Hyco Handyflow Undersink, When turned on, causes tap to drip

[Liam CH]

Hello! I have recently gotten my sink installed with the Hyco Handyflow Undersink. It works great and makes the water go hot. However when I turn it on to heat the water, it causes the tap to slowly drip. When i turn this off, it seems to stop dripping.

Would there be any indication what the problem is from anyone?

Sounds normal as the water is expanding when upto temp does it stop dripping ?

If thats just a “ normal “tap it doesn't sound right , post a pic of the pipework under the sink

The Hyco is supplied with a vented tap, so it will drip to relieve expansion when turned on.

I had to make an account to get the picture functionality working.

I'm not too sure how these work, so if this is normal then great! I don't know how long estimate it will take for the dripping to stop, i shall test that out now.

Here are the photographs

I've just had the heater on, and after about 10 - 20 minutes it's turned off, the dripping has stopped and the water is heated!

So my lack of understanding is my failure! As people have said, it's normal due to the vented tap and expansion of water. Once the water is heated, it stops the dripping stops also!

Sorry for the silly question!

its not a silly question,as if it was wrong you need to know, and get it sorted.

Make a sign up to tell as it’s common for people to try and keep turning the hot tap as it’s dripping and it breaks the tap
