Let me show you the condition of our stock tank pool liner installation after 6 years of heavy use and harsh winters. As well as the updates and changes we’ve made to keep it looking brand new.
I mentioned in my last blog post that I was dreading tackling this project update, but in the end, the process wasn’t as bad as we thought it would be. Well, yes… it was a lot of work but knowing that we use it daily in the summer was definitely the carrot we needed dangling in front of our faces to get it done right away and not complain about the work.

Before I tackled the entire process of taking the liner out, I did research again, of course. That is always the biggest thing before starting any DIY project. And as I mention in my video, when we did this project in 2019, there wasn’t any information out there about pool liners for stock tank pools. I did read on Reddit now that there were people who had done it before but in 2019 I couldn’t really find any information about doing this. So while there were blog posts out about stock tank pools, there weren’t any DIY projects published about installing liners.
I do consider ourselves the internet pioneers of installing a pool liner, and all the blog posts now come based on what we posted. So now, 6 years later, there are many people who have installed a liner in their stock tank pools, and I checked out some of those projects as well.

Supplies used for the stock tank pool update
Step 3: Adding a pool liner pad to the stock tank pool bottom
Since we had issues with small holes on the bottom of the stock tank pool over the years, I decided to add a pool liner pad this time around. It is like a felt pad or foam underlayment.
My only worry is having to vacuum out water again, the way we used to every spring when it got between the liner and tank. The padding might make that process possibly more difficult. We had to patch several holes every spring.

I used a 12′ round pool liner pad. I simply placed it on the bottom of the pool and traced the tank diameter outline with a Sharpie and then used a sharp pair of scissors to cut the padding.
After that, I used the heavy-duty Gorilla Glue spray adhesive to secure the liner pad to the stock tank pool. I think this step is really necessary, considering the possibility of water getting between the liner and tank again and then having it bulge and wrinkle which would be a disaster.

Step 4: Adding the new pool liner and installing the inlet and outlet valves
Now, all we had to do was the same process as we did originally to install the pool liner. I cut the holes into the liner at the same spot and then used silicone sealant to the inlet and outlet valves parts after screwing them in place. It was once again pretty much like lining a metal trash can with a trash bag. No joke!
I did do a much better job this time at avoiding wrinkles. Check out my original stock tank swimming pool post to see how I cut the holes into the tank.

Step 5: Filling up the pool and checking for leaks
My husband removed all the rocks and gravel so we could add the liner on the outside surface of the pool. We also removed the old bamboo fencing. Then we filled up the pool while checking for leaks at the inlet and outlet valves.

After that, we added the new bamboo fence and put all the rocks back in place. Voila, it looks like new.

As a reminder, the photo below is what the pool looked like in 2019 when we originally installed it.

We are so glad our pool is ready to be used again and looking brand new. All we still have to do is add a bamboo protector to the pool surround.
Oh, and how about my Frank in the video? He loves having us out in the yard again. He’s also happy to have his roommate, aka my son, back to snuggle in bed with him every night.
Tschüß,
