Product details

The Hayward GLX-DIY-UNION is the replacement union kit for the Salt & Swim 3C Pro salt chlorination system. It is the genuine Hayward part.

What the unions do

The salt cell sits in the return plumbing on a pair of unions. Those unions are the reason the cell can be unthreaded for inspection, cleaning or replacement without cutting into the pipe. They are also the joint that gets worked the hardest, since every service visit means loosening and retightening them.

When to replace them

A union that weeps after the cell is reinstalled, a cracked union nut, or threads that no longer pull up tight are all signs the union has had enough. Fitting a fresh kit restores a clean, serviceable connection at the cell instead of chasing the drip with tape and sealant.

Questions and answers

What people ask about this product, answered by our pool techs.

Which system is this union kit for?
The Hayward Salt & Swim 3C Pro. Hayward lists it as part GLX-DIY-UNION.
Is this a genuine Hayward part?
Yes, it is the Hayward OEM union kit for the Salt & Swim Pro.
Does the salt cell come with it?
No. This listing is the union kit only. The replacement cell and the replacement vessel are separate Hayward parts.
Why would I need new unions?
Unions get unthreaded and retightened every time the cell is pulled for cleaning. Over several seasons the threads or the union body can crack and start to weep, and a new kit is the clean fix.
