Hayward chlorinator entraining air?

[dave42]

Just an update. No air at all in pump. Took cover off Hayward inline chlorinator and removed inner part to check oring. Oring was deformed. Replaced oring and air entrainment stopped. It seems that chlorinator creates Venturi effect and was pulling air into it. Just in case anyone ever has this problem.

Is your chlorinator an off-line or on-line model?

If it's upstream of your pump and filter, and is an on-line model, there are some issues you need to be aware of.

[dave42]

Chlorinator is in-line and is downstream of heater and filter (chlorinator is last piece of equipment before water return to pool).

[PoolDoc]

Well, it's fixed, so that's the main thing.

It's puzzling how an inline chlorinator, that's downstream of the pump, could let air into the piping with the pump running. But I can think of a couple of ways that is possible, so I'm not going to worry about it further.

Cross threading the cap when replacing it after refilling with pucks will do it.....
