3 Basic Types of Sewage Pumpsĭifferent sewage pumps are rated for different types of solids. Here, examples of solid waste a sewage pump may encounter can range from human waste to diapers, cleaning wipes to clothing. To do its job, a sewage pump may need to handle solid waste of varying sizes and consistencies along with liquid wastewater. For commercial operations, commode black water waste may be joined by other pathogen-contaminated wastewater.Ī sewage pump’s job is to prepare black water waste for transport and then assist in that transport. The most common source of residential black water waste comes from the commode. Sewage pumps handle black water waste, which means waste that is sufficiently toxic to need a separate routing system. What Is a Sewage Pump?Ī sewage pump is a compact appliance with a specific job. In this article, we outline everything you need to know about sewage pumps that you would not necessarily know to ask. The “PUMP UP” version will be used for LOW level alerts.Sewage pumps, like nearly every other home appliance today, come in a range of shapes, sizes and – most importantly – capacities.Ī residential sewage pump is going to have different use guidelines and capabilities from a commercial sewage pump.Īnd while every residence and business needs to have a system in place to handle sewage shredding and transport, most owners weren’t involved in selecting the sewage pump they currently rely on. The “PUMP DOWN” version will be used for HIGH level alerts. Also as explained earlier, you have “PUMP DOWN” and “PUMP UP” versions. No control switch will ever come with a plug, again because it will be wired directly to a control panel or alarm box. The main option you have is whether you want mercury or mechanical. This means they are very sensitive to changes in water level, which makes them great for high or low level alarms.ĭeciding which control switch to purchase is much easier. Narrow angle float switches on need to move 10 degrees to switch position. These switches are generally low amperage and what we call narrow angle. CONTROL DUTY FLOAT SWITCHESĬontrol switches are designed to connect to a control panel, mainly for high or low level alarms.

While mercury switches are said to be more reliable, they are not allowed by law to be used in some states (see our website) and are only available in 13 amps. Mechanical switches have a ball bearing on a track that moves back and forth. Mercury switches use a small amount of mercury liquid to open and close the contacts. The last option that you have available is whether to use mercury or mechanical. This splice should be done in a control panel or waterproof junction box to ensure that the connection does not get wet and cause a short. Floats are all two wire so to install on a pump you must splice the float switch in the “HOT” line coming from the power source. Pump switches without a piggy-back plug must be hard wired, and this gets a little more complicated. That is all there to it, your pump will only come on when the float is in position to allow it. The plug on the float switch will plug-in to a power outlet, and then the pump will plug into the piggy-back outlet on the back of the float. If you purchase a float switch with a piggy-back plug the installation is very simple. Our float switches come either with a piggy-back plug or without a plug. Once you determine which amperage float you need for you application a decision will need to be made about how this float will be installed. Our most popular floats come in the following levels: 13 amps, 15 amps, and 25 amps. Since the power for the submersible pump will be flowing through the float switch it will need to be able to at minimum handle that amperage. When choosing a float switch to control the operation of a pump, the first question that needs to be answered is about amperage. This is needed when controlling a pump because you have to be able to pump out a range of water and it also keeps the float from being interrupted by turbulence in the water. These are generally are wide angle which means they have to move 90 degrees to switch to the “ON” or “OFF” position. They can handle higher amperages than control switches. Pump switches are designed to control the operation of a submersible pump. CHOOSING THE CORRECT SEPTIC TANK FLOAT SWITCH PUMP DUTY FLOAT SWITCHES
