Also, note the very important need for a check valve. Guess what it does?! Checks that the wastewater is only pumped out and that nothing comes back in!!
The size and power of the ejector you need. Things to consider would be…. How far does the sewage need to go to reach the mainline? How much space do you have for the basin? The price of an ejector sewage pump varies on a few factors…. Horsepower, which will largely be figured out when you answer the questions above. There is a lot of them out there!!
Keep an eye on where you buy your sewage pump system and make sure the manufacturer will honor the warranty! Keep in mind that this type of system will be difficult to fix, if for no other reason than logistics, so you will want to buy a quality product for your home.
Sewage Grinder Pump System Just like the basement sewage pump system, the sewage grinder pump system generally uses a float switch to indicate when the system starts to pump. The main components of this type of pump are as follows: Grinder tank Wiring leads — these bring electricity to both the grinder pump and the sewage pump Disconnect box — specifically for the grinder pump Drain inlet — approximately 4 inches of PVC piping that will connect to drains that are serviced by the pump Tank vent — since friction produces heat, the grinder will need to be vented.
This can be done out the inlet pipe or directly as long as there are no more than 4 feet between the tank and the vent stack. Drain gravity line — where the wastewater is brought into the tank thanks to good ole natural gravity! The ground outlet for sewage — a very important part as this is the discharge outlet that goes to the outside by passing through the foundation.
Highly Recommended, depending on the type of sewage grinder pump, a Concrete Tank Anchor — preferably about pounds which will prevent the pump from floating. Finally, A tank bed made of gravel — approximately 6 inches of pea gravel. Basement Sewage Pump System Once you have decided that your home or business is in need of a sewage pump, it is time to start considering what kind of pump would best suit your needs!
Many of these sewage pump systems operate on a float switch. What is that exactly?? You better look out!! If you are from the north, perhaps it might occur when the snow starts to melt. Here are a couple of important issues to check : The alarm goes off to let you know there is an issue with the float switch No power!?
Start with the easy fix first, check the breaker. The pump might be jammed, be careful checking this yourself! You should be able to bypass the switch and just plug the pump directly.
NOTE: You will have to manually plug and unplug every time you need the pump to do its job! Constant chirping? Bad smell? Try pouring a couple gallons of water, it may just be your lines are dry and need to be flushed. Sewage Pump Residential Sewage pumping became popular in the s, minimizing the dangerous task of sending people down into the ground to perform maintenance in a deep sewage pit. Sewage Pump System Installation So you are planning on installing a bathroom in the basement, great!
How convenient! You will definitely need to install a sewage pump system. The most important piece…. A small repair may be all that's needed. Next, you'll need to buy or rent a sewage pumping machine or submersible auger and sump basin. Sewage pumping machines can be rented from commercial cleaning services, or you can purchase one of your own.
Sewage pumping machine prices vary greatly depending on brand and model, but they generally range between ten and twenty-five dollars. The submersible sump basins are much more expensive at up to about three hundred dollars. Once the sewage system is in place, you should connect to the main sewer line to the bottom of the basement. Connect the lower drain pipes to the bottom of the sewage sump basin. Small sewage ejectors are for homes and commercial applications where toilet usage and wastewater loads are modest.
This vent prevents discharge line clogging and pump seal failures. Note that some grinder pumps include a vent opening right in the pump housing oppsite the float control.
Even so, the vent in the discharge line is still required. At bottom left of our illustration you can see the weep hole vent location for a typical grinder or effluent discharge pump discharge line marked and circled in blue.
This discharge line must be cleaned periodically. You should see water squirting out of this opening when the pump is running. It is necessary that all submersible sump, effluent, and sewage pumps capable of handling various sizes of solid waste be of the bottom intake design to reduce clogging and seal failures. If a check valve is incorporated in the installation, a vent hole approx. Vent hole should be checked periodically for clogging.
The 50 or 90 Series [Zoeller] pumps have a vent located in the pump housing opposite the float, adjacent to a housing lug, but an additional vent hole is recommended.
Watch out : Zoeller also issues this warning about use of vent holes on high-head sump or ejector pump installations:. The vent hole on a High Head application may cause too much turbulence.
You may not want to drill one. If you choose not to drill a vent hole, be sure the pump case and impeller is covered with liquid before connecting the pipe to the check valve and no inlet carries air to the pump intake. Water stream will be visible from this hole during pump run period. A float control switch is used to turn the sewage pump on and off. You just need to fix them on top of the pump using heavy-duty glue, according to the instructions on the manual. At this point, the pump is ready for testing.
You can easily test the pump by filling the sump pit with water. This will trigger the float switches to activate the pump. If the pump fails to function, you might need to set up the float switches again. Also, make sure that the discharge pipe takes the shortest route to the sewer line.
Before attempting to install a sewage pump , it is imperative that you apply for a plumbing permit from the local authorities. Additionally, you have to allow for a thorough safety inspection of the building before you can proceed with the project.
Fortunately, these processes are relatively easy and straightforward.
