Title: New kitchen tap doesn't stop dripping for 10 secs?
Post by JMD6 on Oct 15^th, 2013, 12:27pm

I ordered the SOLACE Joyou (http://www.joyouinternational.com/en/40/kitchen-mixers/cosmopolitan/solace/) kitchen mixer taps and had them fitted by a large established plumbing company. I am experiencing a problem with the cold tap not shutting off immediately. It runs on for about 10 seconds afterwards (this runs approx. 40ml of extra water). I have had the company back out and they said that because of the design of the tap (large loop), this holds water after it is shut off and it is this water that is running out.

I know nothing about plumbing but this does seem odd to me and isn’t great at ‘water saving’. Strangely the hot tap shuts off immediately??
Are they correct on what they are saying or should I get them back out again to look at it.

Any help/advice would be greatly appreciated!
Thanks in advance. Best regards

Hi,

That are correct or more than likely to be.

What is happening the water is holding in the spout under a vacuum then lets go and the water runs out.

The reason the hot doesn't do it, is because it comes from a separate tube, in the center of the cold.

Give the tap (spout) a little tap next time you turn them off.

Thank you for your very quick response - appreciated.

I'll try a little tap when I get home tonight!

I would suggest 40ml of water is a very small amount and probably typical for many kitchen mixer taps. I bet most people waste many times that running the cold tap before putting their glass under it.

According to one water co we each use an average of 160 litres of water each day at a cost of 55p. That means water costs about 0.3p per liter. So each 40ml wasted costs only 0.012p I suppose if you used the tap 100 times a day that works out at about 1.2p a day or £4.40 a year.

You may find that as the tap scales up slightly the spout starts to hold some of the water rather than allowing it to drain out. But would you really want to drink water that's been sitting in the spout? It might have come from the hot feed depending on who used which tap last.

It's possible to worry too much about water saving :-)

round here water is £190 a ton or 1000L or 1p= 5.26L

Thank you for your advice re the amount of water I'm lossing - it's not a lot when you do the calculations.

The main thing I wanted to check was if the pulmber was correct in what he was saying about the tap drippping even though this doesn't happen with the hot tap. Do you have thoughts on this? I just want to feel like they aren't trying to take advantage because I know nothing technical about plumbing!

Thanks for your time, best regards
