I bought my 180i from Marine Depot. Chances are, any online dealer will turn you to the manufacture for warranty issues. The only way Marine Depot or BRS to honor warranty is if......
A) The item is unopened and you changed your mind. (Restock Fee)
B) The item arrives broken, but has not been used.
When I bought my Ecotech Vortech MP40, I opened it up and the white ceramic shaft was broken, never touched a drop of water. I was told to contact Ecotech......... which Ecotech took care of me to my satisfaction.
The Vortex skimmers are very tuff and high quality, I'm sure you will be happy with your purchase.
