Where does this o-ring go?

[DFWBill]

Hello,
I just got my new Octo 160 last night and was putting it together. In the bag with the pump to chamber connector, there is a small white o-ring. In the instructions there are 3 o-rings shown, one on the pump side of this connector, one on the chamber side of the connector and one on the collection cup. As the unit came out of the box, these 3 were already in the indicated spots... so what's this one for? :confused:

Thanks,
Bill

We think it is an extra oring. There is only a need for the three. Is it a duplicate of the orange that hold the output of the pump to the body?

Hi Jer..

yes.... OK I'll go ahead and put it in the sump, didn't want to anything till I found out. I got it running in a bucket of water and there are no issues. I sorta thought it was a spare.

thanks for responding on a saturday man.
