If you need to conduct water out of your home from a fixture that can’t be connected to a gravity drain line, you’re going to need a drain pump. Maybe you’ve got a laundry tray in the basement, or a washing machine, water softener, dehumidifier, or a similar project involving basement remodeling–the possibilities are varied. Whatever you’ve got going on, it helps to have a compact and low profile drain pump on your side–something that can fit under a sink or out of the way and simply pump out water when you need it to. So what are your options for draining gray wastewater below gravity lines?

While it’s possible to get away for a few months or maybe even a year with a cheap box store drain pump, as plumbing consultants interested in long term solutions, we always recommend spending a bit more to get a quality product that’ll last for many years without needing to be babysat. We reviewed the Zoeller 105 recently, and found it great at expelling water from a range of devices, including dishwashers, garbage disposals, air conditioner condensate, and mop and bar sinks. A good drain pump should be able to last for 10 years or more without even a hint of a need for replacement. Today we’re going to look at another strong candidate in the field: theLaundry Pumps 404 1/3rd HP Residential Drain Pump. It’s compact, fast, fully automatic, and reliable, and we recommend it heartily. Our full review is below, and you can buy it here.

View and Download Liberty Pumps 404 installation manual online. Automatic Drain Pump. 404 water pump pdf manual download. 1/3 hp 115V Polyolefin Automatic Residential Drain Pump. Part #LIB404 Item #3077352 Manufacturer Part #404 $ 257.25 EACH. Horsepower: 1/3 hp.

Key Features of the Liberty Pumps 404 Laundry Pump (60 Second Summary)

The Liberty Pumps 404 is a fully automatic residential drain pump designed for indoor applications involving draining water from fixtures and appliances against gravity. The pump includes a 1/3 horsepower motor with the standard 3 year Liberty Pumps warranty. The motor runs at up to 3,450 RPM on 115V AC at 60Hz and is oil-filled and thermally protected. It can pump up to 2,100 gallons per hour (35 gallons per minute) at zero feet. This figure drops to roughly 1,380 GPH at 10 feet, 150 GPH at 20 feet, and shut off occurs at 21 feet (max head).

The Liberty Pumps 404 is 11-1/8 inches tall, 13-3/4 inches in diameter, has a total basin capacity of 4.3 gallons, and weighs 13 pounds. It includes a 1-1/2 inch FPT inlet, a 1-1/2 inch FPT discharge, and a 1-1/2 inch FPT vent. It is capable of handling solids up to 3/8 inch thick and fluids up to 140F. The power cord is 10 feet long and is a 3 wire grounded plug.

Liberty Pumps 404 Feature Comparison With the Zoeller 105

Compared to the Zoeller 105, there are some advantages to the 105 and some advantages to the 404. The 105 technically has a higher maximum water ejection speed at 2,580 GPH vs 2,100 GPH, but the peak speed will be highly dependent on what’s being drained and the drainage path, which means that both will likely have the same effective draining speed. The 105 can handle slightly larger solids at 4/8 inch vs 3/8 inch in the 404. On the other hand, the 404 can handle slightly hotter liquids at 140F vs 130F. The max head on the 404 is slightly greater at 21 feet vs 19.25 feet in the 105.

The warranty is significantly better in the 404 at 3 years compared to 1-1.5 years with the 105. The 404 also comes with a slightly longer power cord at 10 feet vs 9 feet, which can make it slightly easier to install. Aside from the increased warranty span, perhaps the most significant advantage of the 404 is that it arrives fully assembled and ready to install out of the box, while the 105 does require a few additional steps since it isn’t an all-in-one sealed unit the way the 404 is.

Our Short and Long Term Experiences Installing and Using the Liberty Pumps 404

Installation is about as easy as it gets for a drain pump, even if you have next to no plumbing experience. The instructions are clearly written, detailed, and easy to follow; you essentially connect the pump to your septic line via PVC or flexible tubing, connect it to your laundry sink or appliance, vent the pump, add and set up a check valve, plug it in, and you’ll be off and running.

Once installed and plugged in, you’ll barely notice the 404; it will start quickly when necessary and shut off as soon as it’s no longer needed. Operation is fully automatic and should stay that way for the life of the device, which will typically be at least 10 years in most scenarios.

Troubleshooting and Installation Tips to Get Your Liberty Pumps 404 Working Sooner

Keep in mind that you’re going to need a few accessories to install the 404 on your own. For example, you’ll need either flexible tubing or PVC pipe of the correct diameter to connect the pump to your external drain as well as to your sink or appliance. You’re also going to need piping for venting the pump. To connect that PVC or flexible tubing, you’ll need three threaded adapters or fittings. You’re also going to need a check valve to prevent water from flowing backwards into the pump and forcing it to run more than would otherwise be necessary.

Venting can be done with a simple pipe setup, such as through an open 6 inch pipe. Make sure that the check valve is installed upstream of the pump (before your dirty water gets to the pump); this will also help keep sewer gas out of the pump. If you patch the pump into an existing drainage connection (e.g., that for a sump pump), you’ll want to make sure you have a check valve installed in your discharge line as well, preferably as close to the 404 as you can get it; this will keep water from flowing back into the pump or into your sink or appliance. We recommend a quiet check valve like the Brady check valve.

