[twixy]

Hi all,after giving my interpet pf4 filter a clean,a very irritating vibrating noise has started coming from the top end of it,taken it apart,checked the impellar and all is fine,any help or advice would be very much appreciated cos its driving me crazy

Don't really know but a lot of times those vibrations come from the lid. Perhaps some thin, small weather insulation that has stick-down tape on one side could be engineered to help.

Aqua Clear filters sometimes have a problem with a little buzz or rattle from the lid. I put a small piece of slate on top.
