If you’ve already tried draining a hot tub by connecting a hose to the drain and waiting for the water to clear out, you will be delighted with a drain pump solution.
Drain pumps drain the water by dewatering the hot tub leaving only a few inches of water in minutes, not hours. They are also useful for many household tasks that require transferring water from one place to another.
But not all pumps are suitable for all household tasks. Sometimes it is even better to have several different pumps. And with so many available on the market, it can be difficult to choose a pump to purchase. That is why we’ve put together this article to help you make the right choice.
We’ve had a look at several different pumps and we not only announce the winners of our research but we also help you figure out what to look for when choosing a pump and, as a bonus, tell you the best pump for a flooded basement.
Do you want to make your hot tub last 3 times longer?
90% of success is in proper hot tub maintenance. To avoid (or prevent further) leaks, you should follow the hot tub care schedule and use the proper chemicals.
We know how it may seem confusing; that’s why our team has created a complete hot tub care guide and we reveal the tricks that the manufacturers would like to keep secret.

It’s important to note that this is because the EZ-6878 is also larger and heavier than other sump pumps. It weighs 5.6 kg. For comparison, the Homdox 2112GPH weighs only 3.3 kg.
It comes with everything you need to simply plug in and start the pump. It comes with a hose and hose clamps to attach it to the pump.

Distinguishing strengths of this model are its ability to empty the bottom to a record 1/5 inch and its portability. It is ideal for emptying the hot tub and draining clean or slightly dirty water from any environment such as cellars, tanks, flooded cellars, flat roofs, etc. But not for use with saltwater.
It does not have an automatic shutdown, so you have to monitor it to avoid burning the engine. But this won’t be a big problem because you’ll probably be around the hot tub as it is emptied very quickly.
This pump has two main hose adapters — GHT 3/4″ and NPT 1-1/4″. This model also has a long 25-foot cable, so you may not need an extension. The only thing you may need is a hose clip, and the hose itself if you do not have it.
Bonus: The best anti-flood sump pump — WAYNE CDU790
Some sites recommend the WAYNE CDU790as a universal pump and even for use in hot tubs and pools. But it is not intended for these purposes. That’s why we decided to research the customer experience for this pump. The results impressed us so we decided to tell you about them. This information will be useful for you if you have a periodically flooded basement and you need a reliable pump.
❗ Importantly: The CDU790 is not intended to drain hot tubs or pools. It is used for water removal from the basement.
The WAYNE CDU790 is easy-to-install, reliable, and quiet.
The pump is not too loud and has a silent check valve, which is useful if you don’t want to hear loud sounds from your basement.
So, if you need to protect your basement from flooding, the CDU790 is the best choice based on our research, but remember not to use it for other purposes.

FLUENTPOWER FSP750DW
Power: 1/4 horsepower
Capacity: 1800 gallons per hour
Full Size: 7 x 7 x 12 inches
Weight: 3.7kg
Cable Length: 10ft
Hose Diameter: NPT 1-1/4″, 1-1/2″
Auto on/off: yes
A positive feature of the 3300GPH is the length of the cable. It has the longest cable, 26 feet. You don’t need extension cords. The float switch is adjustable to determine which water level position you want it to operate.
The pump can also be switched to manual operation by simply attaching the float to the side slot. With this, you can drain as low as possible (1.5″) but make sure that the pump does not run dry. Although it has thermal overload protection, it is better not to bring it to this point. Also using the pump for saltwater, chemical, or acid fluids, can shorten the life of the pump.
Superior Pump 92250
Power: 3/4 horsepower
Capacity: 3300 gallons per hour
Full Size: 15.63 x 9.96 x 7.83 inches
Dewatering: up to 1.5 inch
Weight: 3.9kg
Cable Length: 26ft
Hose Adapters: GHT 3/4″, NPT 1-1/2″
Auto on/off: yes
The strength of this model is durability. The frame of the Superior 92250 is made of durable thermoplastic, the shaft seal is made of stainless steel, and the motor winding is made of solid copper.
Also, you can adjust the float switch by changing its length or switch to manual mode. And maybe it’s better to switch to manual mode because some users have noted problems with the float switch.
❗ Notice: If you need a GHT 3/4″, it is not included in the package, it is purchased separately.
WAYNE Water BUG
Assembly quality and durability
Power: 1/6 horsepower
Capacity: 1257 GPH, 900 GPH at 10 ft
Max grain size: 1/16 inch
Full Size: 11 x 11 x 10 inches
Weight: 3.6kg
Cable Length: 10ft
Output: for pump discharge
Auto on/off: no
❗ Good for household needs, but not recommended for hot tubs and pools
The Water BUG is compact and user-friendly. Its main advantage is good quality assembly and durability. That is why the Water BUG attracts many customers who use it for various domestic purposes. While some people also use it for emptying hot tubs and pools, the Water BUG is designed only for clean water. Chemicals that are used in hot tubs can potentially cause damage to the pump. Therefore, the manufacturer does not recommend using it to drain hot tubs and pools.
If you decide to buy this model for other purposes, you should also consider the length of the power cord. It is only 10 feet long. You may need an extension cord and a waterproof connection. Or you can consider the Green Expert 203618 and the EZ Travel EZ-6878 which have a cable length of 25 feet.
How to choose a pump
For what it is used
First, decide for what purpose you need a pump. Basement pumps are mainly used in basements to remove moisture and flooding or for domestic purposes. If you’re reading this statement, you’re probably interested in a quick drain for a hot tub or pool. Although you may need it to handle other tasks.
If this is the case then it would be useful to know that some pumps are designed to use “clean water only” as the WAYNE Water BUG or just to prevent flooding as the WAYNE CDU790.
Speed (gallons per hour — GPH)
Pay particular attention to the speed of the pump if you plan to use it for drainage of large amounts of water.

Automatic on/off switch
If the pump runs dry for some time, it may burn out. Usually, sump pumps are equipped with a float switch. It switches off the pump when there is little water left or switches on the unit when the water rises to a certain level.
This function is critical for pumps used with floods. It is also important if you plan, for example, to drain the pool with a pump and do not want to wait a long time for it to shut down. The automatic switch is not critical for drying the hot tub, because it is usually a fast process.

Where to drain the hot tub water?
The rule of thumb would be to check with your local law on what is the best way to drain your hot tub. Generally, it’s safe to use your sanitary system connection.
- If you don’t use saltwater, and if you dechlorinate the water properly before draining, you can discharge your hot tub in your lawn.
- Never drain your hot tub in a stream, a river, or a lake, as it will damage the ecosystem.
- One more thing to be aware of is that a hot tub contains a lot of gallons of water so you must find the best spot that can take up all that water safely.