Liberty Pumps 404 Pros, Cons, and Value Comparison

In conclusion, the Liberty Pumps 404 is easily one of the best drain pumps you can buy today at the $200 price point. It’s quiet, fast, compact, reliable, easy to install, automatic, and simply works. The highest praise we can offer a pump is that it does its job so well we forget it exists, and the 404 delivers on all fronts. Our only recommendation would involve upgrading to the Liberty Pumps 405 if you need more of what the 404 delivers, particularly in the areas of power (1/2 HP vs 1/3 HP), speed (3,120 GPH vs 2,100 GPH), and maximum liquid temperature (180F vs 140F), and maximum pumping height (34 feet vs 21 feet).

Sewage grinder pump / sewage ejector pump or sump pump odor diagnosis & cure:

How to diagnose & cure sewer smells at septic or sump pumps. How to find and fix the source of smells coming from a sump pump it, effluent pump system, or sewage grinder or sewage ejector pump installation.

This article series gives installation and maintenance advice for Sump Pumps, Sewage Ejector Pumps, Septic Grinder Pumps, Sewage Pumping Stations, & Septic Pump Alarms. We discuss sewage grinder pump types, sizes, voltages, horsepower, installation and maintenance.

We also provide a MASTER INDEX to this topic, or you can try the page top or bottom SEARCH BOX as a quick way to find information you need.

Sewage grinder pump leaks & odor complaints

What to check when troubleshooting odors or smells from a sump pit, effluent pump, or sewage ejector pump system:

The following advice is excerpted from SEPTIC / SEWER ODOR SOURCE TABLE. See that more complete article if you are having trouble tracking down the source of sewage or septic smells at or around a building.

• Check the grinder pump for a valve failure, causing sewage backup
• Check for a loose, damaged, leaky, or lost cover gasket at the sewage grinder pump
• Check for a clogged vent on the sewage grinder pump (not present on all systems)
• Pour clean water into the sewage grinder pump or ejector pump pit sufficient to pump out sewage water before leaving the system out of use for a month or longer.
• OPINION: do not rely on drain cleaners (that can damage the pump) nor on chemical additives or deodorants poured into the grinder pump system. Even if such chemicals give odor relief the effect can only be temporary as they will be ejected when the system is used.

Question: septic pump grinder pump smell complaints & advice

(Feb 18, 2015) mike.ice@hajoca.com said:

We have two septic pumps in our building. One is for a small break room and the other services two large bathrooms. We have a terrible smell coming from a larger septic grinder pump and I was concerned about what chemicals I can pour down the drain to eliminate the smell. I know bleach reacts with ammonia creating a toxic gas so I didn't want to put anyone at harm.

Is there anything I can do to prevent this odor? It does have a large 4' vent that goes straight to the roof and we sealed all the cover plates and holes with silicone sealant but the smell is still strong and leaks into our hallways where customers come through. What can I do?

Reply:

Mike, rather than pouring chemicals I'd look for the problem source to find a more long lasting and safer solution. A venting system defect, missing check valve, or a leak, for example, may be at fault.

Question: Use of chemical treatments to control odors at a Zoeller sump pit ?

6 June 2016 Pete Beck said:

I have 1/3 HP Zoeller sump pump. Can I use a chemical like the ones used to keep black water odor under control in travel trailers and motor homes,to keep my sump pit from smelling, w/out damaging the pump...Thanks in advance for you help....Pete

Reply:

Pete, you don't indicate which Zoeller pump you have instaalled, nor am I sure (since you use the term 'sump pump') if we are discussing a de-watering sump pump installation or a sewage (blackwater) ejector pump.

I'm guessing the latter since you refer to 'black water odor'. In that case odors shouldn't be coming out of your pump system. For **example**, referring to Zoeller's Instruction Manual for the company's effluent/sump/de-watering pump (notice this is not a sewage grinder pump), for a wide range of Zoeller pump models (( Zoeller Pump Model 55 / 59, 70, 73, 75, 139 Series, 140 / 4140, 145 / 4145, 160 / 4160 Series, 180 / 4180, 191, 371, 372, 373 Series effluent & de-waatering pumps as well as Zoeller pump models 211, 212 Series, 270 / 4270 Series, 280 / 4280, 290 / 4290 Series sewage pumps (again these are not grinder pumps),)) available from the company's online literature library, you'll read that to control odors the company cites two features:

1. Gas-tight seals are required to contain gases and odors.
2. Vent gases and odors to the atmosphere through vent pipe.

Liberty Automatic Drain Pump Model 403 Troubleshooting

So I'd start by checking those features of your installation. If, for example, your system uses a loose cover that's a very common and correctable source of sewage smells.

Use of chemical additives and treatments, depending on the chemical, might not harm the pump but shouldn't be necessary. And harsh or caustic chemicals may also damage the pump. Zoeller includes this warning in the service checklist for the example manual we cite:

Abrasive material and adverse chemicals could possibly deteriorate impeller and pump housing

You don't say if you're connected to a private septic or public sewer - beware of dumping treatments in volume into a septic system. Search InspectApedia for SEPTIC TREATMENTS & CHEMICALS for details.

