The Zodiac Union Kit ordered was what I needed for the pool. I needed to replace my existing coupler, to the filter housing, that had cracked and was leaking. Installation of the replacement was easy and uneventful. My only suggestion would be, however, that as opposed to more than replacement union being provided, that the customer be permitted to order what they need, although, candidly, I do not know if that would be cost effective. But I am happy to have the additional replacements contained in the box for future need.
Otherwise, I have ordered from Sunplay before, prior to this Zodiac Union Kit, and have found pricing to be competitive and shipping prompt. There were no problems on the order and I would order from Sunplay again.
