My old foreman told me to always keep a spare pump seal in the tool locker, and I finally saw why.
We were on a job in Mobile Bay last month, pulling up oyster shells. The main pump started spraying water everywhere at 2 PM on a Friday. If I hadn't had that spare seal right there, we would have lost the whole weekend waiting for a parts delivery. He said, 'A seal is cheap, downtime isn't.' What's the one piece of gear you always keep a spare of on your rig?
