Morning everyone! New to this forum and I am hoping if possible someone can solve my problem here! I have recently installed a controller and pump to a 300 litre tank and the pump is forever running yet no water is coming out. Initially I was getting dead ends and upped the controller to 99psi to get rid of any airlocks but it was just trickling out of the hose. I fully extended the reel and the pole but with no joy. I took of the hose to the reel to check if water was coming out and same again - not much water. I checked all the hoses from the tank to the pump and they were all fine. I lowered the pump position and no joy there either. I've basically tried everything what has been adviced on here but nothing is working and now the pump is constantly running without any sign of water yet there are no leaks or anything. Very stuck here so would appreciate any advice given! I'll attach a photo of my system. Many thanks.
