on its design, but will be weak.
Where is the foot valve on a well pump?
This article series describes the foot valve used on well piping for water well Pumps & Water Wells: we explain what a foot valve is, how they work, why they are used, and how to diagnose troubles with this special in-well check valve found at the bottom of well piping in some wells.
When to use a foot valve in a jet pump?
A foot-valve is only used in a jet-pump situation (where the pump resides above ground and shoots some water down the well to help lift more water back up).
