I have read other posts about these extendable spray taps but couldn't find what I was looking for, so forgive me if I'm repeating another post.
The problem is that our spray tap is leaking. When it's turned on full in the cold water only position water gushes from the side of the tap housing and when the tap is turned off (lever pushed right down) a small spurt of water comes out between the swivelling leaver and the tap housing. This stops when the lever is rotated slightly (as if you wanted warmer water). Obviously something is amiss inside the housing, but I have no idea how to take it apart and I don't want to damage it. What do I do (after turning off at mains) to dismantle the housing, which looks like two large stacked chrome rings (spout protrudes from lower ring), with the swivelling leaver on top? I suspect I get a big wrench and turn something, but which part turns? Thank you.
Yes, you're quite right, I am Downunder. Thanks to your tip I now have the model: Look Tapware's BLIKK Sink Mixer with Pull-Out Spray WELS 4 Star 7L (Google " looktapware.com.au/product.php?key=br_sinkmixerpos". I have sent them an email requesting info but I suspect they will either tell me to ring a local distributor or otherwise just get a plumber. I appreciate your help so far and if you can tell just from the picture how I should dismantle this tap I would appreciate your opinion. I'll let you know what the manufacturer comes up with. Thanks Rosebery.
