well here is what I will try just for the sake of it. since they leak air from multiple sources I will inject water in the OUT nipple and try to visualize where how why they pass air backwards. Obviously a sealing issue
maybe I can fix them time permitting.
Could be just those metallic check valves not being seated deep enough . All other component & gaskets are squeezed and sealed by the 4 bolts when mounted. check valves must be the weak point
latest mail from the reseller today confirmed the manufacturer will not respect his warranty (past due) even as I explained that testing water pumps on frozen lakes in Canada was a problem … in March
one more reputation down the drain for 35$ worth ….. of bad pumps

how is the blow test on yours ..? physically I found nothing wrong but air flows see PM out seemingly from everywhere incl. the mounting holes.
actual air flow IN to OUT is next to impossible using my mouth …could be just check valves again. all my stuff is at the cottage…not accessible for now
there are lots of sellers ..did u get the $6.99 version
check PM
