Swan style tap issue

[Longpier]

Hi all

My plumber has installed some new Blanco mixer taps in my kitchen - they are the Cleo II range (swan neck type).

When the tap shuts off a little spurt of water comes out - but only on the cold tap. Here's a video to explain better:

Is this OK? Or should I get him back to do something? If the latter, what's the issue?

Thanks in advance,

James

Cant see the problem the water stops after it discharges itself.

I would suggest it's a faulty cartridge who supplied the tap.
If you supplied the tap the guarantee is your responsibility you need to contact the supplier.
If your plumber supplied the tap then contact him.

Thanks Steve - it's the kitchen firm who have supplied the tap. The installer said "this is just the way it is because swan taps retain some water" but I'm not convinced, especially as the hot tap doesn't do it.

They are new taps and he's coming back tomorrow

Interesting to note this nortonj. The issue as I see it is there should be no spurt of water after it's turned off. Does this happen always with swan taps?

Tighten the black plastic discharge nozzle...its pizzing water out.

Thanks Steelemasons. Have tried that but no luck sadly. Any other ideas?

It's fine. It's a dual flow tap where the water mixes at the end of the spout not in the tap body. The cold water has the wider outside channel and when you turn the cold tap off, air entering the wider part of the spout breaks the vacuum and lets the water that's left at the top spout run out.
The narrower internal channel holds the water as the air can't enter through the narrower part of the spout as easily and let it empty.

Thank you Madrab, very helpful indeed. Appreciate you taking the time to answer.

Its called the capillary action because when you stop the cold water flowing it drags the remainder out like a syphon.
