My Buying Guides on 7 X 20 Feet Pool Liner
When I decided to upgrade my pool, one of the most crucial components I needed to consider was the pool liner. After some research, I found that a 7 x 20 feet pool liner was the perfect fit for my needs. Here’s my comprehensive buying guide that helped me make an informed decision.
Understanding Pool Liners
Before I began my search, I took the time to understand what a pool liner is and why it’s essential. A pool liner is a barrier that holds water in the pool and protects the structure from deterioration. It also adds a nice aesthetic touch to the pool area. I learned that choosing the right liner can significantly affect the maintenance and longevity of my pool.
Types of Pool Liners
While searching for a 7 x 20 feet pool liner, I discovered there are a few different types available:
- Vinyl Liners: I found these to be the most popular option. They are affordable, easy to install, and come in various colors and patterns. Plus, they are resistant to algae growth, which is a big plus for me.
- Fiberglass Liners: Although these are generally more expensive, I loved that they are durable and require less maintenance. However, they usually come as a complete pool shell rather than a liner.
- Tile Liners: These offer a beautiful aesthetic, but I found them to be pricier and more challenging to install.
Thickness Matters
One of the essential factors I considered was the thickness of the liner. Most pool liners range from 20 to 30 mils. I chose a 27 mil liner for my pool, as it provided a balance between durability and cost. Thicker liners tend to last longer and resist punctures better, which is something I wanted for my pool.
Patterns and Colors
I enjoyed exploring the various patterns and colors available for the 7 x 20 feet pool liner. I wanted something that would complement my backyard. I found that darker colors can absorb heat, while lighter colors can make the pool look larger. I finally settled on a beautiful blue tile pattern that added a touch of elegance to my pool.
Installation Process
When it came to installation, I had two options: DIY or hire a professional. I considered the DIY route since it would save me money, but I ultimately decided to hire a professional. They ensured that the liner was installed correctly, which gave me peace of mind knowing that it was done right.
Maintenance Tips
After installing my 7 x 20 feet pool liner, I learned some valuable maintenance tips. I regularly check the pH levels of the water, use a pool cover during the off-season, and clean the liner to prevent algae buildup. These simple steps have helped extend the life of my liner.
Cost Considerations
Finally, I had to factor in the cost of the 7 x 20 feet pool liner. Prices can vary widely based on the type, thickness, and design. I set a budget and compared several options online before making my final decision. I found that investing a little more in a high-quality liner was worth it in the long run.
Conclusion
Choosing the right 7 x 20 feet pool liner was an enlightening experience for me. By understanding the types, thickness, and maintenance involved, I was able to make an informed decision that I’m genuinely happy with. I hope my guide helps you navigate your pool liner purchase with ease and confidence!
