I'm still having problems with my feed pump on the SC2060 skimmer.
I spoke with Stuart when I experienced the problems previously and he kindly sent me a tap to attach to the air intake and told me to set this to about 1 o'clock, which I did. Since then all appears to have been fine however I went away for 4 days at the weekend and on my return last night the skimmer was not working!
The person responsible for looking after my fish whilst I was away is a non fish keeper so won't have noticed it had stopped, so I can't say how long it hadn't been on. That said, when I took it apart last night the pump and impellor were still both pretty warm, so I presume it hadn't been off too long.
Stuart had previously mentioned that you were awaiting delivery of some new bearings that should resolve the problem.
My main concern is that as I'm out at work during the day etc, I'm not entirely sure if this is an ongoing problem, whereby the skimmer stops every so often or just a one off.
