I bought a AquaC EV-120 skimmer but seems to be missing a air valve and has an extra hole on the opposite side, I was wondering if anyone has or had this skimmer seems to be the older style EV-120 any help would be appreciated.
Yeah, thats the older version of the EV-120. The new one has an blue and grey air valve and the exit gate is on the longer front and is a few inches higher.
