Leaking Hayward Chlorine Feeder

[ohherdfan]

I have a Hayward Chlorine Feeder that appears to have a very small crack in the top of the screw-on cap. It may also have a bad gasket. Is this common and are the caps available as a stand-alone replacement part?

Here's you a possible source, with diagram:

I've purchased from them, but I'm not recommending them specifically.
