Slow Flowing Tap

NESSIEHUNTER

Hi, I am in the process of changeing the sink and taps in the kitchen, the problem is when it`s all been connected the flow from the hot tap is not very quick, the tap is a Franke Pilatus Powerstream, is this normal for this type of tap?.

Good afternoon: Is your hot water under mains pressure or gravity fed?

Hi, It comes from the water cylinder in the cupboard upstairs, so I would assume it is gravity fed.

have exactly the same on my new sink and tap...
The sink is a FRANKE not sure about the tap but it came with it,,
my hot water flow is about half that of my old tap.

Its a mixer type with one controll lever.

Hi...gravity fed then...whatever pressure you have now is as good as it gets unless you pump the hot water or swap everything to mains fed hot water...all of which will cost considerably more than changing the tap to one which will work better on gravity hot...consult the supplier and specify you have low pressure gravity hot.

The original taps I replaced had a great flow, I just thought maybe I had done something wrong when changeing them over.

Thanks for your help.

Hi there, I have heard some of the Modern Designer taps are suited for "trendy flats". IE, a modern water system with high pressure hot water. Im guessing there isn't enough flow in gravity fed systems (high volume, low pressure).

You will need to change the taps, as you will have fitted high pressure taps, not suitable for a gravity system.

Have been through this with Franke with the very same tap! The cold supply was fine but we couldn't get warm water because hot on it's own was fine but as soon as you put the cold water on even a whisker the hot was overwelmed. I wrote to them about it as their website said no ceramic disc taps were suitable under 0.5 bar (ie without 5 metres drop between the bottom of the tank and the tap) and asked for advice whether changing to a different tap would help. They wrote back:

A ceramic disc is the same as a ceramic valve so the Franke Planar tap requires a minimum bar pressure of .4. This would therefore not be a suitable for water pressure of anything less than this. You need to consider a tap with compression valve fittings such as these from the Professional Range: Rotaflow, Victorian, Retro, Bridge or from the Specialist Range: Helena CV (compression valve).

We've ended up with a low pressure tap from Sinks Taps.
