After finding this site, I was inspired to build a cooling system (I am calling it my cooling wall) for my 18’ Intex metal frame pool and share the results. I was suffering from a HOT pool that defeated the purpose of having a pool to find comfort in this 100+ degree heat. So my mission was to find a way to split my output so I could pump water to my cooling system. Keep in my mind that the fitting I used were chosen as I had extra Intex hoses and plunger valves readily available (Just purchased the Sand Filter/Saltwater combo from Walmart after my Pump/SWG died last week).
On a good note, after running the cooling wall for 3 hours yesterday afternoon, I noticed a huge difference (It was actually refreshing and a bit nipply after I got out of the pool). Unfortunately, my thermometer seems to be stuck at 95 degrees. I was hoping to have reliable data to prove that the system works. The sound of rain is very much relaxing. Also, the kids love it. As a parent, I have designated one part of the pool a timeout area if any fights ensue.
I am also hoping for some feedback/advice on the following issues that I am facing and ideas that I have for the near future. Below are the issues/ideas.
1. I cannot run the fountain and outlet at the same time. The fountain pressure goes down to a trickle.
2.One idea is to get a separate pump to run the fountain or purchase the larger 2500 GPH sand filter pump. I am unsure if a 1500 GBH separate pump will be suffice to run the fountain. In this case, I would run this pump directly to my skimmer and the other pump to the inlet by using a similar split I used for the outlet then run each pump to the pool outlet and the fountain. I am concerned by using two different pumps that pump at different rates, would this bring forth other issues.
3. Splitter – my current t-split is 3” (I think). I am thinking by reducing this to 1.5” to 2”, it will increase my pressure.
4. When I run my fountain, my PSI is right at the green/yellow split. Is this good for my pump?
5. What is difference between hard plumbing versus the Intex hoses?
