If you're proceeding on your own, mark and label each wire and each terminal that it was connected to so that you can replace the wiring correctly later. 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 you'll see in our detailed articles and photos which follow, these components are not always located where they're as easy to spot and name as in our drawing. When the liquid is below both switches, they are both closed; the pump runs, filling the tank. See Figure 4 for the various ways switches can be drawn. Try and make ladder type diagrams. Our current flow is from the power source, through the switch, through the load, and to ground. But since both low-level switch L and seal-in relay A are open, the pump motor does not start.

Take a look at the controls described at Question: what's the right air charge for a bladderless water pressure tank? See Detailed descriptions of individual water system parts and controls, valves, switches, pumps, piping, etc. The layout is designed not for parts location, but to explain how everything works. A is to open and when it is opened, an exhaust fan will turn on. The detailed, step by step procedure for inspecting and adjusting the water pressure control switch is discussed in detail at. We have no relationship with advertisers, products, or services discussed at this website. If you wish, still more excruciatingly-exact details about adjusting a pressure control switch, including which way to turn the larger range nut and the smaller differential nut are found at At 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.

But what if I tell you that you can do it with just two wires? This well vent permits air into the well during water draw-down during pump operation. Reader Question: how do I replace the well pump pressure control switch shown in this photo? Shown here is a Homart submersible well pump relay switch. Field inspection worksheets are included at the back of the volume. June 14, 2012 Mack said: Replacing pressure switch on bladder-less tank. It has higher electrical ratings for direct control of motors in pump and compressor applications.

Ordinarily, there will be only one load in a circuit. The system will all be low voltage to save on wiring costs. We discuss these well or water pump control questions: What are the functions of the well water pump pressure control switch, water tank relief valve, water tank gauge, water pump relays, water tank valves. This actually happened to a plumber in New York state, making pressure relief valve believers out of plumbers in the area. You can see another close nipple in your photo above - between the galvanized pipe tee and the metal to plastic bushing that adapts the whole setup to fit into that white plastic fitting between the green and yellow arrows in our annotated photo.

. We need to wire both float switches back to our control circuitry, plus we have to add the contacts and seal-in relay A. When you unscrew the pressure control switch from the pipe tee shown in your photo, the close nipple will either come out with and remain attached to the switch bottom or it will remain screwed into the tee. Some knowledge of basic electronics and the ability to read simple wiring diagrams is needed, but with proper research and a little practice, the average do-it-yourselfer can develop basic wiring skills. A familiarity with electrical tools and their uses is not hard to develop. In fact, it is a good idea to label the terminals on the controls if there could be any chance of using wrong terminals on a control. The Type G switch is diaphragm actuated and has contacts that open on rising pressure.

A more general answer is that every pump-operated water system will have some kind of control that turns the pump on and off. On a T87F, R makes to Y on temperature rise. We need to start a fan and light a light, two more loads. Click to read our privacy statement. If your pressure tank and pump controls are not inside the building they may be located in a basement crawl area or outside in a well pit.

How to Construct Wiring Diagrams

Some other types of water pumps such as constant-pressure tankless systems may use a pump that contains its own built-in pressure switch. When the circuit requires these pilot devices to use more contacts than they contain, it is common practice to let a set of contacts on the pilot device operate a control relay. When motor starter M1 de-energizes, the pump motor stops. The tee, what your instructions call a tank cross unit, incorporates threaded fittings and tappings to accept all of the necessary connections to the water pressure tank: the pressure control switch, pressure relief valve, water inlet from the well, water outlet to the building, a tank drain, and in some cases, a shutoff valve for the line feeding the building. Should the water tank rupture, even at fairly low pressures, a bystander could be hurt or even killed. Since we will be dealing with simple diagrams, a good rule of thumb is to remember that a typical circuit consists of a power source, a switch, a load, and a ground. Everything from float switch installation to troubleshooting will become easier.

Water Pump Presssure Control Switch Replacement Procedure In the sketch at page top the water pump pressure control switch is indicated by the green arrow; we show this switch in more details in photographs provided below. Watch out: If your pump pressure control switch is controlling a higher capacity submersible well pump, the electrical wires leaving the control may feed a separate heavy duty pump relay switch rather than going directly to the water pump. Be sure to check with local building codes in deciding between type of cable and possible need for conduit. We could eliminate the R8222D if one wants to use the auxiliary switch. The next line up is for a high-high-level alarm i.

So i put my neutral wires there, making sure i've got the line, or load part right. Poles refer to the number of switches operated by a single force. Special symbols may be used to show the operating force that activates the switch. Image: pince image by YvesBonnet from Wiring electrical devices requires a certain amount of experience, but with proper preparation, the novice can successfully perform simple wiring tasks. The contacts of the control relay are used to control the motor starter and the two pilot lights. Note: As always, please make sure the unit is off and unplugged no power before attempting this repair. In our photo at above left as well as in our article above, at you can see photographs of the water pressure tank cross unit or water tank tee we are discussing.
