Guide to Sewage Grinder Pump Installation Parts & Procedures
Parts of a Sewage Grinder Pump System
The sewage grinder pump is housed in a plastic or steel reservoir which receives waste product from the bathroom or other plumbing fixtures information technology serves.
When a float inside the reservoir indicates that the sewage level has reached a loftier level in the reservoir, the float turns on the grinder pump which grinds and pumps away the waste material.
The pump shown at the superlative of this page is a sewage grinder pump which grinds the waste and pumps the solid/liquid measure to the building main drain. At left the sewage grinder pump parts include:
- Sewage Grinder tank (this is an Environment One Grinder Pump System)
- Lifting optics for removing the assembly (the circles at the mid-tank seam)
- Electric wiring leads for the grinder pump and septic pump alarm
- Electrical disconnect box for the grinder pump organisation
- Bleed inlet: 4" PVC tank inlet for connectedness to building drains served by the pump
- Sewage pump tank vent. The sewage grinder tank must be vented either directly or through the inlet piping and within 4 ft. of the tank to a building plumbing vent stack
- Drain inlet gravity service line - wastewater flows into the tank past gravity from this line.
- Ground sewage outlet: i 1/4" male person pipe thread discharge outlet (the small diameter piping leaving the tank at top correct and passing through the foundation wall)
- Physical septic pumping tank anchor (900 pounds, or nigh 6 cu .ft. of physical to prevent the tank from floating up out of the ground)
- Sewage Pumping Tank bedding gravel, 6" deep of rounded pea gravel.
(Sketch is from the Environment One Depression Pressure Sewer Systems Grinder Pump catalog.)
Sewage or Septic Grinder pumps grind the solid waste entering the system, then pump it to the building drain. The building sewer drain and so carries this mixture past gravity (a gravity primary system) or by pump pressure (a forced primary) to its destination at a septic tank and drainfield arrangement or to a municipal sewer. Septic grinders are intended for apply at residential or pocket-sized commercial locations.
Because the waste matter is ground and pumped under pressure, these pumps can lift high distances, say from a basement floor fifty-fifty to a street sewer which may be uphill from the home, or to a high pressure sewer main that may be located some distance away.
For example, we inspected a summer camp community which used this force-main sewer system to movement waste from buildings across a site covering several acres to a common septic arrangement.
Small sewage ejectors are for homes and commercial applications where toilet usage and wastewater loads are modest.
A typical home sewage grinder pump uses a one/3 to two horsepower electric motor which powers a grinder mechanism that grinds the waste, and an actual sewage waste pump which moves the ground sewage/wastewater mixture up a riser piping to its destination: the building main sewer drain, where the wastewater is carried to a septic tank or to a community sewer line.

- Electrical power for the sewage or septic pump
- Turn off electrical power to the grinder pump circuit earlier handling or installing the pump. The pump electrical circuit should exist properly grounded, without splices in the connecting pump cord. Don't utilize an extension cord to take power to the pump.
- Make sure that the pump basin or well is large enough in diameter to requite free movement to the float assembly without binding
- Don't elevator the pump by its power cord
- Electric circuit splices in damp or moisture area need to exist in waterproof junction boxes
- Install a bombardment-fill-in pumping arrangement if your edifice is subject to power outages
- Tape or secure the pump's ability string to the belch line and keep it well away from the bladder associates, sharp edges, moving parts
- Confirmn expert electrical ground: by electrical testing (DMM/VOM) that the electrical footing for the pump circuit is in fact connected and working. The pump motor should be connected using the mill-supplied iii-prong plug and it should be connected to a 3-prong grounded electrical receptacle.
- Pumping basin, well or chamber for the sewage or septic pump
- Exist sure there is no debris in the bottom of the grinder pump well or basin; remove small pebbles, sticks, other solid debris
- Be sure that the pump base can stand on a solid, flat, level base. Deepen the well appropriately if you need to install a concret cake or other support below the pump
- Provide a secure, child-proof bowl cover for the pumping chamber
- Plumbing for the sewage / septic grinder pump
- The discharge pipe must not be smaller in diameter than the bore of the sewage pump's belch pipe connection opening
- A bank check valve should exist installed in the pump'due south discharge line, otherwise information technology will exist pumping the same wastewater repeatedly at each pumping cycle.
- A check valve vent should be installed in the discharge line at the proper level.
See SEPTIC / SEWAGE PUMP Belch VENT for details.
- A gate valve or brawl valve should be installed ahead of a Unicheck or a marriage on the pump belch line to allow servicing the pump assembly
- Turn on electrical ability & test the pump operation by filling the pumping sleeping room with clean water.
Sewage, Grinder, Septic & Efflulent Pump or Sump Pump Vent Opening Requirements & Turbulence
The weep hole or sewage / effluent / ejector pump belch line vent pigsty permits purging of air trapped in the belch line at the start of a pump-on cycle. This vent prevents discharge line bottleneck and pump seal failures. Note that some grinder pumps include a vent opening right in the pump housing oppsite the float control. Fifty-fifty then, the vent in the discharge line is still required.
At bottom left of our analogy you can run across the weep pigsty vent location for a typical grinder or effluent discharge pump discharge line marked and circled in blue.
[Click to enlarge any paradigm]
Zoeller Pump and some other sewage pump manufacturers provide a combined union/check valve, [For case Zoeller's "Unicheck" valve]. Zoeller notes that with this valve is installed, the installer must drill a iii/16" (5mm) vent opening in the discharge line at a pinnacle fifty-fifty with the acme of the pump.
This discharge line must exist cleaned periodically. You lot should run into water squirting out of this opening when the pump is running.
The post-obit excerpt is from Zoeller (2009) cited at REFERENCES
It is necessary that all submersible sump, effluent, and sewage pumps capable of treatment various sizes of solid waste matter exist of the bottom intake design to reduce bottleneck and seal failures.
If a check valve is incorporated in the installation, a vent hole (approx. 3/16") must be drilled in the discharge pipage below the check valve and pit cover to purge the unit of trapped air. Trapped air is caused by agitation and/or a dry bowl.
Vent hole should be checked periodically for bottleneck. The 50 or 90 Series [Zoeller] pumps take a vent located in the pump housing opposite the bladder, adjacent to a housing lug, but an additional vent hole is recommended.
Spotter out: Zoeller besides issues this alarm nearly use of vent holes on high-head sump or ejector pump installations:
The vent hole on a High Head application may cause likewise much turbulence. Y'all may non desire to drill one. If you choose non to drill a vent pigsty, be sure the pump case and impeller is covered with liquid earlier connecting the pipe to the check valve and no inlet carries air to the pump intake.
Notation: THE [sewage, sump, or effluent pump vent] HOLE MUST Likewise BE BELOW THE Bowl COVER AND CLEANED PERIODICALLY. Water stream will be visible from this hole during pump run menstruum. - Zoeller (2009)
Set the Sewage Ejector Pump Float Control Switch
A float control switch is used to turn the sewage pump on and off. Be sure to set the switch position and to adapt the float positions that plow the pump on and off in accordance with the manufacturer'south installation instructions.
Most float switches used on sump pumps and sewage ejector pumps are set up to turn the pump on well before the holding chamber is at risk of flooding the building, and to turn the sewage pump off while the pump trunk or at least the pump impeller assembly is still below the liquid level in the chamber.

