For nearly a century, pool professionals have answered water-chemistry questions the same way: test it with a Taylor. Founded in 1930 and based in Sparks, Maryland, Taylor Water Technologies is the recognized leader in water-testing kits and reagents for residential and commercial pools, with a catalog of nearly 600 test-kit configurations carried by hundreds of distributors across North America. Its famous K-2005 Complete Test Kit is the go-to tool of service techs everywhere, and Taylor reagents are produced fresh at the company's own facilities. Acquired by global pool leader Fluidra in 2021, Taylor continues to operate as the water-testing authority — it is even an Official Supplier to USA Swimming. For DIY homeowners, a Taylor kit means drop-count precision instead of guesswork, so every chemical you add is the right one.
