I did the "O" ring mod as well - not worth the bother or cost of a return to the supplier. Yes, it is under warranty, but is it really worth the cost and hassle for a repair that costs a few pence and is certainly not essential?

If it isn't essential why did you bother to repair it? Your right sending it back would be OTT but getting new parts under warranty is the least I would expect.

I'm kinda with DavidV here, if there's no pressure to improve the parts don't expect it to improve.
