There is a good reason why we love Tunze as a product. They are super reliable and if service is required they action them well, very well.
Here is what happened.
A good customer of ours bought a Tunze pump on 20/08/2013 and installed it yesterday and after 4 hours it stopped and the customer noticed scoring on the impeller. The customer called us yesterday at 1.59pm - we talked to the Tunze supplier at 2.04pm and called the customer back at 2.17pm and mentioned that the supplier would like a photo of the impeller. The customer sent off the photo and at 12.41pm today the customer emailed us as well as the Tunze supplier thanking them as he had his replacement pump.
Less than 24 hour turn around from time of fault to replacement - absolutely awesome.
It was thought the the impeller cap that held the impeller in place was dislodged somewhere in transit.
So if you are thinking of pump and tossing up if you should get Tunze and if we recommend them - well we certainly do.
One major important factor, the Tunze pump was purchased through us, an authorised Tunze Retailer not through a grey importer, as grey imports are not warranted nor supported by the Authorised Tunze Distributor in Australia so you might want to consider this when purchasing Tunze and ask the question...
Pet City and Age of Aquariums are also listed as authorised retailers too.
