Buying Guide


As we mentioned before, the market is filled with different types of sump pump at different prices. Furthermore, the criteria become different when looking for a sump pump specifically to use in the septic tank.

Choosing a sump pump for a septic tank can get tricky without knowing what features you should look for. So, in this buying guide, we broke down the same criteria we used to compile this list for you.

If you decide to look for more options even out of our list, this buying guide will come in handy. Let’s have a quick look at things you should consider before buying a sump pump for a septic tank.

Motor Power

Motor power should be on top of your priority list as it’s used as a general indicator of the pump’s capability. Usually, the power is measured in horsepower or HP. Most of the sump pump in the market have a half hp motor.

If you are using it for a septic tank, this amount of power should generate enough flow rate to get the job done easily. Sump pumps are usually considered power-efficient options, so there is no need to worry too much about the horsepower. If you think the flow rate is good enough at a certain height, that pump is probably good enough in terms of motor power.

Voltage Compatibility

Voltage is another crucial thing you should check out. Mostly, this information can be found in the product manual or description. To run a certain sump pump, you need to have a power line that matches the pump’s voltage. Depending on the motor power I mentioned above, a pump might need different volts to run correctly. Typically, the half-horsepower submersible and air pumps can run on 110 to 120 volts delivering optimal performance. If you opt for a sump pump with a high-power motor, make sure your household connection can back that up.

Build Quality

As the sump pump for the septic tank will be submerged in water, you should choose one with a solid build quality. Usually, these sump pumps depending on the type, plastic is used for certain parts while the main body is made of aluminum and stainless steel.

As the sump pump is a long-term investment, you need to be cautious about the build quality so that it can serve you for years. Additionally, the sump pump you are purchasing must have corrosion resistance; otherwise, it won’t last a year.

Instead of depending on the specifications, you can check out user feedback for more accurate info about the material quality.


If you are someone with no expertise in pump installation and wiring, this feature is essential. Generally, wiring a sump pump is relatively easy with essential knowledge and the help of the manual. But sometimes, the wire that comes with the pump has a stripped lead, which might take a little more expertise than usual.

Also, most of the sump pump has cables included in the package, make sure your unit has that. Additionally, some submersible types come with inbuilt control boxes like the Hallmark pump we discussed. That can be a great addition to any submersible pump. So be sure to check that out too.


After you have made your mind about every feature, the purchasing decision comes down to the price of the articular sump pump. The price depends on the power and flow rate of the sump pump for the most part. Unusually, sending a couple of dollars should give you a decent sump pump for a septic tank.

If you are on a tighter budget, again, there is nothing to worry about. Quite a few good quality sump pump comes in that price point that has decent performance. Just keep your expectation real, and you’ll be satisfied with the budget-oriented sump pump options too.

However, we would advise you not to cheap out as a sump pump for a septic tank is a long-term investment, and you expect it to last for years to come. 

Flow Rate

Flow rate carries more significance than any other feature, whether it’s a sewage pump, sump pump, or any other pump. Flow rate indicates the amount of water going through the pump in a certain amount of time.

Usually, for sump pumps, it’s better to go for a model with a high flow rate, But that also takes a toll on the pump’s energy efficiency. However, as we are talking about sump pumps for septic tanks, a flow rate of 20-25 GPM (Gallons per Minute) should suffice.

In the end, the flow rate comes down to personal preference and how fast you want to pump the water. You should choose a sump pump with a higher flow rate if you want faster pumping for our septic tank. Depending on the waste load, generally, bigger constructions need higher flow rate pumps.


Here we are at the end of the review. Long story short, you can keep your septic tank from filling up over time by installing these pumps. All the products we reviewed here are good options with positive feedbacks from the users.

All you have to do is fix your budget and pick the best one according to your septic tank system. Now that we pointed out how to identify a good sump pump, the decision should be pretty easy for you. In the end, we hope our review and buying guide has been helpful to you to make an informed decision about the best sump pump for a septic tank.