If you don't have the manual for your Zoeller pump, contact the company at the address we give below.

Watch out: tracking down the source of sewer gas odors or septic smells can be tricky. At a recent inspection looking into a complaint of sewer odors in the kitchen of an older home, with the homeowner we ultimately traced the odor source to dry traps in floor drains in the basement below.

This pump manual pertains to the following pumps in the applications recommended by Zoeller:

Notes to the Table Above

Zoeller's notes include:

1 Effluent systems should specify that pumps should not handle solids exceeding 3/4” in order to prevent large solids from entering leeching fields, mound systems, etc. (70 Series have 3/8” solids capability. 50, 140/4140, 371 and 372 Series have ½”, 130 Series has 5/8”, 145/4145, 160/4160, 180/4180 and 373 models have 3/4”.)

Where code permits, sewage pumps can be used for effluent systems. Non-automatic pumps with external-level controls are recommended for septic tank effluent applications

Watch out: note that the company explains that you may use a sewge pump for effluent systems - that is, for pumping clarified septic effluent up to an absorption bed, soakbed, or drainfield or leaching bed. The converse is not true, that is, you should not use a pump intended for effluent or de-watering to try to pump raw sewage. It will clog and fail.

Watch out: to reduce the risk of clogging and also pump seal failures, a vent hole and check valve may be required in your installation.

See CHECK VALVES on DRAINS, SEWAGE PUMPS, SUMP PUMPS
and

See SEPTIC / SEWAGE PUMP DISCHARGE VENT

Watch out: proper electrical wiring, including proper electrical grounding and ground fault protection are necessary for liquid handling pumps such as these in order to reduce the risk of fatal electrical shock.

Reader Comments & Q&A

On 2019-10-19 by (mod) - not normal for there to be a sewage odor coming out of a condensate pump

It's not normal for there to be a sewage odor coming out of a condensate pump and into occupied space. Something's wrong with the installation.

On 2019-10-19 by Maggie

I live on first floor of 9 story condo bldg. the grinder pump is in the basement right below my unit. When it comes on, then cuts off, bad sewage odors come up through my bath sink and tub drain, plus I assume the toilet as well.

It is a very gross smell... radiates all through my condo. Management says nothing is wrong with grinder pump. But smell emits right after it shuts off. My throat and head hurts most of the time. Is this dangerous?

On 2019-09-14 by (mod) - sewage ejector pump doesn't require treatment chemicals

No, Joyce, a sewage ejector pump doesn't require treatment chemicals to work properly. But it is important to install the right type of pump - one that can grind and dispose of solid waste.
If your toilets don't flush check the reservoir at the pump: if it's overflowing or backing up there then most-likely either the pump's not working or the sewer line (septic system) is blocked.

On 2019-09-14 by Joyce

Sump pump replaced approximately a year ago. Recently noticing an occasional flushing problem. Does this type of set up need periodic chemicals to keep it running effectively?. Similar to a RV set up.

On 2018-09-21 by (mod) -

Thank you for asking, Sue as you pose a frequently-raised concern about septic tank odors vs. additives.
A properly working and installed septic tank and conventional drainfield never requires the use of any additive nor booster, no chemicals, no treatments, nothing except the normal wastewater that flows into the tank.
Some additives and treatments harm the system, others contaminate the environment and are illegal, banned from use in many jurisdictions.
Enzyme type treatments are generally harmless and some may be useful to help de-clog in-building drain lines of organic deposits that clog or slow drains.
But the septic tank doesn't need them

I have black clumps that are tacky and smell like a sewage that has clogged my outlet hose nd pump now it only shows up during hard rain but my question is what is it and how do i prevent it thank you

On 2017-04-05 16:06:20.509238 by (mod) -

Brenda,
If the lights go OFF in part of your home when some other equpment (like a sewage pump) is running, then there is an electrical short or failing motor - that is an UNSAFE condition risking electrical fire or shock as well as a sewage backup. It sound as if you need a licensed electrician on-site.
Let me know what you're told and we may be able to offer other suggestions.
Daniel

What name of box thats set under mobli home and when it go out it makes light go out on one side of house

On 2016-12-31 by (mod) - septic tank lid needs to be repaired and sealed.

Sounds as if the lid needs to be repaired and sealed. Yes you can drain a dehumidifier into the sump pit provided it's piped so as to avoid any possible sewage backup out through that drain.

On 2016-12-31 by Charlie

This past week I noticed a sewage smell in the basement of our recently purchased 2nd home, which seems to be coming from the grinder pump. The previous owner put caulking in a hole on the lid, but it dried out and some of the caulking is missing. I also noticed the lid moves, but can't tell if there is a gasket around the lid.

Is it wise to put a dehumidifier hose into the hole and caulk around that hose, as well as caulk around the edge of the lid to prevent odors from escaping the grinder pump pit?
Thanks for your help.
