leaking bath gooseneck hob spout

[Spassa]

 

• Hi I had leaks at the bottom of the sink tap mixer , also where the shower hose came out of tiles and at the bottom of the gooseneck bath spout .Replacing the cartridges has fixed all but the bath spout . I then replaced the bath spout o rings . I couldn’t get the cone shaped cover off I dont know if this is relevant . I have plumbers tape and plumbers grease I’m yet to try . But it’s a fairly decent leak more water leaks than fills the bath 
• im not sure why the cartridge replacement hasn’t worked 
• can someone explain what else I may need to consider please 
• the leak occurs when the wall mixer is  turned on for the water to flow no leak otherwise 
• a previous post by another member said only 2 O rings not 3 as the lower one is for the grub screw would this apply here as well
• okay I left the third O ring on as the groove above the 3rd O ring lines up with the grub screw and the half circle brass thing then put plumbers grease on and lots of plumbers tape now it’s not leaking but I haven’t put the half ring and grub screw back on

Welcome to the Bunnings Workshop community @Spassa. It's wonderful to have you join us, and many thanks for your question about attaching a bath spout.

Your spout appears to use three O-rings, with two located at the top and one at the bottom. There is also a slot, which is where the grub screw locates to lock the spout into position. The O-rings provide the seal and prevent water from leaking at that joint, while the slot allows the grub screw to engage and stop the spout from popping off under pressure.

If the O-rings alone are not sealing properly against the spout, it suggests that something in that area may be worn or deteriorated. If it is not currently leaking, that is a good sign, but I would still strongly recommend refitting the half ring and grub screw, as these components are what actually lock the spout in place. Without that locking mechanism, there is a real risk the spout could pop off the spigot under pressure.

Let us know how you go.

Please let me know if you have any questions.
