The weather is heating up and it’s time to open your inground pool. If you are new to opening a pool for the summer, this is for you. We show you how to easily open your inground pool so you can dive into the swimming season. Let’s get started!
By the way, if you have an above ground pool, head over to our article on how to open an above ground swimming pool.
Things You Will Need
Swimming Pool Net (skimmer net)
Pool Cover Pump (submersible pump)
Start-up chemical kit or your basic pool chemicals including chlorine
1. Clean Debris And Drain Water From Pool Cover
The best way to eliminate the accumulation of water is to use a submersible pool cover pump or sump pump. Or you can scoop the water with a bucket… but doing it this way can be a slooow process.
Do this now and it will mean less work later when it comes to cleaning your pool.
2. Take Off the Pool Cover And Clean It
By carefully removing the winter pool cover, you can minimize further debris entering the pool. It’s much easier if you have a friend to help you.
Once the pool cover has been removed, find a location big enough to lay it out so you can clean it. Next, apply pool cover cleaner or a mild detergent and use your pool brush to gently clean the dirt from the pool cover.
After that, leave the pool cover to dry completely before folding and storing it for the summer season.
A large waterproof storage box is a really good storage solution. If not, insects or rodents may take a liking to your pool cover and make it their home.
3. Remove Winter Plugs And Ice Compensators
Go ahead and remove the plugs you put in at closing time from return lines, the openings, including skimmer basket and return jets, also called eyeball fittings.
At this stage, all other winterizing equipment can be removed from the swimming pool too.
4. Add Water
If the water level is low or you reduced the water level as part of your pool winterisation, now is the time to fill the pool with water. Use a garden hose and refill the pool water to mid skimmer level.
5. Pool Pump & Equipment Set-Up
Now it’s time to set up your swimming pool equipment.
Put the drain plugs back into your pump and filter. Use thread seal tape to make sure there are no leaks. Put back any other gauges and drains that were removed.
Next attach the hoses by connecting the skimmer to the pump, the pump to the pool filter and then the filter to other equipment such as the chlorinator or your heater. In addition, if you do have a chlorinator, first connect the heater, then chlorinator and then return inlet. If there is no additional equipment, connect the hose to the return inlet.
Check the condition of the pump’s O-ring. You’re looking for any cracks or brittleness. And if you see evidence of deterioration, you should go ahead and replace the O-ring. Otherwise, lubricate it well with a Teflon-based lubricant and refit it.
Set the multiport valve to waste. Turn the pump on and let it run for about a minute. This is especially important if antifreeze was used when you closed the pool. Most of the antifreeze will run out during this process. It’s not a big problem if some antifreeze gets into the pool (providing you used the antifreeze for pools).
Now set the multiport valve to the filter position.
Start the pump. Next, listen for anything unusual and check for damage during the winter. Additionally, make sure the pressure gauge isn’t running overly high for long.
If the pump is running dry, turn the system off and prime the pump. To do this, remove the pump lid, add some water, close the lid and turn the pump on again.
Now is a good time to look at your filter too. If you have a cartridge filter, remove it and either wash it out or replace it.
Leave the pump running and the multiport valve in the filter position.
Great Job! You have now opened your inground pool!
6. Clean Your Swimming Pool
Remove debris with your skimmer or leaf rake.
Brush down the sides of your pool with your pool brush.
Vacuum the pool.

7. Adjust the Pool Water Chemistry
The ideal readings you are looking for are alkalinity (100-150ppm), pH (7.4-7.6), and calcium hardness (200-275ppm). Add chemicals as necessary to bring the levels to the correct range.
Additionally, it’s also a good idea to add a metal sequestrant. Over winter metals can increase. This product will help prevent staining of the pool walls.
8. Shock Your Pool
After a winter of hibernation, pool water should be shocked to sanitize the water.
We recommend this Pool Shock.
The ideal time to shock your pool is in the evening so the sun doesn’t use all the chlorine before it has had a chance to do its job.
Run the filter for 24 hours, test the water again to make sure the right water balance has been achieved. If the water is balanced, get your swimmers on and pool inflatables ready.
