So i made a PVC overflow to help drain my tanks. I want to attach the hose to the overflow and run it into the bath tub. I have made two one with 3/4 inch and one with 1/2 inch PVC and the garden house is 5/8 inch. I am having no issues with the 1/2 inch. I bought a pvc adapter that has thread for the house adapter I bought a watts 3/4 fh x 1/2 mip A-677 GH6 hose adapter. If fits the pvc threads great and the hose. I am having trouble with the 3/4 inch PVC adapter. I bought the watts 3/4 MH x 3/4 FIP HOse adapter A-669 GH4 and it doesn't fit the hose or the pvc thread. What do i need to get it right? Thanks
