Product details

This is the Waterway 670-2300, a 3/8 inch air injector from the Top Flo line. It is the genuine Waterway part.

Installation size

The injector needs a 1-3/16 inch hole to install. That is the one measurement to confirm before you order, because an opening cut for a different injector will not let this one seat and seal. The 3/8 inch in the name refers to the air line the injector takes, not the hole.

When to replace one

Air injectors live in a hard spot: constant wet, constant air, and whatever the water chemistry is doing. They scale up internally and eventually crack. The symptom is a weak or uneven bubble pattern that does not come back when you open the air control or clear the line. At that point the injector is the part to change, and swapping in a fresh one restores the pattern without touching the surrounding plumbing.

Questions and answers

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

What size hole does it need?
1-3/16 inches. Measure the existing opening before ordering, because the injector will not seal in a hole cut to another size.
What does the 3/8 inch refer to?
The air line size the injector takes.
Is this a genuine Waterway part?
Yes. It is Waterway part number 670-2300 from the Top Flo line.
Why has my air flow dropped off?
Injectors scale up and crack with age. If the air line is clear and the control is open, the injector itself is usually what has failed.
