Hi,
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.
Thanks!

Hi @SimonB,
The teflon tape goes inside (on the threads) and needs to be applied clockwise. The following video might help:
Good luck!

@SimonB I had a similar issue and I opened it up to find no O-ring. The brass fitting is designed to seal using a square-profile O-ring as it is not tapered thread. The tape is likely to leak eventually but an O-ring will last without having to over crank and destroy the threads.
Hi,
When you say you opened ‘it’ up, does ‘it’ mean the solenoid? I’m not clear what an o ring is or how to recognise it.
Thanks!!

Sorry, yes, I see it. Inside the black pressure valve. Thanks for the suggestion.
Now it works perfectly! The plumbers tape, correctly applied, made all the difference.
May I suggest augmenting the instructions here:
To include details of using the tape?
