The impeller on the housing for my pool pump sprung a leak and so I'm trying to replace it. I have the replacement housing, but I'm having trouble removing the old housing. The housing is thread connected at the top to the piping, and I can start to turn the housing to disconnect it, but there doesn't seem to be enough clearance to turn it very far, as shown in the picture below:
The housing is in the center, with the pipe coming out the top of it. The housing has turned just slightly counterclockwise to unscrew it from the piping, but is running against the plate attached to the filter basket to the left. There is not enough flex to turn it much further than this.