Guide to Non-Clogging Sewer Pumps
Not-bottleneck sewer pumps, or "non-clogs", are similar in principle to the grinder pumps discussed above, only they have more than capacity, and can move solids up to iv" in diameter to a sewer main or waste product handling arrangement.
Non-bottleneck pumps are used in some residential installations simply more than often in commercial or community systems or
at SEWAGE PUMPING STATIONS.

Got a sewage ejector station effect that you lot refer to is usually and air inlet valve not an air outlet valve so information technology's right that you should non smell any sewer gas at that location.
It would exist diagnostic to determine if the sewage scent that you lot are observing is coming downwardly from the rooftop vent at is stronger Outdoors or if y'all are smelling information technology stronger inside which would suggest there may be a leak in a vent pipe or drain system in the building.
I have a minor basement Holding tank below grade. The sewage is pumped up into the Ceptic tank.
There is a small vent pipe on the tank which opens into the basement. No aroma comes from the vent pipe. However, whenever nosotros shower anywhere in the house, we smell the sewage from the rooftop vent pipe. We tried extending the vent pipe but that doesn't work. What could be wrong?
Betimes
The pump inlet is higher up the chamber flooring, usually provided by the pump base of operations design or feet
Does the grinder pump set on the basin flooring or is the pump suspended a few inches above the floor ?
y does the pump shake wildly

IN a residential plumbing bleed organization that's connected to a private septic tank and absorption field, a septic pump, probably a sewage ejector pump if the right pump was selected, moves waste out to the septic tank.
If your property includes a physically separate graywater disposal system (similar a seepage pit that's separate from the septic organization) would the graywater be pumped to that different destination.
If you don't know if your graywater is being sent to a split destination and if you do not have a septic/graywater system cartoon and plan, and if y'all tin't detect one at your local building and zoning department, then you'd have to follow the pipes - which is a devil of a task if the pipes and ground are frozen.
I have septic pump inside of my house. Is the two" pipe with gray water , pumped out directly to the field ? , or information technology is routed through the tank. It'south freezing , and I need to know how it is routed nether the ground.

I retrieve I need to offering some more information: The location of the new toilet in my friend'south DIY remodel is not about an existing vent (over 15 ft), and venting up through the roof isn't an pick.
The reason he believes he needs the pump is that the soil line is too tight against the superlative of the crawl space to allow a Studor valve to be installed at the minimum required height.
The solution that was posed to me was to put the pump/basin in the crawl space nether the toilet with a Studor valve mounted to the bowl hat (36" higher up the lid, really) to provide venting for the pump.
Does this sound plausible? Someone else suggested that the one-mode venting from the Studor valve could cause methane to build up and risk rupturing the basin. I'g not on the hook for any of this, simply I want to offer the best advice possible. Thank you for your help.

As long as it'due south properly supported against tipping, and every bit long every bit the elevations piece of work with respect to drainage in to the unit of measurement, it does not take to be prepare into the ground.
I'm looking to install a septic grinder pump in a five' high crawl infinite with concrete floor. Does the bowl have to go into the basis or can information technology sit down on the physical floor?
