RE: Robart check valve failures
I've had 2 failures with Robarts...same pin-hole deal.....switched to BVM's 1 year ago on all my planes and no problems since that time....
There have been postings of where you can get these valves a bit cheaper than BVM, but I usually pick them up at SM or FJ where he often has them marked down or on one of his monthly web site sales...
