My Blacktip tech leaked last year when probably less than a dozen dives in. I suspect I'd been getting water in from the beginning. Has anyone had any success with their customer support/warranty? I'm in the UK and was essentially told there was no warranty at all against leaks and that they are 100% certain it was leak free when I purchased it so ergo I've done something to cause the leak. However, when I stripped it, I found a hair across the mechanical seal's sealing face (different colour to mine) and way too much grease, including over the sealing face - which should run in the medium it is immersed in. When I sent them the pictures they essentially told me that because I'd stripped it (conscious that all that had been offered before was that I pay shipping from the UK and back PLUS the repair cost) I again had no warranty and I shouldn't have stripped it, suggesting my actions were the same as taking a new car back to the store in bits...but what other option did I have?
On rebuilding and vac testing I also found the screen to be loose which they claimed was because I'd had water inside (I'm talking about 1/4 cup full not a complete flood, and a leak detector I'd installed meant I was able to bail and get it shallow nose down, so water would not have been running across the screen). If such a small amount of water will cause the screen to delaminate will it not delaminate over time anyway?
They have provided some customer support in as much as they have sold me the spares I need to rebuild it my self, but I have to say I'm very disappointed. I also very much suspect selling an underwater vehicle with no warranty at all against flooding is not legal here. I ran a Sierra for a decade and managed not to flood it.
I really like their product but fear I will be looking elsewhere for my next DPV.
