Has anyone found that to be an issue? The pump is low enough I don't think it would lose prime, but it could get some air in it if it bled back down from the nozzles. Seems like it would only take a couple of seconds for the jets to work when a cycle is triggered as short a pipe run as I will have, but I would like to know before I pipe it, if it's going to be an issue.
