How To Fix Pool Liner Not Tight In Corners
1. Remove The Pool Liner
It’s best to start by thinking about what is happening with the pool liner.
The right option is to take off the pool liner.
The reason you are going to want to remove the pool liner is to get a better look at what’s going on. This is when things can go wrong because you have to focus on the underlying details associated with the pool liner including its size.
If you attempt to fix the pool liner without taking it off, you are not going to get a good look at what’s happening underneath.
Start by removing the pool liner and then begin assessing the root cause of the pool liner not being tight in the corners.

2. Check For Possible Wall Shifting
One issue that can cause this to happen is when the pool walls begin shifting.
Since the pool liner is dependent on the size remaining the same, it is going to start to lose its shape around the corners when this occurs. You do not want this to happen as the wall shifting is the last thing you will want to see happen.
It’s important to make sure the pool walls are in good shape over time.
Look into this and make sure the pool walls are set up in a way that is going to hold up over time.
If the pool walls are shifting, it’s best to see what is causing this to happen. It might be the base is not stable and that has to be corrected first.
3. Check The Liner’s Size For Shrinkage
Is the pool liner the same size as it was beforehand?
You might want to take a peek at the liner’s size as soon as you can. Sometimes, a person will not have a grasp of this and that is what will hold them back.
You need to start assessing the pool liner’s size and then make adjustments along the way based on this information.
In general, when a pool liner shrinks, it is best to replace it. You are not going to get it back to size. This can happen when the pool liner begins to get older.
4. Replace Or Re-Install The Liner
You will always want to maintain two options in a situation such as this.
The first option is to simply replace the pool liner and this does work well as long as the underlying issue has more to do with the pool liner.
If it is something like the pool walls shifting then that has to be addressed first before you look at swapping out the pool liner.
If the issue had more to do with the water’s pH level then you might want to take off the pool liner and put it back on to see how things work out.
