I’m having problems with the connection between the first NPT to barb adaptor and the solenoid valve inlet. It leaks! The NPT screws on ok and I twist until it won’t go further. (I’m pretty sure I haven’t confused it with the hose adaptor). I’ve tried wrapping the whole of the tape roll round it, but still it leaks.
See the video:
Has anyone else had this? I wonder is the plastic thread might be defective, although it looks good to me. Wrapping in tape seems like a bit of a botch job anyway: I would have thought it’s essential to get a watertight screw connection first.
