A Dictionary of Water Pump Water Tank Controls, Switches, Attachments. This article uses sketches and photographs to assist in locating and identifying all of the controls and switches found on residential water supply systems including the well, water pressure tank, water pump, and their associated valves and devices. We also provide maintenance and repair and emergency water shutoff tips throughout these descriptions. Well Water Pump Controls Switches What are the controls, switches, valves found on well water tanks and well water pumps, what do they do, how are they repairedDetermine Your Well Pump Flow Rate. Your well pump can pump water up to a certain maximum flow rate, in gallons per minute. For example say you could fill a 5 gallon. How to Identify Water Well, Pump, Tank Components Switches. In addition to the individual well, pump, and tank component photographs provided in the article below, our photograph at left has a number easy to identify water system components that happen to all be in one place The Well Casing itself is visible at the right of the photo, in the floor, to the right of the yellow shutoff valve. The black plastic well piping leading from the well casing top to a connection to galvanized piping which then passes by the pressure control switch to a tee where water can flow both into the pressure tank bottom to the right at the tee and into the building water supply piping to the left of the teeA well casing vent can be seen as the vertical copper pipe which forms an upside down U shape and is connected to a fitting on the cover of the well casing. This well vent permits air into the well during water draw down. Details about well casing cap vents are at WELL CAPS COVERSA water treatment chemical connection, probably from a chlorine injection system this well water is probably contaminated with bacteria can be seen as a clear plastic small diameter tube which is fed through a gray plastic tee in the black plastic well piping that connects the well itself to the galvanized pipe leading to the water tank and house supply piping. At the upper right in the photo se see two treatment tank bottoms black and white smaller diameter tank like objects partly shown. Well pump wiring is also visible twisted wires can be seen entering the well casing cap at the 1 oclock. A water softener or other water treatment system is probably installed besides a chlorine injection system, since. Water on the floor around the water tank and equipment looks like more than wed find from simple. NO RELIEF VALVE is visible in this photo one should have been installed and may be missing. This is a safety defect and in some jurisdictions a plumbing code violation. Unlike city water well water users are limited in the volume of water they can use at any one time. This is typically referred to as the yield of the well which is. Guide to Identification of the Water System Components Shown in the Page Top Sketch. The page top sketch is expanded by detailed photographs as we explain each of the components and controls of wells, pumps, and water tanks. In our sketch sorry the author is a technician but not an artist, you can identify the basic components of a private well system listed next but as youll see in our detailed articles and photos which follow, these components are not always located where theyre as easy to spot and name as in our drawing. Air valve Label 7 in the page top sketch and shown in the photo at left or Schrader valve looks like a tire valve. The water tank air valve shown in this photo is one that you should not normally have to use as its installed on a captive air or bladder type water tank. On water tanks that do not use an internal bladder, the air valve, or Schrader valve, used to add air to the water tank can be seen in this photo. Details are at TANK AIR INLET VALVE. At WATER TANK AIR, HOW TO ADD we discuss adding the right amount of air to a non bladder steel or glass lined well tank. And at WATER TANK BLADDER PRESSURE ADJUSTMENT we discuss fine tuning the pump pressure control switch to work perfectly with the exact air pressure pre charge in a bladder type well tank. Air volume controlLabel 6 and copper or plastic tube connecting the AVC to the water pump or a fitting nearby. An air volume control valve or device is not present. On captive air bladder type water tanks this control can take several appearances. Here is a photo of a different type of water tank air volume control. Details on using and repairing water tank air volume controls areat WATER TANK AIR VOLUME CONTROLSCheck Valves on water piping, well pumps, wells. Shown below. Check valves prevent back flow of water through piping for any of several reasons such as preventing loss of well pump prime by a check valve located at an above ground water pump or at the water pressure tank see CHECK VALVES, WATER SUPPLYElectrical Power Labeled SW in the sketch at page top Electrical switch at the water pump. See WATER PUMP ELECTRICAL SWITCHESFoot Valves on well piping are located on the bottom of the well piping, inside the water well. The foot valve helps prevent loss of prime in the well pump and piping system when the pump stops running see FOOT VALVESGauge Label 3 Water tank pressure gauge. The water pressure gauge on home water systems is one of the most helpful and simple devices used in diagnosing poor water pressure and pump, well, or pump control problems. This gauge has broken cover and needs replacement. See WATER TANK PRESSURE GAUGE for water pressure gauge explanation and repair advice. We discuss gauge problems with air or water pressure gauge readings on water tanksat How to Read Water Tank Air Pressure Accurately. Piping Labeled from pump well at left Well piping bringing water from the well to the water pressure tank and building. See WATER SUPPLY DRAIN PIPINGPiping Labeled to house fixtures at right Building water supply piping a main water line leaving the water pressure tank and bringing water to the building and its fixtures. See WATER PIPE CLOG DIAGNOSISand WATER PIPE CLOG REPAIRPitless Adapter shown in sketch below the pitless adapter provides a water tight connection that permits the well piping to pass out through the side of a round steel well casing. Our illustration above left shows a low pressure well spool using a clamp on pitless adapter in a design suitable for artesian wells whose head pressure is equal to or less than 5 psi a head of 1. Michigan DEP. We illustrate and discuss the use of pitless adapters at PITLESS ADAPTER. Also see. Low Water Cutoff for the Well Pump Many sources, including the Penn State School of Forest Resources recommend installing a low water cutoff device to protect a well pump that has to operate in an inadequate or low yield well. That resource describes an electrical low water cutoff switch. A low water sensing device to protect a well pump may be installed in an intermediate water storage tank, for example. If your well pump has stopped running and an electric low water cutoff switch is installed youll want to check that the switch is working properly. Details about electric and other low water cutoff devices to protect the well pump from damage are described in detail at WATER PUMP PROTECTION SWITCHPump Water pump either at or close to the water pressure tank or located separately in a well pit not shown in this sketch or in the well itself shown as pump at far center right in sketch at the top of this article. The water pump shown in this photo is installed right on top of the water tank and it is easily identified as a one line jet pump since we see only a single pipe entering the pump from the well the black ABS piping coming into the pump from its lower left.
