A sump pump can easily help you remove water from a pool by simply pumping it out the discharge end, where you can attach either PVC tubing or even get an attachment to adapt it to a normal garden hose. Some utility pumps will actually come with these types of adapters already in the box so you can just connect your normal household hose to it and pump the water out into your yard. Your local hardware store can also help you to find the parts you might need to adapt from schedule 40 PVC pipe to any other type of hose to adapt your current sump pump to use as a pool drainage device.

If your pool is outside, or even if you are taking the pump with you to someone else pool, then you need a sump pump that is also portable. You will be looking for handles on the pump to assist you with carrying it around. If it is transportable, then you will need to also consider the outer casing of your sump pump. You will be looking for a sturdy casing that can handle everyday use and the knocks that may come with portability.

It may also be ideal to look for a sump pump that is not too heavy so as to make it easier to move around. Just imagine if you had to move it quickly in an emergency, or tell someone else to, how hard would it be for someone to pull a heavy pump out of a deep pool of water?

Choosing the Best Pump To Drain a Pool

Pump Flow Rating

Typically you will also want a more powerful sump pump to remove the pool water. A large pool can take quite a bit of time to fully drain down and you will want this to pump down as quickly as possible. The more powerful your pump is, the quicker it will drain the pool.

Pump Head Pressure

You also need to consider how far upwards you are going to need to pump the water out of your pool and to the drainage point. Pumps have a head rating and this means they can pump up to a given value in feet vertically. Also bear in mind that if you increase the vertical head you will have a reduced flow rate.

Bottom Suction

As you submerge the pump you will want it to fully remove the water. What you do not want is for the pump to labor and struggle when there is still six inches of water within the pool. For this reason you will need to look for a sump pump that has a water intake from the bottom and not the side. This will allow the sump pump to keep pumping even down to lower levels.

Frequently Asked Questions

How often should I empty or clean my pool?

Generally, swimming pools should be cleaned and maintained regularly whatever size and shape it has. At least twice a year, your pool should be fully drained to replace its water. This is also the perfect time for you to inspect cracks, stains, broken tiles, and other things that may cause harm or problem in the future. This is where submersible utility pumps or sump pumps come in handy to get the draining job done.

How do I drain a pool using a sump pump?

Simply attach your pump to a hose to transport the water to your drainage zone, put the pump at the bottom of the pool, then plug it in to get it to start pumping. You will want to monitor the pump as it is working to make sure nothing is sucked into the impeller and also when it gets close to the end so you can turn it off after all the water is drained. Any standard sump pump like the Wayne 57729 or utility pump like the Superior 91330 will work for this task.

The Wayne 57729 pump has an automatic on-off switch so you won’t have to manually turn it off when it is finished, and can push 3000 gallons of water per hour (or 1850 gal/hour if you are discharging it 10 feet upwards). The Superior 91130 pump is smaller and easier to move around but it is also made of plastic making it more likely to be damaged, and can only pump 2400 gallons per hour.

What if the water is not completely clean?

In a situation like this you will want a pump or swimming pool cleaner that can effectively handle passing of some solids. Some pumps are rated to pass solids, but they can still get clogged up from time to time. You can clear them and put them back to work if rated for passing of solids, you need a pump that handles dirt and debris well.

What about other applications or uses?

You may also have other reasons for using this type of sump pump. You should consider this whenever you are looking to buy your sump pump for pool drainage. You may want to also pump:

  • Hot Tubs
  • Pool Covers
  • Spas
  • Ponds
  • Rising water tables
  • Flash floods

Have you considered emergency situations?

What if there is an emergency? What is your basement is flooded? Well with a portable sump pump that you can quickly and easily attach to a garden hose and have pumping within minutes can be a real life saver.

Best Sump Pump For Pool Drainage

Both of these pumps are great choices for draining a pool and other water removal applications. They are both in Amazon’s Top Sellers list and have been reviewed many times with 4+ star ratings on Amazon. We feel that our number one pick is best for both having all of the above points and also having higher ratings by the customers on Amazon. The Superior 91250 pump would also be a great fit for draining a pool, but it does cost a bit more than our economical pick of the 91130.
