Another simple item that can make or break a quick drafting set-up. Many of the floating suction strainer manufacturers use some type of pin or slide bar lock to secure the strainer in the float during storage. On some brands, it you forget to remove the pin or move the slide bar then there is a good chance that the strainer and float will come out of the water once the suction hose is full of water and thus....air will now sneak into your drafting set-up because a corner of the suction screen is out of the water. It is very easy for this to happen when in a rush to get that drafting operation set up. Review your strainers and know what needs "moved" or "pulled" in order to allow the float to swivel under the hose load once deployed. This beats having to pull the hose back in or sending the new guy out in the water to fix it!
With the slide locks in the "unlocked" position, the float works as designed and the suction hose pivots under load.
The set-up was fast....but the slide locks on the float were forgotten during deployment and now the strainer is sucking air on the one corner. Gotta bring that back to shore and fix it.
