Review by Hencely on Sep 8, 2019

First winter with my pool used this kit opened my pool this spring my water was crystal clear. Took a sample to the pool store had it tested I didn’t need to add anything my pool was ready for swimming. I would definitely recommend this kit. The gentleman in the pool store said he had never had somebody come in and they did not need to add chemicals to their pool after opening it. He said whatever I’m doing keep doing it.

Great Product With Amazing Results

Review by Sam k. on Jun 5, 2019

This Product is amazing! I winterized my new Saltwater 8000 Pool back in September with the salt water winterizing kit, just opened my pool on June 3rd and the water was sparkling. Took a sample of pool water to my local pool company to get it tested, i was expecting to hear the usual run down of all the chemicals needed to get the water balanced, to my shock and the tech doing the test.. Everything was perfect! First time in my life I didn't have to spend any money opening my pool. Highly recommend this kit.

Extremely satisfied

Review by Dave W. New Jersey on May 19, 2019 Verified Purchase

Have ordered several times using the Pool Factory. Extremely satisfied so far. Purchased the Salt Water Winterizing Kit last September, followed the instructions along with the help of one of the agents online and just pulled the cover off May 18th '19 and the water looks crystal clear. Couldn't be happier, the kit must have done it's job. The salt level was just shy of what it should be, so made adjustments to that, checked the other levels, PH, Alkalinity and so on and they were spot on, NO adjustments were necessary. Also ordered a new 1 HP Hayward pump and it too is working perfectly. Pool Factory has so much to choose from and everything you could possibly need for your home pool. Thanks to all.

The start-up kit and the closing kit are amazing.

Review by Tammy C. on May 17, 2019 Verified Purchase

The start-up kit and the closing kit are amazing. We've used 3 years in a row. Take the cover off and the pool water is crystal clear except for some debri. Worth the money even when you pay for shipping! Bought our pool from here too and LOVE IT!
