Bait pumping fresh lugworm the key to success is getting that suction right. Started the morning changing the copper tube plus the seal so before going lugworming i had to set the pressure up correctly which is trial and error. For some one with experience it does not take long but for the beginner it can be a nightmare. once the pressure is set half the battle is done and its a case of finding the depth of the worms and learning your own style
the seals are made from no nonsense 820 silicone sealant which you can get from screwfix very cheap
I make my own pumps 22mm copper or stainless only
the bucket is a livewell bait bucket 12l https://www.decathlon.co.uk/p/12l-live-bait-fishing-bucket/_/R-p-197953
