Bilge pumps can be categorized as either electrical or mechanical. Electrical bilge's pumps work by sending out electricity from a battery. This causes the water pressure in the pond to increase so that more water is pumped out of the waterway. On the other hand, the boat bilge pump works by using a mechanical pump to push the water through a hosepipe that is connected to a valve that shuts off the flow of water into the pond when it reaches a certain amount. The reason that one type of bilges pump is considered superior to another is based on their efficiency in moving large amounts of water through a waterway.
It is essential to note that the bilge pumps are mechanical water pumps designed for the removal of sewage water from the septic tank. As wastewater is present in the septic tank, electronic bilges pumps are usually designed to not produce large sparks as opposed to the traditional mechanical bilge's pumps. Electric bilge pumps are usually fitted with float switches that turn the pump on when the sewage volume reaches a certain level. In some cases, a pump will also have an alarm attached so that when it is triggered, the owner can contact a plumber.
In most cases, a sewage pump that is located inside the septic system is powered by an electric source. However, in some rural areas, there may be a need for a pump powered by natural gas. This type of pumping equipment is not only more expensive than its electric counterpart, but is more dangerous due to the potential for exploding gas tanks. Because gas is so flammable, the plumber must be notified immediately. It is important to ensure that gas has been vented correctly if there are children in the home or any pets.
If there is no septic tank or a septic tank is not located in the waterway, then there are two options for a pump. One option is the use of an air-vented pump. The air is blown into the pump's pump chamber, making it operate like a refrigerator. Because the air contains the same chemical makeup of the sewage water, the water remains constant throughout the operation. In this case, the only maintenance required is ensuring that the temperature of the air within the chamber is constant throughout the year.
Another option is the use of a traditional pump. As the name implies, these pumps are not vented and run solely off of an electrical source. This pump requires no maintenance and requires a large supply of electrical power in order to run. These types of pumps are typically installed above the bottom of the septic tank. In order to conserve power, these pumps can be designed to run constantly during the night when the pump draws less water from the pond. The downside to this type of pump is that they require more space and can be expensive to install because there is often a large hole in the bottom of the septic tank.
Before choosing the bilges pump for your pond, you should consider the size and location of your pond and whether or not you need a pump. If you need to pump sewage, you may need an electrical system or if the water is stagnant or filled regularly, you may need to invest in a pump powered by gas or a traditional pump. The cost of installing one of these systems may be more than the cost of an electrical system but in many cases, the benefits far outweigh the price and you will be able to enjoy the peace of mind that a pump provides.
