Tunze 9012 foaming stops randomly

[david.faik]

My skimmer sometimes just stops producing foam. I have to blow in the air pipe, then it trundles along happy for 2-7 days before stopping again.

I cleaned and soaked in vinegar, but to no avail.

Anyone had similar and fixed it?

Works fine but when away I have to remind someone to come in and check this. Worries me, as I need the skimmer rock solid reliable :-S

For clarity the pump continues working, just no foam until I blow in the air inlet tube after which it kicks out foam again, straight away

Thanks in advance any wise people with good ideas!

How old is it?

Main thoughts are a bad impeller that is riding too high or an obstruction by salt creep of the air inlet nipple over the impeller.

About two years old, and it sat around before I used it (so over guarantee). Not sure what an impeller is, are you suggesting replace the pump? If you can advise what part I'll have a look on flea bay. Thanks

We have only made the 9012 for about 20 months, it is definitely under warranty, this is the part you need-
